Patent number: 10853931Abstract: An automated image capturing and processing system and method may allow a field user to operate a UAV via a mobile computing device to capture images of a structure area of interest (AOI). The mobile computing device receives user and/or third party data and creates UAV control data and a flight plan. The mobile computing device executes a flight plan by issuing commands to the UAV's flight and camera controller that allows for complete coverage of the structure AOI. After data acquisition, the mobile computing device then transmits the UAV output data to a server for further processing. At the server, the UAV output data can be used for a three-dimensional reconstruction process. The server then generates a vector model from the images that precisely represents the dimensions of the structure. The server can then generate a report for inspection and construction estimation.Type: GrantFiled: January 11, 2019Date of Patent: December 1, 2020Assignee: EZ3D TECHNOLOGIES, INC.Inventors: Martin Marra, James F.
