Abstract
The object recognition apparatus has an active range finder having a floodlight unit which floodlights a light onto a target object, and determines a distance up to a target object on the basis of a reflected light therefrom, a stereo camera to determine a distance up to the target object on the basis of image information from the target object, an object recognition unit which recognizes the target object on the basis of an output signal from the active range finder and an output signal from the stereo camera, and a fill light control unit which controls the floodlight unit to operate so as to irradiate a light floodlit by the floodlight unit as a fill light of the stereo camera.
Claims32
An object recognition apparatus comprising:
- an active range finder having a floodlight unit which floodlights a light onto a target object, and determines a distance up to a target object on the basis of a reflected light therefrom;
- a stereo camera to determine a distance up to the target object on the basis of image information from the target object;
- an object recognition unit which recognizes the target object on the basis of an output signal from the active range finder and an output signal from the stereo camera;
- and
- a fill light control unit which controls the floodlight unit to operate so as to irradiate a light floodlit by the floodlight unit of the active range finder as a fill light of the stereo camera.
An object recognition apparatus comprising:
- an active range finder having a floodlight unit which floodlights a light onto a target object, and determines a distance up to a target object on the basis of a reflected light therefrom;
- a stereo camera to determine a distance up to the target object on the basis of image information from the target object;
- an object recognition unit which recognizes the target object on the basis of an output signal from the active range finder and an output signal from the stereo camera;
- a fill light control unit which controls the floodlight unit to operate so as to irradiate a light floodlit by the floodlight unit of the active range finder as a fill light of the stereo camera;
- and
- a cover glass disposed in front of the stereo camera, wherein,
- with respect to the cover glass, a predetermined region including a region into which a light that is floodlit from the floodlight unit of the active range finder, and is reflected from the target object, is incident serves as an infrared radiation permeable region, and a region other than the predetermined region serves as an infrared radiation permeability-limited region.
An on-board object recognition apparatus comprising:
- an active range finder having a floodlight unit which floodlights a light onto a target object, and determines a distance up to a target object on the basis of a reflected light therefrom;
- a stereo camera to determine a distance up to the target object on the basis of image information from the target object;
- an object recognition unit which recognizes the target object on the basis of an output signal from the active range finder and an output signal from the stereo camera;
- a fill light control unit which controls the floodlight unit to operate so as to irradiate a light floodlit by the floodlight unit of the active range finder as a fill light of the stereo camera;
- and
- an operation condition input unit to input an operation condition of a vehicle, wherein
- the fill light control unit determines an irradiating range of the floodlight unit as a fill light irradiation unit on the basis of an operation condition inputted by the operation condition input unit.
