Chemical sucker control has been proven to be an effective substitute for manual and mechanical *** and location of suckers is the key technology of precision targeted spray which can reduce spray volume than current spray *** goal of this research was to develop a quick and effective segmentation algorithm of sucker images for real-time mobile targeted spray by evaluating and comparing seven segmentation algorithms categorized into segmentation based on color feature(ExG,ExGExR,and CIVE),K-means clustering segmentation in CIE L*a*b*space(K-Lab),and mean shift clustering segmentation based on color feature(ExG-MS,ExGExR-MS,and CIVE-MS)from time consuming and *** results indicated that ExGExR and CIVE took shorter time than other algorithms,and were more suitable for real-time *** further evaluating segmentation accuracy,ExGExR,CIVE,and mean shift algorithms were acceptable to kill *** ExGExR was the best algorithm for sucker segmentation in consideration of time consuming and accuracy,next came CIVE.

Chemical sucker control has been proven to be a more efficient method than manual and mechanical *** quick and effective identification and location of suckers are key technologies for targeted spray that can reduce chemical applications and alleviate potential *** goal of this research was to improve the accuracy of identification and location algorithm of grapevine suckers for real-time mobile targeted spray based on information fusion of two dimensional(2D)laser scanner and camera machine vision.A triangle white calibration board was used to determine the invisible laser scanning *** positions of the terminated points of the scanning line on the calibration board in the laser scanner’s coordinates were *** size and center location were obtained by ExGExR segmentation,then the relative position between the suckers and triangle calibration board was determined in the image ***,the actual size and relative position between the identified suckers and the platform were calculated by integrating the laser line and image *** results of the field trials showed that the consumed time of the developed algorithm was 0.787 s,the width recognition rate 91.8%,height recognition rate 88.2%,and the relative position accuracies 92.0%,87.3%,which could meet the requirement of grapevine sucker precision targeted spray.
