摘要
公交车辆是按固定路线行驶运营的,运营信息具有一维线性分布的特点,因此提出了一种新的公交车辆监控的一维图形显示方法。该方法采用一维坐标系的数据模型描述和绘制监控场景,通过相对定位方式标定车辆位置。最后,以实例说明了该方法在公交车辆监控子系统中的应用。
Buses mn on the fixed line and the distribution of information is one - dimensional. Presents a new one - dimensional graphic display method for bus monitoring. In the method, representations and drawing of monitor scene used data model of one- dimensional coordinate system, and buses were located by relative location. The application of the method in the bus monitoring sub - system is illustrated.
