# 环境
windows10 / visual studio 2015&2019
<br>代码基本没有使用系统api，你可以非常方便的移植到linux，可能需要做极少量的修改
<br><br><b>强烈建议你使用release模式运行代码，强烈不建议使用debug模式运行代码</b>

# 第三方库
opencv310
<br>
百度网盘连接：https://pan.baidu.com/s/1_WD-KdPyDBazEIim7NU3jA 
<br>
提取码：aab4
<br><br>
解压后放将名称为OpenCV的文件夹复制到到3rdparty文件夹下
<br><br>若运行时提示缺少opencv_world310(d).dll，则在OpenCV文件夹里找到对应的dll文件复制到程序exe所在的目录即可（Opencv\dll\opencv_world310(d).dll），带d为debug库，不带d为release库。
<br><br>
为便于移植，算法是不依赖任何图像库的，只在算法实验部分调用opencv库读取和显示图像，也可替换成其他图像库

## 备注
<b>算法优点</b>：效果好，内存占用低
<br><b>算法缺点</b>：效率低，速度比较慢，不建议跑大图，建议跑个小图看看效果（Release模式）。如果设置为前端平行窗口（PatchMatchStereo为倾斜窗口时效果最好），则速度会更快，如下：
>pms_option.is_fource_fpw = true;
