I have a number of Pis, each with a camera module attached.
I've mounted the cameras on a flat board side by side, but have discovered that there are physical inconsistencies in the camera modules manufacturing which cause them to point in slightly skewiff directions. I'm looking for ideas of to programmatically correct this via some sort of electronically controlled platform/bracket which can physically adjust the direction that the camera is pointing.
I've seen that there a full pan/tilt servo controlled brackets, but I don't need a full range of motion. I'm looking for something simpler, as it should only require 5-10 degrees of pan and tilt at most, and the cheaper the better.
I'm thinking there might be something out there which uses four pistons(one on each corner of a panel) to adjust direction, but I've been unable to find anything.
Can someone point me in the right direction if they are aware of anything like this, or even if you have other ideas for solving my problem.
On another note, once I do get this working, can anyone suggest a software/scripting solution that will help me calibrate the direction of the camera, say by evaluating a physical marker in the camera'f field of view?
Thanks in advance. Tim
