While our sensors have been developed for use on an aerial platform such as a multi-rotor drone or fixed-wing aircraft, some researchers have used MicaSense sensors at much lower altitudes for time lapse or single capture analysis.
The camera has a fixed-focus set to be focused at infinity; objects will be in varying degrees of focus at 1-2 meters. Since the camera has five independent lenses and imagers, the images are taken from slightly different locations. Images taken closer than 15 meters will generally have parallax errors due to these slight location differences that may result in processing artifacts and a lack of sufficient texture to combine into an orthomosaic. The same is true if you were to attempt to align the bands of an individual image.
MicaSense encourages capturing at 15 meters or higher but in some instances capturing data at lower height can still be of good quality. We recommend experimenting to find the altitude that works best for your use case.
Depending on the height of the object being imaged, single captures can be aligned and analyzed using the MicaSense image processing library. For example, you may be able to analyze a capture from 15 meters if the surface is flat, but if the frame is composed of a 10-meter tree canopy, you will have trouble aligning the bands.
