Abstract
PURPOSE:To obtain a distance image in a necessary area with high resolutions with the acquisition of a rough absolute distance as such, by performing an intensity modulation by a higher modulation frequency at a specified area after a distance image is created by intensity modulation of a laser light. CONSTITUTION:The frequency of a frequency varying oscillator 13 is set, for example, at 3MHz and a distance image is obtained on a distance image display device 12 to primarily determine a distance of 0-50m with the intensity modulation of a laser light from a laser 1. Based on the distance image, an area requiring high resolutions is selected and the frequency of the frequency variable oscillator 13 is set at a high value, for example, 60MHz for this area to acquire a distance image with higher resolutions.
