I am new to Pix4D and a rookie in the field of georeferencing and GIS, and I have some questions about the possibilities of the PIX4D software:
We are using a DJI phantom pro 4 V2 drone and fly it over sea, recording video footage which we want to use for photogrammetry. To have higher accuracy of altitude, we use a laser that records the altitude and will not be using the altitude recorded by the drone.
My aim is to georeference snapshots from the videos and correct for the gimball angle and altitude (to be able to get accurate measurements of any objects that were filmed), using the known altitude and known gimbal settings.
My questions are:
- Can I use Pix4D mapper to convert the images to georeferenced files (i.e. TIFF) and use the gimbal settings (etc) from the flight log data of my drone to correct for the camera angles deviating from zero?
- If this is possible; Can I use the altitude recorded by our laser, or can I only work with the altitude recorded by our drone?
