hi everyone, i am experimenting on 3D reconstruction from different 2D views.we have 5 camera's at different angles(nearly 35 degrees apart in the form of a semicircle). I need to calibrate them. Can i directly calibrate the parameters by using these images or i have to use checker board pattern. I am using matlab R2013 version. In that i dont have camera calibration toolbox. So can i get the parameters by using code? I appreciate if anyone could help me out figuring how to do this. Thanks and best wishes.

You can calibrate the cameras one by one using a checker board pattern, which is the easiest method in my opinion. The process is very simple: first you have to load calibration images (capture the checker board pattern with the camera you want to calibrate), then you have to manually extract image corners, run the main calibration engine and finally you get the results.
If you don't have access to the camera calibration toolbox, I recommend you to use Caltech's algorithm. Here's the link: Caltech Camera Calibration
Hope this information helps.
