摘要： An object detection device includes a first generator (43), a second generator (44), a detector (45), and a divider (46). The first generator (43) generates a first map in which a pixel location of an image in a direction of one axis, a disparity value at the pixel location, and a disparity frequency at which the disparity value appears are associated with one another. The second generator (44) generates a second map obtained by converting a unit of a pixel location on the first map into a unit of an actual distance. The detector (45) detects a group of connected pixels that have a disparity frequency not less than a predetermined value on the second map as an isolated area where an object is present. The divider (46) divides the isolated area based on a disparity frequency of each pixel in the isolated area.

摘要： A distance measuring apparatus (100) includes a signal conversion unit (22) to match a format of a second signal relating to a distance to an object with a format of a first signal relating to an image; and a distance information output unit (24) to output distance information based on the first signal and the second signal having the format matched with the format of the first signal. The signal conversion unit (22) converts the second signal such that, among length information in directions of a plurality of dimensions held in the first signal and length information in directions of a plurality of dimensions held in the second signal, length information in a direction of at least one of the plurality of dimensions of the first signal represents length information in a direction of at least one of the plurality of dimensions of the second signal.
