In the field of work, cameras are widely used in video conferencing, telemedicine, and military management. , traffic management, real-time monitoring and file management. In actual use, image information is obtained through photography and stored as digital information available for use. Images or pictures can be transmitted, browsed and retrieved through various channels such as the network or smart devices, which brings great benefits to people's lives. Convenience and enrich people's lives.

When a camera is used to shoot an object, the light reflected on the object is collected by the lens of the camera to focus on the light-receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electrical energy through the camera device, that is, Got the "video signal". When the photoelectric signal is very weak, it needs to be amplified by the pre-playing circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or sent to a monitor. displayed above.

At present, monocular cameras are commonly used, but monocular cameras have an irreconcilable contradiction in the range and distance of ranging, that is, the wider the camera's viewing angle, the shorter the length of the precise distance that can be detected, and the greater the viewing angle. Narrow, the longer the detected distance, in order to solve the problem of the shooting range and test distance of the monocular camera, the shooting range is usually expanded by increasing the number of cameras, and the use of multi-eye cameras will increase the cost of the user. Based on this, a camera device, a camera, and an unmanned aerial vehicle provided by the embodiments of the present invention can alleviate the above technical problems.

Finally, the digital image signal is sent to a digital processor for processing, and then passed through The I/O interface (Input/Output Interface, input/output device interface) on the soft board is transmitted to the terminal, cloud processor or screen for use.

In specific implementation, the above-mentioned camera module is usually a camera module arranged on a camera. When the camera module includes one camera unit, the camera can be called a monocular camera. When the camera module includes two camera units , the camera may also be called a binocular camera. Further, the camera may further include a larger number of camera units to meet camera requirements, which may be set according to actual conditions, which is not limited in this embodiment of the present invention.

Further, the above-mentioned camera unit is equivalent to the camera in the camera. Usually, the structure of the camera is composed of multiple lenses. Generally, the lenses can be divided into plastic lenses and glass lenses.

For ease of understanding, FIG. 1 only shows two camera units, and a reflective prism is installed on the incident light side of the lens of one of the camera units. Preferably, the reflective prism is a Lehman prism. In actual use, it can be By adjusting the position of the Lehman prism, the light entry point of the incident light of the camera unit when collecting image information is changed, so as to achieve the purpose of increasing the shooting range.
