It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
It should be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the utility model discloses driver fatigue system is prevented to vehicle can improve the vehicle and prevent driver fatigue system's imaging quality. The embodiments of the present invention will be described in detail below.
Fig. 1 is a schematic structural diagram of a vehicle fatigue driving prevention system provided by an embodiment of the present invention. As shown in fig. 1, the system may include: a high-transparency polycarbonate panel 110, an optical isolation sleeve 120, and a camera assembly 130.
Among them, the high-transparent polycarbonate panel 110, which may also be referred to as a high-transparent PC panel 110, may include: opaque ink coated areas, infrared transparent ink coated areas, and uncoated areas.
The opaque ink coating area, i.e., the area where the opaque ink coating is added to the high transmittance PC panel 110, is such that no light can penetrate from the inside out or from the outside in.
The infrared transparent ink coating area is the area where the infrared transparent ink coating is added on the high-transparency PC panel 110. An Infrared (IR) transparent ink coating, which may also be referred to as an IR (Infrared Radiation) transparent ink coating, selectively transmits Infrared light waves in a desired spectral band and selectively shields undesired light waves. After the infrared light-transmitting ink coating is added on the high-transmittance PC panel 110, only infrared light can be allowed to pass through the region.
The uncoated areas, i.e. without any treatment of the high transmittance PC panel, allow light of any wavelength to pass through and have a light transmittance of more than 90%.
One end of the optical isolation sleeve 120 is connected with the edge of the uncoated area in a sealing way, and the other end is sleeved on the camera assembly 130. For example, any sealing process may be used to sealingly attach one end of the optical isolation sleeve 120 to the edge of the uncoated region.
The optical isolation sleeve 120 may be a black light-shielding material. The black shading material can effectively prevent light from diffusing, thereby reducing visible light loss and improving imaging quality.
As shown in fig. 1, when natural light passes through the uncoated area of the high-transmittance PC panel 110 and enters the camera assembly 130 through the optical isolation sleeve 120, infrared light is unidirectionally supplemented to the image capture object by the infrared light through the IR transparent ink coating, and at the same time, the opaque ink coating filters out all of the natural light, thereby preventing light pollution to the infrared light and the inside of the camera assembly 130.
After acquiring a sufficiently clear image, the camera assembly 130 may send the image to a background image processing and analyzing system, the image processing and analyzing system processes and analyzes the image to obtain a basis for vehicle fatigue prevention early warning and interference judgment, and finally performs fatigue prevention early warning and interference on the vehicle and the driver according to a data analysis result.
For example, the image captured by the camera assembly 130 may be subjected to face detection by the image processing and analysis system, and the driver's posture information in the vehicle may be determined, and when the posture information matches a preset posture, the driver may be determined to be in a fatigue state. For example, the image processing and analyzing system may perform face detection on the image through a fast Region-based Cellular neural network (fast Region Cellular neural network) face detection framework to determine the pose information of the driver in the image. The attitude information may be, for example: whether the driver is upright on his back, whether the eyes are continuously open, etc. The preset posture information may include, for example: sitting upright, forward looking, etc.
When the image processing and analyzing system determines that the driver is in a fatigue state, an early warning interference signal can be output. For example, the warning interference signal may include: play a prompt message through the vehicle voice system, send a notification message to a pre-stored communication address, and the like.
Therefore, the fatigue driving prevention system for the vehicle provided by the embodiment of the invention can comprise a high-transmittance polycarbonate panel, an optical isolation sleeve and a camera assembly; a high-transmittance polycarbonate panel comprising an opaque ink coated region, an infrared light-transmissive ink coated region, and an uncoated region; optical isolation sleeve, one end and regional edge sealing connection of uncoated, the other end cup joints in camera subassembly, therefore visible light sees through uncoated regional back, can get into camera subassembly through optical isolation sleeve and carry out the sensitization formation of image, because uncoated region is the high polycarbonate material that passes through, its luminousness is high, and optical isolation sleeve can stop the diffusion of visible light to can reduce the visible light loss, improve the imaging quality. And, infrared printing ink coating region can allow the infrared light to see through to can carry out infrared light filling for shooting the object, improve the imaging quality. The opaque ink coating is added in the region outside the infrared transparent ink coating region and the uncoated region, and transparent visible light in the opaque ink coating region can be prevented, so that interference on infrared light supplement is avoided, the infrared light supplement effect is guaranteed, and the imaging quality is further improved.
In one implementation, as shown in fig. 2, a schematic diagram of a structure of a high-transparency polycarbonate panel 110 is shown.
As shown in fig. 2, in the high-transmittance polycarbonate panel 110, the uncoated region 111 may be a central circular region of the high-transmittance polycarbonate panel 110. That is, the uncoated region 111 may be a circle having a center located at the geometric center of the rectangle in which the high-transmittance polycarbonate panel 110 is located.
The ratio of the diameter of the central circular area where the uncoated area 111 is located to the width or length of the high-transmittance polycarbonate panel 110 may be a preset value. That is, the size of the uncoated region 111 may be adjusted according to the size of the high-transmittance polycarbonate panel 110.
The uncoated area is arranged in the center of the high-transmittance polycarbonate panel and is a circular area, so that the uniformity of light rays entering the camera assembly can be improved, and the imaging quality is improved.
The infrared light transmissive ink coating region 112 may include: two symmetrical circular areas are arranged on two sides of the central circular area along the length direction of the high-transmittance polycarbonate panel 110; the two circular areas do not overlap the central circular area. Wherein, the size of the two circular areas where the infrared light-transmitting ink coating area 112 is located and the size of the central circular area can be the same or different.
