Abstract
A method for image generation, preferably including: generating a set of mission parameters for a UAV mission of the UAV associated with aerial scanning of a region of interest; controlling the UAV to perform the mission; generating an image subassembly corresponding to the mission; and/or rendering the image subassembly at a display.
Claims18
A system comprising:
- a mobile user device communicatively connected to a camera and configured to receive images of a geographic region from the camera, the mobile device comprising a memory and a processor, wherein the processor is configured to:
- determine a set of features for each of the images;
- determine a temporal window of images corresponding to a limited number of the images which are most recently captured or processed, wherein the temporal window of images are captured by the camera and stored at the memory of the mobile user device;
- and
- based on the temporal window, determine a refined camera pose associated with the image and a set of feature positions, comprising:
- for each feature of the set of features, determining a set of matches within the temporal window of images;
- based on the set of matches, determining a set of estimated positions;
- and
- performing a bundle adjustment to refine the set of estimated positions using only images within the temporal window of images to reduce processing requirements of the processor.

A method comprising:
- at a mobile user device, receiving an image from a camera at a receipt time;
- determining a set of features based on the image;
- determining a temporal window of aerial images corresponding to a limited number of the images which are most recently captured or processed within a set of historical images from the camera stored at the mobile user device;
- for each feature of the set of features, determining a set of matches within the temporal window of aerial images,
- determining a set of feature positions for each feature of the set of features;
- at the mobile user device, generating an orthomosaic image based on the set of feature positions;
- and
- at the mobile user device, displaying the orthomosaic image in real time relative to the receipt time.
