Title:
OBJECT DETECTION DEVICE AND INFORMATION ACQUISITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/102025
Kind Code:
A1
Abstract:
Disclosed are an information acquisition device which can accurately acquire information on a target region by means of a simple-structure, and an object detection device which has the information acquisition device built-in. An information acquisition device (1) has: a laser light source (111) which emits laser light having a wavelength in the region of 830nm; a projection optical system (10) which projects the laser light toward a target region; and a CMOS image sensor (125) which receives the light reflected from the target region and outputs a signal. Second imaging data, which is output from the CMOS image sensor (125) when laser light is not emitted, is subtracted from first imaging data, which is output from the CMOS image sensor (125) when laser light is emitted, and the result of the subtraction is stored in a memory (25). A 3D distance calculation unit (21c) calculates and acquires 3D distance information on the basis of the subtraction result stored in the memory (25).
