A real-time plant discrimination system utilising discrete reflectance spectroscopy
We present an advanced real-time green-from-green plant discrimination system. Uniform power multi-spot beams are used to illuminate the target vegetation. Spectral reflectance measurements are captured using a line scan sensor. Three laser diodes are used to compute dual NDVI discrimination parameters. Reliable plant detection and discrimination is attained for a 3km/h vehicle speed.
