Hi,
Had a question re: a definitions or relationships on Object Size, Pixels & Graph overlay as used in BI. ver 4.5.1.4 (x64).
Found respective under >Trigger tab >Motion Sensor:
>Object size 100~1100
>Advanced >Object Detection >Object travels (pixels)
>Advanced >Use zones/hot spot >Graph overlay
I have an understanding of the variables such as a camera's focal length, field of view, depth of field, subject size(s) & distances, lens, mounting angle/position, resolution, etc. I'm trying to understand the correlation of these variables to BI's use of Object Size, Pixels & Graph overlay.
- ie.,
1) Object size, simply an arbitrary number based on percentage of image?
2) Pixels traveled -a percentage of cam image or actual pixels and can it be related to the graph overlay or Object size?
3) Graph overlay -Zone definition, are the blocks considered pixels or again just arbitrary percentages of the image?
Much appreciate any additional info, not already found in this forum.
...thx
