If I have a piece of wood like the above in my backyard, I wonder how I can turn it into a digital asset, the model with all kinds of texture maps including roughness map, UV map, and so on, so that I can save it locally or upload into a digital asset website like Poliigon, I hope I’ve made me clear, thanks!
I’d say that’s quite the project if you don’t already know how such things work.
I’m not sure if this step is required, but I think you might want to use a 3D-scanner to get an accurate model of the piece of wood. These can be quite expensive and if you want a high quality model you probably shouldn’t cheap out on it.
Then you would probably have to use photogrammetry to get a decent representation of the material. Which in fairness can be done with a regular smartphone if I’m not mistaken, but it takes a lot of time and requires a good setup to be able to get something useful out of it. Preferably you’d want a better camera to get really sharp images to work with, and you would benefit from being a good photographer beforehand because it’s important that you get the right light conditions etc.
I think you can make 3D-models out of this process as well, but I don’t know how that works and I can imagine that it could be quite tedious work.
I don’t want to discourage you, but I think you would have to read up on the related processes quite extensively to have the chance of producing a decent end result. And you might end up needing some expensive gear as well.
If someone has more experience in this area, feel free to correct me on any wrong statements I’ve made.

Thanks for your reply, your reply made me much more clear about this process, and I’m looking forward if there is any other more convenient way to finish this workflow, thanks!
Depending on the precision you need, you have wide options from smartphone-made photogrammetry to 3D scanning with immediate color capture.
Funny, just see this topic but my answer on the other topic could fit here.
Like Oleksii says, there are some nice photogrammetry applications. I’ve only uses some on PC like Agisoft Metashape but there are plenty. If you take the piece inside and put it on a small object so it’s lifted from the ground you just shoot a lot of pictures, drop them into the software and you get your 3D model. Most of the time it needs some cleaning out of weird noise etc but a lot of tools can help you with that as well.
I think it does help a lot if you use some diffuse light (or a totally cloudy Dutch sky) so you don’t get really hard shadows. Most software will also take that into account since you don’t want them to be ‘baked’ in the diffuse map.
