An Analysis Software for Visual Position and Attitude Measurement Algorithm

Visual position and attitude measurement (VPAM) system has been widely used in obtaining space target information. In order to better obtain different target information and meet the requirements, it is particularly important to select a correct and effective measurement algorithm. In this paper, a performance evaluation software of VPAM algorithm is designed, which can compare and analyze the accuracy and complexity of algorithms used by different VPAM models, and help users select appropriate position models to obtain more accurate target information. Finally, the software is verified by using the dual photogrammetric model in the shipborne helicopter landing system, and the validity of the analysis software is verified by comparing the calculation results with the theoretical value of the algorithm accuracy analysis. The main contribution of this paper is that, as far as we know, it is the first time to try to evaluate the complexity and accuracy of the algorithm by building analysis software instead of theoretical analysis.
