[0030] See also Figure 3 In this embodiment, the intelligent vehicle video terminal 1 includes a vehicle video server, which is equipped with multiple network interfaces. The vehicle video server is equipped with multiple input interfaces and output interfaces. It is the core component of the vehicle video terminal and is responsible for collecting audio and video signals in the car and compressing them into digital streams for transmission and storage. The input interface and output interface are used to connect to the auxiliary display screen 2 and the intelligent reversing camera 3.

[0031] It should be noted that, collecting audio and video signals: the vehicle-mounted video server collects audio and video signals in the vehicle through an external camera.

[0032] The actual operation of the vehicle video server includes the following:

[0033] Compressed digital stream: The collected audio and video signals are compressed into digital streams by the on-board video server for transmission and storage.

[0034] Transmit digital stream: The compressed digital stream is transmitted to the user monitoring center or remote monitoring management center through wireless networks such as CDMA2000, 3G, 4G, etc. This transmission method can realize remote monitoring and emergency command.

[0035] Display and storage: At the monitoring center or management center, the received digital stream can be decoded and displayed on the monitor or computer screen, and can also be stored in the server or storage device for subsequent viewing and analysis.

[0036] Additional functions: According to the configuration of the vehicle video terminal, other functions can also be realized, such as emergency alarm, speeding alarm, fatigue driving alarm, etc. These functions are usually realized by linkage with the vehicle's driving recorder, GPS positioning system and other equipment.

The control unit is usually located at the rear or inside of the vehicle, near the wheel housing. Its main tasks include providing power supply voltage to the camera, correcting the wide-angle image of the camera, inserting static and dynamic auxiliary lines into the image, etc.

[0038] The truck box docking guidance system in the prior art is turned on, and the intelligent reversing camera 3 is initialized; the images of the carriage and the hook are captured in real time by the intelligent reversing camera 3, and displayed on the display unit, that is, the auxiliary display screen 2; the on-board video server inside the intelligent on-board video terminal 1 is used for image preprocessing. The algorithm first receives the real-time image captured by the camera and performs preprocessing operations, such as denoising, contrast enhancement, etc., to improve the image quality and facilitate subsequent feature extraction and recognition. The intelligent reversing camera 3 and the ranging sensor screen are used to measure the distance, angle, relative position and other parameters between the carriage and the hook; position measurement and calculation: the distance, angle and relative position and other parameters between the carriage and the hook are measured by the vehicle docking area mark, and the optimal docking position of the carriage and the hook is calculated in combination with the image recognition result. This usually involves coordinate conversion and position calculation in three-dimensional space in the prior art. The intelligent vehicle video terminal 1 calculates the docking position of the carriage and the hook according to the data transmitted by the camera, and generates guide lines or marks. In the preprocessed image, the algorithm extracts the key features of the carriage and the hook, such as edges, corners, etc., and determines the position and direction of the carriage and the hook in the image through feature matching and recognition algorithms. The guide lines or marks are superimposed on the real-time image, and visual feedback is provided to the driver through the display unit, that is, the auxiliary display screen 2; docking path planning: according to the calculated optimal docking position, the algorithm plans a suitable docking path. Path planning needs to consider factors such as the vehicle's driving speed, steering angle, and possible obstacles to ensure the smoothness and safety of the docking process. According to the distance and angle changes between the carriage and the hook, the control unit issues sound prompts of different intensities to provide auditory feedback to the driver; the driver adjusts the vehicle position according to the visual and auditory feedback so that the carriage gradually approaches the hook; vehicle control: the algorithm converts the docking path into a vehicle control command, which is sent to the vehicle's actuator, such as the steering system, the braking system, etc., through the control unit. The vehicle makes corresponding adjustments according to the control command to achieve accurate docking with the hook. When the carriage is successfully docked with the hook, the system issues a confirmation prompt and automatically records the docking data. The above system and algorithm both adopt solutions that can be obtained in the prior art and will not be elaborated here.

[0039] Working principle: by installing the intelligent vehicle video terminal 1 in the truck, installing the auxiliary display screen 2 in the area inside the cab that is easily visible to the driver, and installing the intelligent reversing camera 3 in a position that can fully capture the image of the cargo box and the hook arm of the hook, when it is needed, the intelligent vehicle video terminal 1 and the intelligent reversing camera 3 are powered on and started, the intelligent reversing camera 3 is used to capture the position of the cargo box and the hook arm, and the ranging sensor is used to measure real-time data. The driver can adjust the position of the hook arm according to the time situation so that it can be accurately docked to play the role of auxiliary connection.
