Rotatable multi-angle visual inspection device and method

Abstract

The invention discloses a rotatable multi-angle visual inspection device and method. The inspection device comprises a rack, and a camera support frame, a horizontal displacement mechanism and wire gauges are arranged on the upper portion of the rack; a camera fixing block is arranged on the camera support frame, and used for fixing a camera, and a ring light is arranged around the camera; the wire gauges are arranged on the two side edges of the rack, support sliding blocks sliding along the wire gauges are arranged on the wire gauges, a bottom plate is arranged on the upper portions of the support sliding blocks, and a second stepping motor, an electric control module and a rotating platform are arranged on the bottom plate; a semicircular light is arranged around the rotating platform,and strip-shaped lights are arranged on the two sides of the semicircular light; the second stepping motor controls the rotating platform to rotate. The device is simple in structure, the stepping motor controls the rotating platform to rotate stably, products can be shot in multiple angles, and then the multi-angle machine visual inspection is achieved.

Description

technical field [0001] The invention relates to the field of machine vision detection, in particular to a rotatable multi-angle visual detection device and a detection method thereof. Background technique [0002] Machine vision is to use machines instead of human eyes for measurement and judgment. Through machine vision products (image capture devices), the captured objects are converted into image signals and sent to a dedicated image processing system. According to information such as pixel distribution, brightness, and color, Transformed into digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. [0003] The advantage of the machine vision system is to improve the flexibility and automation of production. In some dangerous working environments that are not suitable for manual work or where artificial visio...

Problems solved by technology

[0004] However, most of the current machine vision systems can only take pictures of products at one angle, and the detection of product defects is not accurate enough.

However, the structure of the machine vision system that can realize multi-angle shooting is relatively complicated, which is not conducive to large-scale promotion and use.
