Description

Positioning system and method based on conductive silica gel

Technical Field

The invention relates to the field of pressure sensing real-time positioning, in particular to a positioning system and a positioning method based on conductive silica gel.

Background

1. At present, in the application of a moving object for pointing, a camera or an infrared sensor is generally used to capture the moving object. For example: the real people's of VR walking needs to use the camera to catch the distance and the speed that the people walked, and the distance that can't accurate personnel moved is caught to this process inside of catching, if use infrared to catch, receives the interference of outside light very easily again. The camera and the infrared light and other rays are easy to shield, when a person is in front, the person or object behind the person can be shielded, and whether an object exists in the shielded area can not be identified.

2. Triggering of the pressure signals at multiple points monitors the collective movement speed, direction and intensity of multiple objects: when we are in an area, the action direction and speed of a certain object need to be obtained. It is now necessary to mount corresponding direction and speed sensors on the moving object, or to mount cameras to scan the direction and speed of the object, and to obtain the data from these sensors. When a plurality of objects need to flow through the area to receive the flowing speed, direction and density of the objects, the corresponding various sensors need to be installed on each object, the operation is very inconvenient for the flowing objects which change at any time, and the cameras are easy to generate shielding among the objects with different heights when the speed, the direction and the density of the objects are checked by installing the cameras.

3. Matching real and virtual regions: at present, VR technology is developed, people are usually tied by a belt in a fixed place when playing a VR virtual world, then the people move in a disc area, some disc bases can move, the walking direction is reflected in the virtual world, however, the experience of people is not very appropriate, when people walk on a disc, the experience people need to be tied by the belt to prevent the people from falling, and meanwhile, the incongruent and the inequality of walking cannot be completely reflected by matching the virtual world on the walking feeling. Within some VR educational and gaming content, real people are required to walk, for example, to which area they really walk, then to handle something, and then to return to a certain point. To achieve this, it is necessary to lay pressure checking equipment on the ground. Such as carpet, floor covering, floor lining. Pressure sensors (e.g., capacitive pressure sensors, resistive pressure sensors, inductive pressure sensors, etc.) are used to check pressure, but if existing pressure sensors are densely paved in an area, the thickness of a carpet, floor mat, or floor slab is increased above the volume. Meanwhile, the sensors are very expensive and are single-point signal transmission, for example, one point needs 2 lines of a power supply and 2 lines of signals, all signals need to be collected, and the number of lines on the controller for collecting the signals is very large, so that the cost of the equipment is greatly increased. Through the mode that uses conventional sensor, go to lay ground, then will have two kinds of voltages of positive negative in the region, if the circuit is broken or the short circuit, have the hidden danger that the circuit generates heat and fires, danger coefficient is higher.
