Object detection device

Abstract

By response to change in environmental temperature to generate an error detection difficult to provide an object detection apparatus. Object detecting apparatus is provided with an obtaining unit for obtaining a thermal image from the sensor unit, a storage unit, and a detection unit for detecting an object for storing a background image and the update to update the background image unit. Object detecting apparatus, by the background difference method to detect a difference from the acquisition of the current image and the background image deterioration merchant, and detects the object from the detector. For the updating unit, the object is not detected area is detected on the basis of the most recent acquired image of the background image is updated. Updating unit, for detecting the object region is detected, the first background to obtain a correction value from the amount of change in temperature is updated by the updating process, by using this correction value and updates the background image.
