This invention provides a standardized machine vision-based system for synchronously detecting the diameter and spacing of perforated holes in drainage boards, relating to the field of drainage board detection technology. It includes a standardized visual acquisition module, a composite adaptive optics illumination module, an anti-interference hole contour extraction module, a dynamic hole spacing boundary recognition module, a hole position anomaly recognition module, and a standardized database unit. The standardized visual acquisition module provides a standardized image foundation for subsequent detection. This invention constructs a standardized visual acquisition architecture, solving the shortcomings of existing visual acquisition modules, such as the lack of unified standards and large imaging deviations. Through standardized camera and light source configurations and a periodic calibration mechanism, combined with ambient light compensation, it ensures consistent imaging quality across different batches and devices, improving the universality of detection results. Simultaneously, it provides a standardized image foundation for subsequent detection algorithms, reducing algorithm adaptation difficulty and meeting the detection needs of industrial-scale production.

The present application relates to the field of optical imaging technology.The present application relates to an optical AI coding optical imaging system based on optics.The system comprises a mask plate adding unit, a blurred image unit, a phase parameter unit, an AI coding unit and a decoding recovery unit;the mask plate adding unit is used for obtaining a pupil specification, then a non-rotationally symmetric phase mask plate is added at the pupil according to the pupil specification, and the sensitivity of different parameter combinations to defocus aberration is simulated for the phase mask plate;by adding the non-rotationally symmetric phase mask plate at the pupil, combined with the non-focal point phase modulation plate to form a synergistic effect, the target can be imaged in a long dynamic range without zooming and focusing, meanwhile, the phase modulation depth and mask size of the phase mask plate are completely matched with the pupil specification, the non-focal point phase modulation plate adopts a non-rotationally symmetric phase distribution, and the two cooperate to strengthen the insensitivity of the system to the defocus of the image plane, so that the blurred modes of imaging at different defocus positions in a large focal depth range are consistent.
