Method and apparatus for adjusting installation flatness of lens in real time

An apparatus for adjusting the installation flatness of a lens in real time, the apparatus comprising:

• a target;
• a processing system;
• and
• a display device,
• wherein the target is configured to present at least two groups of testing charts corresponding to different positions of a camera photosensitive surface,
• wherein the processing system is configured to:
• receive an image comprising the at least two groups of testing charts captured by the camera,
• pre-process the image comprising the at least two groups of testing charts to separate the at least two groups of testing charts from the image, the processing system being further configured to:
• perform filtering on the image to obtain testing chart regions in different directions:
• and
• perform image binarization on the testing chart regions to separate the at least two groups of testing charts from the image, and
• calculate a real-time resolution value associated with the camera photosensitive surface for each group of testing charts in real time based on each group of testing charts separated from the image, and
• wherein the display device is configured to:
• receive the real-time resolution value associated with the camera photosensitive surface for each group of testing charts from the processing system, and
• display the real-time resolution value for each group of testing charts, so that a user adjusts an installation angle of an optical axis of the lens relative to the camera photosensitive surface in real time based on the real-time resolution value associated with the camera photosensitive surface of the camera for each group of testing charts.
