The embodiment of the application provides a gas control method, gas equipment and a storage medium. Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a gas control method according to an embodiment of the present application, where the method is applied to a gas device, and the gas device may be a gas burner or a gas water heater. As shown in fig. 1, the gas control method specifically includes steps S101 to S103.
S101, acquiring position information of a hand of a user through a non-contact acquisition device, and determining the fingertip position of the hand according to the position information of the hand.
The non-contact acquisition device may be a device for non-contact detection of position information of the hand, and the position information may be data for representing the position of the hand. For example, the non-contact acquisition device may be a camera, may be a 3D camera. The location information may include image information and may also include image depth information.
The user may interact by making hand movements when interaction with the gas appliance is desired. The user typically places the hand within the collection range of the non-contact collection device so that the non-contact collection device can collect the position information of the user's hand. After the gas equipment acquires the position information of the hand of the user through the non-contact acquisition device, the user knows that the user needs to interact with the gas equipment.
The position relationship between the hand of the user and the non-contact acquisition device can be determined according to the position information of the hand, the hand generally comprises fingers and a palm, and the position information of the fingers and the palm can also be determined according to the position information of the hand. The finger tip is the region of the finger furthest from the palm, so that the position information of the finger tip of the hand can be further determined.
In one embodiment, the operation of determining the fingertip position of the hand from the position information of the hand may be performed by:
determining the position information of fingertips of the hand according to the position information of the hand; and determining the fingertip position according to the fingertip position information.
Wherein, each area of the hand may be determined according to the position information of the hand, for example, including a finger area and a palm area, and the finger area may be divided into a first joint area, a second joint area and a third joint area. The sub-region far away from the palm in the finger region is determined as a fingertip, and the position information of the fingertip is acquired, so that the fingertip position can be determined according to the position information of the fingertip.
The fingertip position may be a position in a preset coordinate system, for example, the preset coordinate system may be a three-dimensional coordinate system, the X-axis and the Y-axis are located on a horizontal plane, the Z-axis is perpendicular to the ground, and the palm center may be used as an origin, or the non-contact acquisition device may be used as an origin. The type and specific setting of the preset coordinate system may be determined according to practical situations, and are not limited herein.
S102, determining a target graph according to the fingertip position, and determining size information of the target graph.
Wherein, the fingertip is the edge area of the hand, the target graph determined according to the fingertip position is associated with the hand shape, and the size information of the target graph is also associated with the size information of the hand shape.
The target pattern corresponds to the fingertip position, and illustratively, a polygon is determined as the target pattern according to several fingertip positions; it is also possible to determine a circle based on fitting algorithms for several fingertip positions such that the sum of the distances of several fingertip positions and the edge of the circle is minimized.
The size information is information for representing the size of the target pattern, and may alternatively include an area and may also include a perimeter.
The more open the finger, the more spread the positions of the several fingertips, the larger the target pattern, and the larger the corresponding size information of the target pattern. The closer the fingers are, the smaller the target pattern is, and the smaller the size information of the corresponding target pattern is.
In one embodiment, the operation of determining a target graphic from the fingertip position may be implemented as follows:
determining at least three vertexes according to the fingertip positions, wherein each fingertip position corresponds to one vertex; and determining the polygon formed by the at least three vertexes as a target graph.
Wherein three points may form a plane, three vertices may form a triangle, and four vertices may form a quadrilateral. At least three vertices are thus determined from the fingertip position, which may form a polygon, which may then be determined as the target graphic. The finger tip positions of at least three finger tips of the hand may be determined based on the position information of the hand, and a vertex may be determined based on the finger tip position of each finger tip. The determined at least three fingertips may include fingertips of any finger, not limited herein.
As shown in fig. 2 to 4, three vertexes may be determined according to the thumb tip 11a, the middle finger tip 11b, and the small finger tip 11c of the hand 10, the three vertexes constituting the triangle 11, and the triangle 11 may be determined as the target pattern. The fingers of the hand 10 in fig. 2 are relatively open, so the triangle 11 in fig. 2 is relatively large, the fingers of the hand 10 in fig. 3 are relatively close, so the triangle 11 in fig. 3 is relatively small, and the finger placement of the hand 10 in fig. 4 is relatively conventional, so the triangle 11 in fig. 4 is relatively moderate.
S103, adjusting the firepower of the gas equipment according to the size information of the target graph.
The larger the fire power of the gas equipment is, the more gas is used in a certain period of time, and the fire power of the gas equipment can be adjusted by adjusting the gas outlet quantity of the gas equipment. For example, an electromagnetic valve for adjusting the gas outlet amount is arranged in the gas equipment, and an adjusting instruction can be sent to the electromagnetic valve, so that the electromagnetic valve can adjust the firepower of the gas equipment.
The size information of the target graph can reflect the hand interaction action of the user, so that the interaction intention of the user can be determined, and different interaction intentions correspond to different firepower adjustment intentions. The corresponding relation between different size information and different adjustment instructions can be predetermined, and after the size information of the target graph is determined, the corresponding adjustment instruction can be found according to the corresponding relation, so that the firepower of the gas equipment can be correspondingly adjusted.
Alternatively, the fire power of the gas equipment can be continuously adjusted, or the fire power of the gas equipment can be adjusted to a preset value.
In one embodiment, the adjusting of the fire power of the gas device according to the size information of the target pattern may be implemented as follows:
if the size information of the target graph accords with a first preset condition, the firepower of the gas equipment is reduced; and if the size information of the target graph meets a second preset condition, increasing the firepower of the gas equipment.
The first preset condition may be a condition corresponding to a hand interaction for reducing the fire power of the gas appliance, and the second preset condition may be a condition corresponding to a hand interaction for increasing the fire power of the gas appliance. If the size information of the target graph accords with the first preset condition, the hand action of the user corresponds to the hand interaction action for reducing the firepower, and the firepower of the gas equipment is reduced; and if the size information of the target graph meets the second preset condition, the hand action of the user corresponds to the hand interaction action for improving the fire power, and the user is indicated to want to improve the fire power of the gas equipment. By judging whether the size information of the target pattern meets the first preset condition or meets the second preset condition, it is possible to determine how to adjust the fire power of the gas equipment.
Optionally, when the fire power of the gas equipment is reduced, the fire power of the gas equipment can be reduced to a preset value, the fire power of the gas equipment can be reduced according to a preset proportion, and the fire power of the gas equipment can be continuously reduced. When the firepower of the gas equipment is improved, the firepower of the gas equipment can be improved to a preset value, the firepower of the gas equipment can be improved according to a preset proportion, and the firepower of the gas equipment can be continuously improved. The specific lowering mode and raising mode may be set according to practical application requirements, and are not limited herein.
According to the method and the device for adjusting the gas equipment, the target graph can be determined according to the fingertip position of the hand of the user, the hand action of the user is determined according to the target graph, and then the interaction intention of the user is determined to correspondingly execute the operation of adjusting the gas equipment.
In one embodiment, if the ratio of the size information of the target pattern to the preset size information accords with the first ratio, determining that the size information of the target pattern accords with a first preset condition; and if the proportion of the size information of the target graph and the preset size information accords with a second proportion, determining that the size information of the target graph accords with a second preset condition, wherein the first proportion is smaller than the second proportion.
And comparing the size of the target graph with preset size information to judge whether the action on the hand of the user corresponds to the hand interaction action for adjusting the firepower of the gas equipment.
The preset size information may be preset size information, and if the ratio of the size information of the target graphic to the preset size information accords with the first ratio, it is determined that the size information of the target graphic accords with a first preset condition. And if the proportion of the size information of the target graph and the preset size information accords with the second proportion, determining that the size information of the target graph accords with a second preset condition.
Illustratively, the preset size information may be size information of a target graphic corresponding to a normal hand motion; the first ratio may be less than 1, that is, if the user gathers the fingers, the ratio of the size information of the corresponding target graphic and the preset size information accords with the first ratio; the second ratio may be greater than 1, i.e., if the user opens the finger, the ratio of the size information of the corresponding target graphic and the preset size information corresponds to the second ratio. Alternatively, the first ratio may be 70% or less and the second ratio may be 130% or more.
In one embodiment, the acquiring, by the non-contact acquisition device, the position information of the hand of the user may be implemented as follows: continuously acquiring the position information of the hand of the user through a non-contact acquisition device; the method further comprises the steps of: determining size information of a target graph corresponding to the position information of the hand acquired at the initial time as preset size information; if the proportion of the size information of the target graph corresponding to the position information of the hand obtained after the initial time and the preset size information accords with a first proportion, determining that the size information of the target graph accords with a first preset condition; and if the proportion of the size information of the target graph corresponding to the position information of the hand obtained after the initial time and the preset size information accords with a second proportion, determining that the size information of the target graph accords with a second preset condition.
The non-contact acquisition device is used for continuously acquiring the position information of the hand of the user, so that the change of the hand action of the user can be acquired. The method comprises the steps of acquiring position information of a hand of a user at an initial time, determining a fingertip position of the hand according to the position information of the hand at the initial time, determining a target graph according to the fingertip position, and determining size information of the target graph, wherein the size information of the target graph at the initial time can be acquired and can be used as preset size information.
If the position information of the hand obtained after the initial time and the ratio of the size information of the target graph determined according to the position information of the hand and the preset size information accords with the first ratio, the change of the hand action of the user can be determined, the change of the hand action accords with the hand interaction action corresponding to the reduction of the firepower of the gas equipment, and the size information of the target graph can be determined to accord with the first preset condition.
If the position information of the hand obtained after the initial time and the ratio of the size information of the target graph determined according to the position information of the hand and the preset size information accords with the second ratio, the change of the hand action of the user can be determined, the change of the hand action accords with the hand interaction action corresponding to the reduction of the firepower of the gas equipment, and the size information of the target graph can be determined to accord with the second preset condition.
In one embodiment, after adjusting the fire power of the gas device according to the size information of the target pattern, the method further comprises:
and if the ratio of the size information of the target graph to the preset size information accords with a third ratio, stopping adjusting the firepower of the gas equipment, wherein the third ratio is smaller than the second ratio and larger than the first ratio.
After the firepower of the gas equipment is adjusted according to the size information of the target graph, the position information of the hand of the user is continuously acquired through the non-contact acquisition device, and if the proportion of the size information of the target graph and the preset size information is detected to be in accordance with the third proportion, the firepower of the gas equipment is stopped being adjusted.
The third ratio is less than the second ratio and greater than the first ratio. If it is detected that the ratio of the size information of the target pattern and the preset size information matches the third ratio after the lowering of the fire power of the gas equipment is performed, that is, the user's finger is released, the lowering of the fire power of the gas equipment may be stopped. And if the ratio of the size information of the target graph to the preset size information accords with the third ratio after the firepower of the gas equipment is improved, namely the fingers of the user are gathered, the firepower of the gas equipment can be stopped being improved.
Alternatively, the first ratio may be less than or equal to 70%, the second ratio may be greater than or equal to 130%, and the third ratio may be less than 130% and greater than 70%. For example, as shown in fig. 2 to 4, the user may make the hand motion in fig. 4 at the initial time, that is, compare the conventional hand motion, and size information of the target graphic 11 determined as the initial time may be used as the preset size information. If the user wants to reduce the fire power of the gas equipment, as shown in fig. 3, the user can draw fingers together, the size information of the corresponding target graph 11 becomes smaller, and if the ratio of the size information to the preset size information is less than 70%, the fire power of the gas equipment can be determined to be reduced; if the user wants to increase the fire power of the gas equipment, as shown in fig. 2, the user can open the fingers and the size information of the corresponding target pattern 11 becomes large, and if the ratio of the size information to the preset size information is more than 130%, it can be determined to increase the fire power of the gas equipment. If the user wants to stop adjusting the fire power of the gas appliance, the hand motion may be restored to the motion as shown in fig. 4, and if the ratio of the size information of the target pattern corresponding to the restored hand motion to the preset size information is less than 130% and more than 70%, that is, the hand motion indicating that the hand motion of the user is restored to the initial time, the adjustment of the fire power of the gas appliance may be stopped.
