Abstract
A laser scanner is used with a mixed reality device to track and/or locate objects in an environment, such as a construction site. In some configurations, mixed reality is used to assist laser scanning. A collection of data points representing a point cloud can be acquired with a laser scanner. A reference frame of a mixed-reality device is aligned to the data of the point cloud. A graphic is presented on a display of the mixed-reality device. The graphic is positioned on the display in relation to the environment, based on the reference frame of the mixed-reality device being aligned to data of the point cloud. An item in the environment is tracked (e.g., a hazard or a tool). Data is provided to the mixed-reality device regarding a position of the item in the environment.
