Photoelectric system method for rapid space-time positioning and attitude measuring

Abstract

The invention disclose a photoelectric system method for rapid space-time positioning and attitude measuring. The method comprises steps of constructing a photoelectric scanning attitude measuring system, constructing a GNSS reference positioning system, constructing a global positioning coordinate system, calculating coordinate parameters of an omnidirectional optical receiver, calculating a distance between a laser emitter and the omnidirectional optical receiver arranged around, obtaining optimal precise coordinate parameters of the omnidirectional optical receiver, constructing a coordinate matrix, obtaining a position of an object to be measured in attitude by rotating and moving the coordinate matrix evenly, and determining whether the obtained position of the object to be measured in attitude is correct. In the method, attitude is measured by using both the constructed photoelectric scanning attitude measuring system and GNSS reference positioning system, therefore, a problem that attitude measurement cannot be continued due to transient failure of the GNSS is solved, the object to be tested in attitude is guaranteed stable in rapid space-time positioning and attitude measuring, and a correctness determining module is used to determine whether the obtained position of the object to be measured in attitude is correct, so that the measurement result is guaranteed reasonable and accurate effectively.

Description

technical field [0001] The invention relates to the technical field of positioning and attitude measurement, in particular to a photoelectric system method for fast space-time positioning and attitude measurement.

Problems solved by technology

[0004] In response to the above problems, the present invention proposes a photoelectric system method for rapid space-time positioning and attitude measurement. By using the photoelectric scanning attitude measurement system and the GNSS reference positioning system to perform attitude measurement together, it can effectively avoid the inability to continue attitude measurement due to the short-term failure of GNSS The problem is to ensure the stability of the attitude body to be measured during the rapid space-time positioning and attitude measurement. At the same time, the measurement accuracy is high. By using the correctness judgment module to judge the correctness of the position of the attitude body to be measured, the accuracy of the measurement results can be effectively guaranteed. scientific and accurate
