Siftgpu: Problems with compiling SIFTGPU-unresolved external symbols glutinit

OpenCV has an orb feature and a GPU version of surf,

Reference: OpenCV on GPU version surf feature points and Orb feature points extraction and matching examples as to what parallel APIs are used for the time being not explored.

But no opencv-sift GPU was found to be used. Need to compile, reference: Compile OpenCV GPU, use cuda acceleration

Siftgpu's original library can be compiled through. However, it is not available and leads to a series of 96 compilation errors when used.

Workaround:

Update Glew to version 2.0

2. After updating the Glew, the display still contains the unresolved glut function body for the original Globalutil.obj project:

1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol glutinit
1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol Glutinitdisplaymode
1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbols Glutinitwindowposition
1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbols Glutcreatewindow
1> Siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol Glutdestroywindow
1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol Glutgetwindow
1>siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol Glutsetwindow
1 >siftgpu.lib (globalutil.obj): Error LNK2001: unresolved external symbol Gluthidewindow
1>e:\codebase\codevalidsource\slam \orb_slam_wish\build\win\orbslam\x64\release\slamframe.exe:fatal error Lnk1120:8 an unresolved external command

The appropriate glut version could not be found and could not be resolved for the time being.

Correction Method:

2.1. Remove all #include "GlobalUtil.h" statements from the original SIFT project

This method is not desirable.

2.2. Log off all glut functions in GlobalUtil.cpp

Results:

The entire display interface is not available and therefore does not have to be used. The question of glut has also become a hanging problem.

However, it cannot be used and there is a problem during initialization, so the glut problem must be resolved.

Workaround:

The 64-bit version uses the 32-bit version problem.

32-bit version is very easy to find, a bunch of online, but the 64-bit version of the relatively difficult, more people said glut does not support the development of 64-bit, make a small dish once want to give up. Just as I was about to give up, a great God jumped up and said to me, Nani, who said no 64bit ....

Not much to say, directly to the URL: http://download.csdn.net/detail/knownall/6799947 This is glut3.7.6, which contains debug/release,32bit and 64bit.

Of course, you can choose to download the source code of their own compilation: http://download.csdn.net/detail/knownall/6799967 their own compiled should feel more cool, the side dishes is so do drip.

Use the 64-bit version of GLUT. Download Address: http://download.csdn.net/download/knownall/6799947
