646425b2a6 Add color thresholding support to get_histogram/stats.
You can now pass a color threshold list to get histogram and get stats
(along with an invert arg) to control what gets put into the histogram.

11983a0228 Add wifi_dbg stub.
All the notes about how to implement wifi programming are in the code.
Steps:

1. Get wifi_apply_settings() working first and make sure you can turn
the wifi shield on in the right mode. Then add the necessary hooks into
the network code to make it such that previous user wifi code still
works. Also, make sure to handle start and shutdown gracefully.

Basically, get all the lifecycle code working first before moving to the
next step so notning gets in a weird state and bugs creep in...

2. Get the beacon method working. Once this works OpenMV IDE should see
the camera when you hit the connect button.

3. Do the code to turn off the regular usbdbg interface and swtich to
having the data come from wifi_dbg. This isn't a lot of code... but,
will be tricky since you no longer will have USB frames to work with.
All bytes are just going to come randomly and in bursts so you have to
handle the serial stream yourself... (Kwabena can help writing a
statemachine for dealing with this type of stuff if you want. I do it
all the time).

Add single image shadow remover code.
2018-01-29 18:03:25 +02:00
Kwabena W. Agyeman
5377f6f575 Add single image shadow remover code.
Calling remove_shadows() on an image without a background source of
truth image now works. However, that said, the shadow remover isn't
suitable for anything other than removing shadow on an image of concrete
flow or somthing of the like. In general, it can only remove shadows
from a scene that has nothing else in it except for a hard edge shadow.

Improving this to work for anything is about a month of work. I've
researched enough about shadow removal to now know the optimal way to do
it. However, it requires many steps and a large amount of RAM. On the H7
I may revist this as being possible.

...

In order to get the shadow remover working well I had to add a few
features to the image library and fix some of the convolution code.
These fixes will likely be more useful than the shadow removal code.

Note the addition of the new get_threshold() method. This computes
otsu's threshold on a histogram allowing you to pick the optimal color
bounds.

Add REPL Uart Ini File Setting Support
2018-01-23 19:00:16 +02:00
Kwabena W. Agyeman
bfcdcd4793 Add REPL Uart Ini File Setting Support
OpenMV IDE includes an ini file generator which will let you set board
settings easily from the IDE. Currently, the IDE has support for setting
the WiFi shield up along with adding a REPL Uart.

Anyway, this commit adds support for the OpenMV Cam to parse an ini file
on startup to configure things before starting main.py. WiFi support is
not yet implmented. However, we now have the ability to turn the UART
and put the REPL terminal on it on startup given a setting in the ini
file.

(Why not use boot.py like normal MP? While that is more flxible it's
much harder for the IDE to easily write out settings for you which is
what most users will want to do versus coding this up).

...

The movitation for adding REPL UART support in particular is so that the
OpenMV Cam can be used as a slave processor to IoT type processors like
the ESP32/ESP8266/ParticlePhoton/ElectricImp. In particular, a processor
like the ParticlePhoton can control the OpenMV Cam's reset wire. Wake
the camera up by releasing reset, then send a script to it after it
powers on over the UART. The camera will then run the script, do
computer vision, and report results back over the UART to the
ParticlePhoton. Users can then push new scripts to the OpenMV Cam from
the cloud allowing for semi-flexible firmware fixes for the OpenMV Cam
over low data rate networks.

By setting this feature up the need for OpenMV to offer a WiFi IoT
system is reduced as we can now just be the best camera for everything.

...

Due to... I don't know... ctrl-c doesn't work on the duplicated UART.

https://github.com/micropython/micropython/issues/1568

Not sure how to handle this. I don't want to fix it since it needs to be
fixed by MP upstream. Right now the work around is for the mastering MCU
to just reset the OpenMV Cam when it's done with the system.

That said, this does mean that once you start a script using the Open
Terminal command line system you won't be able to stop the script.

fc9c416a21 Frame Differencing with Shadow Removal
Add in support for shadow removal from the current image using a shadow
free background image. Test results show the algorithm works similar to
max() while still keeping dark objects around. The preformance impact of
the algorithm is not too high. An in memory example can achieve 30 FPS.

c78f91b421 Phase Corr Redo 2
Redid the phase correlation code again so it's one method call now. This
method call can either do logpolar phase correlation to get rotation/
scale or translation(x/y). Additionally, it will be able to also do both
at once. However, I don't have that quite working yet.

I've updated the example scripts to reflect the new code too.

Finally, I had to fix a bug in the rotation correction code.

...

Once I've got the full pipeline working I will post scripts for that. I
have all the code in there and it's been somewhat debugged... However, I
can't get a useful phase correlation lock out of the log polar fft mag.
I plan to look into noise filtering and spectral whitening solutions for
this.
