Method, device and electric apparatus for obtaining object position information

Abstract

The embodiment of the invention discloses a method, a device and an electric apparatus for obtaining object position information. The method includes the steps of: in a transmission period, receiving signals transmitted by an antenna array in the object in turn, and calculating various received signal strength indications, wherein the transmitted signals include antenna array information; selecting a first antenna mapped by the received signal strength indication satisfying a pre-set first selection strategy, and extracting a second antenna and a third antenna adjacent to the first antenna; selecting the received signal strength indication satisfying a pre-set second selection strategy from the obtained received signal strength indications mapped by the second antenna and the third antenna, and obtaining an auxiliary positioning antenna; and obtaining the position information of the object relative to the electric apparatus which receives signals according to the first antenna, the auxiliary positioning antenna and the antenna array information. The positioning precision of the object can be improved by applying the method, the device and the electric apparatus for obtaining the object position information.

Description

technical field [0001] The invention relates to positioning technology, in particular to a method, device and electronic equipment for acquiring position information of an object. Background technique [0002] With the continuous development of computer communication and Internet technology, the application of electronic devices is becoming more and more common. For example, smart mobile phones, personal digital assistants, palmtop computers and desktop computers are more and more widely used. For example, taking the positioning application as an example, on the one hand, the application program (APP, Application) installed in the electronic device can be used to locate and navigate the electronic device through the interaction with the base station and the navigation system, thereby guiding the user of the electronic device The user arrives at the destination on the electronic map along the navigation route. On the other hand, the application is to build a positioning syst...

Problems solved by technology

[0003] However, the method for obtaining the position information of the target uses the distance R between the electronic device and the vehicle calculated by the received RSSI signal, and the obtained position information (positioning information) is only the distance information, and cannot provide the orientation information of the electronic device and the vehicle. Searching within a circle with a radius of R makes it take a long time to search for the target, especially if the target is in a moving scene, the search is performed along a circle with a radius of R, if the direction of the search is Inconsistency with the orientation of the target may cause the distance between the target and the electronic device to become larger and larger, resulting in lower accuracy of positioning the target by this method
