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.
Claims20
A method comprising:
- controlling an aircraft within a geographic region comprising:
- at a camera of the aircraft, capturing an image of the geographic region;
- concurrently with controlling the aircraft, at a user device:
- determining a set of features for the image;
- determining a terrain homogeneity score based on the size of the set of features;
- determining a window of images, within a set of previous images of the geographic region, based on the terrain homogeneity score, wherein the set of previous images are captured by the aircraft;
- based on the window, determining 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 window of previous 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.

A method comprising:
- at a user device, receiving an aerial image from an aircraft at a receipt time;
- determining a set of features based on the aerial image;
- determining a sliding window of aerial images within a set of historical aerial images from the aircraft stored at the user device, wherein the sliding window comprises a number of images restricted based on:
- a device processing requirement and a terrain homogeneity score;
- for each feature of the set of features, determining a set of matches within the sliding window of aerial images;
- determining a set of feature positions for each feature of the set of features;
- generating an orthomosaic map based on the set of feature positions;
- and
- at the user device, displaying the orthomosaic map in real time relative to the receipt time.
