Ubuntu :: Shell Script For Opencv Compilation?
May 30, 2010
I installed Opencv in Lucid.But i dont know how to compile a program (.c/.cpp) by giving additional opencv flags. So i found another method, There is Buildall.sh (given Below) along with the samples in Opencv Source.I copied buildall.sh to my working directory and using it but there is a problem that each time it compile all the source files in the .
But what i need is a "build.sh" file such that it compile only the argument file given from terminal using opencv flags as in buildall.sh. like follows
Code:
sh ./build.sh prog.c
then it will compile prog.c
Code:
sh ./build.sh prog2.cpp
then it will compile prog2.cpp
its for my project .imy entire project using opensource tools and softs only. if possible somone pls explain the shell script in build all.sh
[Code]...

I'm using a logitech quickcam pro 3000 on Ubuntu 10.04.
When I run a simple program with OpenCV to display the output from a camera I get the following output:
Code:
A window still opens with the output from the camera, but it seems very low quality and has far less pixels then it should. The camera built into my computer runs the same program with no problems.
My code for the program is simply:
Code:
One further note to make is that I still have the bad quality and low number of pixels with the logitech even when using webcam program. I can seem to find any drivers to update or anything though.

I need to run Opencv 1.1 or lower to be compatible with the systems at my University where most of my work is done. 9.10 allowed 1.1 through apt, but before that I remember all kinds of nightmares getting OpenCV to run with FFMPEG. If I go back to self-installing 1.1, am I going to have a repeat of those nightmares? I guess a better way to phrase it, is there any way to get opencv 1.1 through aptitude?

I'm starting to use Ubuntu 10.04 LTS and want to install a Java based language, Processing which uses OpenCv library to perform video issues. [URL]. I'm not familiar with the terminal but willing to be. I'm also not familiar with the file system, I mean I don't exactly know where the archives downloaded are and where they should be to be executed.

I am learning image processing and hence using opencv-2.2.0. I am following the link [URL] to install this. But even the first command to install build-essential.
Code:
apt-get install build-essential
is giving following errors...
Code:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may resolve the situation:

I recently installed openCV using [URL]. I am unable to locate library location to be included while running programs. Does this version of openCV needs libraries to be downloaded externally or they are inbuilt and I am unable to get their location.

I am trying to compile OpenCV 2.0 with ffmpeg (with x264) support on my Ubuntu 11.04 64-bit machine. (Since I want to use the binaries provided by other developers, I have to use opencv 2.0 version)
I followed the guide from: [URL] to compile x264 and ffmpeg manually, and succeeded.
Then I followed the guide in the INSTALL file provided by the OpenCV 2.0 package. I use CMake to configure and generate them, and use "make" command to try compiling. However, I got the following error report, which haunted me for almost half a week.
Code:
Linking CXX static library ../../lib/libhighgui_pch_dephelp.a
[ 71%] Built target highgui_pch_dephelp
Scanning dependencies of target pch_Generate_highgui
[ 71%] Generating _highgui.h

I've introduced myself to OpenCV a bit now and can do some of the most basic things with it. My current goal is to have a solid color object (say a red ball) and have a camera be able to find that object. Anybody know of any resources to start learning how to do this? Any tutorials/books? Or is there something I should be searching for instead of color detection and tracking that will give me things more in the right direction?

OpenCV doesn't work. I wonder why would anyone create a RPM package and not bother to check whether it actually works? Do they get paid per package at Red Hat? The problem seems to be in cap_ffmpeg.cpp. Somehow, OpenCV cannot resolve the ffmpeg CODEC libraries, but the annoying part is that it compiles and installs error free - it just doesn't work. Without any error messages, it is really hard to figure out what is wrong.

I've a question regarding two camera images. Suppose I've detected 2d window coordinate of 8 markers of an object in a scene in one camera and detected window coordinates of 10 markers of the same object on another camera.
I've detected the marker. It was easy. Now how do i know which window coordinates on two cameras are the coordinates of same marker? I mean there are markers captured on both cameras and some of them are representing the same marker in both cameras. I just like to know which ones are same on both cameras. Is it possible to find that out using opencv?

I'm trying to compile a fortran code (not my own and I don't know fortran well) and have been having some trouble as the compilation starts and then fails as the computer completely freezes (as in press power button freeze). I added 1.5Gb swap memory as the computer only has 1GB and then tracked the memory use as the process happened and it seemed that the swap wasn't even used. The memory usage hit 90% of the 1.Gb and the machine froze again. The compiler is gfortran
