Abstract

An object detection device, including: an imaging unit (400) that is mounted on a movable body; an object detection unit (201) that calculates an image displacement of a partial image between two images captured by the imaging unit (400) at different times, and performs detection processing to detect an object in an image based on at least the image displacement; and a control unit (201) that changes a manner of performing the detection processing based on a position in the image in a lateral direction of the movable body.

Description

technical field [0001] The invention relates to a target detection device for detecting targets. Background technique [0002] Conventionally, devices described in Japanese Patent Application Publication No. 2008-276308 (JP-A-2008-276308), Japanese Patent Application Publication No. 2008-238927 (JP-A-2008-238927) and the like can be used for Probe target. JP-A-2008-276308 describes a video processing device that detects optical flow from video captured by an imaging element mounted on a movable body. The above-mentioned video processing device includes a calculation unit for dividing the frame contained in the video into a plurality of regions and calculating the optical flow of each region under different conditions; and a parameter determination unit for to change at least the mode or condition of frame division. The device changes the frame interval between the target frame and the reference frame, and is used to detect the optical flow according to whether the target ...
