Abstract: An image processing device includes a detection unit, a feature amount generating unit, a tracking unit, a feature amount change detecting unit, a tracking history extracting unit, and a determination unit, so that when occlusion in a selected cluster has occurred, the image processing device can determine whether or not objects are identical without using data of an image in which the occlusion has occurred. An image in which the occlusion has occurred can be excluded by using the data of the image determined to have no change in the feature amount, whereby a decrease in accuracy of determining whether or not the objects are identical can be suppressed.

Abstract: A route prediction unit estimates a route of an object of interest with respect to a target object based on collision avoidance models. A collision risk estimation unit calculates collision risks between the object of interest and target object for each collision avoidance model. A collision deciding unit decides the presence or absence of a collision from the collision risks and feeds back a collision avoidance model correction value to the route prediction unit when it is determined that the collision occurs. A collision avoidance route selector selects any of the plurality of collision avoidance models in which the absence of collision is decided by the collision deciding unit, and selects a route of the collision avoidance model as a route for avoiding the collision between the objects. The route prediction unit performs a new route prediction using the collision avoidance model correction value.
