[0002] With the development of the automobile industry, the configuration rate of cars with panoramic images and reversing images is getting higher and higher, and their uses are becoming more and more extensive. Many new functions have gradually been derived from the simple reversing assistance system, such as pedestrian recognition, blind spot monitoring, lane departure and other functions. When the on-board camera is generally installed in the front, rear, left and right positions of the vehicle, it can improve driving safety, protect the safety of passengers and vehicles, and improve traffic safety. The camera installed at the front of the vehicle can monitor the road conditions ahead and provide functions such as front obstacle warning and adaptive cruise control; the camera installed at the rear of the vehicle can monitor the traffic conditions behind and provide functions such as reversing images; the camera installed on the side of the vehicle can monitor the side traffic conditions and provide functions such as side parking assistance. However, in daily applications, car owners often find that the camera lens is affected by the shape and cannot protrude too much from the outer surface. The field of view is limited and it cannot provide all-round images, resulting in false alarms and missed alarms. Summary of the invention

[0003] The purpose of the present invention is to provide a vehicle-mounted camera device, a control method thereof and a vehicle. By applying the control method of the vehicle-mounted camera device, during the use of the vehicle, the real-time captured image data is compared with the data in the preset scene image database to determine whether to turn on or off the automatic telescopic rotation function of the camera, and the camera is controlled to automatically extend and rotate in all directions. This solves the problem that the existing car camera cannot protrude too much from the surface due to the limitation of the body shape and the field of view is limited. The shooting range of the camera is increased, a panoramic fusion image of the use scene is provided, and a scientific reference basis is provided for the control system warning and alarm.

[0006] The vehicle-mounted camera device of the present invention uses a worm gear and ball screw transmission structure, and cooperates with an electric universal joint to realize that the camera hidden and installed at the two ends of the front and rear bumpers or the front and rear corners of the body decorative panel can be freely extended and retracted in the installation hole, and rotate in all directions after being extended out of the vehicle, which solves the problem that the traditional vehicle-mounted camera cannot protrude too much from the body due to the influence of the body shape, resulting in a narrow shooting field of view, blind spots, image omissions, and wrong shots. The control method of the vehicle-mounted camera device of the present invention is to collect scene image data in advance as samples to form a preset scene image database, and the scene image data includes image data of various scenes such as high-speed driving scenes, complex road conditions scenes, ground parking lots, and underground garages. After the vehicle is started, the camera is turned on for real-time shooting, and the image data taken is sent to the body control module, which is then sent to the electronic control unit. The electronic control unit compares the received image data with the corresponding scene image data in the preset scene image database. When the comparison result is higher than the threshold value of the scene similarity with the scene of turning on the telescopic rotation function, the threshold range is 60%-90%, and the preferred value of the present invention is 80%, the electronic control unit sends the camera telescopic rotation function turning on instruction to the body control module, and after receiving the instruction, the body control module sends the telescopic function turning on instruction to the controller of the vehicle-mounted camera device to the motor. The housing of the vehicle-mounted camera device is a rectangular accommodating cavity, the driving mechanism is accommodated and connected in the housing, and the camera is connected to the driving mechanism by transmission.
