• Abstract:
  This report describes the development of a commercial prototype intelligent herbicide application system ; (IHAS). The improved design incorporates a parallel “add-on” type fluid handling system to allow existing ; variable-rate herbicide injection systems currently used on Caltrans herbicide spray vehicles to be retrofitted ; with IHAS technology, and a dual camera system for weed recognition under partially shaded lighting ; conditions. The new IHAS is capable of targeting green plant material within a 3.66 m perpendicular distance ; to the direction of travel on either side of the herbicide spray vehicle for herbicide application. ; The basic principal of an intelligent herbicide application system (IHAS) is that a real-time machine vision ; system can detect live (green) plant material growing along the roadside, and when coupled to a rapid-response ; spray control system, will permit the California Department of Transportation to selectively apply ; post-emergence herbicides exclusively to the unwanted plant material. The implementation of the IHAS ; technology will allow the California Department of Transportation to reduce the amount of resources required to ; maintain an effective weed control program using herbicides while at the same time reducing the amount of ; chemicals unnecessarily released into the environment.
