Problems solved by technology

[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

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

The embodiment of the present invention proposes a field distribution data collection method and equipment, which are applied to a collection system including a field strength meter and multiple cameras; Strong signal and frequency band information; for each of the positions to be tested, obtain video data obtained by multiple cameras shooting the field strength meter at the same time, and determine the field strength meter at each of the positions to be tested based on the video data The position is the position information of the probe; the position information, and the time-related field strength signal and frequency band information are combined to generate field distribution data for the four-dimensional space where each position to be measured is located. The field strength meter is captured by the camera to obtain pictures, and the image is identified to determine the accurate positioning information of the field strength meter, and it is integrated with the time-related field strength signal and frequency band information detected by the field strength meter to generate a complete field strength 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...
