Abstract

The embodiment of the present invention discloses a high-precision imaging system, method, image acquisition device and detection equipment. The imaging system includes: a super-telecentric lens and a first point light source; wherein the super-telecentric lens has a negative center, The spatial distance between the mirror point of the negative center relative to the first plane to be imaged and the center of the first point light source does not exceed a first error range, and the first error range is within 40 mm. The technical solution of the present invention effectively improves the imaging consistency through the integrated corresponding setting of the super-telecentric lens and the point light source, and can obtain high-precision and stable workpiece images.

Description

technical field [0001] The invention relates to the technical field of imaging equipment, in particular to a high-precision imaging system, method, image acquisition device and detection equipment. Background technique [0002] In the current field of workpiece inspection, the defect detection of small workpieces, especially fine parts, largely relies on the naked eye inspection of assembly line workers. In order to improve the detection efficiency, the existing technology attempts to introduce machine vision technology based on image recognition, and detect and find defects on the workpiece through intelligent recognition of the collected workpiece images. [0003] However, machine vision technology has faced many challenges for a long time. In particular, metal surface parts have high reflective properties, and it has been difficult to perform stable high-quality imaging for a long time. Machine vision technology relies heavily on the quality of captured images, which are...
