A visual target is not necessary but the Spark does have a Precision Landing feature where the AC automatically scans and attempts to match the terrain features underneath during landing after RTH. For this feature to work, the AC must take off vertically straight to a height of minimum 7 meters, whereby the AC maps the terrain underneath with the help of the bottom camera. Needless to say, good lighting conditions and distinct terrain features are essential for this feature to work efficiently. It is not as advanced as the 3D mapping technology available in the Mavics but works pretty well when you are using a landing pad and wish the AC to land autonomously on it.
