Abstract

In this paper, we study the optoelectronic functions of a 3D camera based on a laser rangefinder for an autonomous planetary rover. The main specifications to be satisfied are a range of 50 cm to 20 m with an accuracy of 1 cm or 1 percent and a continuous measurement rate of 0.1 ms. A critical analysis enables us to select two physical principles based on the measurement of the time taken for the propagation of light: pulsed and phase-shift rangefinding techniques. From the intrinsic properties of these both techniques, we study the influence of restrictive factors like the time of acquisition of a complete image and the comparison of the signal to noise ratio of these different kinds of devices.
