Quantization in poses using GPS / INS data #87

Open MohrMa2 opened 5 years ago

MohrMa2 commented 5 years ago

When I plot the output from data/poses.txt, columns 11-13 I see a "quantization" effect for latitude and longitude. matlab

The effect for longitude is smaller but can be seen from the data: poses.txt

The original drive does not have this effect: gps

Does this come from using float for Lat and Long? Will it have an influence on the final calculation?
