摘要
图像测量方法具有非接触性、信息量丰富、动态范围大等一系列优点,成为易变形零件尺寸、零件孔心距等自动测量常用的手段。在此详细介绍基于CCD图像高精密微小零件尺寸检测系统,提出采用数字图像技术对微小零件尺寸实施非接触性测量法,主要由图像采集、二值化、边缘检测、软件设计等组成,从而获得被检测物体精确的参数值,并通过微小齿轮中心孔直径这一实例验证图像检测方法准确性和可行性。
With the rapid development of image processing technology,the image measurement method has the advantages of non-contact,rich information quantity,large dynamic range,etc,and becomes the common means to automatically measure the size of easy deformation parts,and hole center distance of parts. The CCD image based size detection system for high-precision miniature parts is introduced in detail. The non-contact measurement method to detect miniature part sizes by means of digital image technology is put forward. The precise parameter values of the detected object are obtained by image acquisition,binarization,edge detection and software design. The accuracy and feasibility of the image detection method were verified by an instance detecting the center hole diameter of a micro gear
