Question about nuscenes camera2lidar extrinsic #79

Open lucianzhong opened 1 year ago

lucianzhong commented 1 year ago

For one scenario in nuscenes dataset, take 61 as example, the sensor2lidar_translation between CAM_FRONT and lidar_top differs from one timestamp to another timestamp. such as: [-0.01613824 0.43552529 -0.32067179], [-0.00871988 0.5708719 -0.31998898] 0.5708719 - 0.43552529 = 0.13, the y direction of translation is the vehicle's forward direction. From my opinion,the extrinsic should ideally remain constant or minor variation. Could someone give explanation?

Best regards
