Abstract
In one example, a method may include receiving one or more laser scan of a scene, receiving two or more camera images of the scene, determining one or more decision regions where the camera images are different from one another, detecting edges of the decision regions where the camera images are different from one another, comparing the decision regions where the camera images are different from one another inside of the detected edges with a corresponding region in the laser scan to determine which of the camera images includes a desired region that more closely corresponds to the laser scan, and generating a corrected image including the desired region that more closely corresponds to the laser scan.
Claims20
A method comprising:
- receiving one or more laser scan of a scene, the laser scan including a three-dimensional point cloud of the scene;
- receiving two or more camera images of the scene, wherein the camera images are taken at different times from one another;
- determining one or more decision regions where the camera images are different from one another;
- detecting edges in the decision regions where the camera images are different from one another;
- comparing the decision regions where the camera images are different from one another with a corresponding region in the laser scan to determine, using the detected edges, which of the camera images includes a desired region that more closely corresponds to the laser scan;
- and
- generating a corrected image including the desired region that more closely corresponds to the laser scan.
