Problems solved by technology

[0005] However, the traditional UWB positioning system and two-dimensional maps lack height information, and cannot reflect the height changes of positioning data, such as going up and down stairs, up and down slopes; there is a lack of correlation between multiple two-dimensional maps, and personnel positioning data is switched between two-dimensional maps. , lack of connection transition; the two-dimensional map has no obstacle avoidance function, and cannot correct the abnormal positioning of personnel caused by insufficient positioning accuracy, such as passing through walls

Embodiment Construction

[0093] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0094] The applicant believes that the traditional UWB personnel positioning system only displays the personnel positioning position on the two-dimensional map, but it is well known that the two-dimensional map lacks height information and cannot reflect the height change of the positioning data, such as going up and down stairs or uphill. At the same time, there is a lack of correlation between multiple two-dimensional maps, and when personnel positioning data is switched between two-dimensional maps, there is a lack of transition. In addition, there is no obstacle avoidance function on the two-dimensional map, so the positioning accuracy cannot be corrected, resulting in abnormal positioning of personnel, such as passing through a wall.

[0095] Therefore, in order to solve the above technical problems, the applicant combined ...

Abstract

The invention discloses a personnel positioning and three-dimensional visualization fusion method and a personnel positioning and three-dimensional visualization fusion system, and belongs to the technical field of Internet. The method comprises the following steps: 1, establishing a three-dimensional model; 2, preprocessing a navigation grid; 3, preprocessing a coordinate system; 4, receiving personnel positioning data; 5, reading personnel positioning data; and 6, processing personnel positioning data. According to the method, the positioning data is processed based on the navigation grid, the defect that UWB positioning cannot provide height information can be overcome, obstacles can be dynamically avoided, the refreshing frequency of the own three-dimensional personnel model position is lower than the refreshing frequency of personnel positioning data, and the performance overhead is reduced; and in combination with a personnel positioning data processing algorithm, the rationality, the real-time performance and the consistency of the positioning effect can be ensured.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a fusion method and system for personnel positioning and three-dimensional visualization. Background technique [0002] As an image symbol model to reproduce the objective world, the map can not only reflect the spatial structure characteristics of the cartographic object, but also reflect the changes of the time series, and can complete various evaluations through computer processing through the establishment of mathematical models, graphic digitization and digital models as required , forecasting, planning and decision-making. [0003] The function of map recognition includes the understanding of the spatial structure and time course change of the cartographic object through graphical analysis; the color shaded map of the cartographic object can be obtained through map measurement and analysis. [0004] To give full play to the function of map cognition, it is...
