Part Number: DLPLCR4500EVM
As a test I would like to displaysix images on the 4500EVM and capture them manually through my camera. See images below
I have looked at the training videos and I just want to clarify that I am doing this correct or if there may be an easier alternative.
Each image is 8 bit
As best I can tell I should

Thanks for the feedback so far.
This is an experiment we are trying to perform based upon fringe projection and extracting 3D point cloud from the images.
To keep it relatively simple we were going to trigger the camera capture manually so we were hoping to show each of the images for a period of time ( say 3s each frame) and snap a camera image during the 3s interval. We can automate the process at a later stage
The GUI version is 3.1. I found an updated training video that resembles more the GUI that is in 3.1 but I am still a little unclear of the following.
How do I show the fringe pattern once it’s uploaded as part of the 24 bit image? I couldn’t see from the video how you would show an image like I have attached. It showed more how to show red green and blue patterns.
Hope this helps clarify but let me know if you need more detail
In reply to John Traynor:
I forgot to add the link the training video I was looking at. Like I said I think the difficulty we are having is how to 'play' our image pattern once we upload it. We will have 12 in total we need to sequence through
Thanks in advance
Sorry for nagging you. Any luck in figuring out my question on how to display the fringe patterns on the 4500? I'm under pressure here in work to get this resolved.
I managed to upload and pull out the images from the firmware over the weekend. One last area I am struggling on.
Based upon the image above which is 912 x 1140 how do I modify this to take into account the unique diamond configuration of the 4500?
If I don't alter it and leave it as it currently stands what artifacts will I see for my given image after it is projected through the 4500?
Still a little confused on this one. In some of the posts you highlighted above it says I would need to alter the image and in another it says I can directly upload the 912 x 1140 pattern and it will just work.
Saying that I have uploaded the pattern as 912 x 1140 and it looks OK when I display it bar the the image seems to be banding.
See this image
Is this related to the post I have linked below? I get the same problems when I display the internal pattern ramp. Any ideas?
You can display a 912 x 1140 image and it will be displayed pixel perfect. The confusion comes related to the fact that it will be pixel perfect in regards to a diamond grid. Therefore, it will appear to be stretched in the x axis . The only reason you would need to modify the image is if you designed your patterns without taking into account the diamond pixel mapping. See an example below of how vertical lines in an orthogonal array would map to a diamond array.
