Image processing apparatus and image processing method

Abstract

According to one embodiment, an image processing apparatus and an image processing method includes a processed image generation unit, a provisional detection unit, and a final detection unit. The processed image generation unit generates a processed image for detection processing from an image around a vehicle taken by a camera provided on the vehicle. The provisional detection unit scans a scanning frame of a predetermined size according to a detection target object on the processed image, and detects a plurality of position candidate regions of the detection target object within the processed image by determining a feature value for respective scanning positions using a dictionary of the detection target object. The final detection unit determines an overlapping region of the plurality of position candidate regions, and determines a final detection position of the detection target object within the processed image based on the overlapping region and the plurality of position candidate regions.

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Japanese Patent Application No. 2014-060738 filed on March 24, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The embodiments described herein generally relate to an image processing device and an image processing method. Background technique [0004] Recently, in-vehicle cameras for picking up images of situations around the vehicle are mounted on more and more vehicles such as automobiles. Images picked up by on-board cameras are very useful because by detecting objects in the images, the images can be used to determine the likelihood of a collision between the vehicle and the object or to support the steering of the vehicle while parked.

Furthermore, even when a plurality of dictionaries are used, in the case where the shape of the object in the processing image changes, such as when the object loses bilateral symmetry, the probability calculated by the processing using the respective dictionaries becomes lower than the predetermined possibility. properties, making it extremely difficult to detect objects
