I do have PDC in my car, but it's disabled for the moment. :)
It all turn down to your favorite color... some like black, others pink... a matter of taste.
I disagree. The few seconds that it takes you to turn your head may result in an accident also. If the screen is covering all sides of the car, why would you turn your head? Now when these ladies reverse, its just because their abcent minded. I think if a screen comes on infront of them they are likely to pay attention to it. You are using your own eyes, your just looking at a system that has even more eyes and can see better.Quote:

1) Camera: like guino said, there are inexpensive usb-video adapters in the market and a simple code could easily receive the image. Even for the AV output camera, a video capture card can convert it to digital USB output. A camera with infrared will be a advance option.
2) Video Merger: The point is NOT to look the 4 cameras, it is the bird view which comes from the 4 camera (look at the left side of the pic). So a video merger is required.

3) Specific Video function: Beside the video merger, speical video function is also required. Since the camera has wide-angle len, the image is curve view(I don't how to say). The program need a speical function to convert it to the normal view. Just like the pic show:

that's a pretty cool idea, just needs a lot permanent modifying your vehicle. i would like to see it implemented.
I think the physical mod is only the 4 camera. The front and back side are easy. So only need install the camera in the rearview mirrors. Anyway, the mod is not difficult, the hard one is the video processing (rectification and merge)Quote:

You can just connect the digital quad processor to the AV part of your screen. Then hit the button PC/AV button to switch between PC and Cameras. If you want the image on a PC, then simply add a tuner card to the setup and have the Digital Quad Processor connect to that. My experience though is that USB tuner cards tend to have hibernation issues, so you may have to get a pci version. In my setup though I wanted Superior audio and there for had no PCI slot available. I then decided to just have separate systems.Quote:

I am sure that other versions do the same thing, but since I have only played with this one, I have never tried.

I think you are missing the point with the 4in1 screen.
The point is not to have 4 camera's images on the same screen. The point is to have the 4 camera's images modified and twisted through real time processing to create a single bird's eye view.
The video processing will not be easy, but it is doable. You will need really beefy hardware to even think about accomplishing this. Might even be easier to just rip out the embedded system from a Nissan...
Yes, it is the point.
First, we can get the 4 video stream from the 4 cameras, it is the easy part. Next, need a program to process the 4 video stream and create a single bird's view, which is a difficult part. That is why I request a plugin.
Theoretically, a API function can do this. Input are 4 image and output is the integrated image. Need some guy with image knowledge to help on this.

I would expect something like this to cost between $100-$200 out of the middle east, or between $1k-$3k out of North America.
I dont think anyone will donate this much time to a project for free.
This is awesome... something I always wanted!
Is it possible to use some kind of optics to get it done simpler?
