Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] like figure 1As shown, the indoor positioning system of the embodiment of the present invention includes a controller 1, a driving device 2, a rotating mechanism 3 connected in sequence, and a first laser range finder 41 and a second laser range finder 42 respectively connected to the controller 1 ; The first laser range finder 41 and the second laser range finder 42 are fixedly mounted on the rotating mechanism 3, and the light emitted by the first laser range finder 41 is perpendicular to the light emitted by the second laser range finder 42 .

[0045] The indoor positioning system of this embodiment is a mobile device, or called a mobile robot. The first and second two laser range finders, which are 90° to each other, are installed on the indoor positioning system to measure the coordinates of the mobile device in two-dimensional spa...

Abstract

The invention provides an indoor positioning system, which comprises a controller, a drive device, a rotating mechanism, a first laser range finder and a second laser range finder, wherein the controller, the drive device and the rotating mechanism are sequentially connected; the first laser range finder and the second laser range finder are respectively connected with the controller, and are fixedly arranged on the rotating mechanism; and light emitted by the first laser range finder is vertical to light emitted by the second laser range finder. The invention also provides an indoor positioning method. Due to the adoption of the technical scheme of the invention, the two vertical laser range finders can be utilized to realize positioning, the positioning accuracy is high, in addition, a direction of the light emitted by each laser range finder can be calibrated by utilizing a distance relationship between the two laser range finders and a reference edge, the calibration on the positioning system is realized by utilizing a simple structure, and the conception is novel.

Description

technical field [0001] The invention relates to a non-contact positioning device and a positioning method. Background technique [0002] With the continuous maturity and development of computer technology, sensor technology, servo motor technology, control theory and other technologies, more and more workers are using equipment that can achieve precise positioning in factories, workshops and other environments and complete mobile tasks. The requirements are met, and the maturity and development of technology also make it possible to develop such equipment. However, the current wireless indoor positioning system has the problems of high cost and low positioning accuracy. The current popular wireless indoor positioning systems include: ZigBee, UWB (ultra-wideband), RFID radio frequency identification positioning, ultrasonic positioning, GPS, geomagnetic positioning, etc. , the positioning accuracy of these positioning methods ranges from more than ten centimeters to several m...
