This is of course until you get to the high end scanners like the one linked here which use one or more high resolution LIDAR sensors in conjunction with cameras, lights, motion sensors, etc: alll selected and calibrated to give precision results.

Nearly every technique I have tried or seen produces a much lower quality result than the above, costs a lot more, or has some other limitation (such as the size of the object you can scan) that radically limit its usefulness. There are alternative workflows and 'low cost' commercial hardware and software products even for photogrammetry in the market.

But it's the right direction to explore right now. That's not to say there isn't a knack to it or things you have to learn.

This works for really tiny stuff right up through drones scanning entire buildings, and the workflow is the same. At the hobbyist level currently the best results (in terms of cost/quality and time/quality and overall capability) can be achieved using photogrammetry in conjunction with processing in Meshroom and post processing in Meshlab or Blender or editor of your own selection.
