Video Detection

Video detection module for interaction with a camera.

Works as a motion detector, light zones or dark zones detection.

Example of 2 zones detected in motion mode:

Example where a sample is reversed when a zone is detected and where the horizontal position of the zone change the start position of the sample:

Settings

video in

Video input flow(s).

video out

Video output flow(s).

process time

Total time used for the calculation of the module.

luminance

Gives the average luminance of the current frame.

max value

  • In motion detection mode gives the maximum of the difference between the current frame and the previous frame.
  • In light zones mode gives the maximum luminance of the current frame.
  • In dark zones mode gives (256 - minimum luminance) of the current frame. Can be helpful for calibration and to adjust the threshold value.

detect mode

Detection mode.

  • motion: detects the movements.
  • light zones: detects light or white zones.
  • dark zones: detects darks or black zones.

threshold

Detection threshold and sensibility.

  • 0 always detected.
  • 255 never detected.

group tolerance

Determines if zones which are close together are grouped into a single zone.

  • 0 not grouped
  • 10 if the distance between two zones is less than 10 pixels they are grouped together.
  • etc.

nb zones found

Number of detected zones.

detected

Array of 0 or 1 with a nb zone found length.

For example if 3 zones are detected this output is the array [1,1,1].

zones X

X position of all the zones. Array of single (0..1) which gives the position of each zone on the X axis.

For example [0.23,0.67,0.96] is for a 3 zones detection, the first X position is at 0.23 the second at 0.67 and so on.

zones Y

Y position of all the zones. Array of single (0..1) which gives the position of each zone on the Y axis.

For example [0.23,0.67,0.96] is for a 3 zones detection, the first Y position is at 0.23 the second at 0.67 and so on.
