Kalibr imu. еЏ‚иЂѓпјљ ж­¤иї‡зЁ‹жЉҐй”™пјљNO module named scipy.

Kalibr imu. The camera system is fixed and the calibration target is moved in front of the cameras to obtain the calibration images. In addition, it allows for estimating IMU intrinsics as well as the displacement of the accelerometer y- and z-axis with respect to its x-axis. Due to competing objectives-either desired vicinity to the center of gravity when used in controls, or an unobstructed field of view when integrated in a sensor setup with an exteroceptive sensor for ego-motion estimation-individual IMUs are often mounted at considerable distance. The camera-imu calibration tool estimates the spatial and temporal parameters of a camera system with respect to an intrinsically calibrated IMU. kalibr_calibrate_imu_camera --bag MYROSBAG. еЌ•з›®+IMU е’Њ еЏЊз›®+IMU дёєдѕ‹пјЊи®Іи§ЈдЅїз”Ё Kalibrе·Ґе…· ж ‡е®љ Camera-IMU，其中使用的摄像头分别为 Realsense ZR300 е’Њ MYNT-EYE S系列摄像头。 2. и‡ідєЋдёєд»Ђд№€еЏ«kalibrпјљиї™дёЄе·Ґе…·з®±з”±ETHZе€›е»єпјЊењЁз‘ћеЈ«еѕ·иЇ­ж�Їдё»и¦ЃиЇ­иЁЂпјЊиЂЊcalibrationзљ„еѕ·ж–‡ж�ЇKalibrierungпјЊиї™еє”иЇҐж�ЇKalibrиї™дёЄproject名称的由来。 Nov 11, 2018 В· Hi !
