Smart Camera (EagleEYE) based on CM3+

Thu Dec 05, 2019 11:41 am

Hi,

I am design Smart camera board and I would like to share the to commnity.

Please check the document from the Github link.

Hi,

Nice work, I'm working on the same idea. Few questions :
- Why did not you go with IMX219 for sensor ?
- Very nice enclosure, where did you get it ?
Custom board design based on RPI or other : http://www.aptustech.com/

The 5MP OV5647 was the first gen Pi camera.
The 8MP IMX219 Pi camera has a crypto chip on the PCB to stop cloning.

More pixels slows computer vision code down, often 300x300 pixel is enough.

- I think the 5MP sensor is enough for most of machine vision application and usually we did with Gray scale image 300px-600px only.
- the enclosure is custome made design for EagleEYE Smart camera.

As Gavinmc42 said, main argument is that ov5647 is clonable because of missing crypto chip. Sice Amomthep doesn't use a camera board but raw camera chip, imx219 is no option.

Another is price point, you can buy a v2 camera module for 25$, but a v1 camera module for 3$ incl. shipping on aliexpress.

@Amomthep:
You might be interested in a niche application of ov5647 sensor with raspivid, global (external) shutter capturing (needs bright flash):

1 second from 25fps video with 36µs strobe pulse duration, played at 5fps:

multiple exposures of fast moving object at daylight (five 9µs strobe pulse duration exposures, 116µs apart):

You can even capture airgun pellet in flight (109m/s) multiple times:

Actually the cryptochip is not required if you use the Compute Module :
https://www.raspberrypi.org/documentati ... -camera.md
Note for designers attaching Camera Modules directly to CM carrier boards: it is NOT necessary to incorporate the crypto chip used on the Raspberry Pi–designed camera boards when attaching the OM5647 or IMX219 Camera Modules directly to the CM carrier board. The Raspberry Pi firmware will automatically detect the CM and allow communications with the Camera Module to proceed without the crypto chip being present.
The IMX219 has of course better resolution, and from my understanding of both datasheet even with smaller cell size 1.12 vs 1.4 the IMX219 is more sensitive and has a better noise/signal ratio.
