Method and system for automatically tracking and photographing

A system for automatically tracking and photographing, comprising:

• a gimbal camera, having a gimbal, a camera and a controller installed on the gimbal, the gimbal being used for adjusting a rotation angle of the camera;
• and
• a photographing-moving apparatus for placing the gimbal camera, and the photographing-moving apparatus being provided with a steering gear for controlling a heading direction of the photographing-moving apparatus, and a motor for controlling an operating speed of the photographing-moving apparatus;
• wherein the controller comprises:
• a first acquiring unit, for obtaining a yaw axis gimbal angle parameter, and processing an image captured by the camera to obtain a distance parameter;
• a processing unit, for calculating a steering gear rotation angle control parameter according to the yaw axis gimbal angle parameter, and calculating a motor speed control parameter according to the distance parameter;
• a control adjusting unit, for controlling rotation of the gimbal of the gimbal camera according to the yaw axis gimbal angle parameter in order to control rotation of the camera, and controlling rotation of a steering gear installed in the photographing-moving apparatus according to the steering gear rotation angle control parameter, so that the photographing-moving apparatus faces a target, while controlling a rotation speed of the motor installed in the photographing-moving apparatus according to the motor speed control parameter, so as to realize target tracking;
• a first comparison unit, for comparing the distance parameter with a second predetermined distance;
• a second acquiring unit, obtaining the rotation speed of the motor of the photographing-moving apparatus if the distance parameter is smaller than or equal to the second predetermined distance;
• and
• a second comparison unit, for comparing the rotation speed of the motor obtained with a first predetermined rotation speed;
• wherein the control adjusting unit is further used for controlling the motor to stop rotating, if the rotation speed of the motor obtained is smaller than or equal to the first predetermined rotation speed.
