Description

Technical Field

[0001] The invention relates to an automatic compensation adjustment algorithm for measuring the offset of the upper and lower surfaces of a lithium battery coating, and is applicable to the field of intelligent surface detection. Background Art

[0002] The intelligent surface inspection system based on machine vision includes technical contents such as camera imaging and image detection. However, during the camera imaging process, the long-term vibration of the production line conveyor belt often causes the relative position of the production line conveyor belt and the camera to shift, which in turn causes calculation errors after the pixel size changes, resulting in errors in the actual results.

[0003] At present, the mainstream solution to the above errors is to manually adjust the compensation value to make the final result close to the ideal result. However, the existing mainstream solution requires professional engineers to make adjustments after the problem occurs, which affects the operation of the production line. Whether the adjusted value is reasonable also depends on the experience of the engineer. It is also difficult to assess how long it will take for the error to reappear after the adjustment. Failure to make adjustments in time will affect the production of the factory production line and reduce production capacity. Summary of the invention
