如何避免胡椒机器人多次识别同一个地标？

Question

由于要开发一个模块来进行自我定位，我需要在Choreragphe中构建一个python框，这有助于避免Pepper机器人识别同一个地标更多次。原始地标只负责检测地标，但对同一地标重复该过程。 我的基本想法是建立一个字符串，其中包括已识别的地标的编号。但是在Choreragphe中，如果我们基于获取AlMemory模块的值来执行此操作，那么每当检测到地标时，不管它是否是新的，变量都会被刷新。（见图1） 此代码

class MyClass(GeneratedClass):
def __init__(self):
    GeneratedClass.__init__(self)
    #put initialization code here
    self.markIDs = []
    moreInfo = []
    self.memory = ALProxy("ALMemory")
    # Connect the event callback.
    # Get the services ALMotion & ALRobotPosture.
    self.motion_service = ALProxy("ALMotion")
    # Get the services ALTextToSpeech, ALLandMarkDetection and ALMotion.
    self.motion_service = ALProxy("ALMotion")
    self.got_landmark = False

def onLoad(self):
    self.logger.debug("Loaded box %s", self.getName())

def onUnload(self):
    #puts code for box cleanup here
    pass

def onInput_onStart(self, p):
    markIDs = []
    moreInfo = []
    # Generic Extractor output format:
    # p = [ [timeStampMaj, timeStampMin], [ tag0, tag1, ... tagN] ] with tag = [ shapeInfo, moreInfo ]
    if(len(p) > 0)&(not (moreInfo in markIDs)):
        self.logger.info("moreInfo in markIDs=")
        self.logger.info((moreInfo in markIDs))
        markInfoArray = p[1]
        self.logger.info("markInfoArray =")
        self.logger.info(markInfoArray)
        for markInfo in markInfoArray:
            moreInfo = markInfo[1]
            # moreInfo = [ landmarkID ]
            self.logger.info("markInfo =")
            self.logger.info(str(markInfo))
            self.logger.info("moreInfo=")
            self.logger.info(str(moreInfo))
            if not (moreInfo[-1] in markIDs):
                self.got_landmark = True
            markIDs.append(moreInfo[-1])
            self.logger.info("markIDs =")
            self.logger.info(str(markIDs))

    self.onStopped(markIDs)

返回此结果：

但是如果我们单独在一个python脚本中这样做，然后将其导入到choregraph，那么在那一点上，有人建议我遵循的Github项目中的工作流埃米尔先生，robot-jumpstarter我尝试过，但在编舞中没有成功。你知道吗

因此，是否可以在choregraph中（如picture3中）执行一些与Naomark模块并行的本地python脚本，以将检测到的MarkID保存在其中，以此类推？

Answer 1

我可能没有抓住困难，不管怎样，解决起来似乎很简单： 添加一个连接到DetectLandmark输出的框并执行以下代码：

def onInput( self, p ):
  if p != self.last
    self.last = p
    self.output(p)
