Acquisition of range images
First Claim
Patent Images
1. Method for generating range images comprising the steps of, generating a plurality of partial range images by means of transmitting short light pulses and receiving reflections arriving within particular periods of time only, including, producing each of said partial images with a different gray value;
- andcomposing a composite range image from said partial images by combining different gray values of the different partial images.

Abstract
Short light pulses are emitted and images of the reflection from objects are received; the receiving is timed and synchronized to obtain partial images corresponding to reflection from particular ranges; the partial images are then combined in a composite range image.
