All-wireless anti-interference positioning method and system based on edge calculation

According to the all-wireless anti-interference positioning method and system based on edge calculation, forward positioning and reverse positioning are carried out at the same time, the accuracy and anti-interference performance of positioning are improved through two-way cooperative positioning, coordinate information obtained through forward positioning and coordinate information obtained through reverse positioning are fused, multiple high-precision two-way fusion positioning coordinates are obtained, and the positioning precision is improved. And matching the multiple pieces of high-precision bidirectional fusion positioning coordinate information with fingerprint information in a high-precision bidirectional cooperative positioning fingerprint database, and determining a final high-precision bidirectional fusion positioning coordinate. In addition, supplementary fingerprints which do not meet the precision requirement are removed by utilizing the incidence relation between the core fingerprints and the
