AI Technical Summary
Traditional visual inertial systems have limited field of view and active perception capabilities, especially due to the limitations of camera field of view and lack of active perception capabilities.
Design a visual radar device, in which a camera module, a camera control module, and an inertial measurement module are respectively mounted on a base, and the camera control module is connected to the inertial measurement module. A miniature slip ring and a miniature hollow DC brushless motor are used to ensure the continuous rotation of the camera, and the control is combined with encoder information to achieve separation of the camera and the inertial measurement module.
It improves the field of view and active perception capability of the visual inertial system, reduces the dynamic response error of the IMU, and enhances the dynamic response accuracy of the SLAM algorithm.
