Technical Field

[0001] The utility model relates to the technical field of automatic driving, in particular to a camera assembly with servo. Background Art

[0002] With the rapid development of my country's automobile industry, intelligence, electrification and networking have become new trends in the industry's development. Unmanned driving technology has also made great progress, especially the comprehensive application of various sensors and algorithms. It is necessary to realize the vehicle's environmental perception and precise control. This requires real-time and accurate data on the vehicle's operating status and its surrounding environment, and there are also great requirements for obtaining images of the vehicle's surrounding environment.

[0003] The realization of driverless technology mainly relies on the comprehensive application of multiple sensors and algorithms, including but not limited to cameras, radar, lidar, ultrasonic sensors, etc. Driverless technology requires images of the vehicle's surroundings to assist driving, but the field of view of traditional fixed cameras is limited, resulting in blind spots for a single camera, so multiple cameras are required to cover all directions around the vehicle, increasing costs. In addition, the image quality of fixed cameras will be weakened under different lighting conditions, weather conditions or road types, which may affect the accuracy of information.

[0005] A camera, used to collect images;

[0006] The visible light and infrared movement can process the images collected by the camera and transmit them to the host computer or the car for auxiliary driving. It can transmit the control command information to the servo control board through the 422 serial port to control the steering of the camera.

[0007] The encoder is used to provide two-way angle information of the camera's pitch and yaw to facilitate servo control;

[0008] The gyroscope is used to provide two-way velocity information of the pitch and yaw of the camera movement to facilitate servo control;

[0009] The motor is used to receive servo control commands to drive the camera to move, which can increase the camera's field of view and reduce blind spots;

[0010] The servo control board is used to receive commands transmitted from the car or movement, control the position of the camera, reduce blind spots, and can also be set to stable mode to offset the impact of shaking on camera imaging.

[0011] Furthermore, the camera is a dual-light zoom camera.

[0012] Furthermore, the servo control board adopts the domestic chip GD32 as the main control chip.

[0013] Furthermore, the visible light and infrared movement has a matching recognition program, which can recognize and mark cars and pedestrians in the field of view and can track moving objects.

[0014] Furthermore, the rotation of the camera is achieved through a connected direction axis.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model proposes a camera assembly with servo, which can rotate 120 degrees horizontally and vertically, and 90 degrees in pitch, and can scan and collect information in all directions, reducing the requirement for the number of cameras, being able to adapt to more occasions with poor conditions, and providing more information to assist safe driving.
