摘要：
Aiming to fix the data loss problem of optical camera communication (OCC) data link resulted from the lack of sync between the camera and the LED signal lamp, as well as the gap time between every two consecutively captured pictures, the fundamental principle of LED-camera based OCC data link, camera parameters like pixel row number, pixel read out time, frame rate and shooting angle are analyzed in detail in this paper. Based on the characteristics of the OCC data link, a new data frame structure is proposed in this paper. When compared to the related data frame structure like interleaved Hamming coding and Raptor coding, the proposed date frame structure has a higher data transmission rate, and has the capability to fix both the inter-frame and intra-frame data loss problems. Numerical and measurement results both prove the validity of the theoretical analysis, finally. © 2021, Chinese Institute of Electronics. All right reserved.
