Abstract
In measurement using infrared images that are obtained by nighttime aerial photography, a correspondence relationship between the infrared images is determined with high accuracy by the following method. In this method, agricultural land is photographed from the air at night by using an infrared camera mounted on a UAV. In the state in which multiple infrared light emitting points are installed on agricultural land, the agricultural land is photographed multiple times by the infrared camera while the UAV flies at night in such a manner that a part of the agricultural land is commonly contained in multiple infrared photographic images. Then, a correspondence relationship between the multiple infrared photographic images is determined by using bright points of the infrared light emitting points in the part of the agricultural land commonly contained in the infrared photographic images.
