PyKinectv2正文跟踪计数
PyKinectv2正文跟踪计数
提问于 2021-05-13 07:25:24
一般来说，pykinect和kinect都是新手--尝试简单地获取当前正在跟踪的身体的数量。不需要骨骼或关节数据。只是想得到当前帧中身体的连续计数。我使用的是kinect-v2和pykinect2。
更具体地说，我试图跟踪帧中有多少个物体，以及自该值更改以来所经过的时间。(0人对1人，1人对2人等等)由于pykinect的构建示例和它们循环的方式，这已经被证明是困难的。最新的尝试(现在使用已解决的代码进行更新)：

我发现了一个有用的代码片段，它可以在one of the examples provided in the PyKinect2 GitHub repo中完成您所需的工作。
您需要获取body frame，然后计算跟踪的body的数量：
kinect = PyKinectRuntime.PyKinectRuntime(PyKinectV2.FrameSourceTypes_Color | PyKinectV2.FrameSourceTypes_Body)
body_frame = kinect.get_last_body_frame()
n_bodies = 0
if body_frame is not None:
for i in range(0, kinect.max_body_count):
if body_frame.bodies[i].is_tracked:
n_bodies += 1
# n_bodies contains now the number of tracked bodies页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
