I am a student who is currently working on a computer science project that will require soon computer vision and more specifically stereoscopy (for close depth detection). I am now looking for a great camera to do the job and I found several interesting options:
1- A custom built set of two cheap cameras (i.e. webcam);
2- The old, classic, economic and proven Kinect;
3- Specialized stereo sensors.
I found a couple months ago this sensor: https://duo3d.com/product/duo-mini-lv1
I tought it was interesting because it is small, stereoscopic and brand new (encouraging a fresh USA company). However, if we take apart the additional APIs that come with it, I just don't understand why you would buy this when a Kinect (or "cheap" cameras) are at least 4-5 times less expensive and still have great if not better specifications.
Same applies for this one: http://www.ptgrey.com/bumblebee2-firewire-stereo-vision-camera-systems
Can someone please explain to me why I would need such a device and if not, why they are needed for some?
