【车道线检测】基于计算机视觉实现视频车道线检测含Matlab源码

1 简介

  1)图像预处理：依次经过图像灰度变换、二值化、提取感兴趣的区域，最大可能的过滤掉干扰信息；

2)设置连通面积阈值，去除连通面积小的区域，进一步过滤干扰项；

    3)求出车道线的直线方程，得到车辆在车道中的位置。

2 部分代码

function varargout = Main(varargin)
% MAIN MATLAB code for Main.fig
% MAIN, by itself, creates a new MAIN or raises the existing
% singleton*.
%
% H = MAIN returns the handle to a new MAIN or the handle to
% the existing singleton*.
%
% MAIN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAIN.M with the given input arguments.
%
% MAIN('Property','Value',...) creates a new MAIN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Main_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Main_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
