we are using ZED 2i to do localization, we have run position tracking sample of ZED, and make changes in it to save area map in order to improve localization precision as well, we found it is difficult to local the zed camera in area map even in a small room. Do we have any advice to improve the localization with area map? i see in other topic, it mentioned we can use tag (apriltag or other tag family) to improve localization precision, but have to use ros. Do we have sample code with tag, but no ros?
Hi Myzhar, Thanks for your reply, i have checked that sample which helps a lot. BTW we found we have a sample named global localization, which apply zed and GNSS/RTK, we can only use GNSS in our case, even RTK is more accurate. Can you explain if combining zed camera and GNSS could improve localization accuracy? and what accuracy can be achieved?
Thank you
Hi Myzhar,
In our scenario, RTK is not available ,we can only use GNSS, We want to achieve precise localization within a one-kilometer range outdoors. Assuming our GNSS accuracy is in 3 to 5 meters, what around accuracy we can expect if we combine GNSS and ZED camera?
Thank you
Hi @phenixyu
in this case the GNSS fix is not useful because it provides an information that is less accurate than the information provided by the SDK.
It can help reducing the drift, but the only if the trajectory is very long.
It’s not possible to provide a precise estimation of the final accuracy because it strongly depends on the structure of the environment.
