Question

我正在尝试从用鼠标单击的像素中提取深度数据。当我打印X，Y坐标时，它可以工作。我尝试打印像素深度数据时它不起作用。Im尝试使用的代码是对如何为单击的像素提取RGB值进行的修改。我的问题是如何解析出要打印的深度数据。当我运行此命令时，我收到TypeError：'NoneType'对象无法下标有什么想法吗？

这是代码：

kinect = PyKinectRuntime.PyKinectRuntime(PyKinectV2.FrameSourceTypes_Depth)

while True:
    # --- Getting frames and drawing
    if kinect.has_new_depth_frame():
        frame = kinect.get_last_depth_frame()
        frameD = kinect.get_last_depth_frame()
        frameD = kinect._depth_frame_data
        #frameD = frame.astype(np.uint8)
        frame = frame.astype(np.uint8)
        frame = np.reshape(frame, (424, 512))
        output = cv2.cvtColor(frame, cv2.COLOR_GRAY2BGR)
        def click_event(event, x, y, flags, param):
            if event == cv2.EVENT_LBUTTONDOWN:
                print(x, y)
            if event == cv2.EVENT_RBUTTONDOWN:
                Pixel_Depth = output[x, y , 1]
                print(Pixel_Depth)
        #output = cv2.bilateralFilter(output, 1, 150, 75)
        cv2.imshow('KINECT Video Stream', output)
        cv2.setMouseCallback('KINECT Video Stream', click_event)
        output = None

    key = cv2.waitKey(1)

要使其正常工作，我必须指定像素编号，而不是“ frameD = kinect._depth_frame_data”的x，y坐标

这是代码：

FROM python:3

RUN apt-get update && \
     apt-get install -y openjdk-8-jdk-headless && \
    rm -rf /var/lib/apt/lists/*
ENV JAVA_HOME  /usr/lib/jvm/java-8-openjdk-amd64/

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY my_script.py ./
CMD [ "python", "./my_script.py" ]

pykinect2从单个像素KinectV2提取深度数据
