Statistics and Line Profile
This function allows the User to get some statistics on a pre-defined ROI. On request, the Camera acquires and then
calculates some key values as the min, the max, the average or the standard deviation in this Region of Interest.
The grab and calculation command and also the collection of the results is not performed in real time as it is done
through the serial connection.
This function and the results are available in CommCam in the “Line Profile Average” Section :
Line Profile average measurement (
LineAverageProfile
) :
Control the grab and computation of the statistics.
Read function : “r pixs” : Get the status of the calculation
Returned by the camera : 0 : finished, 1: running
Write function :
“w pixs 1” : Start the accumulation and then the computing
“w pixs 0” : Abort the computing.
The Calculated values are detailed as following :
For the Red Pixels
o
Pixel average Value (
RedPixelROIMean
) :
Average Red level value calculated on whole Region of interest
Read function : “r pavr” : Get the average value
Returned by the camera : Unsigned format value : U12.4
o
Pixel Standard deviation (
RedPixelROIStandardDeviation
) :
standard deviation of all the Red pixel level values of
Region of interest
Read function : “r pstr” : Get the standard deviation
Returned by the camera : Unsigned format value : U12.4
o
Pixel Min value (
RedPixelROIMin
) :
Minimum Red level pixel value on the whole region of interest.
Read function : “r pmir” : Get the Minimum value
Returned by the camera : Unsigned format value : U12.4
o
Pixel Max Value (
RedPixelROIMax
) :
Maximum Red level pixel value on the whole region of interest
Read function : “r pmar” : Get the maximum value
Returned by the camera : Unsigned format value : U12.4
For the Blue Pixels
o
Pixel average Value (
BluePixelROIMean
) :
Average Blue level value calculated on whole Region of interest
Read function : “r pavb” : Get the average value
Returned by the camera : Unsigned format value : U12.4
o
Pixel Standard deviation (
BluePixelROIStandardDeviation
) :
standard deviation of all the Blue pixel level values
of Region of interest
Read function : “r pstb” : Get the standard deviation
Returned by the camera : Unsigned format value : U12.4
o
Pixel Min value (
BluePixelROIMin
) :
Minimum Blue level pixel value on the whole region of interest.
Read function : “r pmib” : Get the Minimum value
Returned by the camera : Unsigned format value : U12.4
o
Pixel Max Value (
BluePixelROIMax
) :
Maximum Blue level pixel value on the whole region of interest
Read function : “r pmab” : Get the maximum value
Returned by the camera : Unsigned format value : U12.4
