近来，用于汽车的智能安全系统（例如，自主防撞）已经引起了相当大的关注。通常，汽车有距离传感器来检测障碍物。另一方面，动物和昆虫即使在未知的环境中也可以自适应地行动，即使它们没有这样的传感器。在生态心理学中，假设动物和昆虫使用与时间有关的信息来接触，而不是距离信息。这种接触时间信息被称为“τ-裕度”，在传统研究中，它是根据接近物体的表观大小及其时间变化计算出来的。因此，在计算τ裕度之前需要检测每个对象。在本文中，我们提出了一种算法来估计τ-边缘没有检测对象。为了验证所提出的算法的有效性，我们进行了实验，使用1/10比例的汽车和真实的车辆。
Recently, intelligent safety systems for automobiles, such as autonomous collision avoidance, have attracted considerable attention. Usually, automobiles have distance sensors to detect obstacles. On the other hand, animals and insects can behave adaptively, even in an unknown environment, even though they do not have such sensors. In ecological psychology, it is assumed that animals and insects use information related to the time to contact instead of distance information. This time-to-contact information is called the “τ-margin,” and it is calculated from the apparent size of the approaching object and its temporal change in conventional studies. Therefore, the detection of each object is required before calculating the τ-margin. In this paper, we propose an algorithm to estimate the τ-margin without detecting objects. To verify the effectiveness of the proposed algorithm, we conducted experiments using 1/10-scale automobiles and a real vehicle.
