角度（步进电机）和距离（Kinect）之间的关系？ [英] Relationship between angle (Stepper motor) and distance (Kinect)?

问题描述

您好我正在做一个项目由步进电机和Kinect组成。我希望步进电机根据Kinect认可的
身体关节的距离旋转。我想一直在一个人的左手上投射激光指示器。如果此人离相机更远，步进电机会以激光点在手上的方式移动。

解决方案

Kinect将不了解您的外部系统，您必须开发它的工作方式。 Kinect Skeleton跟踪api将为您提供距离传感器在"世界空间"中的联合距离。以米为单位。每个骨架对象都有一个位置
属性，它将为您提供该人的中心（最多6个）。如果您想了解特定的关节细节，可以获得最多2个完整的关节信息。请参阅SDK Toolkit浏览器中的骨架跟踪示例（Skeleton Basics，Kinect Explorer等）

Hi I am doing a project consisting of a stepper motor and Kinect. I want the stepper motor to rotate according to the distance of a body joint recognised by Kinect. I wan to cast a laser pointer on the left hand of a person all the time. If the person goes further away from the camera, the stepper motor moves in a way that the laser dot is at the hand.

解决方案

Kinect will have no knowledge of your external system, you have to develop how that would work. The Kinect Skeleton tracking api's will provide you the joint distances from the sensor in "world space" in meters. Each skeleton object has a position property that will give you the center of the person(up to 6). If you want to know specific joint detail, you can get full joint information on up to 2. See the skeleton tracking samples in the SDK Toolkit browser(Skeleton Basics, Kinect Explorer, etc)
