I like that it allows you to make custom scripts, as well as import/export files in various formats - which can be useful if working between multiple computers or clients! Sometimes there are problems importing certain types of images into some other programs; this tends to happen when using older versions of Adobe products. When doing research about different approaches to SfM & MVS pipelines, Colmap was one of many tools used by researchers at UCLan who were looking further back than just OpenCV's approach. There really isn't much else out there like Colmap anymore. At least not since we've stopped developing our own toolkit years ago! Using colmapse mapping techniques enabled us to produce better results from very low quality data. We also found 3D modelling easier to create once we had mapped point clouds onto meshes. This made post processing models such as creating animations far.
