Camera Match Not Working


Recommended Posts

Matt,

   I can't thank you enough for you personal assistance with this.  You really helped me understand the importance of accuracy with the perspective lines.  I also did not realize the importance of making sure that the reference object was in line with the perspective lines.

  For the forum - if anyone is listening - The problem was that I had the reference object way far away from the perspective lines, and not really on a point that the perspective lines were converging on.  I also had my vertical perspective lines what I thought was just a couple pixels off.  A couple pixels is a big deal.  It really needs to be super accurate and you need to be sure that the vertical element in the photo that you're using is actually vertical.  If you're using something like a pillar you're probably fine, but if you're using something like a home-made accent piece somebody installed, you're trusting your accuracy to that guy's spirit level.  Thanks again Matt for your above-and-beyond level of support.

You're very welcome! I'm happy to help!

 

Just to clarify, the reference object (in the design layer) and the reference target (in the Camera Match object) should be placed somewhere on the vertical place containing the measured line (the control line given a dimension). This is assuming you're using a left or right control line as the measured line. If using the a vertical (blue) control line as a measured line, the reference should be placed somewhere along the axis of that control line. The purpose of this is to allow Camera Match to calculate the proper camera distance. If the reference is not placed correctly, it results in the wrong camera distance. Just to note: The camera distance can still be corrected using the tune view's "camera distance" control. So don't get TOO worried about this.

 

As you mentioned, the accuracy of the control lines is very important. All three vanishing points directly effect one another in the calculations (in ways you may not expect).

Let me know if you have any questions.

@Matt Panzer  this is a really helpful video! I can't believe it's not more widely available. I've been trawling through every bit of info on Camera Match I can find + unless I missed it I don't believe anything out there explains the relationship between the Reference Target + the measured line as well as you do here. And showing so clearly how dramatic an effect tiny tweaks to the control lines have on the preview object. Might be four years after the event but really glad to have come across it so thank you

Hi Matt

 

Just trawling through your mini tutorial, very interesting, thankyou. My issue is that the Reference object and the Camera Match object don't line up. What's the point of putting those two points in if they don't align immediately and become the centre of rotation or scaling for the model? Also, can you use the horizontal reference lines instead of the vertical, I can't get a good vertical reference measurements for those lines.Cheers

These points should align when you click on the "Set View to Match" button in the Objet Info palette.  They also should stay aligned when using the "Fine Tune View" dialog (also invoked from the Object Info palette).  Is this not what you're seeing?

Yes. You can select any of the control lines as the "Measured Line" by selecting it in the popup in the Object Info palette.

Hi @Matt Panzer

 

Just watching this video as I have an issue with my Camera Match. Attached is a screenshot showing the model too high.

 

Following your video, I think I need to relocate the Reference Point but I can not get access to it to edit it.

 

On the Model I have placed it at the top of the wall, as I have placed it at the top of the wall in the image, as the bottom of the wall can not be seen. I have indicted the location of the reference point with a Blue Blob.

 

So, two questions;

 

  1. Why are the reference points not aligning with each other, and,
  2. I can can not seem to gain access within the viewpoint the relocate the reference points and lines. They are all hidden by the model. Shown this is the second screenshot.

 

Any help would be appreciated, as essentially the model is in the correct place, just way too high.

 

Kind regards

 

Mike

Hi

 

I seem to be having a problem with Camera Match. Despite the Reference Point being in the same place on the Model and Photo, (top of wall on the corner), for some reason Vectorworks thinks I want to build a house on top of a house, rather than at the same level.

 

I can not figure out why this is happening.

Hi @Michael Siggers,

Can you send me the file via direct message?

I've also notice that the Camera Match reference in mine does not show Green, Red and Blue. Could this be the issue?

 

Below is form the Online Vectorworks help

 

"The Camera Match reference provides Camera Match with the model’s orientation in 3D space. It is positioned on the model to define the planes where the vanishing lines lie. The three color-coded axes define the following vanishing points:

Green: Left vanishing point

Red: Right vanishing point

Blue: Vertical vanishing point"

Hmm... That does sound odd unless you have "Black and White Only" selected in your view settings.

 

I have not yet been able to download the file but I'll take a look at it when I can get it.

Hi @Michael Siggers,

 

Something seems off about that file that somehow triggers the shift in Camera Match's calculated view.  While I have not yet found why it's happening, I have found one (less than ideal) way that seems to correct it.  When I take your file in VW 2025, export it to a VW 2024 file and open the exported file back into VW 2025, the problem seems to go away!  Hopefully the will help you get around the issue for now.  In the meantime, I'd like to investigate this further when I have more time.

Thank you @Matt Panzer

 

This may get me over the hurdle at the moment. As I don't have VW24 on this machine, I'm assuming I can still export to VW24, then just reopen the file in VW25?

Right.  Just opening the exported file back in VW 2025.

I hope this helps for now.

Mmmm, has not worked for me. Must be missing something.

 

  1. Exported as VW24,
  2. Closed file,
  3. Opened VW24 file, got the usual warning and it added vw2025 on the end.

Still floating in the air.

Whew!  I'm glad it corrected it for you.

I submitted a bug with that file so we can take a closer look.  In the meantime, if you notice anything that seems to trigger the issue, please let me know.
