@ -12,11 +12,14 @@ Meshroom also relies on specific files provided with AliceVision.
Provided in AliceVision source tree: {ALICEVISION_REPOSITORY}/src/aliceVision/sensorDB/cameraSensors.db
* voctree (optional): for larger datasets (>200 images), greatly improves image matching performances.
It can be downloaded [here](https://gitlab.com/alicevision/trainedVocabularyTreeData/raw/master/vlfeat_K80L3.SIFT.tree).
* sphere detection model (optional): for the automated sphere detection in stereo photometry.
It can be downloaded [here](https://gitlab.com/alicevision/SphereDetectionModel/-/raw/main/sphereDetection_Mask-RCNN.onnx).
Environment variables must be set for Meshroom to find those files:
