Wide Angle Camera

Other Hardware Sensors
1

Hello all,
I'm looking for a camera I can hook up to an arduino, that can take a wide-angle photo - I need it to capture around 4 feet squared (1.2^2 meters) from a distance of around 30 cm. Quality of image is less important, I just want to see a large portion of a wall that is relatively close.
Is there such a camera (preferably OVM) that allows this at a reasonable price? I can't find the relevant details specified in the specs of any OVM camera..

Thanks!

Notwithstanding that an Arduino is useless for image transmission or manipulation, that is a pretty wide field of view.

Obviously specifying a camera's width by the size of the wall depends on how close you are to the wall. Lenses and cameras will have a field of view specified in degrees. This is corner-to-corner, like a TV or monitor is measured.

You can find online field of view calvulators that will turn your specification into degrees for you.

Thanks!
I just reached the same conclusion :slight_smile:

So after doing the amazing calculation of:

2 * [tan-1(0.6 / 0.3)] = 128

I suppose I need a DFOV of at least 128 degrees..

Is there a reliable camera for arduino that does that?
Gonna check in arrow, will try to supply answers myself.

Is there even such a thing as a "camera for arduino"?

Google is your friend.

A camera that you can comfortably hook up to an arduino, without extreme measures or black magic.

I have been to google, spoke to vendors, didn't find anything yet. Trying my luck with fellow makers.

typical Arduino cameras use 12MM X .5 threaded CCTV lens. these sell for chump change on eBay

typical Arduino cameras use a 6 mm lens as a normal lens. these lenses have a 10:1 ratio with 35 mm film camera lenses. an 18 mm is a fisheye lens on a 35 mm, a 1.8 has the same effect on CCTV cameras

1,7 & 1.8 mm: severe wide angle, no straight lines, massive distortion
2.1 mm : wide angle, a person can be identified on camera if you know him.
3.6 mm : slight wide angle, minimal distortion
6 mm: a normal lens. it shows what an eye sees
