Preclusive zone goes into la-la land
Posted: Sat Jun 10, 2006 6:16 pm
Everything working great here with 4 zones on 1 monitor. I decided to try a preclusive zone to eliminate false alarms from overall brightness changes in my image. I have a roadway in the upper corner of my monitor, and large objects going by cause the camera exposure to auto-adjust. My central zone can have a legitimate alarm pixel max of 90,000, which is the majority of the zone. But if I get this many alarmed pixels in my secondary zone as well, it generally indicates an exposure change.
Not fully understanding how to apply preclusive zones, I added a fifth zone that was rather large and overlapped my other 4, figuring that I could set the min alarmed to something like 120,000 pixels. This now strikes me as probably a bad idea from a computational standpoint. It may not be relevant, I don't know. But now I have:
Whoops, bail. Something has gone wrong, so I delete the zone. But the problem logs remain, zma is still ill. Restart all processes, even reboot the machine. Zones table in the db looks ok.
I think I broke this once before, and eventually rebuilt all the zones from scratch. It won't take me long, but just wondering if anyone had any brighter ideas. I'm still on 1.22.1.
