Using separe image sets for Mesh and Texture

Hi,

For our scans, it is always challenging if there are some glossy or translucent parts on the scanned mesh.
Putting a spray is one solution for the mesh but we lose texture information after spraying.
To solve this,

1] Is it possible to use 2 image sets ( 1 for the mesh, 1 for the texture) and combine in RC?
a. capture images with original object
b. put a matt spray and random marks to the object and capture images
c. Reconstruct Mesh using only images from b.
d. Color the mesh using images from a.

2] Is it possible to use Laser scanners for the Mesh and use images for the textures?

Regards,

Hi Justin

  1. Yes, it’s possible to DISABLE particular images for alignment, reconstruction, texturing. Just select the image(s) and set the settings…
  2. Yes, it’s possible to reconstruct only from laser scanner data or just images.

Hi,

Thanks for the feedback!
1] Is CR possible to import mesh data (obj) from Laser scanner to align info from images rather than E57, PTX files?
2] If it is not possible, please correct below process is correct.
a) import PTX or E57 from laser scanner
b) import images
c) align images and PTX or E57
d) construct mesh using only PTX or E57
e) color mesh using only images
f) finalized 3d model is ready (mesh+texture)

We are considering laser scanner to capture mesh of commercial product (shoe, cloth, speakers, bags …). We are not using mesh as reverse engineering or architecture so just clean mesh + photo-realistic textures is enough.
We were having issues with glossy material which was affecting mesh extortion and surface noise (this happens with non glossy material too).
3] Do you think using laser scanner might fix this?
4] Is there cost-effective laser scanner you might suggest? (e.g. Leika Blk360, Creaform HandyScan700)

Regards,

No, it’s not possible.

a) import PTX or E57 from laser scanner
b) import images
c) align images and PTX or E57
d) construct mesh using only PTX or E57
e) color mesh using only images
f) finalized 3d model is ready (mesh+texture)

Yes, this is the right workflow.

The scanners are not suited for “small” subjects like this. and most of the scanners can‘t export PTX or E57 in the right format…

I see. Thanks for your kind answer !
1.Could you name the scanners that were proven to work with CR for the small object?
2.Also, do you think laser scanners can fix noise and extortion issue?
3.Moreover, if the laser scanner is not the right solution how do you think about below process?

a) import image set taken from an original object
b) import image set taken from an original object + matt spray
c) align all images
d) Will it generate 2 chunks? Need manual alignment with control point?
e) Run high detail mesh reconstruction using only images set b)
f) color mesh using only images set a)
g) finalized 3d model is ready (mesh+texture)

Thanks,
