To provide a three-dimensional survey apparatus, a three-dimensional survey method, and a three-dimensional survey program which are capable of suppressing an occurrence of a data-deficient part. A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. If there is a data-deficient part where three-dimensional data is not acquired among a measurement object when the scanner unit acquires point cloud data, the control calculation portion executes control to replenish the three-dimensional data related to the data-deficient part having been acquired by the collimating ranging unit to the point cloud data having been acquired by the scanner unit.

The system includes a scanner having a first light source, an image sensor, a second light source and a controller, the second light source emitting a visible light, the controller determining a distance to points based on a beam of light emitted by the first light source and receiving of the reflected beam of light from the points. Processors are operably coupled to the scanner execute a method comprising: generating a map of the environment; emitting light from the second light source towards an edge defined by at least a pair of surfaces; detecting the edge based on emitting a second beam of light and receiving the reflected second beam of light; and defining a room on the map based on the detecting of the corner or the edge.

Methods and systems for modelling pipeline construction, include or implement steps of (a) obtaining ranging data of a pipeline construction location including a pipe; (b) processing the ranging data to produce a spatially organized point cloud; and (c) processing the point cloud to identify at least one geometric feature comprising a point or a two-dimensional feature representative of a pipe centreline, and associating the at least one geometric feature with the pipeline construction location. The ranging data may be data obtained from a lidar device. The pipeline construction may be underground construction, where pipe is laid in a ditch. Relevant information, such as depth-of-cover may be calculated from identified geometric features. Relevant information may be determined in real-time or near-real-time and displayed, communicated or recorded as desired.

Three-dimensional (3D) point cloud generation using a stationary laser scanner and a mobile scanner. The method includes scanning a first part of a surrounding with the stationary laser scanner, obtaining a first 3D point cloud, scanning a second part of the surrounding with the mobile scanner, obtaining a second 3D point cloud, whereby there is an overlap region of the first part and the second part, and aligning the second 3D point cloud to the first 3D point cloud to form a combined 3D point cloud. The positional accuracy of points of the second 3D point cloud is increased by automatically referencing second scanner data of the overlap region, generated by the mobile scanner, to first scanner data of the overlap region, generated by the stationary laser scanner. Therewith, deformations of the second 3D point cloud and its alignment with the first 3D point cloud are corrected.

A surveying instrument comprises a light projecting optical system for projecting a distance measuring light to a predetermined measuring point, a light receiving optical system for receiving a reflected distance measuring light and an infrared light from the measuring point, and an arithmetic control module for controlling a distance measurement and a temperature measurement based on light receiving results of the reflected distance measuring light and the infrared light, and the arithmetic control module measures a distance to the measuring point based on light receiving results of the reflected distance measuring light received by a photodetector of the light receiving optical system, and measures a temperature of the measuring point based on light receiving results of the infrared light received by a temperature sensor of the light receiving optical system.

The scanner calculates a direction angle of the leveling base based on the encoder pattern read angle and the offset angle of the target unit, calculates coordinates of an installation point of the target unit based on the measured coordinates of the target and the direction angle of the target, and calculates a direction angle of the scanner based on the offset angle of the scanner and the direction angle of the leveling base on which the scanner is mounted.

A surveying pole is part of a primary surveying system (e.g., a Global Navigation Satellite System (GNSS) or a total station). Cameras are mounted to the surveying pole and used for ground tracking as the survey pole is moved from a place where the primary surveying system is unimpeded to an environment where the primary surveying system is impaired (e.g., to a GNSS-impaired environment or to a position that is blocked from view of the total station). Using ground tracking and/or other sensors, surveying can be continued even though the primary surveying system is impaired.
