ZED X vs ZED2 performance in point cloud generation

Hardware ZED X
,
1

I am interested in the ZED X camera for a project and would like to clarify these technical points:

  1. 3D position / coordinates
  • Does this remain stable when the camera is mounted on a moving platform (e.g., a moving car, a flying drone) at 80 km/h?
  1. Point cloud accuracy

  • What is the depth/distance accuracy of the point cloud generated by the ZED X (single camera, of course, not double stereo cameras )?

  • Are there any detailed figures or a comparison of this accuracy relative to the ZED 2?

  • Does it allow capturing accurate point clouds for 3D reconstruction when the camera is facing forward, and there is only a single viewpoint, rather than multiple viewpoints?

  1. Impact of motion

  • Does motion (of the camera or the scene) significantly affect the accuracy of the point cloud?

  • Are there any specific recommendations for using the camera in motion (speed limits, settings, best practices) to maintain good accuracy?

Hi @otmanamel
Welcome to the Stereolabs community.

You should select a ZED X camera for this type of application because the Global Shutter sensors of this model guarantee stable images in high dynamic conditions.

What do you mean by “single camera, of course, not double stereo cameras”?
The accuracy information is reported on the datasheet of the cameras.

Setting a multi-camera configuration does not allow you to obtain a more accurate point cloud, but a wider point cloud.

Yes, mostly when using a Rolling Shutter camera as the ZED 2i is.

Consider using a Global Shutter camera (ZED X) with the lowest possible exposure time setting.
