Embodiment 1

[0061] The embodiment of the present invention discloses a field distribution data collection method, which is applied to a collection system including a field strength meter and a plurality of cameras, wherein the probe of the field strength meter is preset with markers, and the markers are The texture of each surface is different; the relative position of each point on the marker is known, such as figure 1 or image 3 As shown, the method includes the following steps:

[0062] Step 101. Obtain the time-related field strength signal and frequency band information of each location to be measured through the field strength meter;

[0063] Specifically, in a practical application scenario, such as figure 2 As shown, a cube with a specific texture (such as a Rubik's cube) can be fixed on the probe of the field strength meter, the relative position between the preset marker and the probe is known, and the texture (ie pattern) of each side of the cube Different, so as to facili...

Embodiment 2

[0097]In order to further illustrate the present invention, Embodiment 2 of the present invention also discloses a field distribution data collection device, which is applied to a collection system including a field strength meter and a plurality of cameras, wherein the probe of the field strength meter is preset A marker is provided, the textures of each surface of the marker are different, and the relative positions of each point on the marker are known; as Figure 8 As shown, the equipment includes:

[0098] The obtaining module 201 is used to obtain the time-related field strength signal and frequency band information of each position to be measured through the field strength meter;

[0099] The determining module 202 is configured to obtain video data obtained by a plurality of cameras shooting the field strength meter at the same time for each of the positions to be tested, and determine the position of the field strength meter at each of the positions to be tested based...

Abstract

An embodiment of the invention provides a field distribution data acquisition method and equipment. The field distribution data acquisition method and the equipment are applied to an acquisition system which comprises a field intensity indicator and a plurality of cameras. The method includes steps: acquiring time related field intensity signals and frequency band information of each to-be-detected position through the field intensity indicator; aiming at each to-be-detected position, acquiring video data obtained by shooting the field intensity indicator at a same moment through the cameras,and determining probe position information when the field intensity indicator is at each to-be-detected position on the basis of the video data; generating field distribution data aiming at four-dimensional space of each to-be-detected position according to the position information, the time related field intensity signals and the frequency band information. Images are acquired by shooting the field intensity indicator through the cameras and recognized to determine accurate positioning information of the field intensity indicator, and the positioning information is integrated with the time related field intensity signals and the frequency band information detected by the field intensity indicator to generate intact field distribution data.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a field distribution data collection method and equipment. Background technique [0002] Field strength signal measurement is the actual measurement and data processing of the distribution of useful signal field strength in space. The measurement results can be used as an important basis for network design, station site determination, and evaluation of communication quality and communication probability. [0003] There are many field strength measuring instruments on the market, most of which can only collect field signal data. In addition, there are some products with built-in GPS that can collect positioning information, but the GPS signal indoors is weak, and the positioning accuracy of GPS is generally around 5-15 meters, which has certain limitations, and at the same time collects field signal data and Products with positioning information are generally expensive. [0004] There...
