AI Technical Summary
Existing spatial distance perception methods, such as terrain rendering and grid lines, cannot provide accurate spatial distance indications, causing pilots to be unable to obtain the distance values between targets and the aircraft's current position, thus affecting flight safety.
By acquiring terrain elevation data of the aircraft's location, the coordinate data of the sampling points are calculated using the WGS84 coordinate system to ECEF coordinate system transformation algorithm, and a distance ring relative to the aircraft's preset distance is drawn using the triangle centroid interpolation algorithm to provide intuitive distance indication.
It enhances the pilot's distance perception of the external flight environment, improves flight safety, and ensures that the pilot can clearly recognize the actual distance between key targets and the aircraft.
