The present invention provides systems, methods, and devices related to target tracking by UAVs. The UAV may be configured to receive target information from a control terminal related to a target to be tracked by an imaging device coupled to the UAV. The target information may be used by the UAV to automatically track the target so as to maintain predetermined position and/or size of the target within one or more images captured by the imaging device. The control terminal may be configured to display images from the imaging device as well as allowing user input related to the target information.
