opencv3.4.0版本opencv-world340
OpenCV（开源计算机视觉库）是计算机视觉和机器学习领域广泛应用的一个开源库，它提供了丰富的API，支持多种编程语言，包括C++、Python、Java等。这个压缩包“opencv3.4.0版本opencv-world340”包含了OpenCV 3.4.0的特定构建和源代码，适用于Windows平台，特别是与Visual Studio相关的编译环境。
**OpenCV 3.4.0版本：**
OpenCV 3.4.0是OpenCV库的一个稳定版本，发布于2017年12月。在这个版本中，开发者可以找到许多优化和新特性，包括对深度学习的支持增强，新算法的添加，以及对已有功能的性能提升。OpenCV 3.4系列是一个长期支持（LTS）版本，意味着它会持续接收安全更新，但新功能可能会在后续的主要版本中引入。
**build目录：**
"opencv\build"目录包含了OpenCV库的预编译二进制文件，这些文件是针对不同的平台和编译器配置的。在本例中，“x64\vc15”和“x64\vc14”分别对应于Visual Studio 2017（VC15）和Visual Studio 2015（VC14）的64位编译器。这些编译好的库文件（.lib）和可执行文件（.dll）可以直接在相应的Visual Studio项目中使用，无需用户自行编译源代码。
**opencv_world340：**
"opencv_world340"是一个静态或动态链接库，它集成了OpenCV库中的多个模块，方便开发者一次性引入所有功能，而不需要逐一链接各个模块的库。这对于快速原型开发或简化依赖管理非常有用，但也可能导致生成的可执行文件较大。
**opencv_ffmpeg340.dll：**
"opencv_ffmpeg340.dll"是OpenCV用于处理视频流的组件，它基于FFmpeg库。这个动态链接库文件允许OpenCV进行视频读取、写入和编码操作。由于FFmpeg的许可证问题，OpenCV通常不直接包含FFmpeg源代码，而是通过这样的外部库文件进行交互。
**总结：**
这个压缩包提供了一个完整的OpenCV 3.4.0构建，特别适合Windows平台上的开发工作，尤其是使用Visual Studio 2015或2017的用户。通过"opencv_world340"，开发者可以便捷地利用OpenCV的所有功能，而"opencv_ffmpeg340.dll"则确保了视频处理能力。对于初学者和经验丰富的开发者来说，这都是一个有价值的资源，能够快速启动图像和视频处理项目。
