A surroundings detection device includes an infrared light projector, an infrared camera, and a processor. The infrared light projector is configured to output infrared light by switching between a uniform irradiation mode in which a predetermined range is irradiated with the infrared light, and a pattern irradiation mode in which the predetermined range is irradiated with the infrared light in a predetermined pattern. The processor is configured to: generate an image with brightness distribution for the predetermined range reflected by a target present in the predetermined range; and generate an image with pattern distribution for the predetermined range reflected by a target present in the predetermined range, and detect the distance to the target in the predetermined range based on the image with pattern distribution.
