Lepton Web Streamer

[Anonymous Coward]

 

 

simple single threaded raspberry pi webserver for displaying streaming

output via firefox and chrome browser similar to a security

web camera but for the flir lepton module. (only single user)

 

Uses Mjpeg streaming which is semi-realtime (no streaming).

 

Does not work with Internet Explorer.

 

Once unzipped.

 

sudo python web.py

 

starts a listener on port 8080 of your pi.

 

Access via firefox

 

http://YourRaspberryIpAddress:8080 from your client machine (ie where your browser is located).

 

 

For chrome you will need to open the ChromeOnly.html and edit your

raspiberry ip address into it.  And then open the chromeonly.html from your desktop

as chrome needs additional help in working but it can work.

 

 

The exe's are compiled with

 

Raspberry pi b+ (512 meg edition) and left for your convenience.

 

Wiring of the lepton is /dev/spidev0.1 which is ce1 (pin 26) ?

 

Uses python and pil so you will have to have those installed.

 

For other Models of pi assumed you can just remake the source code from the sub directories.

 

/agcenable

/frame

 

run the command

 

make

 

in each of the above directories, should result in new compiled version for your particular pi version

 

 

Most of the code is original pure engineering with some glue logic.  The only real difference is agc

enable/disable in the Lepton_I2C.cpp module.

 

 

Im sure it can be made better but its food for thought.

 

 

Works well, allows me to walk around with nexus tablet and view output from battery

packed pi with wifi adapter.

 

You can resize automatically the image etc.  Means you no longer need an output

on the pi module as previously i was using a adafruit tft module.

 

 

 

Cheers and good luck.

Thank you so much for this! It is just what I needed and works great!

Thanks again - Steve

Hi there,

I am attempting to use your code but I think I am making some crucial error somewhere. I have run the make command in both of the .exe s you mentioned. However when I try to run the python code I just get the error that image does not exist. What am I missing? Do i need to move the python code somewhere else? Do I need to run the make files for the lepton code?

Any help would be much appreciated!!

Thanks,

Chris

the python script loops around running the frame.exe program which drops a file in your

/run/shm/  directory

called Numpey.dat


So in order to diagnose the issue

Run
sudo ./agcenable.exe

and then run

sudo ./frame.exe

then look in the directory /run/shm/ 

see if Numpey.dat file was created at this point.

If not try and determine why /run/shm dosnt exist.  Or tell me exact error message.

What version of pi are you running on ?

I probably had the same problem as Chris, I'm running on a pi 3. The directory /run/shm/ was not created automatically. Got this error:

pi@raspberrypi:~/webview $ sudo python web.py

Traceback (most recent call last):

  File "web.py", line 7, in <module>

    import Image

ImportError: No module named Image

Tried this and it worked:

sudo apt-get install python-imaging python-imaging-tk

Cheers

Have you check your wiring ?

Does it work with anything else ?

Is your lepton wired to /dev/spidev0.1

Anonymous coward!

Your work is very good!

However, it was a bit disappointing that it was impossible to use multiple threads using single thread.

So I modified the module you wrote a bit.

For the module you wrote, multiple connection was not possible because using a single thread.

So I modified the module a little using 'fork()' to enable multiple connections.

I hope my little contribution has helped someone.
