Object detection apparatus and object detection method
First Claim
1. An object detection apparatus that includes a fusion target generation section that generates a fusion target by combining first target information, which is acquired as a reflected wave of a carrier wave, of an object present ahead of an own vehicle and second target information, which is acquired by image processing by an imaging unit, of the object present ahead of the own vehicle, and that detects the object by using the fusion target, the apparatus characterized by comprising:
- a first lateral position acquisition means that acquires a first lateral position indicating a position of the object with respect to a width direction of the own vehicle by using the fusion target;
a second lateral position acquisition means that acquires a second lateral position indicating a position of the object with respect to the width direction of the own vehicle by using the second target information, the second lateral position comprising a left lateral position corresponding to a left side of a rear end portion of the object and a right lateral position corresponding to a right side of the rear end portion of the object; and
a lateral position selection means that selects, as a lateral position of the object, the lateral position closest to the own vehicle in the width direction of the own vehicle among the first lateral position, the left lateral position and the right lateral position.

Abstract
An object detection apparatus includes a fusion target generation section that generates a fusion target by combining first target information, which is acquired as a reflected wave of a carrier wave, of an object present ahead of an own vehicle and second target information, which is acquired by image processing by an imaging unit, of the object present ahead of the own vehicle, and that detects the object by using the fusion target. The apparatus includes a first lateral position acquisition means that acquires a first lateral position indicating a position of the object with respect to a width direction of the own vehicle by using the fusion target, a second lateral position acquisition means that acquires a second lateral position indicating a position of the object with respect to the width direction of the own vehicle by using the second target information, and a lateral position selection means that selects, as a lateral position of the object, the lateral position closest to the own vehicle between the first lateral position and the second lateral position.

10. An object detection method characterized by comprising:
-
a step of generating a fusion target by combining first target information acquired as a reflected wave of a carrier wave and second target information acquired by image processing by an imaging unit; a step of acquiring a first lateral position indicating a position of an object with respect to a width direction of an own vehicle by using the fusion target; a step of acquiring a second lateral position indicating a position of the object with respect to the width direction of the own vehicle by using the second target information, the second lateral position comprising a left lateral position corresponding to a left side of a rear end portion of the object and a right lateral position corresponding to a right side of the rear end portion of the object; and a step of selecting, as a lateral position of the object, the lateral position closest to the own vehicle in the width direction of the own vehicle among the first lateral position, the left lateral position and the right lateral position.

11. An object detection apparatus that includes a fusion target generation section that generates a fusion target by combining first target information, which is acquired as a reflected wave of a carrier wave, of an object present ahead of an own vehicle and second target information, which is acquired by image processing by an imaging unit, of the object present ahead of the own vehicle, and that detects the object by using the fusion target, the apparatus characterized by comprising:
-
a first lateral position acquisition means that acquires a first lateral position indicating a position of the object with respect to a width direction of the own vehicle by using the fusion target; a second lateral position acquisition means that acquires a second lateral position indicating a position of the object with respect to the width direction of the own vehicle by using the second target information; a lateral position selection means that selects, as a lateral position of the object, the lateral position closest to the own vehicle between the first lateral position and the second lateral position; and an object type determination means that determines a type of the object specified by the fusion target, wherein the lateral position selection means selects the first lateral position as a lateral position of the target if the object is determined to be a pedestrian.
