Title:
VEHICLE-MOUNTED CAMERA GIMBAL SERVO SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/098238
Kind Code:
A1
Abstract:
A vehicle-mounted camera gimbal servo system and a control method. The vehicle-mounted camera gimbal servo system comprises a three-axis camera gimbal and a servo control device. The three-axis camera gimbal comprises a pitch motor, a roll motor, a yaw motor, a roll arm (1), a pitch arm (4), a yaw arm (5), a gimbal top base (7), a camera (11), a pitch shaft bearing (12) and a counterweight block (13). The pitch motor comprises a pitch motor stator (2) and a pitch motor rotor (3). The yaw motor comprises a yaw motor stator (6) and a yaw motor rotor (8). The roll motor comprises a roll motor stator (9) and a roll motor rotor (10). The servo control device comprises an inertial measurement unit, a three-dimensional modeling control unit, an angular velocity loop control unit and an angular displacement loop control unit. The invention improves dynamic performance and interference resistance of of real-time control performed by a three-axis camera gimbal servo system, thereby guaranteeing safety of an autonomous vehicle.
