[0026] In order to make the objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0027] Reference Figures 1 to 5 , a table type fatigue prevention camera provided by an embodiment of the present application is shown, which comprises a camera assembly 10 and a support assembly 20; the support assembly 20 comprises an upper support 21 and a bottom support 22; the camera assembly 10 is installed on the top plate 214 of the upper support 21; the upper support 21 is provided with first side plates 211 on both sides, and the first side plates 211 are provided with first pivot connection holes 212 and first limiting holes 213; the bottom support 22 is provided with a bottom plate and a second side plate 221; the second side plate 221 is provided with a second pivot connection hole 223 and a first arc-shaped waist hole 224; the bottom plate is provided with a middle hole 222 at the middle position and second arc-shaped waist holes 225 at both sides; the upper support 21 and the bottom support 22 are pivotally connected through the first pivot connection hole 212 and the second pivot connection hole 223 and screws, and the first limiting hole 213 is provided with a limiting column or a limiting screw extending to the first arc-shaped waist hole 224. The first side plate 211 can be located inside the second side plate 221, or the second side plate 221 can be located inside the first side plate 211, the first pivot connection hole 212 and the second pivot connection hole 223 are connected through a connecting shaft or a screw, so that the camera assembly 10 installed on the upper support 21 can be rotationally adjusted relative to the bottom support 22; the rotation angle of the camera relative to the bottom support 22 can be limited through the above-mentioned first arc-shaped waist hole 224; the above-mentioned bottom plate is installed on a target through the middle hole 222 and a screw, and the bottom support 22 can drive the above-mentioned camera assembly 10 to be rotationally adjusted based on the above-mentioned middle hole through the cooperation of the second arc-shaped waist holes 225 on the side and the screw, so that the camera can be adjusted in multiple directions, and it can be conveniently adjusted even after installation. Meanwhile, the side plates of the above-mentioned support assembly 20 make the bottom support 22 and the upper support 21 not only have an adjustable function, but also have a stable connection structure.

[0028] In this embodiment, the problem of inconvenient adjustment of the angle after installation is solved by a unique support assembly structure. The upper support 21 and the bottom support 22 are connected in a pivoted manner, specifically, the first pivoted hole 212 and the second pivoted hole 223 and the screw are used to realize pivoting, so that the upper support 21 can rotate relative to the bottom support 22 around the pivoted part, thereby driving the camera assembly 10 installed on the top plate 214 of the upper support 21 to realize angle adjustment. Compared with the situation that the angle cannot be flexibly adjusted after the traditional fixed camera is installed, the above structure of the present application provides an effective structural basis for camera angle adjustment, so that the angle can still be changed as needed after installation; in addition, in addition to pivoting, a limiting structure is also provided between the upper support 21 and the bottom support 22, a limiting column or a limiting screw extending to the first arc-shaped waist hole 224 is arranged in the first limiting hole 213. After the angle of the camera is adjusted, the relative excessive movement between the upper support 21 and the bottom support 22 is limited, so as to avoid the angle of the camera from being randomly changed due to accidental stress and the like, and the stability of the adjusted angle is ensured. On the other hand, the bottom support 22 is provided with a second arc-shaped waist hole 225 at both sides of the bottom plate, and a middle hole 222 is arranged in the middle part, so as to further enable the camera to be limited and adjusted relative to the installation target. The first side plate 211 and the second side plate 221 are symmetrical on both sides to ensure the stability of the support, and the top plate 214 and the bottom plate enable the camera assembly 10 to be stably connected with the support assembly 20, and the support assembly 20 and the target to be stably connected, overcoming the defect of insufficient stability of some conventional adjustable supports.

[0029] In the embodiment of the present application, the camera assembly 10 comprises a camera 11 and at least one set of fill light 12; the fill light 12 is arranged on the side of the camera 11, as shown in Figure 3 By arranging the same fill light 12 symmetrically on both sides of the camera 11, the fill light effect can be balanced.

[0030] In the embodiment of the present application, the camera 11 is a visible light camera and / or a thermal imaging camera. The camera 11 can be a single visible light camera, a single thermal imaging camera, or a dual camera of visible light and thermal imaging. When the thermal imaging is used alone, since the imaging principle is to image the degree of infrared reflection through the activity degree of infrared, it can be regarded as imaging of temperature, so the fill light 12 described above can not be used for fill light. When the fill light is used, the camera 11 described above is a visible light type camera 11.

[0031] In the embodiment of the present application, the group of light supplementing lamps 12 is a dot matrix LED lamp group, which can use mixed white light LED and infrared LED for light supplementing. When the camera switches to color mode, white light supplementing is started, and when the camera starts black and white, infrared supplementing is started. The above-mentioned LED lamp group can specifically use COB lamp beads, or each COB lamp bead can reach 3W. As shown in Figure 1 and Figure 3 Each group can be provided with 12 COB lamp beads, so that it can reach 72W. The COB lamp bead has the advantage of high brightness, as a surface light source, the light emitting angle is large, and the light distribution is more uniform, without obvious light spots and dark areas.

[0032] In the embodiment of the present application, the front end of the light supplementing lamp 12 is provided with a transparent cover plate 13, which not only protects the light supplementing lamp 12, but also plays a waterproof and dustproof role. The above-mentioned table type fatigue-resistant camera can also be provided with a heating assembly, a fan and a temperature sensor; the heating assembly, the fan and the temperature sensor are electrically connected to the circuit board. It is used for adjusting according to the temperature inside the equipment, so that it can work stably. For example, a temperature threshold can be set. When the temperature is lower than 0℃, the heating camera is started to heat. Since the light supplementing lamp array 12 itself can generate heat when working, only a lower power heater needs to be set, for example, a heater with a heating power of 5-10W can be set. When the temperature is higher than 40℃, the fan is started to dissipate heat and prevent the temperature from being too high. The above-mentioned table type fatigue-resistant camera is mainly applied to the problem of detecting whether the driver exists fatigue driving in the vehicle. The angle can be adjusted according to the body shape of the driver. Compared with the controllable rotating camera, there is no need to worry about the problem of angle deflection of the camera position due to power failure reset. In the light supplementing lamp 12 of the above-mentioned camera, an infrared light supplementing lamp is preferably used. The above-mentioned camera 11 is preferably a black and white camera. The above-mentioned cover plate 13 preferably uses a polarizing plate to prevent the light of the light supplementing lamp 12 from directly shining into the eyes of the driver, and to prevent the adverse effects of the red exposure phenomenon of the infrared light supplementing lamp on the driver.

[0033] Generally, the internal heat dissipation structure is prone to performance degradation due to heating of internal electronic components during high load operation, and even causes thermal failure. The traditional module adopts a passive air gap heat conduction scheme, and there is an air medium layer between the heating element and the shell. Heat is conducted to the shell surface through low-efficiency convection for heat dissipation. The new structure realizes a breakthrough in heat management through the following innovations. For example, Figure 4 and Figure 5As shown, the application eliminates air gap thermal resistance by directly coupling the heat-generating IC 25 to the inner wall 26 of the shell through zero-gap heat conduction, and establishes a high-efficiency heat conduction path; the outer aluminum alloy heat dissipation fins 24 effectively expand the heat dissipation area, and synchronously integrate fluid dynamics guide grooves to utilize environmental airflow disturbance to improve convection efficiency; the heat dissipation fins 24 are integrally formed with the device rear cover 23 through die casting to form a sealed heat dissipation cavity, avoiding external dust and moisture intrusion. The multi-stage finned heat dissipation substrate integrally formed with the device rear cover 23, the heat-conductive medium filled between the camera module PCB and the substrate, and the heat dissipation substrate provided with the guide grooves form a passive airflow circulation path with the device shell air duct.

[0034] It should be noted that the internal configuration of the camera with decoding circuit, circuit board and electrical connection with external devices through network interface and / or BNC interface and power supply interface are well known in the art, and will not be described here. Red exposure phenomenon refers to the weak red light emitted by the lamp body that can be seen by the human eye when the infrared lamp is working. This is because the light emitted by the infrared lamp is not completely pure and invisible infrared, and a part of the light has a wavelength in the visible red light band range of the human eye. From the principle of optics, the infrared lamp emits light based on the electronic transition process of semiconductor materials. When the current passes through the chip of the infrared lamp, the electrons jump between different energy levels, thereby emitting photons. The emission spectrum of the infrared lamp is not a single wavelength, but has a certain bandwidth. Although the main energy is concentrated in the infrared band, a small amount of photons in the visible light red band in this spectrum range have high enough energy, and their wavelengths make them be perceived by the human eye, thus causing the red exposure phenomenon.

[0035] Although the preferred embodiments of the application have been described, those skilled in the art can make additional changes and modifications to the embodiments once they know the basic creative concept. Therefore, the appended claims are intended to include the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the application.

[0036] Finally, it should also be noted that in this document, relational terms such as first and second and the like can only be used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that these entities or operations exist in any such actual relationship or order. Moreover, the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or further includes elements inherent to such a process, method, article or terminal device. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article or terminal device including the element.
