Patent number: 11893721Abstract: A defect detection apparatus includes a defect detection unit and a calculation unit. The defect detection unit detects a defect that appears on an external appearance of a structure through imaging processing from external appearance image data that is generated by imaging the external appearance of the structure with a surveying instrument. The calculation unit calculates defect data relating to the defect detected by the defect detection unit by using coordinate data that is correlated with the external appearance image data.Type: GrantFiled: June 11, 2018Date of Patent: February 6, 2024Assignee: NIKON-TRIMBLE CO., LTD.Inventor: Yuichi Ohshima

Patent number: 11132789Abstract: A target including a reference object of a known size is prepared. The reference object from target image data, which is generated by photographing the target using a survey instrument, is detected through image processing to calculate first size data on dimensions of the reference object. A defect from external appearance image data, which is generated by photographing an external appearance of a structure using the survey instrument, is detected through image processing to calculate defect data on dimensions of the defect. The first size data is compared with second size data on actual dimensions of the reference object to calculate correction data, which is used to correct the defect data.Type: GrantFiled: June 14, 2017Date of Patent: September 28, 2021Assignee: NIKON-TRIMBLE CO., LTD.Inventor: Yuichi Ohshima

Patent number: 6753951Abstract: By providing a diffusing plate between a laser diode and an objective lens, a measurement light flux emitted from the laser diode is irradiated on a corner cube in a defocused state via the objective lens. The light flux having been reflected at corner cube sustains the defocused state. The reflected light flux having been reflected at and having exited the corner cube becomes condensed onto an avalanche photodiode through the objective lens. Even when a vibration occurs at the corner cube, the reflected light flux is received at the avalanche photodiode as long as the light flux having been reflected at and having exited the corner cube is within the predetermined range.Type: GrantFiled: August 5, 2002Date of Patent: June 22, 2004Assignees: Nikon Trimble Co., Ltd., Nikon CorporationInventor: Satoshi Fukumoto
