A question about how to get the georeference #98

Closed 9435LV closed 7 months ago

Hello, I greatly admire your ability to do such a great job.

I would like to ask you, if I want to create my own dataset, how do I obtain the georeference parameter in the georeference.yaml. Or rather, can I use Alexa without changing this parameter_ Use reco. launch to run my dataset

Hey, georeference is computed from the GNSS information in the image meta tags. If those are not provided, there is no georeference. There was once a function to provide an external reference through the georeference.yaml, but this is not currently maintained.

It is an honor for you to reply to my message. Do you mean that the #georeference.yaml file cannot truly function in the program? georeference.yaml %YAML:1.0 transformation_w2g: !!opencv-matrix rows: 4 cols: 4 dt: d data: [ 85.147685, 37.630008, -2.445093, 583499.057912, 37.462956, -85.102441, -5.121097, 5806387.668580, -4.303824, 3.698813, -92.951171, 97.517175, 0.0, 0.0, 0.0, 1.0 ]

No, it's something I used during my thesis. It's a feature that might not be present anymore. Georeferencing still works using the exiv tags of the images, but you cannot provide a known georeference through the yaml.

Thank you very much for your answer. It has solved my question and I sincerely appreciate your outstanding work. In addition, the Chinese New Year is approaching, and I wish you a happy new year in advance. :)

Hello, what is the effect of your implementation on your own dataset? Is the performance achieved comparable to the dataset collected by the author?
