SYSTEMS AND METHODS FOR LOW-COST HEIGHT ABOVE GROUND LEVEL AND TERRAIN DATA GENERATION

This abstract first appeared for US patent application 18404654 titled 'SYSTEMS AND METHODS FOR LOW-COST HEIGHT ABOVE GROUND LEVEL AND TERRAIN DATA GENERATION

Original Abstract Submitted

Systems and methods for low-cost HAGL measurement and terrain database updates are provided. In one example, a system includes an image capturing device configured to capture first and second images and a navigation system configured to generate pose data. The system further includes processor(s) communicatively coupled to the image capturing device and the navigation system and a non-transitory, computer-readable medium communicatively coupled to the processor(s) that stores instruction(s) which, when executed by the processor(s), cause the processor(s) to: estimate optical flow between the first and second images; determine rigid flow per image for each depth bin of a group of depth bins based on the pose data, wherein each depth bin corresponds to a particular depth range; and generate a dense depth map by determining a depth bin, for each pixel, that minimizes a difference between the estimated optical flow and the determined rigid flow for the respective pixel.
