About calibrated_sensor.json coordinate system #944

Closed SeungHwi0613 closed 1 year ago

SeungHwi0613 commented 1 year ago

Hi, I have one question about 'calibrated_sensor.json' file.

Where is sensor's translation coordinate system's origin point? I can see Y-axis is same with LIDAR. But Z and X is not zero. (I guess Z is based on ground) So i want to know the coordinate system of translation in this file.

If you give me some illustration to make it clear, would be so nice!

Thanks.
