Therefore, tunnel survey camera devices have become a hot spot in the development of rail transit application equipment. Ordinary cameras on the market always have blind spots and are difficult to cooperate with tunnel inspection robots, which causes the camera to shake easily and change its position and angle during tunnel inspection, reducing the working stability of the camera.

[0006] In a preferred example, the present application can be further configured as follows: a first brushless motor is provided at the connection between the stability ball frame and the rotating sphere, and the first brushless motor is used to drive the rotating sphere to rotate.
[0007] In a preferred example, the present application can be further configured as follows: an acceleration sensor, a gyro effect sensor and a magnetometer sensor are installed on the surface of the stability ball frame, the acceleration sensor is used to detect the rotation speed of the first brushless motor, the gyro effect sensor is used to measure the angular velocity, and the magnetometer sensor is used to detect the magnetic field strength.

The stability ball frame has three built-in sensors, namely the acceleration sensor, which mainly detects the information of the rotation speed of all the bearings equipped with the first brushless motor, the gyro effect sensor, which helps the inertial measurement unit to understand which brushless motor is rotating and measure the angular velocity, so as to adjust the angle, and the magnetometer sensor is used to detect the magnetic field strength. The combination of the three sensors greatly improves the stability of the tunnel inspection camera during the shooting process.
