How to Check Mapping Accuracy #28

Closed jeychandar closed 11 months ago

jeychandar commented 1 year ago

@rsasaki0109 Hi Sir. Since you have working with mapping related field, I am curious to know about the mapping accuracy. Could you guide me how to check mapping accuracy sir. Thanks in advance.

Is it something like comparing with RTK GNSS/IMU? I think the following link may be of reference. https://github.com/autowarefoundation/autoware-documentation/pull/366 https://autowarefoundation.github.io/autoware-documentation/pr-366/how-to-guides/creating-maps-for-autoware/open-source-slam/compare-slam-algorithms/

We would like to check the 3D LiDAR mapping accuracy for indoor settings. Eventually the mapped scans will be compared against building information models (e.g. construction progress monitoring & verification).

rsasaki0109 commented 1 year ago

For indoor references, tracking is often done with total stations. Additionally, for map evaluation, comparisons can be made with floor plans or maps created with ground-based laser scanners.

Okey sir will check it out
