摘要： The object recognition device includes at least one sensor, a data reception unit, and a setting unit. The sensor detects an object present in a detectable range and transmits object data including a plurality of physical quantities indicating a state of the object. The data reception unit receives the object data from the sensor. The setting unit generates prediction data which predicts current object data based on at least a part of past object data received by the data reception unit and a motion model in the object, and sets a association possible region for determining a association between the prediction data and the current object data based on a plurality of physical-quantity delay times each corresponding to each of the plurality of physical quantities included in the prediction data.

摘要： Provided is a road wall shape estimation device for estimating the shape of a road wall at a long distance from a vehicle, with high accuracy. This road wall shape estimation device includes: a filter processing unit which sets a plurality of filters, and among observation points acquired by an observation data acquisition unit, outputs only observation points whose relative-to-ground velocities are equal to or smaller than a predetermined value and whose positions are inside the filters; a reference point calculation unit which calculates reference points from the output of the filter processing unit; and a road wall estimation unit which estimates the shape of the road wall from the reference points. The filter processing unit increases the width of each filter as the position of the filter becomes farther from an own vehicle.

摘要： In this object recognition device, an association between a first object detection result and a second object detection result is taken in a region excluding an occlusion area. When the first object detection result and the second object detection result are determined to be detection results for an identical object, a recognition result of the surrounding object is calculated from the first object detection result and the second object detection result. Thus, occurrences of erroneous recognition of an object can be decreased as compared to a conventional object recognition device of a vehicle.
