Getting a proxy to ALVisionRecognition

After some initialization steps, we first instantiate a proxy to the ALVisionRecognition module.

This test demonstrates how to use the ALVisionRecognition module.

Note:	You might not have this module depending on your distribution.

1. We instantiate a proxy to the ALVisionRecognition module.

   Note:	this module should be loaded on the robot's NAOqi.

   The module output its results in ALMemory in a variable called "PictureDetected".
2. We read this AlMemory value and check whether or not we get interesting things.

              

                import os
                import sys
                import time
  
                import naoqi
                from naoqi import *
                
                period = 1000
                moduleName = "Python_Reco"
                IP = "nao.local" # Replace here with your NAOqi's IP address
                PORT = 9559

                # Create a proxy to ALVisionRecognition
                try:
                  recoProxy = ALProxy("ALVisionRecognition", IP, PORT)
                except RuntimeError,e:
                  print "Error when creating ALVisionRecognition proxy:"
                  exit(1)

                # Subscribe to the ALVisionRecognition proxy
                # This means that the module will write in memValue with
                # the given period below.
                try:
                  recoProxy.subscribe(moduleName, period, 0.0 )    
                except RuntimeError,e:
                  print "Error when subscribing to ALVisionRecognition"
                  exit(1)
                
                # Let it run for 30 seconds
                time.sleep(30)
                
                # Unsubscribe from the ALVisionRecognition proxy
                try:
                  recoProxy.unsubscribe(moduleName)
                except RuntimeError,e:
                  print "Error when unsubscribing from ALVisionRecognition"
                  exit(1)
