Description

Technical Field

[0001] The present invention belongs to the technical field of computer vision related to automatic adjustment of camera posture, and in particular relates to an automatic control and adjustment device for camera posture. Background Art

[0002] A camera is a device that uses optical imaging and photoelectric conversion technology to capture and record images. It contains the following main components:

[0003] Lens: The camera lens is composed of a group of lenses, and its function is to focus light onto the photosensitive element. When light passes through the lens, the lens refracts and focuses the light to form a clear image;

[0004] Shutter: The shutter is a device in the camera that controls the length of time that light enters the photosensitive element. When the photographer presses the shutter button, the shutter will open for a certain period of time, allowing light to pass through the lens to the photosensitive element. The speed of the shutter will affect the exposure time, thereby affecting the brightness of the photo;

[0005] Photosensitive element: The photosensitive element is one of the most important parts of the camera, which is responsible for converting light into electrical signals. Modern digital cameras usually use CCD (charge-coupled device) or CMOS (complementary metal oxide semiconductor) as a photosensitive element. When light shines on the photosensitive element, each pixel will generate a corresponding charge or voltage change according to the intensity of the light, thereby recording the information of the light;

[0006] Image processor: The light information recorded by the photosensitive element will be converted into digital signals and undergo a series of image processing, such as color correction, denoising, sharpening, etc., to generate the final digital image file.

[0007] To sum up, the working principle of a camera is to focus light through the lens, control the time when light enters the photosensitive element through the shutter, and then the photosensitive element converts the light into an electrical signal and records it. Finally, image processing is performed to generate a visible image. Therefore, cameras are used to record life and beautiful things and are therefore deeply loved by people.

[0008] With the continuous development of science and technology, the functions of current smart mobile devices are diversified, and the cameras in smart mobile devices are becoming more and more functional and comprehensive. For example, the patent office has published an application number of 202410399660.5, which is a method and system for automatic adjustment of camera posture, which includes: using deep learning algorithms and traditional machine learning algorithms to obtain matching points between camera-taken pictures and reference pictures, and filtering out erroneous matching points; obtaining camera intrinsic parameters through camera calibration, and using epipolar geometry and triangulation to obtain the three-dimensional coordinates of matching points; using a direct linear transformation algorithm to obtain the camera posture, thereby adjusting the camera posture; finally, using the identifier on the picture to adjust the error so that the error is within a controllable range. The present invention adopts a camera adaptive adjustment algorithm, which is simple to implement, not easily affected by the external environment, has high execution efficiency, and can greatly improve the accuracy of camera calibration. However, this method has the following problems: 1. The overall algorithm is relatively complex; 2. The posture adjustment is mainly aimed at the camera being often affected by complex environmental factors and causing jitter, such as geological vibrations, strong winds and other special situations, and then the captured images are mismatched in the matching of the same-name points in consecutive frames, resulting in errors in the final calculation. However, the above system does not automatically correct the standing position of a person. Therefore, when the standing position of a person deviates from the display frame, it cannot be automatically corrected and needs to be adjusted manually, resulting in inconvenient operation. In addition, it is impossible to automatically adjust the light according to the ambient brightness and automatically adjust the camera angle. Summary of the invention

[0009] The purpose of the present invention is to provide an automatic control and adjustment device for a camera posture, which solves the problem that the existing camera posture adjustment does not automatically correct the person's standing position.
