Is LiDARTag used in it? #17

Closed yanliang-wang closed 3 years ago

yanliang-wang commented 3 years ago

Hi, thanks for your share of this work.

I tried this repository before. The README of this repository and the paper of LiDARTag say that LiDARTag is used in the calibration tool. But I didn't find the LiDARTag detection module in it. So is LiDARTag used in it? Can you point out the use if it is used?

Thank you again.

Hi,

Thanks for being interested in this package.

LiDARTag is only used for extracting the LiDAR returns on a target. After we extract the LiDAR returns, we then use this package to estimated the vertices.

Please let me know if you have further questions!

Hi, thanks for your reply. Specifically, I wonder whether LiDARTag detection module is in this repository.

Hi,

Unfortunately, no.

This repo is matlab-based and LiDARTag is coded in C++. Please refer to LiDARTag for more details.

Hi,

Ok, I got it.

Thanks for your reply again. This work and LiDARTag are really nice.
