As it was previously noted, there are two exposures with different light conditions, to avoid light reflections on the shiny ball sufrace. The result is good image, with no specular points. After the frame fetching, data in frame buffer is rendered to mach 6-bit monochromatic pixel depth. There are two fixed variables, similar to contrast (gain) and brightness (offset), which are used to adjust every pixel, in the range 1...63 (zero is not used in the picture representation, as it will have some special role in later processing) All photos are took by the camera from VGA monitor. Here is the top row explanation: 01 Processing step number 00 Recording step (used only in number recording process) 00 Final result (ball number) or error report 0000 Final guess rate in %, ((best result) / (second best result) - 1) * 100 0111 Total processing time in miliseconds The numeric field at the right side is 16-bit memory hex dump. It can be scrolled up and down. |
