Abstract

The invention discloses a holder servo system of a vehicle-mounted camera and a control method thereof. The servo system comprises a camera three-axis holder and a servo control device. The camera three-axis holder consists of a pitching motor, a side-tipping motor, a yawing motor, a side-tipping arm (1), a pitching arm (4), a yawing arm (5), a holder top seat (7), a camera (11), a pitching shaftbearing (12) and a balancing weight (13). The pitching motor includes a pitching motor stator (2) and a pitching motor rotor (3). The yawing motor includes a yawing motor stator (6) and a yawing motorrotor (8). The side-tipping motor consists of a side-tipping motor stator (9) and a side-tipping motor rotor (10). The servo control device comprises an inertia measurement unit, a three-dimensionalmodeling control unit, an angular velocity loop control unit and an angular displacement loop control unit. Therefore, the dynamic performance and the anti-interference performance of real-time control of the camera three-axis holder servo system are improved and the safety of unmanned vehicles is guaranteed.

Description

technical field [0001] The invention relates to a vehicle-mounted camera, in particular to a vehicle-mounted camera pan-tilt servo system and a control method. Background technique [0002] The safety of unmanned vehicles has always been a hot issue in this field, and cameras as visual sensors provide a large amount of data information for unmanned vehicles. However, due to factors such as uneven road surface, steering, braking, and acceleration, there are various uncertain attitude changes of the vehicle in actual driving, which constitute the disturbance factor of the camera operation. In order to ensure the stability and continuity of the video data, the three-axis gimbal of the vehicle camera came into being, which is a three-axis rotatable mechanical structure. Different from cameras in drone aerial photography and handheld shooting, unmanned driving cameras are the key equipment to realize unmanned driving functions. Therefore, improving the stability of the camera's ...
