Systems and methods for adaptive scanning based on calculated shadows
An unmanned aerial vehicle (UAV) assessment and reporting system may utilize one or more scanning techniques to provide useful assessments and/or reports for structures and other objects. The scanning techniques may be performed in sequence and optionally used to further fine tune each subsequent scan. The system may include shadow elimination, annotation, and/or reduction for the UAV itself and/or other objects. A UAV may be used to determine a pitch of roof of a structure. The pitch of the roof may be used to fine tune subsequent scanning and data capture.
1. An unmanned aerial vehicle (UAV) assessment system for imaging a structure, comprising:
a site selection user interface to receive an electronic input from a user identifying a location of a structure; and
a UAV to receive the location of the structure from the site selection interface, the UAV comprising:
a camera to capture images of a roof of the structure;
a proximate object determination system to identify at least one object proximate the roof of the structure; and
a shadow determination system to calculate a location of a shadow cast by the proximate object onto the structure based on a location of the sun at one or more times;
an imaging system to account for the calculated shadow by annotating images of the structure captured by the camera that are calculated to include the shadow.
2. The UAV assessment system of claim 1 , wherein the imaging system is part of the UAV, and wherein the imaging system is configured to account for the shadow in real-time during imaging by annotating images of the structure that include the calculated shadow at the one or more times.
3. The UAV assessment system of claim 1 , wherein the imaging system is integrated within the UAV.
4. The UAV assessment system of claim 1 , wherein the site selection user interface and the imaging system are embodied within one of mobile phone, a personal computer, and a tablet device.
5. The UAV assessment system of claim 1 , further comprising:
a processor; and
a non-transitory computer-readable medium for receiving and storing instructions that, when executed by the processor, cause the UAV to conduct a structural damage assessment, including:
a boustrophedonic scan of the site containing the structure, the boustrophedonic scan comprising a sequence of images captured during a boustrophedonic flight pattern within a first altitude range; and
a micro scan of the structure in a second flight pattern that includes vertical approaches proximate the structure to capture detail images of the structure.
6. The UAV assessment system of claim 1 , wherein the camera is configured to capture images of a roof of the structure with an optical axis of the camera aligned perpendicular to the plane of the roof of the structure by adjusting at least a tilt angle of the camera of the UAV.
7. The UAV assessment system of claim 1 , wherein the object comprises a tree.
8. The UAV assessment system of claim 1 , wherein the object comprises one of: a chimney and a skylight.
9. The UAV assessment system of claim 1 , wherein the object comprises one of: a power line, a power pole, a tree, and a neighboring structure.
10. The UAV assessment system of claim 1 , wherein the camera comprises at least one of an infrared camera, a visible-light camera, and an ultraviolet camera; and wherein the shadow comprises one of an infrared shadow, a visible-light shadow, and an ultraviolet shadow.
11. The UAV assessment system of claim 1 , further comprising:
a pitch determination system to determine a pitch of a planar surface of the roof that is at an angle relative to a downward direction based on at least two distance measurements.
12. The UAV assessment system of claim 11 , wherein the shadow determination system is further configured to calculate the location of a shadow cast by the proximate object onto the structure based on the determined pitch of the planar surface of the roof.
