The present invention discloses a positioning system and method relating to positioning technique. The positioning system includes a transmitting end and a receiving end. The transmitting end includes a controller and N signal transmitters, wherein, N is a natural number larger than or equal to six. N signal transmitters are divided into two groups, each group includes at least three signal transmitters. The controller controls the two groups of signal transmitters to transmit pulse signals to the receiving end according to a pre-set time sequence. The receiving end includes a signal receiver and a signal processor. The signal receiver outputs received pulse signals to the signal processor. The signal processor acquires position information of the receiving end according to the received pulse signals. In comparison with the prior art, the controller of the transmitting end is used to control the two groups of signal transmitters to transmit the pulse signals to the receiving end according to the pre-set time sequence, the receiving end processes the received pulse signals, and then position information of the receiving end is acquired. Therefore, the receiving end is positioned according to the change of the pulse signals so that the receiving end positioning is more precise.
Description
technical field [0001] The invention relates to positioning technology, in particular to a positioning system and method. Background technique [0002] At present, the positioning accuracy of visible light positioning technology, especially in the field of indoor navigation, is generally not high compared to the existing commonly used positioning technologies. [0003] For example, for a visible light positioning system using an Arrival Of Angle (Arrival Of Angle, AOA for short) technology, this technology determines the angular relationship of the target relative to the signal transmitter according to the angle of arrival of the signal. Specifically, the detector array is used to calculate the angle between the LED light (signal transmitter) and the target (signal receiver), and the position of the target is calculated based on the calculated angle between the LED light (signal transmitter) and the target (signal receiver) , however, this technology is very sensitive to th...
