Hi community,
I write my own post processing pipeline but I get some ecto/ork errors. At this point I simply try to read my training-file from the database.
The error when I try to run my detection pipeline:
Traceback (most recent call last):
File "/home/marcel/catkin_ws/src/object_recognition_core/apps/detection", line 24, in <module>

My Trainer is working fine and it is also reading/writing some files from the database. I think the error is in my detection.py script.
This is my detection.py script:
from ecto import BlackBoxCellInfo as CellInfo, BlackBoxForward as Forward
from object_recognition_core.db import Document, Documents
from ecto_opencv import calib, features2d, highgui
from ecto_opencv.features2d import FeatureDescriptor
from object_recognition_core.pipelines.detection import DetectorBase
from object_recognition_colorhist import colorhist_detection
import ecto
from ecto import BlackBoxCellInfo as CellInfo, BlackBoxForward as Forward
class ColorHistDetector(ecto.BlackBox, DetectorBase):
def __init__(self, *args, **kwargs):
print "test0"
ecto.BlackBox.__init__(self, *args, **kwargs)
DetectorBase.__init__(self)
@staticmethod
def declare_cells(p):
cells = {'json_db': CellInfo(ecto.Constant),
'object_id': CellInfo(ecto.Constant),
'model_reader': CellInfo(colorhist_detection.ModelReader),
'detector' : CellInfo(colorhist_detection.Detector)}
return cells
@classmethod
def declare_forwards(cls, _p):
p = {'json_db': [Forward('value', 'json_db')],
'object_id': [Forward('value', 'object_id')]}
i = {}
o = {'detector': [Forward('pose_results')]}
return (p,i,o)
@classmethod
def declare_direct_params(self, p):
p.declare('json_object_ids', 'The ids of the objects to find as a JSON list or the keyword "all".', 'all')
def connections(self, p):
connections = [ self.json_db[:] >> self.model_reader['json_db'],
self.object_id[:] >> self.model_reader['object_id'] ]
# connections += [ self.model_reader['colorValues'] >> self.detector['colorValues'] ]
return connections
My very simple detection.ros.ork configuration file:
# info about the db
pipeline1:
type: ColorHistDetector
module: object_recognition_colorhist
parameters:
object_ids: "all"
db:
type: 'CouchDB'
root: 'http://localhost:5984'
collection: 'object_recognition'
In my understanding 'object_id': [Forward('value', 'object_id')] contains no valid data but I might be wrong.
I am working with Ubuntu 14.04 and Ros Indigo.
Thank you very much.
