Abstract

The invention provides an image measuring method and system that includes following steps: the workpiece is put on the image measuring machine; the present coordinate of the optical lens of the image measuring machine is obtained; the coordinate is processed by the accuracy compensation to get the compensated coordinate; the characteristic information is obtained by processing and calculating; the characteristic information is output. The shape and size of the workpiece can be measured by the invention, and it has high measuring efficiency, and full measuring function.

Description

【Technical field】 [0001] The invention relates to an image measurement system and method, in particular to an image measurement system and method for measuring the shape and size of a workpiece. 【Background technique】 [0002] Quality is one of the important factors for an enterprise to maintain its long-term development ability. How to ensure and improve product quality is an important part of enterprise activities. Before the mass production of products, the manufacturing plant needs to produce several samples for measurement to check whether there are quality problems, such as whether the size and shape of the workpiece are within the tolerance range. At present, most of this measurement method is done by human using measuring tools. , manual operation has large errors, low efficiency and difficult to guarantee accuracy. [0003] With the development and application of computer technology, measurement technology is no longer limited to manual operations, and computers ar...
