一般来说，在***情况下，你应该达到~5cm的准确度。***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***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.
