[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the object is placed in the center of the upper end of the detection platform by setting the first gyroscope and the second circular arc rotating arm. When side detection is required, the second servo motor drives the second rotating shaft to rotate, and the second rotating shaft drives the second circular arc rotating arm to rotate to a horizontal position. The object is subjected to single-sided visual detection by the adaptively adjusting camera on the second circular arc rotating arm. When continuous differential detection of the side is required, the first rotating shaft is driven to rotate by the first servo motor, and the first rotating shaft drives the first circular arc rotating arm to rotate, so that the lower end of the first circular arc rotating arm drives the second circular arc rotating arm to rotate in a circle, and the object is continuously photographed and detected at equal time intervals by the adaptively adjusting camera on the second circular arc rotating arm.

Through the arc structure of the second circular arc rotating arm, the first rotating shaft drives the first circular arc rotating arm to rotate. When the first circular arc rotating arm drives the second circular arc rotating arm to rotate, the adaptive adjustment camera on the second circular arc rotating arm makes a circular motion, thereby ensuring the position accuracy of the adaptive adjustment camera during continuous shooting.

[0015] 3. In the utility model, through the setting of the second gyroscope, one end of the second rotating shaft passes through the lower end of the second circular arc rotating arm and is fixedly connected to the second gyroscope. When the second rotating shaft rotates, the rotation angle is recorded by the second gyroscope.
