Embodiment Construction
[0022] The basic principle of the gimbal control method based on the mobile phone and the built-in gravity sensor is: the current smart phone has a built-in gravity sensor, which can perceive the projection on each component (X, Y, Z axis) of the space when the mobile phone moves in the three-dimensional space. value. And the user holds the mobile phone in a natural posture (the natural posture refers to the mobile phone screen facing the user, and the body has an inclination angle of 15° to 75° from the ground level), and when the mobile phone is turned left and right, up and down, the acceleration of gravity on each component of space Projected values can reflect such rotational motion. According to this, the mobile phone body can be simulated as a remote gimbal, and by recording the rotation of the mobile phone body in the horizontal and vertical directions, the user's control requirements for the remote gimbal can be sensed, and the control requirements can be converted ...
