Research on Liquid Zoom Structured Light 3D Measurement System
To solve the limitations of the traditional structured light method applied to the three-dimensional detection of underground space,the design principle and application method of liquid zoom structured light three-dimensional measurement system are innovatively proposed by combining the liquid lens focusing technology with the structured light self-scanning measurement method.Firstly,the structural design model of the liquid zoom structured light three-dimensional measurement system is proposed,and the working mechanism of the system is analyzed with theoretical derivation.Then,the corresponding parameter calibration methods are given for the zoom imaging module and the structured light projection module in the system,respectively.Finally,the test platform of the liquid zoom structured light three-dimensional measurement system is built to realize the accurate calibration of the system parameters,and the experiments are designed to test the system performance.The test results show that the system can flexibly switch the field of view under the condition of no-moving components,and can realize the three-dimensional measurement of the target under different scales of imaging field of view;measurement accuracy is affected by the combination of optical aberration and imaging focal length.The research can provide a new idea for the high-performance development of three-dimensional vision system for underground operation robots.
