视角 [英] Viewing angles

问题描述

我想估计Kinect深度传感器捕获的物体的垂直/水平范围。

视角为43度垂直和57度水平（如编程指南中所述，第11页），适用于彩色摄像机和深度摄像机吗？

深度流像素在整个视野范围内的分布是否均匀？

计算320x240深度图像中90x76像素区域的大小，距离Kinect传感器1124 mm，我可以很好地估计水平分量（2-3内） mm），但我对垂直分量的估计偏差30 mm
（太小）。

祝你好运，

解决方案

也许  SkeletonEngine.DepthImageToSkeleton方法会解决您的问题吗？此方法精确地用于将深度图像像素{pixelX，pixelY，以毫米为单位的深度}映射到以米为单位的实字坐标{x，y，z}。

I would like to estimate the vertical/horizontal extent of objects captured by the Kinect's depth sensor.

Do the viewing angles of 43 degrees vertical and 57 degrees horizontal (as mentioned in the Programming Guide, p. 11), apply to both the color camera and the depth camera?

Is the distribution of depth stream pixels uniform across the viewing field?

Computing the size of a 90x76 pixels area in the 320x240 depth image, at a distance of 1124 mm from the Kinect sensor, I get a good estimate of the horizontal component (within 2-3 mm), but my estimate of the vertical component is off by 30 mm (too small).

Best regards,

Jesper

解决方案

Maybe SkeletonEngine.DepthImageToSkeleton method will solve your problem? This method is precisely intended to map from depth image pixels {pixelX, pixelY, depth in millimeters} into real-word coordinates {x,y,z} in meters.
