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 comprising:
- a light source configured to direct light to form a target on a surface;
- a wearable device separate from the light source, the wearable device comprising:
- a camera;
- and
- a display;
- one or more processors configured to:
- measure a relative location of the target to a base station;
- generate a local map based on a plurality of images acquired by the camera, wherein the local map includes a relative location of the target to the wearable device;
- orient the local map to an environment of the base station based on the relative location of the target to the base station, the relative location of the target to the wearable device, and a relative location of the base station to the environment;
- and
- present, on the display of the wearable device, a virtual object in relation to the environment and/or measure one or more coordinates of a physical object, based on orienting the local map of the wearable device with the environment.
A method comprising
- directing light, from a light source, to form a target on a surface;
- measuring a relative location of the target to a base station;
- generating a local map based on images acquired by a camera of a wearable device, wherein the local map includes a relative location of the target to the wearable device;
- orienting the local map to an environment of the base station based on the relative location of the target to the base station, the relative location of the target to the wearable device, and a relative location of the base station to the environment;
- and
- presenting, on a display of the wearable device, a virtual object in relation to the environment and/or measuring one or more coordinates of a physical object, based on orienting the local map of the wearable device with the environment.

- and
- present, on the display of the wearable device, a virtual object in relation to the environment and/or measure one or more coordinates of a physical object, based on orienting the local map of the wearable device with the environment.
