Embodiment Construction

[0038] The present invention will be clearly and completely described below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are part of, rather than all of, the embodiments of the present invention.

[0039] It should be understood that although the technical terms "first", "second", etc. are used here to describe the encoders, these encoders should not be limited by these terms, and these terms are used only for convenience to describe each encoder. Make a distinction. For example, a first rotary encoder could be referred to as a second rotary encoder, and a second rotary encoder could also be referred to as a first rotary encoder without departing from example embodiments.

[0040] refer to figure 1 , according to an aspect of this embodiment, there is provided a movement trace recording device 100, including a first rotary encoder 101 and a second rotary encoder 102, wherein the first rotary encoder 101 is configur...

Abstract

The invention relates to a moving track recording device comprising a first rotary encoder and a second rotary encoder. The first rotary encoder is configured to record a moving distance of the device; and the second rotary encoder is configured to record the moving direction of the device. The moving track recording device has advantages of simple structure, relatively low equipment cost and manual operation cost, and high working stability. The efficiency of indoor two-dimensional positioning is improved and thus the efficiency of the indoor three-dimensional modeling technology is enhanced.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a movement track recording device. Background technique [0002] Indoor positioning technology has been developed for many years. The current technologies include: Wi-Fi positioning, Bluetooth positioning, RFID positioning, UWB (ultra-wideband) positioning, infrared technology, ultrasonic, etc. The positioning accuracy of each technology is between centimeters and Between meters, the difference in positioning accuracy mainly depends on the environment in which each technology is used. What these technologies have in common is the need for auxiliary equipment (such as: transmitting base stations) to achieve positioning. Obviously, there are certain defects or limitations: the base station equipment increases the equipment cost and operation cost (the base station needs to be installed and debugged in advance), and positioning cannot be realized outside the range of the...
