Method for improving light source authentic identification accuracy based on classification in visible light positioning

The invention provides a method for improving light source authentic identification accuracy based on classification in visible light positioning, and belongs to the technical field of navigation positioning. The method comprises the following steps: firstly, obtaining an authentic identification result through a vector product-based chiral authentic identification method; secondly, a classification step is added after an authentic identification result, and the result of the authentic identification algorithm is processed and classified; and finally, correcting the authentic identification result. In the classification step, a light source imaging coordinate and an algorithm error probability are used as classification standards, and chiral authentic identification results are divided into a class with high credibility and a class with low credibility; if the light source array is classified into a class with high credibility, trust chirality of an authentic identification result can be realized; and if the
