And, the size of the center hole 21 on the angle dial 2 is proper, so that the side wall of the center hole 21 can not scratch the appearance of the rotary camera assembly 200 when the rotary camera assembly 200 rotates.

The detection apparatus 100 in the present embodiment is briefly described below as a detection method for detecting the rotation angle of the rotary camera assembly 200 of the mobile terminal.
And starting the mobile terminal and entering an angle detection function interface.

Meanwhile, the rotary camera assembly 200 of the mobile terminal is located at an initial position (the "initial position" refers to that the camera on the rotary camera assembly 200 is located at the back of the mobile terminal, and the receiver on the rotary camera assembly 200 is located at the front of the mobile terminal, and the front and the back are opposite to the direction when the mobile terminal is held by hand), and the rotary camera assembly 200 of the mobile terminal passes through the avoidance notch 22 of the angle dial 2 and extends into the central hole 21 of the angle dial 2, at this time, the rotation center of the rotary camera assembly 200 coincides with the center of the central hole 21 of the angle dial 2.
When the rotary camera module 200 is in the above initial position, the upper left edge of the rotary camera module 200 (the edge is the visible edge 201 of the rotary camera module 200) serves as a rotation start point of the rotary camera module 200, and the rotation start point is aligned with the zero graduation mark on the angle dial 2, thereby facilitating the numerical reading of the actual rotation angle.
