我需要什么样的参数来发送这个功能让它工作我有点像菜鸟
def TransformSmoothParameters(vPoint):
"""returns depthX (float), depthY (float), depthValue (int)"""
if vPoint.vector.z > _FLT_EPSILON:
# Center of depth sensor is at (0,0,0) in skeleton space, and
# and (160,120) in depth image coordinates. Note that positive Y
# is up in skeleton space and down in image coordinates.
#
pfDepthX = 0.5 + vPoint.vector.x * _NUI_CAMERA_SKELETON_TO_DEPTH_IMAGE_MULTIPLIER_320x240 / ( vPoint.vector.z * 320.0 )
pfDepthY = 0.5 - vPoint.vector.y * _NUI_CAMERA_SKELETON_TO_DEPTH_IMAGE_MULTIPLIER_320x240 / ( vPoint.vector.z * 240.0 )
#
# Depth is in meters in skeleton space.
# The depth image pixel format has depth in millimeters shifted left by 3.
#
pusDepthValue = int(vPoint.vector.z * 1000) << 3
return pfDepthX, pfDepthY, pusDepthValue
return 0.0, 0.0, 0
某种阵列?它会是什么样子?
答案 0 :(得分:3)
好像你需要将一个对象传递给该函数。然后,该对象具有名为vector
的数据属性(这是另一个对象),该属性具有数据属性x
,y
和z
下面的伪代码可能会更清晰:
class vPoint:
def __init__(self, vector):
self.vector = vector
class vector:
def __init__(self, x, y, z):
self.x = #the x value
self.y = #the y value
self.z = #the z value
这样,您可以使用代码中指定的x
访问vPoint.vector.x
值。
