Re: One Click VR - Ricoh Theta

Post by Geo Scan Surveying »

Thanks dhirota,

Im sure it is not the best camera out there but it would be nice to make use of what I have and willing to suffer a loss of image quality over speed of acquisition for colouring point clouds.

Does anyone know the riser height I would need to match the focal point of the FARO, specifically Focus M70? Alternatively, any suggestions on how I might accurately figure this out?

Best,
Sam

Great bit of kit for enhancing Faro Websharecloud.

We take images with this inside buildings and create virtual tours. adding annotations in WSC to hyperlink out to the photo tour stored externally.

I appreciate that the images are not native to WSC but a least it provides a cost effective solution to colour inside building, without the long capture times.

At the moment the images are stored on an external server which we hyperlink to via WSC.

I have put a wish list item to Faro for a dedicated storage area inside WSC Domain to host information such as this without the need for Box, Dropbox Amazon S3 etc

Hi,
we use Theta V with Faro Focus and the lens height offset is +25.5mm to the scanner mirror axes. The height of the camera from its base to the middle of the lens is ~110mm. I had a custom adapter made to compensate for the difference. Although resolution does not match internal camera of the scanner it is good enough to colorize 1/8 scans. Due to its HDR capability it captures much wider dynamic resolution in almost an instant. As Simon mentioned it's a great tool for interior scans!

Where did you have your custom adapter made? I managed to devise a contraption that gets the nodal point within 1-2mm but found out that Realworks can not colour scans converted from .fls. I wanted to avoid bringing scans into Scene but may have to explore how to colour them that way. As long as its workable it still beats an extra 4 mins on site per scan to take the photos.

It' a home made adapter, manufactured in my friend's garage. Just a simple metal tube with M/F threads on each side. Try to inquire in a local locksmith's they should be able to make it for you.

Interestingly I can colorize scans in Real Color with panos from Theta. I did about 100 scans the other day without a single mismatch. Do you mean exterior scans with sky in the zenith? I had problem with those, but I was trying to colorize it with stitched panos form a DSLR not a Theta.

Would you be willing to share this contraption idea? I have been tinkering for ages with this, but have not come up with anything quick and easy which doesn't involve a lot of fumbling around :(

You should be able to colour scans in Real Color, I can help you out with this if you need...

Hi Jared,

You are correct, it IS possible to colour .fls scans using Realcolour.
Really, I have found a solution by chance and sheer luck. The following two items combined raise the nodal point of the Theta to ALMOST match the centre of the Faro;

Here are the two adapters I have had made for approx. 100 Euro by a local company. One reduces the height difference between the Faro scanner and a manual panoramic head and the other to Gigapan. I haven't got the home made one for Theta with me at the moment, I'll try not to forget to post a picture once I get hold of it.
