摘要： A technique of determining the situation of a traffic lane. A traffic lane situation determining device includes a camera that is mounted in a vehicle and obtains an image whose object is a road in a travelling direction of the vehicle, a straight line detecting section that extracts a plurality of lines defining a traffic lane of the road from the image to detect a plurality of straight lines that respectively approximate the plurality of lines, an intersection identifying section that identifies an intersection of extended lines respectively obtained by extending the plurality of straight lines, and a traffic lane situation determining section that compares a location of the intersection with a location of a point at infinity preset in the image to determine a situation of the traffic lane.

摘要： In an object detection apparatus (1), a window setting unit (12) extracts a window (52) from an edge image (22), to thereby generate an ordinary window image (23). When an edge strength of the ordinary window image (23) is not larger than a usage reference value, a used image determination unit (15) determines to use the ordinary window image (23) for calculation of an identification value (30) indicating a degree of presence of a pedestrian in the window (52). When the edge strength of the ordinary window image (23) is larger than the usage reference value, a pixel value correction unit (13) generates a corrected window image (24) having an edge strength smaller than that of the ordinary window image (23) from the ordinary window image (23). When the edge strength of the corrected window image (24) is not larger than the usage reference value, the used image determination unit (15) determines the corrected window image (24) to be used for calculation of the identification value (30).

摘要： In a human detection device 1, an edge extractor 11 carries out edge extraction processing to an input image 21 and produces a horizontal edge image 22. A shoulder detector 12 detects a shoulder center and a shoulder width of a person included in the input image 21. A foot detector 13 detects a foot position of the person based on the detected shoulder center and shoulder width. A top detector 14 detects a top position of the person based on the detected shoulder center and shoulder width. A size determiner 15 determines a horizontal size of the person based on the detected shoulder width and determines a vertical size of the person based on the detected foot position and top position. The size determiner 15 produces human range data 28 including the determined sizes, the shoulder center position, the foot position, and the top position.
