How do you hope to "TRACK" anything without multiple frames and fast frame rate. The truck is moving 28cm per second. That's almost 2m in 7 seconds. What good would a single frame do? If it's fast enough to stop blur then you can not record any movement.If it's slow enought to go the distance it will be a blur.The resolution you need is not so much pixels in the frame.(You only need enough resolution to resolve the target on the truck) It's frames per second resolution you need or frames per meter traveled by the truck. Maybe one frame every 2cm.. so about 15 frames per second. A good video camera with shutter speed control will do the job if you set it to 30 frames per second and a high shutter speed, you can track close to 1cm of travel per frame. and get 200 frames in 7 seconds. You'd have to start the camera before thr truck passed and then turn it off after the truck passed.An ordinary still camera will not get you close to this although each frame will have great resolution the frames will not be close enough together to be useful. In any case you don't need such great resolution if your frame of reference is only 1 or 2m wide.700 pixels resolving a 1 m frame gives you about 1.5 cm per pixel. so a 15cm door handle will be covered by 10 pixelsemail me off list and I'll send you a diagramherschel_________________________________________________________________
