Publication number: 20230289490Abstract: An underground structure detection apparatus detects information including position/posture information based on a plurality of pieces of two-dimensional data indicating a cross section of the ground and three-dimensional data indicating the underground structure. Synthetic data is obtained by synthesizing the two-dimensional data and the three-dimensional data, and position/posture information of a component is corrected based on an image from the two-dimensional data. When a determination is made in a transverse direction with respect to a road, and the image feature is included in continuous images by a threshold or more, it is determined as a transverse pipe, and when a determination is made in a longitudinal direction with respect to a road, and the image feature is included in continuous images by a threshold or less, it is determined as a longitudinal pipe, and the posture is corrected for each direction.Type: ApplicationFiled: February 15, 2023Publication date: September 14, 2023Applicant: HITACHI, LTD.Inventors: Takashi Kanemaru, Xiaorui Qiao
