Image-Free Positioning Tracking Scheme via Single Pixel Detection

AbstractAn image free positioning scheme using single pixel detection is proposed to improve the performance of positioning tracking. We use a bucket detector without spatial resolution to measure the light intensity, brings the merit of high sensitivity. The proposed scheme consist of the single pixel measuring step and positioning step. Firstly, we design the patterns of the digital mirror device and then get a sequence of measured scalar values. No image is reconstructed in this step. Secondly, by treating the vector of the bucket values as a virtual image, the image matching method is applied to get position of the object. This method significantly reduces sampling data in measuring process and complexity in matching process, which can be used for high-speed positioning tracking and image free guidance. Finally, a simulation case is performed to demonstrate the effectiveness. The results show the positioning tracking is achieved in a very low sampling rate.KeywordsImage-free positioningPositioning trackingSingle pixel detectionLow sampling
