Problems solved by technology

[0002] At present, in order to solve the inaccuracy of manual adjustment in the detection industry and CCD measurement industry, it is necessary to repeatedly adjust the lighting of the light source and the focal length of the camera, which takes a long time and cannot be quantified. The present invention provides an automatic lighting and focusing structure. This structure can capture the surface of the object under test and judge its feature definition during work, and adjust the camera focal length and light source lighting after the system feedback, so as to realize the automatic lighting and focusing function without human participation

Abstract

The invention discloses an automatic lighting and focusing detection structure, comprising a holding frame and an image acquisition device and a light source device mounted on the holding frame, wherein the image acquisition device is used for imaging a detected object and acquiring an image. The light source device is configured to light the detected object to make the contour and the line of thedetected object clear. The automatic lighting and focusing detection structure further includes a motion control device and a main controller, wherein the motion control device is configured to adjust the focus of the image capturing device and achieve multi-angle lighting; the main controller is configured to determine whether the sharpness of the image satisfies a set sharpness value or a grayscale value, and control the operation of the motion control device and the light source adjustment of the light source device. The detection structure automatically captures a feature to be tested onthe detected object and determines the sharpness or grayscale value thereof, and uses system feedback to adjust the focal length of the camera and the lighting angle of the light source, has high focusing and lighting precision and fast adjusting speed, and saves time for focusing and lighting.
