PROBLEM TO BE SOLVED: To provide an information acquisition apparatus and an object detection system that are capable of appropriately and effectively acquiring information on distance to an object to be detected.SOLUTION: An information acquisition apparatus comprises: a projection optical system 100 for projecting laser beams to a target area with a predetermined dot pattern; a beam receiving optical system 200 for taking an image of the target area with a CMOS image sensor; a memory part for holding a reference template based on a reference image; and a distance acquisition part for acquiring distance information for a segment area, based on a moving position, of the segment area allocated for the reference image, on an actually measured image. Based on a detected border of an object, the distance acquisition part sets a searching range LI that is longer than a searching range L0. |
