计算车辆的方向(Veins/Omnet ++/Sumo) [英] Calculate direction of a vehicle (Veins/Omnet++/Sumo)

问题描述

是否可以通过TraCIMobility计算(获取)车辆的方向?我想知道两辆车是否正朝相反的方向行驶.我想我可以通过 getAngleRad()方法(如果它们沿相同方向移动，它们将落在同一象限中，如果它们沿相反方向移动，则它们将处于相对象限中)，但是我不确定它是否正确. (子问题:而且，getAngleRad()返回的确切值是什么? 每个象限?)

Is it possible to calculate(get) direction of vehicle in Veins(via TraCIMobility)? I want to know if two vehicles are traveling in opposing directions or not. I think I can do that via getAngleRad() method (if they are moving in the same direction they fall in the same quadrant and if moving opposite they are in opposite quadrants), but I am not sure if its correct. (Sub-Question: Also, what are the exact values that getAngleRad() would return for each quadrant?)

推荐答案

您是正确的:getAngleRad()以弧度(从-pi到但不包括+pi)返回车辆的航向.值0表示车辆正在向东行驶；值pi/2表示它正在向北移动；等

You are correct: getAngleRad() returns the vehicle's heading in radians (from -pi up to, but excluding, +pi). A value of 0 means the vehicle is heading east; a value of pi/2 means it is heading north; etc.
