I am new to photogrammetry, and would like some tips and also to know if I am doing everything right in terms of process and how to optimize the scenes, in order to achieve the process with the best quality possible but also in the shortest time.
Currently, I have a Canon 1300D camera and 2 lenses, a Canon 20mm 2.8 and a Canon 50mm 1.4, and I also have a Godox 400AR Flash Ring. Currently, whenever I go to photogrammetry some object or scenario, I try to make as many photos as I can with each lens (usually between 300 and 1000 photos, depending on the size and complexity of the object or scenery). And so, I basically repeating the same process with each lens. I start to shoot from afar, always taking a general scenario, when I complete a whole lap, I repeat this lap shooting from the bottom up (sitting on the floor ) and then from the top down (climbing a bench or ladder), after that I repeat this process closer and closer to the subject, until the part of photographing the details.
Generally I choose the 20mm lens and make a second round with it, this time using the Godox 400AR flash ring, following the same protocol and trying to adjust the power of the flash manually, every time I approach the subject. In the end, I have a lot of images made with the 20mm, a lot made with the 50mm, and a lot with 20mm+ringflash.
I align each batch separately, and export each batch as a component and then import into one final scene.
I always use RAW images directly from the camera, I do not go through any program nor convert to any other format (is that right?).
Once in the final scene, I always try to generate my mesh in high detail, then colorize, texturize and then simplify the mesh and export it (I do not always simplify the mesh in RC, I usually try to simplify it in Zbrush, but most of the time the mesh is so heavy that it does not even open on Zbrush).
One thing that has been calling my attention is that the texturing part of the model is taking forever ... in general 4-5 times more than to generate the work in high detail. When I start texturizing the model, the program starts to demand a lot from my machine and the processor stays at 100% most of the time, and then a drop occurs and is between 10% and 30%, with a constant use of memory in 50% and practically no GPU (which is a shame, because I have 3x1080Ti).
Probably my process is not optimized and I would like tips from you to optimize, but with never lose quality. Any tips and tricks are welcome and link as well.
thanks a lot, guys and sorry for the poor English!
