Yes. The problem of SLAM from LIDAR, GPS / IMU data (which are cheap sensors), and pre-recorded maps was solved years ago.

- kristoffer 10y agoYou can do SLAM with only cameras ...
- argonaut 10y agoNo you can't. Have you tried it? Firstly, the state of the art (which is not deep learning based) still has trouble when the camera doesn't turn/swivel a lot (e.g. it has trouble when the camera is just moving straight). And that's not even getting to the most critical assumption. All of visual SLAM right now assumes the environment is static (!!!), and doesn't work when things in the environment are allowed to move.
- blt 10y agoIn my opinion, a system that combines LIDAR, GPS, and a pre-recorded map is not really doing SLAM. This scenario does not suffer from the "chicken and egg" problem which is a defining characteristic of SLAM. GPS and the pre-recorded map both make the problem much, much easier than SLAM in a GPS-denied, unmapped area. Maybe we are just arguing over terminology.
- argonaut 10y agoWe are. SLAM, LAM, same thing as far as building a 3d model of your environment is concerned.
