I will be receiving drone images from an associate. It'll have longitudes/latitudes values from the corners of the image. I don't have access to his image processing S/W. It'll be in a relatively small area 1,000,000m². Not sure if I would need the accuracy of something like the Haversine formula.
I need to find the coordinates (longitude, latitude) of a given point (trucks for example) in the image. This point is ever changing image to image. I'm seeking an equation/Java code/Python code etc.
