A position estimation device estimates a position of a vehicle during a reverse operation. The position estimation device includes a reverse operation detection unit, an illumination instruction unit, an image obtaining unit, and position estimation unit. The reverse operation detection unit detects the reverse operation of the vehicle. The illumination instruction unit instructs a light source device to illuminate a rear area of the vehicle with near-infrared light when the reverse operation is detected. The image obtaining unit obtains an image of the rear area of the vehicle, and the image is captured by an imaging device of the vehicle while the rear area is being illuminated with the near-infrared light. The position estimation unit detects a feature point of the image using a feature point extraction device or algorithm based on luminance information of the image, and estimates the vehicle position using the detected feature point.
