| Abstract: | A way of detecting the structured light strip center line based on genetic algorithm, which is capable of optimizing the selection of image threshold value and accurately segmenting the light strip from the laser image, is proposed to improve the accuracy of the structured light 3D information acquisition system. The laser center line is further detected from the laser stripe through data processing and using alterable detection templates. Experimental results show that, with the adaptive rate of crossover and aberrance properly selected for genetic algorithm, the structured light strip center line can be accurately acquired to satisfy the system accuracy requirement. |
