Calibration method, calibration device and calibration system for handheld gimbal

A calibration device for a handheld gimbal, comprising:

• a communication connection module, which is configured to establish a communication connection between a mobile terminal and the handheld gimbal, wherein the mobile terminal is located on the handheld gimbal and shooting of the mobile terminal is controlled by the handheld gimbal;
• a first motor current value obtaining module, which is configured to control the mobile terminal to perform a displacement motion along a specified displacement direction and obtain a first motor current value of the handheld gimbal in real-time through the communication connection when the mobile terminal performs the displacement motion along the specified displacement direction;
• an analog object motion path obtaining module, which is configured to obtain a specified motion path of a specified analog object in a predetermined first graphical interface and a corresponding relation between the specified motion path and the specified displacement direction;
• an analog object analog displacement module, which is configured to control 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 first motor current value;
• and
• a calibration result indicating module, which is configured to indicate that calibration of the handheld gimbal is finished when the specified analog object reaches a specified first location area;
• wherein:
• the communication connection in the communication connection module comprises a wired connection, a Bluetooth communication connection, a wireless internet communication connection and an infrared communication connection;
• the calibration device further comprises a balancing weight position/size adjusting module, which is configured to adjust a position/size of a balancing weight of the handheld gimbal, and obtain a second motor current value of the handheld gimbal in real-time through the communication connection when the position/size of the balancing weight changes;
• the analog object motion path obtaining module is further configured to obtain a third motion path of a specified third analog object in a predetermined second graphic interface;
• the analog object analog displacement module is further configured to control the third analog object to perform an analog displacement along the third motion path according to a change of the second motor current value;
• and
• the calibration result indicating module is further configured to indicate that the calibration of the handheld gimbal is finished when the third analog object reaches a specified second location area.
