|
|
We used the UFOCaptureV2 for meteor observation. I found that the 'Detect size'
in the 'Live sheet' changed itself. So I read the manual again and have some question about this software.
I don't understand the meaning the parameter of the 'Detect Level Noise tracking'('Input sheet' -->'Video Trigger settings')
(1) DLratio(105%-130%) = noise / Detect Lev or Detect Lev / noise ?
(2) What does 'MinL-N' used for? What is the meaning of keep margin?
(3) How does the UFOCapture define or calculate the noise level? |

There is no automated control of 'Detect size'. Did you mean 'Detect Lev' ?

It is Detect Lev / noise

It is important when noise level is small, such as 10, 110% of 10 is only 11 and it will be too sensitive.

It is the maximum of the pixel brightness level difference between two frames.
There are variety of observation systems. The answer can be different depending on it.
Could you describe your system (camera, lens, capture-equipment,video-format) first? |

Thank you for the reply. I understand the parameter much better.
Sorry for no descriptions of our observation equipment. It is described blew:
1. Camera: Watec 902H2 ultimate
2. Lens: Hikvision 0733D
3. 1394 video grabber
4. PAL-format
If the 'Detect size' would not be changed itself, I will keep paying attention to the software and find the reason. |

Detect Size can be changed only by below three cases.
1. Pushing of Detest Size up and down button
2. Clicking of the Detect Size slide bar
3. Reading of saved settings.
2. can be happen if you click the bar area of the window by some accident |
