Re: binning example
Hello All ,
Have a small doubt it would be great if you help me .
here it is i have an error while running a code this is the error
There is a make file also which i have included.
Also i have tried putting vision.so into
usr/lib
and again did
make clean
and make
But still doesnt help
PYLIB = /usr/bin
PYINC = /usr/include/python2.7
all:: vision.so
vision.so: vision.o fireflymv.o image.o
gcc -shared -W1 -ldc1394 -L$(PYLIB) -lpython2.7 -o vision.so vision.o fireflymv.o image.o
fireflymv.o: fireflymv.c fireflymv.h
gcc fireflymv.c -c -fPIC -o fireflymv.o
image.o: image.c image.h
gcc image.c -c -fPIC -o image.o
vision.o: vision.c
gcc vision.c -c -fPIC -I$(PYINC) -o vision.o
clean:
rm -f vision.o image.o vision.so fireflymv.o *.pyc
error
import vision
ImportError: /home/cfc/workspace1/test/vision.so: undefined symbol: dc1394_video_set_mode

Binning is not a feature of IIDC, so vendors usually use different
Format_7 video modes to implement it. The maximal size of a 'binning'
video mode will thus be only half the maximal size of a normal mode.
Example:
F7M0: max size = 1280x1024
F7M1: max size = 640x1024 (horizontal binning)
F7M2: max size = 1280x512 (vertical binning)
F7M3: max size = 640x512 (full 2x2 binning)
Which mode corresponds to which binning depends on the model so
ultimately you'll have to check the camera docs to be sure.
To start using binning you just put the camera in the proper format_7
video mode and start capturing.
