⛄ 内容介绍
对交通灯的识别主要基于对交通灯的色彩及形状特征.基于信号灯的亮度对其进行分割,提取,并设置了一种自动最优选择阈值的方法.再由HIS彩色空间的H信息识别颜色.最后根据二值化的交通灯的横坐标和纵坐标方向的投影进行形状匹配识别.
⛄ 部分代码
function varargout = Traffic_Iden(varargin)
% TRAFFIC_IDEN MATLAB code for Traffic_Iden.fig
% TRAFFIC_IDEN, by itself, creates a new TRAFFIC_IDEN or raises the existing
% singleton*.
%
% H = TRAFFIC_IDEN returns the handle to a new TRAFFIC_IDEN or the handle to
% the existing singleton*.
%
% TRAFFIC_IDEN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TRAFFIC_IDEN.M with the given input arguments.
%
% TRAFFIC_IDEN('Property','Value',...) creates a new TRAFFIC_IDEN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Traffic_Iden_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Traffic_Iden_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
