一、Basler软件安装

机器视觉软件及工业相机软件下载 - pylon, ToF 等 | Basler (baslerweb.com)
讯享网https://www.baslerweb.com/cn/sales-support/downloads/software-downloads/1）根据操作系统选择对应的pylon软件下载

2）打开安装包，选择Developer，Next

3）选择相机连接方式 ，本次开发过程使用网线连接，所以选用GigE

4）安装完成后，在你的安装路径下找到.\Basler\pylon 6\Development\Assemblies\Basler.Pylon，其中有32位和64位的动态链接库，在创建项目后引用Basler.dll

PS:在安装中遇到了一个错误代码，下载Pylon5,Pylon6都是同样的错误代码，最终解决办法是重装系统。QAQ

如欲安装失败，参考该文章

为什么出现 Baslerpylon安装错误如何解决？（8页）-原创力文档 (book118.com)https://max.book118.com/html/2020/0703/8044045033002122.shtm二、winform界面设计

需求

1）显示相机基本信息

2）调节曝光和增益

3）设置软触发和硬触发

4）单张采集和连续采集

5）显示采集图像的数量

6）保存采集到的图像

根据需求分别使用了以下控件

三、程序代码
