The intended application for the camera is to capture the movement of the
vehicle as it moves on the road. I would like to capture it's bouncing
motion due to the road surface.
1) My budget would be anywhere from $100 to $10000. Although I would like
to know what I
achieve if money was not an issue.
2) I would like to track about 2-7 seconds of movement.
3) How many images I take will depend on the accuracy I can obtain from the
pixel dimensions.
That is I don't want to capture repeated images (fast frame rates), while at
the same time I want to be able to track the movement of the smallest
feature without too much 'jump' from frame to frame.
4) 80-100 km/hr across the camera. I.e. the camera will be placed on the
side of the road.
5) I just need to track the smallest feature, so anywhere between 2-5 pixels
square would be adequate.
6) It is important to track the vertical bounce of the vehicle. Not sure
what I need the pixel of the scene to be for this.
7) This experiment will be conducted during the day, so the lighting
available would be just the normal sunlight.
I hoped that clarified what I need.

Finally!
Something I know something about!
Actually I need to analyze the images that I capture with a software
package (Labview) in real time, or as near as possible. I would prefer
that the equipment remains stationary. I need more technical details
about the type of equipment I need, i.e. how to work out how much detail I
can get (smallest feature I can detect), with what type of equipment. For
example say I want to detect the door handle on the vehicle from the side
of the road. Is that possible at all? and if so what equipment would make
it possible?
Understand that there is a staggering range of camera equipment that falls
under High Speed Imaging.
Shutter speeds to one micro-second ... and faster.
Frame rates to one million/second ... and faster.
Resolution to one million pixels ... and beyond.
Just about anything is *possible*.
So let's start with a few questions:
- what's the budget? (sorry, but are we talkin' $200,000 or $200 or ...)
- how long is the 'event' (or sequence of pictures you want to take)?
- how many images do you want/need during that period of time?
- how fast is the target moving, and at what angle (orthogonal, other) to
the sensor?
- what is the distance from the target to the sensor?
- how many pixels do you want of the smallest detail? (eg, 10H x 4V of the
door handle)
- how many pixels do you want of the scene?
- what light is available? (HSI Rule #1: if the target ain't smokin', add
more light)
THOUGHT FOR THE DAY: All that glitters has a high refractive index.
