Update: Installing OpenCV with Microsoft Visual Studio 2005 C++
98I have found I kept getting an error when I modified some of the example code.
The error message was:
C Run-Time Error R6034
Error Message
"An application has made an attempt to load the C runtime library incorrectly. Please contact the application’s support team for more information."
After trying a few of the suggested fixes I was starting to give up hope.
Luckly I found a post suggesting to change the configuration from debug to retail and recompiling.
It worked!
Installing OpenCV with Microsoft Visual Studio 2005 C++
149OpenCV stands for Open Computer Vision Library.
OpenCV is an open source library for computer vision development. There are some very interesting sample applications included with this library.
This sounds like the perfect start for Sir Bones.
Before we can start we need to be able to build the library.
Requirements
Optional
We are going to be using Microsoft Visual Studio for this install.
The reasons for this include Support from OpenCV, Lots of Internet Articles for creating software, MSDN, Offical Software and its FREE.
Step 1 – Installing Visual C++ and Platform SDK
Visit http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/ and follow Microsofts Guide to setup Visual C++ and the Platform SDK.
When you get to Step 3, add this line to "Include Files" (assume default install location)
C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Include\mfc
This is because OpenCV requires some files that are inside that folder.
Step 2 – Update Visual C++ with Service Pack 1 (Optional)
Service Packs for the each of the Visual Studio products are available on one page from Microsoft.
Visual Studio 2005 Express SP1
The specific update that you will require is called "C++ 2005 Express Edition SP1 – VS80sp1-KB926748-X86-INTL.exe"
Step 3 – Install OpenCV
Go get OpenCV Library and download OpenCV 1.0 for Windows
Installation is straight forward.
Step 4 – Customising Visual C++ for use with OpenCV
We need to setup the directories for Open Visual C++
- Open Visual C++
- Choose menu "Tools" and select "Options"
- In "Projects and Solutions" and go to "VC++ Directories"
- Show directories for "Library Files"
- Add "C:\Program Files\OpenCV\lib" to the list of directories
Step 5 – Open "OpenCV Workspace .NET 2005"
In the start menu a folder called "Open CV" was created when you installed OpenCV.
Inside the folder "OpenCV" there is a shortcut called "OpenCV Workspace .NET 2005"
Open "OpenCV Workspace .NET 2005"
This will load OpenCV solution within Visual C++
There is one last thing you need to do, to be able to compile OpenCV.
- Choose menu "Build" and Select "Configuration Manager"
- Change "Active solution configuration" to either "Debug" or "Release"
Step 6 – Build
Now that everything is installed and setup; building OpenCV should be a breeze.
- Choose menu "Build" and Select "Build Solution"
Building OpenCV can take anywhere from a few minutes to an hour.
When I built OpenCV it took about 10 minutes.< /p>
Congratulations OpenCV is now installed and built.
Useful trick for Notepad in Windows
108Have you ever wanted to record information in notepad and automatically have the date and time inserted?
Well now you can.
Open notepad and insert the following:
.LOG
Now save the document as <filename>.log
Also change the "Save as type" to "All Files", this is to prevent notepad saving the document as <filename>.log.txt
(Remember to replace <filename> with the actual name of the document you want to save as)
Now every time you open this document, the current date and time will be entered in for you.
Easy huh?
XBox 360 off for a while
98You see the oddest of things in the real world.
This message was seen on a XBox 360 during the Christmas Sales in Game store.
We are unsure as to the intent of the message.
Is it?
- Humour?
- Stupidity?
- or the Xbox is broken and they have no idea when it will be fixed?
Personally we feel it’s either option 1 or 3.
Featuring Sir Bones
100I have been looking everywhere for some realistic ears for Sir Bones. The idea of the ears is to channel forward sound in to the microphone; just like in the human body.
Trying to find realist ears is actually quite hard. Most of the ears available are novelty ears, over-sized and not very realistic.
I even went into a fancy dress shop to ask if they knew where I could get some, with no luck.
Recently I was shopping in Tesco's and I noticed this scary Halloween mask. The ears were almost perfect size for Sir Bones, so I could not resist buying this face mask.
The beginning
216I have been trying for a long time to understand computer vision, and trying to make a program that could pick out useful information from web cameras.
It was a standard set-up of 2 cameras and slight angles to each other, pointing forwards.
The trouble was they were free to move around. What was needed, was something to hold the cameras in a fix position.
The hunt for a human skull was on!
Sir Bones gets a (meek) voice
137Sir Bones has had a quiet life, constantly listening and not being able to say a word.
Today will change all that.
Sir Bones gets a voice (module).
All that is really needed is a speaker attached to a 3.5mm jack, but I prefer to have Sir Bones portable, so we'll be using a USB Sound card aka USB Voip Handset.
Give him a voice
97With the ability to hear and to see, Sir Bones is progressing very well.
Sir Bones needs to be able to communicate with the world around him.
What Sir Bones needs is a voice.
I have a voip handset, which is basically a USB sound card, which has a standard 3.5mm audio jack.
What I need now is to find a good enough speaker to fit inside Sir Bones, which is also loud enough to be heard.
We don't want him sounding weak now
