Abstract

In this paper a design of a new triangulation angular scan LED array-based range imaging sensor is described. The essential advantages of the scanner are construction without any moving parts, small size, good stability, and low cost. The operation principle of the sensor is presented and theoretical background for the sensor design is discussed, including such problems as simulation of power budget and modelling of geometry of the sensor. Based on the theoretical analysis, a sensor design is described, including such issues as modular approach, placement of the transmitter and receiver modules, and software for the sensor operation. Results of the sensor performance tests are briefly discussed. The presented sensor is considered as a new device for performing inexpensive and fast range scanning for many robotic and shape measurement applications.
