Re: 3D scanning - high resolution for small objects

I know that in Russia it is almost impossible to buy PF1500 (or its next generation - HF60). If such an advertisement comes across, then the projector instantly "leaves". We have an average price for such a used one in good condition around USD550-750 P.S. I am not aware of the exact differences in ...

Re: 3D scanning - high resolution for small objects

Among the newer projector models, there are almost no options with suitable specifications. All manufacturers try to make the picture bigger by reducing the projection ratio.
One of the best for use in a scanner is the LG PF1500, but the model is old and difficult to find even used on sale.

Re: Daheng Mercury MER-630-60U3M-L - 2 camera can work with HP3Dscan

I calibrated in this order: 1. First, in Rangevision (because there are rather strict restrictions on the size of the table in the frame), 2. With the same relative position of the cameras and the projector, did the calibration in HP3DScan (which is not so critical to the visible size of the table i...

Re: RC Car Component Scan

I would like to ask you to try these program settings with your cameras. I get the best quality scans with them (and the fastest, besides). photo_2020-08-05_20-10-31_cr.jpg I used them with old Mindvision SUA630-M cameras and current Daheng MER-630 cameras (all these cameras also have a monochrome I...

Re: RC Car Component Scan

There are a lot of reasons and options for scanning quality ... related to both software settings and hardware. I use a low resolution projector (1280x720) so I have to put it closer to the object to get the maximum pixel density of the projection on the surface. And then the selection of the positi...

Re: RC Car Component Scan

I've tried to upload a video of the issue i'm getting. My current cameras also do not remember all settings in David / HP. The shutter speed (I put 16667.000) is remembered, but all the time I activate sharpening in the settings (and with it the speed drops from 60 to 20fps and the quality of the s...

Daheng Mercury MER-630-60U3M-L - 2 camera can work with HP3Dscan

Maybe this information will be useful for someone. Today they shared with me a link to very old drivers for my Daheng Mercury MER-630-60U3M-L cameras (which worked fine only in Rangevision ScanCenter (we are talking about two-camera mode), and HP can only work with one camera). Now, with these ancie...

Have you turned on permission for HP so that it can independently store settings? Advanced Settings-->Camera-->EnableAutoPropertyHandling?

Re: RC Car Component Scan

Good scan. But on each of its parts, before joining into a single model, I saw distinct bands from the desynchronization of the frequencies of the camera and the projector. You need to choose this parameter better (if the camera has the ability to accurately extrude the shutter speed). Or double the...

Re: 3D scanning - high resolution for small objects

I guess we will all have to upgrade to 4K projectors. :) I do not know yet "real" 4k projectors (mostly there is pixel shift technology). While this is about the same as in cheap models from the DMD 0.23/0.33" 1366 * 768 matrix they make FullHD, but here they get 4k from the FullHD DMD 0.47" matrix...
