摘要
Abstract
In order to collect the power consumption information from smart meter in the field,handheld terminal has been developed rapidly.However,the precision and processing speed of laser facula counterpoint in existing handheld equipment cannot meet the demands.Pointed to a kind of handheld terminal used by SGCC,a new detection method of laser facula which can realize the rapid counterpoint and helps to solve measuring field problems is put forward.This method consists of three parts,including image identification,laser faculacenter location and its size calculation.Through comparing the global threshold algorithm and the local threshold algorithm,the Otsu algorithm is the optimum choice of former procedure for image binarization processing.For the other steps,a new computing method of laser facula center location is proposed after considering the speed and accuracy of the counterpoint.The method has been proved to be effective in improving the accuracy and efficiency of the measuring handheld terminal by the instance.关键词
