meshroom.nodes.aliceVision.CameraInit.CameraInit
Category: Sparse Reconstruction
This node describes your dataset. It lists the Viewpoints candidates, the guess about the type of optic, the initial focal length and which images are sharing the same internal camera parameters, as well as potential camera rigs.
When you import new images into Meshroom, this node is automatically configured from the analysis of the images’ metadata. The software can support images without any metadata but it is recommended to have them for robustness.
Metadata
Metadata allow images to be grouped together and provide an initialization of the focal length (in pixel unit). The needed metadata are:
Focal Length: the focal length in mm.
Make & Model: this information allows to convert the focal in mm into a focal length in pixels using an embedded sensor database.
Serial Number: allows to uniquely identify a device so multiple devices with the same Make, Model can be differentiated and their internal parameters are optimized separately (in the photogrammetry case).
