我们开发了一种像素并行图像处理算法，用于检测和跟踪时间调制光信号，用作光学ID标签。该算法不需要波长滤波器，在解码传输数据的同时以高帧率获得信号的位置信息。我们实现了所提出的算法在数字视觉芯片，像素并行处理器嵌入在CMOS图像传感器，并证明了它是可行的。
We developed a pixel-parallel image processing algorithm for detecting and tracking temporally modulated light signals for use as optical ID tags. The proposed algorithm requires no wavelength filters and obtains position information on signals at a high frame rate while decoding transmitted data. We implemented the proposed algorithm in a digital vision chip, a pixel-parallel processor embedded in a CMOS image sensor, and proved it to be operationally feasible.
