Find k1,k2,k3 in intrinsics, but not used in api #219

In intrinsics.feather , I can see k1 k2 and k3. I think they should be used for calibration, but they are not used in the api. I wonder the reason. Is this because you have used them to tune the images, so it is no need to use them again?

Hi @zzj403,

k1-k3 are the radial distortion coefficients. The images provided in the dataset have already been undistorted, so they are not used in the API.

Hope this helps,

Ben
