world coordinate

Establishing mapping relationship between image coordinate system and the world coordinate system, vehicle movement speed can be calculated.

然后，建立图像坐标系和世界坐标系的映射关系，根据测速原理，计算车辆运动速度。

The fundamental problem of the registration of the AR is the matrics transformation between the world coordinate, camera coordinate, image plane coordinate and pixel plane coordinate.

增强现实系统中注册的根本问题是世界坐标系，摄像机坐标系，图像平面坐标系，象素平面坐标系之间的坐标转换问题。

The graphics engine maintains the coordinates of geometric shapes in a path in world coordinate space.

图形引擎在世界坐标空间中维护路径内的几何形状的坐标.

A unique world coordinate based global calibration method with coplanar targets was proposed.

提出了一种基于共面点的世界坐标唯一全局标定方法.

Based on it, a new method is presented to obtain the world coordinate of target point, which provides much precondition for locating and tracing the object quickly.

在此基础上提出了一种恢复目标物体在世界坐标系中的三维坐标的方法，为实现对目标物体位置的快速判断和跟踪提供了有力的前提。
