System and method for tracking targets

A tracking system configured to track a movement of a target, the tracking system comprising:

• a memory storing executable instructions;
• a camera configured to acquire image data of the target;
• and
• at least one processor configured to execute the stored instructions to:
• determine a distance between the target and an unmanned aerial vehicle carrying the tracking system;
• determine, from the image data, two-dimensional pixel coordinate data associated with a plurality of features of the target;
• determine a physical dimension based on the two-dimensional pixel coordinate data and the distance;
• and
• determine, based on the physical dimension and at least one of the two-dimensional pixel coordinate data or the distance, three-dimensional location coordinate data of the target with respect to the UAV.

A movable object, comprising:

• one or more propellers;
• one or more sensors configured to obtain speed and direction information of the movable object;
• a camera configured to acquire image data of a target;
• a radio communication system configured to receive signals from a satellite navigation system;
• and
• a controller comprising:
• a memory storing executable instructions;
• a camera configured to acquire image data of the target;
• and
• at least one processor configured to execute the stored instructions to:
• determine a distance between the target and the movable object based on the signals received from the radio communications system,
• determine, from the image data, two-dimensional pixel coordinate data associated with a plurality of features of the target,
• determine a physical dimension based on the two-dimensional pixel coordinate data and the distance,
• determine, based on the physical dimension and at least one of the two-dimensional pixel coordinate data or the distance, three-dimensional location coordinate data of the target with respect to the mobile object, and
• control the one more propellers based on the three-dimensional location coordinate data, and the speed and direction information of the movable object.
