In addition, when the object to be determined moves in multiple sub-positioning spaces, due to the scanning angle of the positioning light tower and the erection position, there may be a positioning blind area in the red edge area of the sub-positioning space. When the object to be positioned moves to the blind area , the optical signal receiver set on the object to be positioned may not receive the positioning signal emitted by the positioning light tower in the sub-positioning space where it is located. The positioning signal sent by the positioning light tower is used for positioning

Embodiment Construction
[0029] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0030] As mentioned above, the present invention proposes a positioning scheme that can determine whether the positioning signal received by the receiving end is valid. In order to facilitate the description of the positioning scheme of the present invention, the specific positioning scenarios to which the positioning scheme of the present invention can be applied are firstly discussed below. Be explained.
[0031] For ease of understanding...

The invention discloses a positioning method, device and system. The positioning method comprises steps of: judging whether a positioning light beam received by an optical signal receiver corresponds to a reference light pulse received before the positioning light beam is received, i.e., judging whether the positioning light beam and the reference pulse are emitted by a relevant positioning light signal emission device and a reference light source respectively in the same scanning period; on the condition that the positioning light beam corresponds to the reference light pulse, positioning a to-be-positioned object based on the positioning light beam and the reference light pulse; and on the condition that the positioning light beam does not correspond to the reference light pulse, positioning the to-be-positioned object not based on the positioning light beam and the reference light pulse. Therefore, by judging the positioning light beam and the reference light pulse received by the optical signal receiver, whether the positioning light beam corresponds to the reference pulse is determined, and on the condition that it is determined that the positioning light beam corresponds to the reference pulse, the to-be-positioned object is positioned by use of the positioning light beam and the reference light pulse, so positioning accuracy can be improved.
Description
technical field [0001] The present invention relates to the field of positioning, in particular to a positioning method, device and system. Background technique [0002] As an auxiliary positioning of satellite positioning, indoor positioning technology can solve the problem that satellite signals are weak when they reach the ground and cannot penetrate buildings. Laser positioning technology is a common indoor positioning technology. The solution is to build a positioning light tower emitting laser in the positioning space, scan the positioning space with laser, design multiple optical signal receivers on the object to be positioned, and The receiving end performs arithmetic processing on the data, and directly outputs the three-dimensional position coordinate information. [0003] When the positioning space is expanded into multiple sub-positioning spaces, at least one positioning light tower is provided in each sub-positioning space. Among them, in order to enable the e...
