Lego 007 car. Mostly grey, some chrome, some transparent ‘glass’, some black tires.
No spray, cross laser and shiny with the brightness turned down 15-20pts. Started w/ turntable and a springarm scanner mount, finished it by hand. Fused and isolation run.
Looks horrible, but it was looking good in the scan. Took foreeevvvver to process.
What could I do to enhance the scanning of these type things? I’m finding Lego kits to be quite difficult to scan. Done several Star Wars lego and none came out well except one TieFighter which is solid white and it actually scanned pretty well.
Then I decided I wanted to do the same thing in cross laser mode as I have not had much luck in this mode and wanted the practice.
Cross line, global markers, shiny metal.
I set exposure and brightness to auto after turning the brightness down 20%
Cross Line scan looks noisy, but otherwise good.
Sorry if subject matter offends, running out of interesting things to scan.
I can make full field work fairly well when tracking doesn’t freak out, but this cross line laser mode is really giving me a hard time. If I spray it I’m golden, but I’d really like to learn how to do shiny metals and black well w/o spray.
Try to catch at least 10.000 frames
Each object requires different approach so not really one solution for everything , laser scanning is time consuming , avoid to stay too much in one place , move it back and forth as much as possible from different angles.
The laser settings also will impact the results so testing out the proper brightness first in small part to ensure you have the best settings .
Try to clean it at different levels not just at 15% to ensure you get rid of all the isolated points from 1% to 100% you got lots of micro noises because of the scanning settings ( exposure and laser brightness) it can induce lots of micro noises around the objects of the values are too high or higher than the plate or other I jects beside the gun.
The settings are tricky , better to test out on small part first to avoid micro reflection noises .
I would have expected to hear from Revopoint team that they are working on this to improve. I’m scanning car scale models, mainly painted, a bit shiny and multiple colours.
I get the same results, even worse. Moreover, laser won’t pick red and black that is super annoying. What I would like to know is: will it ever be able to capture these type of surfaces and colours? Or this is the best it can do.
I know you will start to say about scanning techniques etc. I tried everything, dimming the lights, different exposures and laser brightness, scanning angles etc etc etc.
Just to adf fuel to the fire, I am an automotive engineer and I have access to other scanners so is not like I haven’t used something better.
I would like to hear an honest answer. PUTV, I know you are the interface so I would be curious what you know more from the technical team. Thanks.
Hi Adrian
The red color is the only remind issue when scanning with blue light or a laser.
For an obvious reason the red is absorbing the blue light so it can’t be fully reflect back to the sensors from the surface.
All other trouble colors was scanned without issues with laser mode or other modes using the dark mode scanning settings.
For the red I am using transparent 3D scan spray that helps to reflect the blue light better or a regular 3D spray.
I am afraid there is nothing else that can change the law of physics here.
You will need so strong laser power that would be too dangerous for the consumer usage and not really worth it.
Blue lights offers the best smooth results and accuracy in structured light technology. But as always there are cons.
Sorry that’s all I can offer you today with my reply.
