Assignee: DIRECT CURSUS TECHNOLOGY L.L.C
Field: Computer technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 1:
2. The method of claim 1, wherein the method further comprises:
receiving, by the electronic device from the LIDAR sensor, the second 3D point cloud having a plurality of second data points,
a given second data point from the plurality of second data points being (i) representative of respective coordinates in a 3D space and (ii) associated with a respective normal vector from an other plurality of normal vectors;

determining, by the electronic device, an other uncertainty parameter for the given second data point based on:
a normal covariance of the normal vector of the given second data point,
the normal covariance taking into account the measurement error of the LIDAR sensor when determining the respective coordinates of the given second data point, the measurement error of the LIDAR sensor affecting calculation of the normal vector of the given second data point;

in response to the other uncertainty parameter being above a pre-determined threshold, removing, by the electronic device, the given second data point from the second 3D point cloud,
thereby determining a filtered plurality of second data points; and

using, by the electronic device, the filtered plurality of second data points, for merging the first 3D point cloud of the LIDAR sensor with the second 3D point cloud of the LIDAR sensor.
