Kinect2的精度和准确度 [英] Precision and accuracy of Kinect2

问题描述

您好，

我可以问您Kinect2的精度和准确度是否已经过测试？我的意思是：

Can I ask you if the precision and accuracy of Kinect2 has been tested? I mean:

- 关节的实际位置与Kinect读取的距离之间的毫米距离

- the distance in millimeters between the real position of joints and the ones read by Kinect

- 实际取向之间的差异一个骨头和Kinect读取的那个...例如，我很想知道Kinect如何能够读取臀部和膝盖的屈曲 - 伸展以及躯干的正面/侧面屈曲......

- the difference between the real orientation of a bone and the one read by Kinect... for example, I would be very interested to know how the Kinect is able to read the flexion-extension of hips and knees and frontal/lateral flexion of the trunk...

我在等你的回复。

谢谢。

问候。

推荐答案

一般来说，在最佳情况下，你应该达到~5cm的准确度。最好的情况包括关节没有被遮挡，不靠近其他深度（靠近身体的手，靠近沙发等），并且用户面向传感器。对于某些姿势，准确度会降低
，最常见的是坐在远处向前倾斜，向前倾斜，向地面和侧向传感器。如果您需要更详细的信息，则必须自行进行更多测试。如果跟踪对您有效，您最好能够确定
。如果失败，您需要直接对深度数据进行自己的分析。 

Generally, you should achieve an ~5cm accuracy in the best case. The best case will include when the joints are not occluded, is not near other depth(hand near body, hand on sofa, etc) and the user is facing the sensor. Accuracy can degrade for some poses, the most common are sitting down leaning far back, strong forward lean, laying on the ground and sideways to the sensor. If you need more detailed information, you will have to do more testing on your own. You will better be able to determine if the tracking will work for you. In cases where it fails, you will want to do your own analysis of the depth data directly.
