Problems solved by technology
In the actual design and production process, the sensor with the focal plane is often welded on the printed board, and the printed board is installed on the shell structure. Due to the limitation of the process, the focal plane is often not perpendicular to the optical axis accurately, resulting in When the camera is imaging, some areas of the image are in focus and some areas are out of focus
[0003] In order to solve this problem, currently in the production process, the installer needs to adjust the position of the adjustment point on the sensor printed board so that the photosensitive surface of the sensor is perpendicular to the optical axis. The requirements are also high, which greatly affects the production efficiency

The invention provides a camera focal plane automatic adjustment and calibration system, which comprises an adjustment and calibration pattern plate and a focusing plate for adjusting and calibratinga camera focal plane, an imaging unit used for imaging the adjustment pattern plate and outputting an imaged image to the definition evaluation unit; a definition evaluation unit used for receiving animaging image of the imaging unit, dividing the image into N areas and calculating definition evaluation values corresponding to the N areas; an electric adjustment control unit used for receiving the definition evaluation value of the definition evaluation unit, processing and analyzing the definition evaluation value and outputting a regulation and control instruction; and a plurality of electric adjusting points used for receiving an adjusting and controlling instruction of the electric adjusting control unit and adjusting the imaging unit. The automatic adjustment and calibration system is simple in structure, automatic operation of camera focal plane adjustment and calibration is achieved, and the camera focal plane adjustment and calibration efficiency and the camera production efficiency are greatly improved.
Description
【Technical field】 [0001] The invention relates to the technical field of camera focal plane adjustment, in particular to a camera focal plane automatic adjustment system and method. 【Background technique】 [0002] In the production process of the camera, the adjustment of the focal plane is an essential key link. The ideal location of the focal plane should be at the focal point of the lens, perpendicular to the optical axis. In the actual design and production process, the sensor with the focal plane is often welded on the printed board, and the printed board is installed on the shell structure. Due to the limitation of the process, the focal plane is often not perpendicular to the optical axis accurately, resulting in When the camera is imaging, some areas of the image are in focus and some areas are out of focus. [0003] In order to solve this problem, currently in the production process, the installer needs to adjust the position of the adjustment point on the sensor ...
