Pedestrian detecting device for vehicle
First Claim
1. A pedestrian detecting device for a vehicle, which is installed in the vehicle, comprising:
- an image pickup device to pick up a far-infrared image outside the vehicle;
an environment detecting device to detect an environment outside the vehicle that influences the far-infrared image picked up by the image pickup device;
a pedestrian-model storing device to store data of a pedestrian model in the far-infrared image to be picked up by the image pickup device in association with the environment outside the vehicle to be detected by the environment detecting device;
an area-candidate extracting device to extract a candidate of an area that contains a pedestrian image from the far-infrared image picked up by the image pickup device;
a pedestrian-model extracting device to extract a specified pedestrian model from the stored data of the pedestrian model that is stored in the pedestrian-model storing device, the specified pedestrian model being associated with the environment outside the vehicle that is detected by the environment detecting device; and
a pedestrian determining device to determine, for a pedestrian detection, whether or not the area candidate contains the pedestrian image, by comparing the area candidate extracted by the area-candidate extracting device to the pedestrian model extracted by the pedestrian-model extracting device.

Abstract
A pedestrian detecting device for a vehicle comprises a far-infrared camera picking up a far-infrared image outside the vehicle, an area-candidate extracting portion extracting an area candidate containing a pedestrian image from the far-infrared image picked up, an environment detecting device detecting an environment outside the vehicle that influences the far-infrared image, a ROM storing a pedestrian model in the far-infrared image in association with the environment outside the vehicle, a pedestrian-model extracting portion extracting a pedestrian model associated with the environment that is detected by the environment detecting device from the ROM, and a pedestrian determining portion determining, for a pedestrian detection, whether or not the area candidate contains the pedestrian image, by comparing the area candidate extracted to the pedestrian model extracted. Accordingly, the detection accuracy of the pedestrian can be improved.
