    摘要: An object detection apparatus (10)is provided for detecting both stationary objects and moving objects accurately from an image captured from a moving mobile unit.
    The object detection apparatus (10) of the present invention applies Gabor filter to two or more input images captured by an imaging device (12) such as CCD camera mounted on a mobile unit, and calculates (2, 3, 4) optical flow of local areas in the input images. Then the object detection apparatus closely removes optical flow produced by motion of the mobile unit by estimating optical flow produced from background of the input images. In other words, the object detection apparatus clarifies the area where object is not present ("ground") in the input images. By removing such "ground" part, the area where objects seems to be present ("feature") is extracted from the input images. Finally, the object detection apparatus (10) determines (7) whether objects are present or not using flow information of the extracted "feature" part.

    摘要: An object detection apparatus and method capable of detecting objects based on visual images captured by a self-moving unit. A sequential images output section makes a train of a first input image and a second input image sequential to the first input image and outputs said train. A local area image processor calculates local flows based on said first input image and said second input image. An inertia information acquiring section measures self-motion of the unit to calculate inertia information thereof. A global area image processor uses said inertia information to estimate global flow, which is a motion field of the entire view associated to the self-motion, using said global flow and said first input image and creates a predictive image of said second input image. The global area image processor then calculates differential image data, which is a difference between said predictive image and said second input image. A figure-ground segregation section uses said differential image data to refine said local flows and compares the refined local flows with a predetermined threshold value to extract a figure candidate area, which is the area having a high probability of an object existing in the input image. An object presence/absence determination section determines presence/absence of objects in said figure candidate area.
