Non-contact image detector detection method

Abstract

A non-contact image detector detection method comprises the following steps: setting a scale in a visual scope of an image measuring instrument, using a crossbeam transmission system and a horizontaldriving mechanism to change the visual angle of the image measuring instrument with respect to a workpiece, and obtaining workpiece images of at least two visual angles; using computer software to determine a workpiece three dimensional structure on the basis of the workpiece images via gray scale conversion and characteristic collection, and comparing same with the scale so as to obtain the dimension information; forming a three dimensional model in the three dimensional processing software, and further using the three dimensional model to form engineering views of each plane of the workpiece. The detection method can fast provide the accurate workpiece three dimensional model, thus easily forming various engineering views; the method can directly form the three dimensional model withoutartificially setting output parameters.

Problems solved by technology

[0003] However, the existing non-contact image measuring instruments still have insufficient rigidity. After a period of application, each bearing mechanism deforms, thereby reducing the accuracy of image detection; The measuring instrument needs to be connected with the outside world through a transmission line to output data such as images, resulting in the need for a large number of connecting lines in the structure. The structural design of the imaging device is easy to cause damage to the line, and it is not conducive to the position adjustment of the image measuring instrument and the replacement of the lens. ; Moreover, the detected images cannot be converted into engineering drawings in a timely manner, often after a lot of processing, the process is time-consuming, and requires manual intervention settings
