mrpt::math::CAtan2LookUpTableMultiRes Class Reference

Detailed Description

Like CAtan2LookUpTable but with a multiresolution grid for increasingly better accuracy in points nearer to the origin.

Example of usage:

std::map<double,double> res2extension;
res2extension[0.001] = 0.5; // 0.1 cm resolution up to 0.5 m
res2extension[0.01] = 1.0; // 1 cm resolution up to 1 m
res2extension[0.02] = 3.0; // 2 cm resolution up to 3 m
res2extension[0.05] = 7.5; // 5 cm resolution up to 7.5 m
res2extension[0.10] = 12.0; // 10 cm resolution up to 12 m
atan2lut.resize(res2extension);
