Abstract: A storage device stores a first and a second feature point maps of an object in advance, the first feature point map detected by image processing not based on deep learning, and the second feature point map detected using a deep learning model trained in advance. A processing circuit detects first feature points of the object by the image processing on a captured image. The processing circuit detects second feature points of the object from the captured image using the deep learning model. The processing circuit calculates a position of a target object based on the first feature points and the first feature point map. When the position cannot be calculated based on the first feature points and the first feature point map, the processing circuit calculates the position of the target object based on the first and second feature points, and he first and second feature point maps.

Abstract: A relative position calculator calculates relative position and attitude of a vehicle based on images captured by an image capturing apparatus on the vehicle. An absolute position calculator extracts a marker from an image captured by the image capturing apparatus, and calculates absolute position and attitude of the vehicle, based on position and attitude of the one extracted marker. A corrector calculates the corrected position and attitude, not using the absolute position and attitude calculated based on the position and attitude of the marker when a difference or ratio of an apparent height and width of the marker in the image is equal to or smaller than a threshold, but using the absolute position and attitude calculated based on the position and attitude of the marker when the difference or ratio is larger than the threshold.

Abstract: A vehicle monitoring device includes a positioning device, a distance calculator, a first imaging device, a volume calculator, and a work calculator. The positioning device measures a position of a vehicle including a loading platform. The distance calculator calculates a movement distance of the vehicle based on the position of the vehicle measured by the positioning device. The first imaging device captures an image of a load mounted on the loading platform. The volume calculator calculates a volume of the load based on the image captured by the first imaging device. The work calculator calculates a work of the vehicle based on the movement distance and the volume of the load.
