论文摘要
本文提出将事件摄像机用作视觉系统的组成部分，该系统可以计算快速移动的对象 - 在这种情况下，掉落的玉米谷物。这些类型的摄像机传输了有关单个像素亮度变化的信息，其特征是潜伏期低，没有运动模糊，在不同的照明条件下正确操作以及功耗非常低。提出的计数算法实时处理事件。在由带有振动馈线的溜槽组成的台上证明了溶液的操作，这使得可以调节掉落的谷物数量。使用PID控制器控制系统的目的是保持恒定的平均下降对象数量。提出的解决方案进行了一系列测试，以确定开发方法操作的正确性。在他们的基础上，可以确认使用事件摄像头计算小型，快速移动的物体以及相关的广泛工业应用的有效性。
This paper proposes the use of an event camera as a component of a vision system that enables counting of fast-moving objects - in this case, falling corn grains. These type of cameras transmit information about the change in brightness of individual pixels and are characterised by low latency, no motion blur, correct operation in different lighting conditions, as well as very low power consumption. The proposed counting algorithm processes events in real time. The operation of the solution was demonstrated on a stand consisting of a chute with a vibrating feeder, which allowed the number of grains falling to be adjusted. The objective of the control system with a PID controller was to maintain a constant average number of falling objects. The proposed solution was subjected to a series of tests to determine the correctness of the developed method operation. On their basis, the validity of using an event camera to count small, fast-moving objects and the associated wide range of potential industrial applications can be confirmed.
