Slalom End Course Monitor

Video Jump Discussion Board: Video Jump Discussions: Slalom End Course Monitor

I started a new topic as the Overlay Program is now ready. It can be used for both slalom and jump. For slalom, you can put the end course video in the computer and monitor it dynamically, if your capture card supports overlay.
The program draws limit bars that move down the course with the boat always showing where the 20cm limit is. If the boat ever touches the bar, the path has exceeded the allowed limit. It is critical that the start is timed correctly to precisely match when the boat goes through the entry gates or the bars will not be drawn at the correct spots.

The program also monitors jump. This is a slightly different animal as there is no defined limit and the skier can choose his own boat path. The program has the option for three different boat positions and allows input of a limit value.

On both of these operations, it is also very important that the boat width be entered. The boat width is the widest point of the boat which is usually the outside of the rub-rails near the middle of the boat. It should be 2.2-2.4 m.

I'd appreciate feedback from anyone using this program. It is available at the utoronto site (the web address is under a different topic - it is the vs folder)

Have been playing with this program but am having provlems with the overlay. I have the vidcap32 program running in overlay mode, but when I swap to the boat path program I get the overlayed video for a second or two and then is disappears. If I switch between the program, the overlay returns for a second or two and then disappears. I am guessing that something in the boat path program is refreshing the screen an causing it to loose the overlay. Have you any idea why and how I can correct it?

I have a PIII 500 with 128Mb and a 32Mb NVIDIA Riva graphics card running at 1024*768 at 16bit colour with an ATI TV Wonder card.
