获得到ALVisionRecognition的代理

在一些初始化步骤之后，我们首先实例化一个到ALVisionRecognition模块的代理。

本测试展示如何使用ALVisionRecognition模块。

注释:

根据您的发行包不同，您可能没有这个模块。

  1. 我们初始化一个到ALVisionRecognition模块的代理。
    注释:

    该模块应加载到机器人的NAOqi上。
    模块将结果输出至ALMemory，在一个名为"PictureDetected"的变量中。
  2. 读取这一AlMemory值，查看是否获得有用的信息。

                # Create a proxy to ALVisionRecognition
                try:
                recoProxy = ALProxy("ALVisionRecognition", IP, PORT)

                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:

                # 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)
