Visual inspection device with function of effectively improving image resolution

Abstract

The invention relates to the technical field of visual inspection and discloses a visual inspection device with a function of effectively improving image resolution. The visual inspection device comprises a working platform, wherein a rack is arranged on the working platform; an arm is arranged on the rack; an image acquisition device is fixedly mounted at the vertical end of the arm; a camera shooting device comprises an image sensor; an image emitter is arranged on the image sensor and emits an image signal to an image acquisition card which is mounted in a slot of a computer host; a lens device is arranged at the bottom end of the camera shooting device; a first light source emitter is arranged on the camera shooting device; a first light source emitting tube is mounted on the first light source emitter; a cavity of a casing body of the image acquisition device is communicated with a hollow cavity of a dimmer; a shading coating is arranged on the inner side wall of the dimmer. According to the device, the problems of low detection efficiency and poor reliability of a detection result due to poor resolution of an acquired image during image acquisition by an existing visual inspection device are solved.

Description

technical field [0001] The invention relates to the technical field of visual detection, in particular to a visual detection device for effectively improving image clarity. Background technique [0002] Visual inspection is to use machines instead of human eyes for measurement and judgment. Visual inspection refers to converting the captured target into an image signal through machine vision products (that is, image capture device, divided into CMOS and CCD), and sending it to a dedicated image processing system. Digitized 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. Is a valuable mechanism for production, assembly or packaging. It is invaluable in its ability to detect defects and prevent defective products from being shipped to consumers. [0003] However, when the existing visual inspection device collec...
