moving object velocity estimation 移动物体速度估计
Firstly, the shape moment features, size and velocity of each object are obtained through the segmentation of moving objects.
首先通过对运动目标的分割,分析得到各个物体的形状矩特征、面积大小及运动速度。
By the experiment of fixing static object and contrasting experiments of tracking moving object, the capability of the visual tracking system and the velocity PID control algorithm is tested.
并通过静态目标锁定实验和动态目标跟踪对比实验,检验了该视觉跟踪系统和速度反馈pid控制算法的性能。
The principle of the system is laser screen cutting: when the object moving laser screen, its velocity is gained using of acquiring optics flux.
该系统利用激光光幕区截原理:即当运动目标通过激光光幕时,采集光通量的变化从而获得运动目标的平均速度。
When you have a velocity in the moving plane frame and you want to find the velocity on the ground, you should add to every object in the plane the velocity of the plane with respect to the ground.
当你在运动的飞机上运动,然后你想找到相对于地面的速度,你就应该给每个物体加上,飞机相对于地面的速度
