Abstract

A central map can be used in a construction environment to help position devices and receive updates from devices to update the central map. Devices in the construction environment, such augmented-reality devices, laser scanners, total stations, satellite navigation receivers, and others can be used to provide “crowd-sourced” data to update the central map as the construction environment changes.

First claim

What is claimed is:

1 . A system for using maps at a construction site, the system comprising:
a first device comprising a first optical sensor, wherein the first device is an augmented-reality device, wherein the augmented-reality device is a head-mounted display; a second device comprising a second optical sensor comprising an electronic distance measurement tool, wherein the second device is configured to measure a position of a target at the construction site using the electronic distance measurement tool; one or more memory devices comprising instructions that, when executed, cause one or more processors to:
transmit a first map to the first device;
orient the first device to the construction site based on comparing information from the first optical sensor to the first map;
receive optical data acquired by the first optical sensor related to the position of the target;
revise the first map using the optical data from the first optical sensor to generate a second map;
transmit the second map to the second device; and
orient the second device to the construction site based on comparing information from the second optical sensor to the second map;
receive optical data acquired by the second optical sensor, including the position of the target measured using the electronic distance measurement tool;
revise the second map using the optical data from the second optical sensor to generate a third map; and
orient a third device to the construction site based on the third map.

2 . The system of claim 1 , wherein the information from the first optical sensor is a local map of the augmented-reality device.

3 . The system of claim 1 , wherein:
the second device is a robot; and the instructions, when executed, further cause the one or more processors to automatically position the robot at the construction site based on orienting the second device to the construction site.

4 . The system of claim 1 , wherein the first map is based on data from a robotic total station.

5 . The system of claim 1 , wherein the second device comprises a robotic total station.

6 . A method for using maps at a construction site, the method comprising:
receiving a first map of at least a portion of the construction site; transmitting the first map to a first device, wherein the first device comprises a first optical sensor, wherein the first device is an augmented-reality device, and wherein the augmented-reality device is a head-mounted display; orienting the first device to the construction site based on comparing information from the first optical sensor to the first map; receiving optical data acquired by the first optical sensor; revising the first map using the optical data from the first optical sensor to generate a second map; transmitting the second map to a second device, wherein the second device comprises a second optical sensor that comprises an electronic distance measurement tool, orienting the second device to the construction site based on comparing information from the second optical sensor to the second map; measuring a position of a target at the construction site using the electronic distance measurement tool; receiving optical data acquired by the second optical sensor, including the position of the target measured using the electronic distance measurement tool; revising the second map using the optical data from the second optical sensor to generate a third map; and orienting a third device to the construction site based on the third map.

7 . The method of claim 6 , wherein the first map is based on data from a laser scanner.

8 . The method of claim 6 , wherein information from the first optical sensor is a local map of the augmented-reality device.

9 . The method of claim 6 , wherein receiving the optical data acquired by the second optical sensor occurs within 24 hours from receiving the optical data acquired by the first optical sensor.

10 . The method of claim 6 , wherein the construction site is an environment for receiving global navigation satellite system signals.

11 . The method of claim 6 , further comprising updating the second map based on data from a total station.

12 . The method of claim 6 , wherein the first map includes labels of features in the construction site.

13 . The method of claim 6 , wherein the second map includes color-coding to distinguish optical data acquired by the first device from data in the first map.

14 . A method for updating maps of an environment, the method comprising:
transmitting a first map to a first device, wherein the first device comprises a first optical sensor, wherein the first device is an augmented-reality device, and wherein the augmented-reality device is a head-mounted display; orienting the first device to the environment based on comparing information from the first optical sensor to the first map; receiving optical data acquired by the first optical sensor, after transmitting the first map to the first device; revising the first map using the optical data from the first optical sensor to generate a second map; receiving optical data acquired by a second optical sensor of a second device, after generating the second map, wherein the second device comprises an electronic distance measurement tool; measuring a position of a target in the environment using the electronic distance measurement tool; revising the second map using the optical data from the second optical sensor, including the position of the target measured used the electronic distance measurement tool, to generate a third map; and orienting a third device to a construction site based on the third map.

15 . The method of claim 14 , wherein:
the first map is based on data from a laser scanner.

16 . The method of claim 14 , wherein receiving the optical data acquired by the second optical sensor occurs within 72 hours from receiving the optical data acquired by the first optical sensor.

17 . The method of claim 14 , further comprising transmitting the third map to the third device, wherein the third device comprises an optical sensor.

18 . The method of claim 14 , further comprising:
transmitting the second map to the second device; and orienting the second device to the environment based on comparing information from the second optical sensor to the second map.
