Paper Abstract

We present new developments in optical 3d sensors using pico DLP as well as DSP technology. We use enhanced, high-powered pico DLP projection units and compact processing hardware to create likewise compact, light-weight measuring heads, which can perform the acquisition as well as the evaluation of 3D data without external computing power. Moreover, their drastically reduced cost and their networking ability also allows for an economical combination of a multitude of individual sensors into complex configurations. The entire form even of large and complex shapes can hereby be scanned in a very short time. New calibration strategies, integrating all individual sensor coordinate systems into a single, calibrated, global one, lead to an immediate combination of all sensor data into a single, complete point cloud. We show the principle and actual realization of sensors, calibration strategies and procedures, and examples of first realized multi-sensor measuring systems utilizing this new technology.
