Image measuring board control system and method

Abstract

The invention discloses an image measuring board control system, which comprises an establishment module, an acquisition module, a computation module and a driver module, wherein the establishment module is used for establishing a plane coordinate system for a workpiece to be tested, namely a first coordinate system, in a computer-aided design (CAD) chart file for the workpiece to be tested, and establishing a plane coordinate system for the workpiece to be tested, namely a second coordinate system, on a board working surface of an image measuring board; the acquisition module is used for acquiring a coordinate valve of a tested element characteristic of the workpiece to the tested in the first coordinate system and acquiring position information of a board lens of the image measuring board relative to the second coordinate system; the computation module is used for computing the moving direction and displacement required by the board lens according to the coordinate value of the tested element characteristic in the first coordinate system and the position information of the board lens; and the driver module is used for sending a driving signal to a driving unit according to the moving direction and the displacement required by the board lens so as to control the board lens to move to the position of the tested element characteristic. The invention also provides an image measuring board control method.

Description

technical field [0001] The invention relates to an image measuring machine control system and method. Background technique [0002] The image measurement method is currently the most widely used measurement method in the field of precision measurement. This method not only has high precision, but also has a fast measurement speed. Image measurement is mainly used to measure the dimensional error and shape error of workpieces (parts or components), and plays an important role in ensuring product quality. [0003] Generally speaking, the image measurement method is to capture images of different parts of the workpiece to be measured by moving the machine lens (such as a CCD lens) of the image measurement machine, so as to perform image measurement on the workpiece to be measured. In the traditional image measurement method, the machine lens is moved by manually operating the handle of the image measurement device, so that the machine lens reaches the position to be measured. ...

Problems solved by technology

However, it is difficult to operate the machine lens in place at one time by manual operation, which makes the positioning speed of the machine lens slow and the accuracy is not high
