Method and device for generating photogrammetry data

A method for operating an electronic device comprising a processor and an interface and being configured to generate a digital spatial model, the method comprising:

• accessing, via the interface and/or using the processor, digital raw format images captured from a plurality of different relative positions and comprising metadata providing the capturing position and orientation;
• processing, using the processor, the raw format images for generating spatial photogrammetry data, comprising:
• using the processor, generating, first ancillary format images from the raw format images using first sets of conversion parameters;
• using the processor, determining spatial coordinates by triangulation based on the generated first ancillary format images;
• using the processor, generating second ancillary format images from the raw format images using second sets of conversion parameters different from the first sets of conversion parameters;
• and
• using the processor, generating surface color data based on the second ancillary format images;
• generating a digital spatial model based on the spatial coordinates and the surface color data.
