Abstract
A calibration method, a calibration device and a calibration system for a handheld gimbal are provided. The method includes steps of: establishing a communication connection between a mobile terminal and the handheld gimbal; controlling the mobile terminal to move along a specified displacement direction, and obtaining a motor current value of the handheld gimbal in real-time through the communication connection when the mobile terminal moves along the specified displacement direction; obtaining a motion path of a specified analog object in a graphical interface, wherein a corresponding relation exists between the motion path and the displacement direction of the mobile terminal; controlling the specified analog object to perform an analog displacement along the motion path corresponding to the specified displacement direction according to a change of the motor current value; and, when the specified analog object reaches a specified location area, indicating that calibration of the handheld gimbal is finished.
