Abstract
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.
Claims20
A system for using augmented reality for building layout, the system comprising:
- a surveying pole;
- a base station;
- a wearable device comprising a camera;
- and
- one or more memory device containing instructions that, when executed, cause one or more processors to perform the following steps:
- determining a position of the surveying pole with respect to the base station, wherein a location of the base station is calibrated with respect to an environment;
- measuring a location of a first point using the surveying pole based on the position of the surveying pole with respect to the base station;
- determining that the surveying pole is out of a line of sight of the base station;
- generating a local map based on images acquired by the camera of the wearable device;
- determining an offset of the surveying pole with respect to the local map based on images of the surveying pole acquired by the camera, wherein the offset is determined after determining that the surveying pole is out of the line of sight of the base station;
- and
- measuring a location of a second point based on the offset of the surveying pole with respect to the wearable device.
A method for using augmented reality for building layout, the method comprising:
- determining a position of a surveying pole with respect to a base station, wherein a location of the base station is calibrated with respect to an environment;
- measuring a location of a first point using the surveying pole based on the position of the surveying pole with respect to the base station;
- determining that the surveying pole is out of a line of sight of the base station;
- generating a local map based on images acquired by a camera of a wearable device;
- calculating an offset of the surveying pole with respect to the local map based on images of the surveying pole acquired by the camera, wherein:
- the surveying pole can move independently from the camera of the wearable device;
- and
- the offset is determined after determining that the surveying pole is out of the line of sight of the base station;
- and
- measuring a location of a second point using the surveying pole based on the offset of the surveying pole with respect to the wearable device.
A wearable device comprising:
- a frame;
- a camera coupled with the frame;
- and
- one or more memory devices containing instructions that, when executed, cause one or more processors to perform the following steps:
- determining that a surveying pole is out of a line of sight of a base station;
- generating a local map based on images acquired by the camera;
- determining an offset of the surveying pole with respect to the local map based on images of the surveying pole acquired by the camera, wherein the offset is determined after determining that the surveying pole is out of the line of sight of the base station;
- and
- measuring a location of a point based on the offset of the surveying pole with respect to the wearable device.
