I am working on a project with: openCv, C++, and Kinect v1 and I am using the 3rd dimension in my work but the problem is that the kinect needs to be calibrated and I didn't find a way to do it simply ( especially that I don't have much time ) .
Is there any simple way to calibrate the kinect ? I really need it desperately.
PS: I already tried this code https://github.com/devkicks/OpenCVKinect it works just fine but when I use the openCv function: findCountour() I get errors with vectors.

I am new on using a Kinect sensor, I have Kinect XBOX 360 and I need to use it to get a real moving body 3D positions. I need to use it with c++ and openCV. I could not find anything helpful on the web. So, please if anyone can give me some advice or if there any code for opening Kinect XBOX 360 with c++ to start with I will appreciate that.
Maybe try this library: https://github.com/OpenKinect/libfreenect . If you don't have to use C++ obviously the C# drivers for the xbox Kinect by Microsoft are quite useful.
You're going to want to use OpenNI (https://structure.io/openni) for this. It will make your life infinitely easier. I believe you can even compile OpenCV with OpenNI support out of the box.
You'll probably also want to download and compile PCL (http://pointclouds.org/), which will make managing and manipulating the 3D data a lot easier.
To build a cohesive 3D "world", you'll want to use a fusion library like KinectFusion, which is actually baked into PCL already (https://github.com/PointCloudLibrary/pcl/tree/master/gpu/kinfu).
For object recognition, you'll want to use a classifier, of which OpenCV and PCL have many.
There are a plethora of tutorials and examples using the Kinect as an RGBD source.
I'm writing a program in opencv that stitches aerial images taken by a drone. The problem is that the stitch,after a certain point, start to "curving", so my homography matrix will be messed up and I can't stitch anything more.
There's a way in openv to do images orthorectivication without gps or DEM parameters? If not in opencv, there's a library easily integrable with opencv?
Thanks!
PS: I'm programming in C++
I have a really basic question in opencv and c++. I am trying to graph something in real time by using opencv. I am looking to find a function to draw a graph in rel-time. But still unssuccesful.
I need a function that gets two arrays as an input one for x axis and one for y. I tried with this but seems not work in real-time http://www.shervinemami.info/graphs.html
I just need to know if there is something available in opencv or not.
Thanks in advance.
OpenCV provides just low level drawing primitives, so you have to look for other libraries to plot chars, or create the code yourself.
I'm using OpenCV library (C++) to extract detectors from 2 images coming from a video stream taker from an aerial camera in order to, afterwards, find the matching points in successive images. i'm wondering which is the best algorithm to find robust detectors of a urban environment??
Ps. Actually I'm using SURF but when the images changes a little (because the camera is translating very slowly) the matchings between these descriptors become very few!
If you want to try different aproaches give a try to RoboRealm , they have a trial version, you just put the algoritms and seems the results, for testing purposes even if you will use OpenCV its ok.
I am new in opencv. I am trying to make a program which capture video from webcam and show the face on the video is exist in the directory or not. I already complete face detect from webcam. Now i jast need to compare the similarity of detected face with the directory image face. Please help me some one...
I am using
C++
MSVC 2010
OpenCV 2.1
You can use OpenCV's face detection methods. They have a very good tutorial in their website.
http://opencv.willowgarage.com/wiki/FaceDetection/
You can see to libface. It can detect and recognise faces.
