[0036] (overall configuration)

[0037] figure 1 is a block diagram showing one configuration example of the image processing apparatus 10 according to the first embodiment of the present invention.

[0038] The image processing device 10 includes a camera 11 , a control unit 12 , a storage unit 13 , an illumination device 16 , a speaker 17 , a speaker 18 and a display device 19 .

[0039] The video camera 11 includes a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and captures a video image of an area around a vehicle such as a private car, and generates and supplies image data to the control unit 12 .

[0040] For example, in the case of monitoring the rear of the vehicle, the camera 11 is provided near the license plate of the rear of the vehicle or in the upper portion of the rear window glass (rear camera). In addition, in the case of monitoring the lateral direction of the vehicle, the camera 11 is installed...

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.

Description

[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. [0005] Image processing techniques for detecting objects within images (images based on picked-up images and including processing target objects; hereinafter, referred to as "p...
