Embodiment Construction

[0054] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] The embodiment of the present invention provides a visual detection method, which can convert different detection surfaces at a certain angle to the current shooting surface of the camera device, and only need to shoot the current shooting surface to realize simultaneous detection of detection surfaces at different angles. Inspection greatly reduces the process in the visual inspection process, saves th...

Abstract

The invention provides a method and system for visual detection. The method comprises the steps that a first detection face of a to-be-detected object is moved to a current shooting face of a photographic device; a second detection face of the to-be-detected object is reflected by a reflection device, and an image corresponding to the second detection face is converted to the current shooting face; an image on the current shooting face is collected; and the collected image is detected and analyzed, so an analysis result is obtained. According to the method and system for visual detection provided by the invention, different detection faces at certain angles can be converted by the reflection device to the current shooting face of the photographic device; and through shooting of the currentshooting face, the detection faces at the different angles can be detected at the same. Therefore, processes in the visual detection can be greatly reduced; time and material resources needed by thedetection can be saved; and efficiency of the visual detection can be increased.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a visual inspection method and system. Background technique [0002] In the process of process chemical industry, many processes require visual inspection, and in the process of visual inspection, in many cases, it is necessary to inspect many sides of a workpiece. If there is only one camera at present, it is necessary to change the position of the workpiece to detect different surfaces, or to change the position of the camera to detect different surfaces, which requires multiple processes and multiple shots, which increases the The detection process leads to increased detection time and reduced efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a visual inspection method and system to solve the problems of long detection time and low efficiency caused by multiple processes and multiple photographs of the detection surf...
