Trying to use this but stuck after exporting from the labeler (guessing that is close source), lots of questions: What do I do with this data exactly? Not really following the instructions from README Do I need a hefty GPU to run this? Doesn't say anything about hardware. What am I going to get as a result? Will it generate a 3d model or "point clouds" ? Do I need multiple inputs (from different angles) through the labeler? What is the depth estimator being used here (this im most interested in especially its able to detect ground from multiple angles) ? Guess I'm just really lost here but super eager to use this. We do have a real world application to use this.
