Hi there .... Did you manage to find suitable software? I am also in the market for softwareI have a job to count the number of animals on a game farm. The farm is 10 square miles in area. Is there software that will assist me with this project.
Not sure on software but I would think a thermal camera would work best to pick out the animals. A low tech solution cold be a cheap iPhone with a plug in Flir camera, set camera to time laps to get a good overlap and get the images laces together. If the phone stored gps locations for every picture would be grate or a camera that had gps would be ideal. The thermal pics are low low res so you wouldn’t have to worry about taking to many. Good luck
