Cesium does not support loading oblique photography OSGB data directly:

However, OSGB data can be converted into a format that Cesium can load.
Currently, the best-supported format defined by Cesium is 3D Tiles. This format is still evolving and not yet fully mature, but based on official demos, the results are quite impressive.
3D Tiles adds FeatureTable and BatchTable at the logical (JSON) layer, as well as the LOD (tileset) concept, with corresponding binary storage headers. From a data specification perspective, it inherits the excellent parts of glTF while also considering oblique photography and point clouds. Support for OSM is planned for the future, providing good coverage of data types.
3D Tiles = glTF + LOD

During development, I found some conversion tools shared by developers online:

After testing, I found that:

After downloading the conversion tool, there is an operation example image included in the directory. Feel free to leave a comment if you have any questions.
