The practical application of wireless positioning technology has attracted more and more social attention. Various researchers have a strong interest in the wide application of indoor positioning technology. RFID has many advantages, including non line of sight, high precision, low cost and wide transmission range. From the current development, RFID two-dimensional positioning method is gradually evolving to perfection and maturity. However, the research progress based on three-dimensional space still can not meet the current development and industrial application conditions. Based on the analysis of 3d-landarc positioning analysis model and related technologies, the performance of optimizing and realizing system positioning in the actual positioning process is improved under the condition of maintaining the same operation of system equipment
