Abstract: The reflection characteristics of the measured objects and the obtrusive light of the environment will have strong impacts on the accuracy of laser triangulation displacement measurement. In order to reduce the impact, a new imaging parameters adaptive control methods was proposed. The imaging parameters of an image sensor were described and the effect of these parameters on the accuracy of measurement was analyzed. Then an idea of improving the accuracy was put forward by parameters adjustment. The experimental results show that this method can adaptively adjust the parameters based on the environment, effectively reduce the environment inteuerence and ultimately improve the displacement measurement accuracy.
