Sorry, Too little experience with it. The experts here should advise you.No never used both of them. It is my very first topo-project.
Are the trials fully operational, or are there restrictions ? Which is best ?
I am also using the H520 with E90, amongst other cameras.It is indeed basically 2D ... Need to make one big 'foto' of an area with all the trees visible. 3D would be nice, but not necessary ... It is a terrain that would be filled up with sand-waste, and whom all surrounding habitants are 'against'. Terrain-surface is approximatly 1 by 1 km ... At 45 meters height and at 3m/second it will be +- 452 pictures (datapilot-estimation 30% font/back and left/right) that will need to be stiched. Do you have an idea of such a free software ? I will be flying a H520 with a E90-camera.
It does this automatically, based upon the GPS-coördinates an route of the drone (compass) included in the JPEGS ? Or, do one have to stich and rotate hem yourself ?
30% is not enough. See Pix4D recommended overlaps attached.Thx for the tip, will try that ... But first need to accomplish mission
Will 30% front/back/left/right be enough at an altitude of 45m and at a speed of 3m / sec .
