具有垂直关节坐标的Kinect MATLAB问题 [英] Kinect MATLAB problem with vertical joint coordinates

问题描述

你好。

我正在使用kinect for windows v1和matlab记录骨架运动。经过大量测试后，我得出结论，水平坐标（x和z）具有良好的骨架/关节运动表现，误差小于±1 cm。
问题是垂直（y）坐标。在记录关节的两个静态位置时，MATLAB中收到的关节坐标显示与实际运动相比的大约一半的值。我认为它可能是传感器的倾斜角度使得b $ b有些问题，但是当将传感器倾斜到几个不同的角度时，结果是相同的。

有谁知道问题是什么？也许我应该将y坐标与一个因子相乘以使其正确。

祝你好运

解决方案

传感器是否完全没有倾斜，传感器没有遮挡地板？您需要校正传感器所处的任何角度。假设传感器平放在水平水平面上，并且您使用仰角
角度api来将传感器倾斜到适当的视图。

Hello.

I am using kinect for windows v1 with matlab to record skeleton movements. After a lot of testing I have concluded that the horisontal coordinates(x and z) have a good representation of the skeleton/joints movements with an error of less than +- 1 cm. The problem is the vertical(y) coordinate. The joint coordinates recieved in MATLAB shows about half the value compared to the real movements, when recording two static positions of a joint. I thought it could be the inclination angle of the sensor making some problems, but the result is the same when tilting the sensor to several different angles.

Someone who knows what the problem could be? Maybe I should just multiply the y-coordinate with a factor to get it right..

Best regards

解决方案

Is the sensor completely level with no tilt where the floor is not occluded from the sensor? You need to correct for any angle the sensor will be at. The assumption is the sensor is mounted flat on a level horizontal surface and you are using the elevation angle api's to tilt the sensor to the appropriate view.
