However, current sensor based-solutions are not suited for the energy and computational needs of micro mobile robot systems. Like active sensors: IR Depth Camera, LIDAR, Radar. Whereas, DVS has low latency sensing and energy consumption are attractive for mobile robot collision avoidance. ...

Traditional camera systems use a frame-based approach, wherein a lot of the captured data is the same from frame to frame with typically only a few clusters of pixels changing values. This means that the sensor is constantly integrating the full field of view and sending the data from every...
Event-based Camera 中比较普遍的一类叫做Dynamic Vision Sensor(DVS)。 1. 对于单个像素点,只有接收的光强产生变化时,该像素点才会输出。比如亮度增加并超过的一个阈值,那么对应像素点将输出一个亮度增加的事件; 2. 实际上,传感器对亮度变化的响应不是线性的,而是对数的; ...
The image sensor may have pixels configured to output events indicating changes in sensed IR light. Those pixels may be sensitive to IR light of the same frequency source as an active IR light source, and may be part of an eye tracking camera, oriented toward a user's eye. Changes in ...
