A high overlap between images is required to automatically get accurate results. Carefully design your image acquisition plan to ensure enough overlap.

Consider the following when you design your image acquisition plan:

  • Plan for desired GSD, RTK GPS on the aircraft, or for GCPs can provide better position accuracy than standard GPS, depending on conditions.
  • Avoid high winds or moving clouds.
  • Avoid homogenous environments such as sand, coal or, snow (increase altitude and overlap if needed).
  • Avoid dynamic scenes if possible (water, moving trees, moving vehicles, or similar subjects).
  • Increase overlap if scene must be dynamic.
  • Set white balance and exposure appropriate for conditions. Take test photos first to ensure no over/under exposure.
  • If there are tall buildings, plan for the GSD at the roof, and add in additional flight lines to cover the ground

A bad image acquisition plan leads to inaccurate results or processing failure. You’ll need to acquire images again.

Advanced UAVs come with software to design the image acquisition plan given parameters (area of interest, the percentage of overlap between the images, the desired GSD, and so on). The UAV automatically takes the images according to the selected image acquisition plan without user intervention.

The design of the image acquisition plan consists of three steps:

  1. Select the Image Acquisition Plan Type.
  2. Compute the Flight Height for a given GSD.
  3. Compute the Image Rate for a given Frontal Overlap.
