Realtime HDR Video
Posted 10 September 2009 - 02:24 AM
So, here's my dilemma...
We are looking for two possible pieces of the puzzle. Either, a small mirror/prism rig where 3 A1's can connect to it and film 3 versions of the same EXACT image, OR, find a program that has the ability to take 3 slightly offset images/videos and warp them to one of the videos so they all look identical. I imagine the computer taking the features of one image, and then compares it to another image that's slightly different (taken from another camera 2 inches to the side of the other), and warp the image to the details and features of another. I've looked into stereoscopic workflows and such, but it only gets me so far, since stereoscopic video is trying to produce two slightly offset images instead of 2 identical images. Again, I'm dealing with 3 images that I'm trying to make identical, even though the cameras will be inches apart.
Any ideas? We have a workflow figured out and everything, but we are just missing that last piece of the puzzle. Once I figure out this roadblock, I've done it. Real-time HDR Video. Finally.
This is what I've produced so far.
Those 2 cars you see that look ghosted are actually the same car. Each exposure that was combined was a different moment in time, since this test was done with a single camera. I have yet to produce a great quality image from 3 cameras, obviously, that's what this post is for.

I would imagine an HDR camera would have to be more like a 3ccd camera but with 3 cmos chips after the beamsplitter. That would make a usefull HDR camera with only one lens.

Still, I don't mean to say the OP shouldn't try to build that 3 camera rig, however unwieldy and cumbersome it may turn out to be. Certainly, the exact alignment of such a rig would an absolute must.
Also, the cameras may have to be so close together that some controls may be inaccessible after mounting them on the rig. This set up may be best suited for cameras that can be controlled remotely / or with paintboxes. I forget if Canon has a software to control cameras through PCs.
