Abstract
A method and apparatus for generating three-dimensional range images of spatial objects, wherein a short-time illumination of the object is performed, for instance using laser diodes. An image sensor is used that has a high light sensitivity, pixel resolution and can be read out randomly, this sensor also having an integration time that can be adjusted for each pixel. By evaluating the backscattered laser pulses in two integration windows with different integration times and by averaging over several laser pulses, three-dimensional range images can be picked up with a high reliability in, for example, 5 ms at the most.
