GROW MAP-leaf

Digital Image Sequence Processing Setup for monitoring of leaf growth via digital image sequence processing

Identification of leaf area, growth and chlorophyll fluorescence

GROW Map-LeafAjustment of lights and camera

Data Acquisition

  • fixation of a leaf in a plane parallel to camera
  • illumination with near infrared-diodes
  • image sequence at high frequency in near infrared throughout day and night

GROW Map-LeafSet up and evaluation of an experiment with GROW Map-Leaf

Image analysis

  • optical flow analysis of image sequence resulting in velocity vector fields
  • calculation of divergence to obtain growth maps

Results example
