Abstract

A fuzzy self-adaptive adjustment method for light strip image imaging parameters, comprising the steps of: a) firstly, calling fuzzy inference system editor Fuzzy, and then calling evalfis for defuzzification to obtain the calculation result; b) completing the operation according to the provided COM interface Interact with data in other programming languages, perform data processing, and return processing results; c) Call the dynamic link library of the camera API through the USB2.0 interface to realize image acquisition, camera initialization, and acquisition parameter settings.

Description

technical field [0001] This patent relates to the adaptive adjustment of light strip image imaging parameters in three-dimensional visual measurement of line structured light, and belongs to the field of fuzzy control and image quality evaluation. Background technique [0002] With the development of digital technology and charge-coupled devices, the three-dimensional visual measurement technology based on line structured light has been widely used in reverse engineering, industrial inspection, cultural relics protection and other fields due to its advantages of high precision, strong real-time performance, active control, and simple structure. It has been widely used and has become an important branch of optical non-contact measurement. According to the working principle of laser triangulation, the line-structured light plane projected by the laser intersects the surface of the measured object, and the intersecting line is captured by the image sensor to form a two-dimensio...
