Abstract
A stop detection device includes: an acquirer that acquires multiple captured images captured in chronological order by a camera mounted on a vehicle; an image processor that performs image processing on acquired multiple captured images; and a detector that detects vehicle speed of a vehicle at a stop position based on a result of image processing. The image processor includes a stop position identification unit that detects a marking indicating a stop position from a captured image to identify a stop position, and a vehicle speed calculation unit that calculates vehicle speed by comparing captured images in chronological order. The vehicle speed calculation unit excludes a specific region from each of multiple captured images to compare captured images.
