Why don't you use the 5 second time lapse photo option? You can calculate the ideal horizontal speed to obtain the ~70-80% overlap and not have to worry at all about pushing the capture button sporadically. The image sensor on the camera is ~3000x4000. If your desired GSD (Ground Sample distance) is say 1" (2.54 cm) then each image is ~250' (3000/12) Tall by 333.3' (4000/12) wide. So to obtain ~80% overlap means ~50 ft of new area is added and 200 feet was duplicated from the previous image. If the image is taken every 5 seconds, you have 5 seconds to fly 50' or 10' per second. You maintain a consistent Horizontal speed and you can easily capture what is needed with out any guessing or Sporadicness. |
