I use 6.3MP cameras operating at 60fps (they can also work as 2.3MP (FullHD) at 60 or 120fps) - I do not observe differences in scanning speed between 60 and 120fps, since the projector frequency is limited to only 60Hz (actually 60fps).

The main increase in speed can be achieved by lowering the resolution of the cameras and reducing the number of patterns that the projector displays on the scan target.

FPS has literally zero impact on scan speed.

Well, I wouldn’t say that ... after all, there is an addiction. I have many different cameras ... one that produces 8fps and has a resolution of 3.1Mp requires about 40 seconds per scan step .. 5.1MP camera with 16.7fps allows you to do one scan in 25sec.

Ok, to be more specific, above a certain threshold, which is the projector and the software speed of changing the patterns, higher FPS has no benefit, so there is no difference between between 30 or 300 fps.

 

Also higher FPS cameras that are also high enough resolution need a very bright light source and I don't think this will be conducive for SLS

When using a "typical" projector with a display frequency of 60 Hz, an increase in camera speed above 60fps no longer plays a role. However, if the projector (and such models exist) is capable of delivering 120Hz, then the camera will be able to work faster (but, again, the restriction comes from the projector again)

P.S. My main camera uses the sony imx178 matrix - this is one of the best (and fastest) matrices, both in terms of quantum efficiency and low level of intrinsic noise.

yes I test it,,,, I  change the frame and get more speed,,,,but I wonder what will happen if increase the speed to at lest 120fps how time it will take?.

It is extremely difficult to guess how long a scan with a high-speed projector can turn out (there are a lot of influence factors, including computer power, etc.).

Scanning in this program goes through two stages - optical (when data is collected from the camera) and "mathematical" (when this data is converted to a point cloud). If the first stage is more dependent on the number of patterns, but the second - on the resolution of the camera. In my case, if I take the full resolution of 6.3 megapixels to the second stage, it takes 5-6 seconds, then in the resolution of 1.3 megapixels it takes about 1 second. (at the same time, in both resolutions the “optical” part takes about 5 seconds at 60fps)
