Study on measurement accuracy of stereo visual sensor based on experimental design

The impact of stereo visual sensor parameters on the measurement accuracy of the sensor is studied based on experimental design. Using a mathematical model of stereo vision, errors caused by stereo visual sensor parameters are analyzed. Based on this, main parameters are identified and used in experimental design. In order to find the optimized combination of the parameters, optimum regression design method is used. Eleven primary experiments with different combinations of parameters are designed and conducted. According to the experiment results, a regressive equation is established. By resolving it, the optimized combination of the parameters is got.
