I just found a lidar app and used it to make an importable background for a floor plan. The result is absolutely amazing. It does require a smart phone with lidar. I have an iPhone 12 Pro. The specific app I used is called Polycam. I'm sure there are others. That's the only one I've tried.
The mapping process is incredibly quick. You basically just hit the start button and then film the area you want to map. It shows you what's done by displaying the unmapped area with a blue tint and the mapped area as normal. A typical kitchen or dining room would take around 2 minutes to map. Maybe even less. It processes the data in a couple of minutes and voila.
There's no faster way I can think of that you could get a detailed floor plan of an area that has a perfect overhead vantage point even higher than the ceiling of a space allows. Shot Designer seems to make the animations just the right size, too. The combo is an incredibly powerful tool.
It's also quite accurate. I saw someone report they had only a 20cm variance over a 60m distance. I think that's astonishing. It will automatically show you all the measurements of the floor plan if you want, too. For my American friends you can easily switch to Imperial.
I've included a couple of quick samples that took me maybe 10 minutes total. I hope you find this useful.
