Re: problem with HP5.5 and HP5.6

This is just one version of why this might happen:
Do you have Advanced Settings -> Cameras -> PreventProcessorIdleState enabled?

Re: Bandpass filter for blue light scanning

As far as I know, my projector uses three LEDs (R, G, B). And in the HP3Dscan program I use, there is a scanning mode in white light, as well as red, blue and green. Unfortunately, there is no exact data regarding the emitted wavelength of the blue LED used in the projector, unfortunately.

Re: Bandpass filter for blue light scanning

I will try to order them soon. In Russia, Azure BP470 is not a cheap filter (the cost of one filter is $ 80). I found similar ones on AliExpress, but there is a small diameter, and the price is not much lower. So I’m almost sure that these filters are quite “correct”. But there are some doubts about...

Bandpass filter for blue light scanning

Has anyone bought and used a bandpass filter 470nm to scan shiny and mirror objects?
Something like that - Azure BP470:

Re: Some tweak for close-up calibration with dual cameras

It is possible (I cannot verify this) that such a calibration option will be incompatible, for example, with an automatic rotary table. With this position of the calibration table, the program thinks that the cameras are above and below the projector. Therefore, the scanned object is also turned to ...

Some tweak for close-up calibration with dual cameras

At some point, I was faced with the inability to calibrate in a dual-camera configuration if the distance to the panels is very small (and only one side of the calibration angle normally enters the field of view of any camera) I decided this by turning the calibration angle to the side. Then he got ...

Re: Some of my scans

Trying to scan something big enough. I made 12 scans from one point (only rotated scanner horizontally and vertically on a tripod). I used my largest 110mm calibration chart.

Re: Some of my scans

Do you coat any of the objects you are scanning? No, the scan was done "as is". I don’t have anything suitable for matting yet (and using ordinary chalk or other powdered products will require thorough cleaning after scanning - which I don’t want to do :-)) Here, for example, the coin loo...

Re: Projector recommendations

I use an portable LED-DLP projector Byintek UFO R9 (without Android) purchased on Aliexpress (1280 * 800). 20190515081554s.jpg The minimum focusing distance is 110mm, while the projection size is about 50x80mm, at a distance of 350mm (shown in the photo) the projection size is 250x150mm 201907031733...
