Image processing apparatus and image processing method
First Claim
1. An image processing apparatus comprising:
- a dictionary generation unit configured to generate a dictionary as a single dictionary in advance using a plurality of images of a detection target object picked up in advance by a camera, the camera being provided on a vehicle and picking up an image around the vehicle with a wide viewing angle, the plurality of images being obtained by arranging the detection target object at a corresponding plurality of positions in a predetermined range within an image-pickup range of the camera so as to make a predetermined visual axis of the camera and a normal-line direction of a detection target surface of the detection target object parallel to each other, and the plurality of images being obtained by picking up each of the plurality of images by the camera at the corresponding plurality of positions;
a processed image generation unit configured to generate a processed image having the predetermined visual axis as a normal-line direction, based on an image picked up by the camera after generation of the dictionary; and
a detection unit configured to detect the detection target object included in the processed image by determining a feature value using the dictionary.

Abstract
According to one embodiment, an image processing apparatus and an image processing method includes a dictionary generation unit, a processed image generation unit, and a detection unit. The dictionary generation unit generates a single dictionary using a plurality of images of a detection target object picked up by a camera. The plurality of images is obtained by arranging the detection target object at a corresponding plurality of positions in a predetermined range such that a predetermined visual axis of the camera is parallel with a normal-line direction of a detection target surface of the detection target object. The processed image generation unit generates a processed image having the predetermined visual axis as a normal-line direction, based on an image picked up by the camera after generation of the dictionary. The detection unit detects the detection target object included in the processed image by determining a feature value using the dictionary.
