This three-dimensional object detection device is provided with: an image conversion means (31) for converting the viewpoint of an image obtained by an image capturing means (10) to create a bird's-eye view image; a three-dimensional object detection means (33) for generating vehicle width direction waveform information by counting, along the vehicle width direction, a number of pixels that indicate a predetermined difference in a difference image in which the positions of bird's-eye view images taken at different times have been aligned, and forming a frequency distribution, and for performing, based on the vehicle width direction waveform information, vehicle width direction detection processing in which three-dimensional objects that are present within a detection area are detected; a three-dimensional object assessment means (34) for assessing whether a detected three-dimensional object is another vehicle that is present within the detection area; and a control means (34) for specifying a detection position for which a count number equal to or greater than a predetermined value has been obtained in the vehicle width direction detection processing, and suppressing assessment of the three-dimensional object as another vehicle to be detected when the specified detection position has moved within the detection area from the front toward the back in the host vehicle progress direction and arrived at a predetermined position within the detection area. |
