[Elphel-support] Simple Video processing with Elphel cameras

[Araujo, Leonardo]

Hi guys my name is Leonardo Araujo I'm a system developer at Sicpa. We
recently bought a NC353L camera and I could successfully get it running.
I don't know if you guys remember but I had to do some simple processing
(just run a threshold in a grayscale image) to measure the height of
products passing in front of the camera. A sample video of the system
running using a standard basler

Here is the source code of this height measurement system

Now our objective is to implement this process embedded in the Elphel
camera, our idea is something like that...

 

In the FPGA

1) Run the threshold filter

2) Extract a region of interest and place in some shared memory

 

In the processor

1) Get the shared memory and look for the most tall pixel.

2) Return this pixel coordinate through a socket to some PLC

 

The great questions are...

1) Where do we begin changing the FPGA verilog (Here we work with
Verilog and VHDL)

2) How do we compile things to run inside the camera  (Some kind of
crosscompile running in our machines and generating code inside the
linux 353 processor)

3) I've saw that future versions of Elphel cameras will use a different
processor, but you guys will st
