Problems solved by technology

[0002] With the development of photoelectric imaging sensors and image processing system platforms, the market has higher and higher requirements for camera resolution, especially for ADAS cameras, low-pixel cameras can no longer meet the needs of use and are gradually being eliminated.
However, due to the improvement of pixels and the increase of power consumption of the camera, or the change of the temperature of the working environment of the camera, the temperature drift of the camera is particularly obvious.
On the other hand, with the development trend of camera miniaturization, the accumulation of heat inside the camera will make the internal temperature become higher, which makes the problem of lens temperature drift more serious.
These factors will cause significant changes in the resolution of the camera, affecting the accuracy of the ADAS algorithm and even driving safety, and may even cause personal danger in severe cases

The camera comprises a lens (1), a lens seat (2) assembled with the lens (1), a circuit board (3) and an image sensor (4) connected with the circuit board (3), and further comprises a steel plate (5). The circuit board (3) is supported on the steel plate (5) and is fixedly connected with the lens seat (2) through the first glue (6), or the steel plate (5) is fixedly connected with the lens seat (2) through the second glue (7), and the circuit board (3) and / or the image sensor (4) are / is fixedly connected with the steel plate (5). The camera provided by the invention has a good temperature drift compensation function.

Description

Technical field [0001] The invention belongs to the technical field of vehicle imaging, and particularly relates to a camera. Background technique [0002] With the development of photoelectric imaging sensors and image processing system platforms, the market has higher and higher requirements for camera resolution. Especially for ADAS cameras, low-pixel cameras have been unable to meet the demand for use and are gradually eliminated. However, due to the increase in pixels and the increase in the power consumption of the camera, or the change in the temperature of the camera's working environment, the temperature drift of the camera is particularly obvious. On the other hand, with the development trend of miniaturization of the camera, the internal heat accumulation of the camera makes the internal temperature become higher, which makes the problem of lens temperature drift more serious. These factors have caused obvious changes in the resolution of the camera, affecting the acc...
