New to metro-X very slow frame rate - poor scanning

Discussions MetroX
1

Hi.
I just started tryin to use my Metro-X and the frame rate is only about 4FPS. M PC is pretty quick, with a 3TB SSD, an Intel I7 8 core 8th gen processor 32GB ram. I have a 1080Ti graphics card, and in general this has been a really fast PC. I have the Metro-X pugged into a USB3 port, and everything seems fine.

When I started scanning using the suppled smart turn table, I was getting only 4 FPS. Also, the object I was scanning (the Demo head) lost tracking often. Is this normal? It would be easy to blame the PC – but I really doubt that’s the issue. the CPU load was not very high. I was using both marker tracking and feature tracking using the blue-LASER scanning - very poor performance.

Any suggestions?

8th gen is below spec (10th). I would expect it to work ok though. In auto-turntable mode, FPS should only be 4-5.

FPS for me…
Auto-Turntable - 5fps
Full Field - 15fps
Laser (cross or parallel) - 45 fps

i9-14900hx
4060 GPU (8GB VRAM)
96 GB RAM

Auto turntable mode is low FPS because it’s only taking pictures when it stops turning. So it turns, stops, takes 3 pics, does it again.

Note that setup, marker placement, lighting, distance, color and a few other things factor into this working. One thing I find very annoying, the markers don’t track outside of the scan range. So you can’t just set them up, you have to consider that you need to keep the marker AND the object at the proper distance, or it won’t work. And you need at least 4 active markers being tracked (clean red circles in the main preview, NOT the small depth camera exposure view). You also need to keep them and the object within about 45 degrees from the cameras.

Most of the scanners have similar restrictions to get used to. So videos and such showing how to get started using one are all basically applicable. This should all improve with software updates soon, but there is no known timeline.

its normal to getting 3-4 fps with auto turntable mode

for mine expierence,
i’ve 3 machine
1950X with 1080ti or RadeonVII
macbook pro M1 Pro
and 13900H i9

all 3’s has similar result,
auto turntable mode : 4fps
laser mode, 43 to 46fps
12-14fps for full field scan

With the system you have you don’t get more frames , it is not good enough and below the recommendation.

This is the speed of my win tablet and it will not scan faster than 4 FPS , however ok with Full Field and Auto Mode

For laser scanning you need to have much more powerful system

Remember Auto mode is a still shot mode , it don’t need more frames so in Auto Mode it is the right behavior

Auto mode use still frames so the frame speed is not relevant .

I7 8th Gen is not enough to use Laser mode

I was way wrong on the CPU -
The PC has an I5 13500K – so 13th gen I5 so boost to 4.8Ghz, 14 cores, 20 threads. Is this enough CPU?

The Revopoint MetroX 3D scanner’s minimum CPU requirements are an Intel i7 10th Gen 10700 or AMD Ryzen 7 5800.

The recommended CPU requirements are an Intel i9 12th Gen or better.

The Full Field and Auto Mode can run fine even with i7 8th generation, but the Laser mode needs more CPU power.

You should have no issues scanning using i5 13500K using Full Field and Auto mode .

When scanning in cross-line mode, if you deactivate the scanning program window, the scanning frame rate will increase slightly. If you exit the window and click on the desktop right before starting the scan, the scan will probably be performed at about 10 to 20 frames.

Do your system have the minimum requirements?

Check if you have the latest Nvidia driver installed .

Laser modes runs at 57-60 FPS with the latest driver and RSM 5.6.4

But from what you saying it looks like you should update the driver or setup the graphic card to performance and see any improvement.

Hard to guess because I know nothing about your system , but the frame speed you experience is not normal .
I never got below 47 FPS even with early builds.
