Help needed by algining photos
« on: January 30, 2014, 03:30:41 PM »
Hello there,

I'm currently testing the photoscan programm (30-Day) trial.

I'm experiencing some kind of a problem with a test object.
Made some photos of a flower but the point clould model is really spare.

Why do I have this problem ?
Is it because of the image quality ?

Thank you very much for your help !

Best regards

Hello DAS.Zentrum,

The object you are trying to capture is not the best choice for the first experience due to very thin object structure. Also using only two photos will produce dense cloud (and mesh) only for the area of overlap.

So the result seems to be even better as I could expect for such object.

Thanks for your Info,

so is it generally possible to get such detailed 3D models ?

How is it by having photos of surfaces that are shiny (e.g. vehicles or buildings with lot of windows) ?

Objects with shiny surfaces can't generally be used.  You must find a way to alter the lighting or the surface of the object to eliminate such surface properties.

Ok, thanks for info, so maybe it is possible to use photos with shiny surfaces, that are reworked in photoshop or something like that ?

By the way ... took a lot of more pictures of my flower and got a lot better result out of it !
