摘要： A method for automatically determining quality of registration of landmarks includes training an artificial intelligence (AI) system to detect inaccurate registration of landmarks. Training the AI system uses training data that includes scans of an environment captured by a 3D measuring device from corresponding scan points. A first scan is registered with at least a second scan based on one or more landmarks captured in the first scan and the second scan. Further, a model is created to identify incorrect registration by analyzing the training data. The analysis detects a mismatch in a first instance of a landmark in the first scan and a second instance of said landmark in the second scan. The model is then used to evaluate registration of landmarks in live data, the live data including a set of scans, the result identifying accuracy level of the registration of landmarks.

摘要： A method and system for scanning and measuring an environment is provided. The method includes providing a first three-dimensional (3D) measurement device. The 3D measurement device being operable in a helical mode or a compound mode, wherein a plurality of light beams are emitted along a first path defined by a first axis and a second axis in the compound mode and along a second path defined by the first axis in the helical mode. A mobile platform holding the 3D measurement device is moved from a first position. A first group of 3D coordinates of the area is acquired by the 3D measurement device when the mobile platform is moving. A second group of 3D coordinates of the area is acquired with a second 3D measurement device that with six-degrees of freedom (6 DOF). The first group of 3D coordinates is registered based on the third group of 3D coordinates.

摘要： A system and method for monitoring and servicing objects within a location. The system includes a scanner structured to measure coordinates of a point within a map of a location, an image capture device, a communications circuit structured to communicate with an external device or network, and a processor operably coupled to the scanner, the image capture device, and the communications circuit. The processor is configured to identify an object based on either an image captured by the image capture device or coordinates of a surface of the object measured by the scanner, to control the scanner to obtain a location of the object within the 2D map, and to control the communications circuit to transmit status data or a service request regarding the object and the location of the object to an external device or network.
