This idea is used to serve my old idea of "Image stabilization by means of software.". I was aware that it was difficult to find angular sensor that can run at 1MS/s. I will have a cubic enclosure, two perpendicular walls are made of small/fast image sensors. I use a hanging ball and a laser to shine upon it. The image sensors will detect the exact location of the ball (hopefully 1000 times a second). When the enclosure(thus camera body) shakes, the ball will remain inert for that short period, Thus the image sensors can give a reading of the balls location and calculate the displacement. Does this idea work? :)

Maybe if you were making the application work on an fpga with an embedded processor, using a DSP algorithm based on images of a small ball, but... Jeremy

In a crosspost apparently to cover all the bases, specifically to alt.sci.physics,comp.arch.embedded,comp.arch.fpga,comp.dsp,sci.image.processing, On Fri, 17 Jun 2005 10:07:50 +0800, "Kris Neot" <Kris.Neot@hotmail.com> wrote:>This idea is used to serve my old idea of "Image stabilization by means of >software.".What does that mean? You want to generate a signal that represents a change in the position (orthogonal or angular? both?), and use this to translate a digital real-time video image from a digital camera sensor to make it appear stable?>I was aware that it was difficult to find angular sensor that can run at >1MS/s.

Is that what you want? Also, I can think of several other ways of doing this. I'd probably use these things: http://www.analog.com/en/cat/0,2878,764,00.html> >Does this idea work? :)Yes, probably, sort of. ----- http://www.mindspring.com/~benbradley
