IMX219-83 Stereo Camera Waveshare

Post by JtLadD »

This is very interesting to me as I already 8-) have a Leica BLK3D which is essentially the same with the addition of a laser distance metre which measures the distance to the approximate (?) centre of the image. This gives scale and orientaion of the pairs.
One other thing about the BLK3D that I do not yet see from Stereopi users is that the cameras are offset both horizontally and vertically which I think helps with the stereo computation.

Hi JtLadD,
Actually, when you have both horizontal and vertical offsets, it is similar to rotating horizontal offset at some angle. But your images should be rotated too. :-) I don't think that basic OpenCV calibration procedure will manage this out, but I'm curious to try this.
You see, "double axis offset" useful for detection of a disparity for horizontal lines (which are mostly invisible by horizontal offset), and also gives you some more distance between cameras (stereo base), as it is a diagonal size of a rectangular setup.
As for IMX219-83 (mentioned in our last update) - we are waiting for delivery of this item to test it. It looks interesting, as it is cheaper than a couple of camera modules, but also has additional features (like IMU) onboard. Also it has a relatively small FOV 83/73/50 degree (diagonal/horizontal/vertical). I will try to replace optics to wide angle, as used optics looks like a classic M12.
