Title:
DETECTION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/076769
Kind Code:
A1
Abstract:
A detection device according to an embodiment comprises a first estimation unit, a second estimation unit, a third estimation unit, a projection unit, a computation unit, and a detection unit. The first estimation unit estimates a first location relation between different image capture locations. Employing a plurality of captured images which are captured at the different image capture locations and the first location relation, the second estimation unit estimates a spatial location and an error location within a captured image for estimation. The third estimation unit estimates a second location relation between an image capture location of the captured image for estimation and a road surface. Employing the second location relation, the projection unit projects the image capture location upon the road surface and obtains a first projection location, projects the spatial location upon the road surface and obtains a second projection location, and projects the error location upon the road surface and obtains a third projection location. The computation unit performs an update such that, upon a straight line which transects the first projection location and the second projection location, an object presence probability is higher for between the second projection location and the third projection location than for between the first projection location and the third projection location, thereby computing a presence probability. Employing the presence probability, the detection unit detects a boundary between the road surface and an object.
