Abstract [en]

Triangulation technique is one of the most commonly techniques used in three dimensional measurements. Depth reconstruction accuracy is a direct impact of the quantization process and this is related to the number of pixels of the sensor. Dithering technique (DT) benefits from relative fine movement between object and sensor to reduce the quantization error. This paper describes the theory of the DT and establishes a mathematical model. To evaluate if DT technique can improve the accuracy in real world, a control rig was designed and built, following which experiments were performed. The results showed that considerable improvement can be achieved in measurement accuracy.
