scanContextDistance
Distance between scan context descriptors
Description
computes the normalized distance between scan context descriptors. Determine
loop closure candidates using the computed distance.dist
= scanContextDistance(descriptor1
,descriptor2
)
A scan context descriptor is a 2-D global feature descriptor for a point cloud
that can be used to detect loop closures. To extract a scan context descriptor
fro a point cloud, use the scanContextDescriptor
function.

Algorithms
The function computes the distance between scan context descriptors using a modified cosine distance and normalizes it to the range [
0
to1
).
