From Wikipedia, camera resectioning is the process of finding the true parameters of the camera that produced a given photograph or video. Camera resectioning is also known as geometric camera calibration.
Currently I am using Camera Calibration Toolbox for Matlab for my camera calibration. The toolbox returns calibration parameters suc...
I have an image displayed on screen which is undistorted via cvInitUndistortMap & cvRemap (having done camera calibration), and the user clicks on a feature in the image. So I have the (u,v) pixel coordinates of the feature, and I also have the intrinsic matrix and the distortion matrix.
What I'm looking for is the equation of the 3D l...
Hi everyone,
I have a question about camera calibration. I've followed approach shown in a book Learning OpenCV for camera calibration process. But the calibrated(undistorted) image is worse than the original one.
Is it possible that my camera don't need calibration anymore?(means that the calibration is done by some driver or somethin...
Is there anyone who has used Point Grey's Bumblebee2 Stereo Camera? I need to know if anyone has calibrated this camera. Or if it's really needed to calibrate it. The fact is that I think its Image Center is not vaild and need to be calibrated.

Hi,
I'm testing my app on the AVD emulator ; one of the steps of my App is to take a picture ; when I get there, I get the right screen first (the one that has a take a picture and a Cancel buttons) but after a few seconds, before I can take the picture, I get this error message "The application Camera (process com.android.camera) has s...
Hello;
Basically, i want to write a windows form program like any other webcam's control program in c++ for a custom camera. this camera has some API like grab pictures and etc.
i have never done a camera application before, so i am a bit confused.
for the "preview" function like other webcam softwares, is it like just polling the...
Hi,
For my project i want to calibrate two cameras with CCV. in CCV, as i have seen, the camera is placed under a surface and blobs are detected from the surface. but in my project i want to detect blobs from over the surface one camera is placed on top of the surface(wall) facing the floor so it can detect the X coordinate other camera ...
