摘要： A system for integrating high-density laser scanner data with mixed-reality is disclosed. In some implementations, the system may acquire, using a laser scanner, a collection of data points representing a three-dimensional point cloud, wherein the laser scanner includes: a laser configured to generate an optical beam; a beam-steering device configured to steer the optical beam; and a detector configured to receive light from the optical beam, after light from the optical beam is reflected from an object in an environment. The system may transmit data of the point cloud to the augmented-reality device, wherein the augmented-reality device comprises: one or more cameras configured to acquire images of the environment; and a display configured to render graphics on the display. The system may align a reference frame of the augmented-reality device to the data of the point cloud. The system may present a graphic on the display of the augmented-reality device, wherein the graphic is positioned on the display in relation to the environment based on the reference frame of the augmented-reality device being aligned to data of the point cloud.

摘要： 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.

摘要： An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.
