碰撞时间(Time to Collision)检测 碰撞时间检测的目的是判断主车在行驶中与其他交通车的碰撞时间是否过小。 碰撞时间是指主车与引导车的相对距离除以主车与引导车的相对速度。 即使主车未发生碰撞,当碰撞时间过小时,发生碰撞的风险太大,这样也是不合理的。 当碰撞时间小于某一阈值(该阈值可用户自定义,本设计默认...

因此,从运动目标的图象序列中获取撞击时问的研究,对自动化技术和航天技术无疑具有重要的意义1Time—to—Collision估测的基本原理在导弹的惯性制导过程中,可以认为导弹作匀速运动.而且,由于撞击时间是在目标飞行过程中不断地宴时估计,而实时采集的图象序列中,由于采样时问间隔很小,在估计目标位于空间某位置的撞击时间...

Time-to-collision provides vital information for obstacle avoidance and for the visual navigation of a robot. The original contribution of this paper is to demonstrate with sequences of real images that time-to-collision can be robustly and accurately recovered with a single calibrated camera, using...
