1 简介
交通标志的检测与识别是智能车无人驾驶的重要组成部分,它也是解决交通安全问题的一种有效方法。在现实中由于分辨率,气象条件,照明强度和运动模糊等干扰,交通标志的图像质量通常很差,很难被检测,所以如何排除以上干扰,提高交通标志的检测和识别准确率是当前这一领域亟待解决的问题。交通标志的检测与识别问题主要包括两个部分:如何在获取的图像中准确找到交通标志,如何对提取的交通标志图片实现准确识别或分类。本文采用不变矩特征模板匹配算法实现交通标志识别。
2 部分代码
function varargout = trsUI(varargin)
% TRSUI M-file for trsUI.fig
% TRSUI, by itself, creates a new TRSUI or raises the existing
% singleton*.
%
% H = TRSUI returns the handle to a new TRSUI or the handle to
% the existing singleton*.
%
% TRSUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TRSUI.M with the given input arguments.
%
% TRSUI('Property','Value',...) creates a new TRSUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before trsUI_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to trsUI_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
