Problems solved by technology

The existing infrared-based indoor positioning methods and systems mostly use two-point positioning methods, which cannot measure the three-dimensional coordinates of the object, and only two-point positioning is performed, and it is easy to prevent the two infrared receiving terminals from Both receive infrared rays, resulting in positioning failure
In addition, the transmitter needs to transmit information such as infrared emission time to the controller through other transmission technologies such as radio frequency, which also increases the complexity of the positioning method and system

Abstract

The invention discloses an infrared-based indoor positioning method. The method includes that a moving transmitting end transmits modulation infrared, an infrared receiving end group receives the modulation infrared and transmits signal data to a controller, and the controller calculates position of the moving transmitting end according to the signal data. The invention further discloses an infrared-based indoor positioning system which comprises the moving transmitting end, the infrared receiving end group and the controller. The infrared receiving end group is connected with the controller and mounted according to a specific position relation. By adopting the method, three-dimensional position of a positioning object can be determined, and impact of obstacles on positioning can be reduced; transmitting information of the moving transmitting end is modulated into infrared, and the moving transmitting end does not need to communicate with the controller.

Description

technical field [0001] The present invention relates to an indoor positioning technology, in particular to an infrared-based indoor positioning method and system Background technique [0002] In an open outdoor environment, the Global Positioning System (Global Positioning System, GPS for short) can provide very accurate positioning information. However, in industrial and agricultural production, military and national defense, it is sometimes necessary to perform positioning and monitoring in an indoor environment. For example, accurate indoor positioning information is required in the environment of robots, mobile vehicles, security protection, and mine operations to achieve efficient spatial control. Compared with the outdoor environment, the indoor environment is affected by the building structure, internal layout and other artificial constraints, which have an impact on the accuracy and even effectiveness of the existing indoor positioning systems, such as GPS positioni...
