Intelligent Herbicide Application System for Reduced Herbicide Vegetation Control Phase II – Commercialization
This report describes the development of a commercial prototype intelligent herbicide application system (IHAS). The improved design incorporates an add-on fluid handling system to allow existing variable-rate herbicide injection systems currently used on California Department of Transportation (Caltrans) herbicide spray vehicles to be retrofitted with IHAS technology, and a dual camera system for weed recognition under partially shaded lighting conditions. It 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 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 Caltrans to selectively apply post-emergence herbicides exclusively to the unwanted plant material. Implementation will allow Caltrans to reduce the amount of resources required to maintain an effective weed control program while at the same time reducing the amount of chemicals unnecessarily released into the environment.
