使用Visual Studio 2015的OpenCV（msvcr120d.dll错误）

Question

我尝试将 OpenCV 与 VS Express 2015 关联起来，就像我在VS 2013中所做的那样，但我得到了.dll was not found in my system.。它说这是// emulating csv file String[] lines = { "shape id day hour week id footfall category area name", "22496 22/3/14 3 12 634 Work cluster CBD area 1", "22670 22/3/14 3 12 220 Shopping cluster Orchard Road 1", "23287 22/3/14 3 12 723 Airport Changi Airport 2", "16430 22/3/14 4 12 947 Work cluster CBD area 2", "4697 22/3/14 3 12 220 Residential area Ang Mo Kio 2", "4911 22/3/14 3 12 1001 Shopping cluster Orchard Rd 3", "11126 22/3/14 3 12 220 Residential area Ang Mo Kio 2" }; List<Integer> hours = new ArrayList<Integer>(); // | begin of input // || any number of characters, reluctantly quantified // || | 1+ whitespace // || | | single digit in group 1 (the hours) // || | | | 1+ whitespace Pattern p = Pattern.compile("^.+?\\s+(\\d)\\s+"); // here you probably want to only add the m.group(1) to your list, possibly as integer as it's done here for (String s: lines) { Matcher m = p.matcher(s); if (m.find()) { hours.add(Integer.parseInt(m.group(1))); } } System.out.println(hours);

关于如何将OpenCV与VS 2015 Express联系起来的任何想法？

Answer 1

我设法通过在我的系统上安装Visual Studio 2013 Express，使OpenCV Debug配置在Visual Studio 2015 Community Edition中运行。结果，文件msvcr120d.dll出现在Windows \ System32中，并且在重新启动计算机之后，我能够在Visual Studio 2015中调试OpenCV示例。

Answer 2

Prebuild Libs仅适用于VS11和VS12，这是Visual Studio 2012和2013.您可以为Visual Studio 2015 comm构建和发布自己的OpenCV库。版。 只需使用本教程 Install OpenCV Visual Studio 2015

Answer 3

在另一台计算机上安装Visual Studio 2013 Community Edition，然后将dll msvcp120d.dll和msvcr120d.dll复制到我的工作计算机的Windows \ System32 \中。为opencv 2.4 x64开发工作。

这不是opencv 3+所必需的，因为有可用的vs14二进制文件。
