iOS and Android users with LiDAR or ToF sensors in their devices can use the Live Preview feature to gain insight into what is being captured.

Important: Preview is not the final result; data must be post-processed in Pix4D Desktop applications (e.g., PIX4Dmatic or PIX4Dmapper) or PIX4Dcloud once capturing is finished.
  • Map_view.png   Top view: Full view of the project area.
  • POV_view.png   First-person view: Focused view from the camera perspective.

Image Trigger Method

Toggle between Device Pose or Image Overlap to select the image trigger method for capture. Only one of the 2 methods can be active. The default triggering method is Image Overlap.
