Abstract

A computerized system is disclosed. The computer system executes software that receives a geographic location having one or more coordinates of a roof, receives a validation of the location of the roof, and generates unmanned aircraft information based on the one or more coordinates of the validated location. The unmanned aircraft information includes an offset from the roof to direct an unmanned aircraft to fly an autonomous flight path above the roof, and camera control information to direct a camera of the unmanned aircraft to capture images of the roof at a predetermined time interval while the unmanned aircraft is flying the flight path. The computer system receives images of the roof captured by the camera while the unmanned aircraft is flying the autonomous flight path and generates a structure report for the roof based at least in part on the images.

First claim

What is claimed is:

1. A computerized system, comprising:
a computer system having an input unit, a display unit, one or more processors, and one or more non-transitory computer readable medium, the one or more processors executing software to cause the one or more processors to:
receive a geographic location, the geographic location having one or more coordinates of a roof;
receive, via the input unit, a validation of the location of the roof;
subsequent to receiving the validation of the location of the roof, generate unmanned aircraft information based on the one or more coordinates of the validated location, the unmanned aircraft information including an offset from the roof to direct an unmanned aircraft to fly an autonomous flight path above the roof, and camera control information to direct a camera of the unmanned aircraft to capture images of the roof at a predetermined time interval while the unmanned aircraft is flying the flight path, the predetermined time interval and the offset set so that the captured images overlap ensuring complete coverage of the roof;
receive the images of the roof captured by the camera while the unmanned aircraft is flying the autonomous flight path from the unmanned aircraft; and
generate a structure report for the roof based at least in part on the images.

2. The computerized system of claim 1 , wherein a first image and a second image of the roof are correlated and a three-dimensional model of the roof is generated based at least in part on the correlation between the first and second received images.

3. The computerized system of claim 1 , wherein the unmanned aircraft is a multi-rotor aircraft.

4. The computerized system of claim 1 , further comprising displaying, on the display unit, one or more images depicting an aerial view of the roof, and causing the one or more processors to display a drag and drop element on the aerial view of the roof, and wherein receiving, via the input unit, an alteration of the one or more coordinates of the roof includes a user moving the drag and drop element on the display unit from the geographic location to a second geographic location.

5. The computerized system of claim 1 , wherein the computer system has a Geographic Positioning System (GPS), and wherein the geographic location is determined by the GPS.

6. The computerized system of claim 1 , wherein the geographic location is determined by an address of the roof.

7. The computerized system of claim 1 , wherein the geographic location is determined by scrolling on a map displayed on the display unit.

8. The computerized system of claim 1 , wherein the unmanned aircraft is provided with a gimbal and the camera control information includes gimbal control information configured to align the camera of the unmanned aircraft perpendicular to the roof.

9. An unmanned aerial vehicle, comprising:
a body;
a source of propulsion connected to the body;
a camera supported by the body and configured to capture aerial images;
a collision detection and avoidance system supported by the body, the collision detection and avoidance system comprising at least one distance detector; and
one or more processors supported by the body, and executing instructions configured to:
receive a flight path, wherein the flight path comprises instructions for the unmanned aerial vehicle to travel from its current location to at least one other location adjacent to a roof, the flight path including an offset from the roof directing the unmanned aerial vehicle to maintain a vertical and a lateral offset from the roof;
detect, with the collision detection and avoidance system, an obstacle for avoidance by the unmanned aerial vehicle based at least in part on the flight path going through the obstacle;
receive distance data generated by the collision detection and avoidance system concerning at least the obstacle;
process the distance data generated by the collision detection and avoidance system; and
execute a target path for directing the propulsion system to cause the unmanned aerial vehicle to travel around the obstacle and to the at least one other location based at least in part on the flight path and the distance data, the target path configured to maintain at least a minimum overlap between adjacent aerial images captured by the camera to ensure complete coverage of the roof.

10. The unmanned aerial vehicle of claim 9 , wherein the target path is a first target path, and wherein if the collision detection and avoidance system determines that the minimum overlap between adjacent images cannot be maintained by moving the unmanned aerial vehicle closer to the roof, the collision detection and avoidance system is configured to steer the unmanned aerial vehicle to a second target path above both the obstacle and the roof.

11. The unmanned aerial vehicle of claim 9 , wherein the collision detection and avoidance system comprises a camera.

12. The unmanned aerial vehicle of claim 9 , wherein the collision detection and avoidance system is imaging based and the collision detection and avoidance system uses images and auto-aerial triangulation to detect the obstacle for avoidance by the unmanned aerial vehicle.

13. The unmanned aerial vehicle of claim 9 , wherein the one or more processors are configured to process distance data generated by the distance detector during the execution of the target path.

14. The unmanned aerial vehicle of claim 9 , wherein the one or more processors are configured to control the camera to capture image data based at least in part on the location of the unmanned aerial vehicle.

15. The unmanned aerial vehicle of claim 9 , wherein the unmanned aerial vehicle is configured to adjust a flight path for the execution of the target path based at least in part on the detection of the one or more obstacles.

16. The unmanned aerial vehicle of claim 9 , wherein the unmanned aerial vehicle is provided with a gimbal and the camera control information includes gimbal control information configured to align the camera of the unmanned aerial vehicle perpendicular to the roof.

17. A method for collision detection by an unmanned aerial vehicle having a camera to conduct an evaluation of a roof, the method comprising:
receiving a flight path and camera control information, wherein the flight path includes instructions for the unmanned aerial vehicle to travel from a current location to an offset above the roof, the offset being a vertical and lateral offset from the roof, the camera control information including instructions to cause the camera to capture images at a predetermined time interval;
as the unmanned aerial vehicle is flying the flight path, detecting an obstacle for avoidance by the unmanned aerial vehicle based at least in part on the flight path and data collected from a collision detection and avoidance system, the collision detection and avoidance system having at least one sensor;
receiving data generated by the collision detection and avoidance system concerning at least the obstacle for avoidance; and
execute a target path configured to maintain at least a minimum overlap between adjacent aerial images of the roof captured by the camera to ensure complete coverage of the roof.

18. The method of claim 17 , wherein the sensor is oriented in a manner such that the collision detection and avoidance system collects data regarding the obstacle for avoidance.

19. The method of claim 17 , wherein the collision detection and avoidance system comprises a camera.

20. The method of claim 1
