Camera FOV
Camera Field Of View (FOV) calculation examples.
A common question is what type of resolution a camera will achieve when being flown and whether the resolution is sufficient. Without more information about the camera resolution, lens, height of the camera and desired use for the information, the question can't be answered. For instance, we have some customers that want enough resolution to detect small insects on a leaf while others are more concerned about estimating biomass in a field or identifying areas that need more fertilizer.
With the small point and shoot cameras, the lens assembly is a zoom type where the user can choose wether the camera is shooting wide angle or wants to zoom in to a particular area. Usually, the cameras are flown at wide angle so that the cameras can be flown close to the ground.
Listed below are some pixel spacing calculations for some common cameras.
