DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-Figure 2 A vehicle warning system based on image recognition includes a mounting base 1 and a shell 2 fixedly connected to the bottom end of the mounting base 1, a mounting panel 3 is slidably connected to one end of the inner wall of the shell 2, and a recognition camera 4 and a projection light 5 are fixedly installed on one end of the mounting panel 3. An adjustment component 6 is arranged inside the shell 2, and the adjustment component 6 can adjust the positions of the recognition camera 4 and the projection light 5 according to the usage to protect them. A processor 7 is fixedly arranged at one end of the adjustment component 6, and the adjustment component 6 is fixedly connected to the mounting panel 3 through a plurality of connecting rods 8, and a power supply 9 is fixedly connected to the inner wall of the shell 2.

[0024] A protective baffle 31 is fixedly connected to the bottom of one end of the mounting panel 3 . The protective baffle 31 can block the debris splashed from the bottom of the vehicle to prevent it from causing pollution and damage to the identification camera 4 and the projection light 5 .

[0025] The recognition camera 4 is a binocular camera. The recognition camera 4 and the projection light 5 are both electrically connected to the processor 7. The binocular ranging is mainly based on the parallax principle, that is, by comparing the images taken by the left and right cameras, the distance between the target object and the camera is calculated. The farther an object is from the camera, the smaller its displacement in the left and right images, and vice versa. By measuring this displacement, the distance between the object and the camera can be calculated.

[0026] In this embodiment: the device is installed on the bottom of the rear of the vehicle through the mounting base 1. When in use, the device monitors the rear vehicle in real time through the identification camera 4. The identification camera 4 is a binocular camera. Based on image recognition, the identified image data is transmitted to the processor 7 for processing using the binocular ranging method, and the distance between the rear vehicle and the identification camera 4 is calculated. When it is detected that the distance to the rear vehicle is reduced too quickly or the following distance of the rear vehicle is detected to be too close, an early warning is issued and the rear vehicle is reminded by alternately flashing the projection light 5. When driving at night, the projection light 5 can also project a safe following interval line on the ground, thereby achieving a better early warning effect, so that the driver has enough time to react and operate.

[0027] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3-Figure 5 The adjustment component 6 includes a fixed plate 61 fixedly connected to the side wall of the inner cavity of the shell 2 and a movable plate 62 slidably connected to the side wall of the inner cavity of the shell 2, and the fixed plate 61 and the movable plate 62 are elastically connected by a plurality of springs 63, and electromagnets 64 are fixedly connected to the adjacent side walls of the fixed plate 61 and the movable plate 62, and a plurality of sealing plates 65 are fixedly connected to the side wall of the movable plate 62, each sealing plate 65 is slidably connected to the side wall of the fixed plate 61, and a plurality of air holes 651 are opened on the side wall of each sealing plate 65.

[0028] One end of each connecting rod 8 is fixedly connected to the movable plate 62 , and the two electromagnets 64 are electrically connected to the processor 7 , and the two electromagnets 64 have the same polarity after being energized.

[0029] A plurality of heat dissipation ducts 21 are provided on the end face of the shell 2, and a plurality of heat dissipation holes 22 connected to the interior of the shell 2 are provided on the inner cavity side wall of each heat dissipation duct 21. During use, the air holes 651 on the sealing plate 65 are aligned one by one with the heat dissipation holes 22 to ensure gas circulation. After use, as the electromagnet 64 is powered off, the sealing plate 65 slides toward the fixed plate 61 driven by the movable plate 62, and finally the heat dissipation holes 22 are misaligned with the air holes 651 to achieve a blocking effect.

[0030] In this embodiment: the device generates a certain amount of heat during use, and it is installed at the rear of the vehicle. The exhaust gas of the vehicle will make the temperature of the rear higher. By opening a heat dissipation duct 21 in the same direction as the vehicle's travel direction on the end face of the shell 2, the external air can quickly flow through the heat dissipation duct 21 of the shell 2 during the vehicle's driving, thereby reducing the pressure in the heat dissipation duct 21. The heat generated by the components inside the shell 2 enters the heat dissipation duct 21 through the heat dissipation holes 22 and is taken out, thereby achieving a good heat dissipation effect on the device; when the vehicle is parked and turned off, the adjustment component 6 The two electromagnets 64 are powered off. Since the polarities of the adjacent ends of the two electromagnets 64 are the same, the mutually repelling force disappears after the power is turned off. At this time, under the elastic force of the spring 63, the movable plate 62 slides toward the fixed plate 61, and the installation panel 3 is received into the inner cavity of the shell 2 through the connecting rod 8, so as to protect the recognition camera 4 and the projection light 5 installed on the installation panel 3 and prevent them from being damaged by external debris. At the same time, the sealing plate 65 slides toward the fixed plate 61 driven by the movable plate 62, and finally the heat dissipation hole 22 is misaligned with the air vent 651, so as to achieve a blocking effect and prevent water from entering the interior.

[0031] Working principle: the recognition camera 4 is a binocular camera, which uses the binocular ranging method to transmit the recognized image data to the processor 7 for processing, and calculates the distance between the rear vehicle and the recognition camera 4, so as to monitor the rear vehicle in real time; when it is detected that the distance to the rear vehicle is reduced too quickly or the following distance of the rear vehicle is detected to be too close, an early warning is issued and the rear vehicle is reminded by the alternate flashing of the projection light 5; when driving at night, a safe following interval line is projected on the ground by the projection light 5; during the driving of the vehicle, the external air is driven to flow rapidly through the heat dissipation duct 21 of the shell 2. Since the greater the gas flow rate, the smaller the pressure, the pressure in the heat dissipation duct 21 is reduced, and the hot air inside the shell 2 enters the heat dissipation duct 21 through the heat dissipation holes 22 and is taken out, thereby achieving the effect of heat dissipation and cooling the inside of the shell 2.
