OpenCV:为什么主分支中没有 OCL 模块？

Question

系统信息:WINdows 7 , 64 bit on INtel celeron dual core
我正在从 master 分支构建 OpenCV 库。按照 opencv 文档中的所有说明进行操作后，我得到了构建目录。但是我发现我的 OCL 目录不见了。我在这里:
C:\Users\Hesh\Documents\opencv_built\modules

为什么会这样？

这是 cmake generate 的输出:

你可以看到，上面写着 Use OpenCL = YES，那为什么模块 OCL 没有来？

编辑

我发现实际上在模块下的 master 分支中，缺少 OCL:

看这里:

https://github.com/Itseez/opencv/tree/master/modules

但它存在于 2.4.9.x 中

https://github.com/Itseez/opencv/tree/2.4.9.x-prep/modules

为什么会这样？

我想为 3.0.0 构建库，我认为这只能从 master 分支，但现在因为它缺少 OCL 模块，我该怎么办？我需要最新 3.0.0 中的 OCL

Answer 1

OpenCV 的主分支已切换到“透明 API”设计。该 API 将 CPU 和 OpenCL 实现放在一个统一的 API 下。因此不再需要单独的“ocl”模块。以下是描述更改的演示文稿:presentation .
