Camera for vision

Hey! For the IR@Home challenge, we are currently using a Microsoft 3000 Lifecam for target vision (reflective tape) detection. However, this camera doesn’t seem to have a good enough field of view, so it either can’t see the target from the back or the front. We need the full range of the field visible to the camera for the Interstellar Accuracy Challenge.

Does anyone have any camera recommendations?

This one has worked decently well for us in the past for purposes of wide-angle image capture.

Framerates and latency can sometimes cause issue, depending on what you’re attempting to do. Raspberry Pi -based solutions seem to be the new standard in “best” for 2021. Good news, they offer multiple good camera modules that are fairly plug-and-play.

The Limelight(https://limelightvision.io) has been fantastic for my team. A bit expensive but well worth it in terms of ease of use and performance imo. An alternate approach could be using an adjustable camera mount, some teams mounted theirs to an adjustable hood last year.

We use the Microsoft 3000 Lifecam rotated 90 degrees to get about 20 feet of range from near to far from the high port. You can even get the distance from the port to the camera by the placement of the image in the frame. One of our students designed a really nice camera and LED holder with the correct angle to mount it on the turret.

I’ve been having trouble with mounting a life cam stably enough for vision and would love to have a look at this, is there any chance you’d be willing/able to share CAD?

I asked the CAD team if they had a file to share; we’ll see. The head student is very busy with drawings for all the competitions and his school work keeps interfering, too. Attached files are photos I just made for you of a prototype we used for vision testing that is close to the final product. Notice the little catches on the front left and right, and the little springy things are almost discernable on the front top and bottom.

The bare LED shown is like what’s inside (except we do use green not orange that I grabbed to show you). The heat sink might be optional since we run the LED highly derated (we didn’t know that they were so bright early on) but we’re now committed to it as a required spacer so it all fits together tightly.

The gray light shield keeps a lot of stray light out of spectators eyes.

That’s really helpful, thanks so much!

Here’s the actual CAD if it helps. Wish we could take full credit for it but we got our start from another share, then our student modified the mounting and added the LED frame. Let me know if you have any trouble with the link
