Title:
AUTOMATIC VISION TEST DEVICE FOR WORKPIECE WITH COMPLEX CURVED SURFACE
Document Type and Number:
Japanese Patent JP2022126587
Kind Code:
A
Abstract:
To provide an automatic vision test device for a workpiece with a complex curved surface.SOLUTION: A camera and a light source are provided in a test unit supporting frame. One camera and a plurality of light sources arranged in the camera form one test unit. The distance between the light sources and an object is at least five times as large as the field of vision of the camera. When an imaging work is performed using the same test unit, the light sources are sequentially emit light. The camera takes an image of the object every time the light sources emit light one time. One imaging by the camera requires one light source alone to emit light. The regions with the highest illuminance of the object of each light source in the same test unit do not overlap with each other.SELECTED DRAWING: Figure 2
