Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1, a method for displaying a situation of a scene object according to an embodiment of the present invention includes:
step S101: first coordinate information of a mobile device located in a current area is acquired.
Specifically, taking the area to be measured located in the airport as an example, a plurality of receiving stations and RTK GNSS reference stations are arranged at the peripheral position of the area to be measured according to the measurement requirement. The RTK GNSS mobile station is fixed on the mobile equipment, and the mobile equipment can be vehicle-mounted equipment, so that the vehicle-mounted equipment moves at a low speed according to a designed route, and a driving route is ensured to completely cover all runways, taxiways, contact roads, parking aprons and parking stalls, namely, a region to be detected. In the moving process of the mobile equipment, the RTK GNSS mobile station and the fixed RTK GNSS base station work in a matched mode, the RTK GNSS mobile station can acquire position information of the RTK GNSS mobile station in real time and send the position information to the processor, and the position information of the RTK GNSS mobile station is first coordinate information of the mobile equipment in the current area. The RTK GNSS rover station and the fixed RTK GNSS reference station work together to acquire position information of the RTK GNSS rover station in the prior art, and details are not repeated herein. In order to visually display a situation map of an area to be detected, a static map corresponding to the actual layout of an airport is drawn before data are collected, the static map comprises elements such as a runway, a taxiway, a contact way, an air park and an air station, the position of each receiving station is marked, then the static map is divided in a grid matrix mode, the area to be detected in the static map is composed of a series of grids, the actual area to be detected is correspondingly divided into a plurality of cells, the size of each cell of the actual area to be detected is 5m x 5m according to the proportion of the static map, and the current area is any cell. The area moved by the mobile device covers each cell, and when the mobile device is in each cell, the RTK GNSS mobile station collects the first coordinate information at least once and sends the first coordinate information to the processor.
Step S102: second coordinate information is calculated based on the distance of each receiving station from a reference beacon located on the mobile device.
Specifically, a reference beacon is fixed on the mobile device, the reference beacon sends signals to each receiving station, and the receiving stations receive the signals and feed the signals back to the processor. Because the distances between the receiving stations and the reference beacon are different, the time for receiving the signals by the receiving stations is different after the reference beacon sends the signals. The processor can calculate the distance between each receiving station and the reference beacon according to the time of the feedback signal of each receiving station, and can calculate the coordinate information of the reference beacon, namely the second coordinate information according to the distance between each receiving station and the reference beacon. The processor calculates the coordinate information of the reference beacon according to the distance between each receiving station and the reference beacon, which is the prior art and is not described herein again. The processor calculates second coordinate information at least once when the mobile device moves into each cell.
Step S103: and calculating the positioning precision of the current area according to the first coordinate information and the second coordinate information. The method comprises the following steps:
step S1031: and if the acquisition time of the first coordinate information is the same as the acquisition time of the second coordinate information, calculating the error distance between the first coordinate information and the second coordinate information.
In particular, it is assumed that the processor calculates and outputs a trace point PM based on the feedback signals of the receiving stationsiThe coordinate is (PMX)i，PMYi) I.e. second coordinate information, recording the moment of time as PMTi. Correspondingly, the processor is used for processing signals sent by the RTK GNSS mobile station at the PMTiOutputs two adjacent point traces PD in the similar time segmentiAnd PDi+1Having coordinates of (PDX) respectivelyi，PDYi) And (PDX)i+1，PDYi+1) I.e. first coordinate information, recording time being PDT, respectivelyiAnd PDTi+1。
Within the same cell, if time PMTiEqual to PDTiThen the trace point PM can be directly calculatediAnd trace point PDiThe error distance L betweeniI.e. Li*Li＝(PMXi-PDXi)*(PMXi-PDXi)+(PMYi-PDYi)*(PMXi-PDYi) Namely, the positioning accuracy of the cell is obtained.
Step S1032: and if the acquisition time of the second coordinate information is between the acquisition times of the two pieces of first coordinate information, calculating third coordinate information between the two pieces of first coordinate information by an interpolation algorithm.
Specifically, within the same cell, if time PMTiInterval PDTiAnd PDTi+1Meanwhile, the new trace point PD 'can be calculated through an interpolation method'iCoordinate (PDX'i，PDY’i) I.e. third coordinate information, wherein PDX'i＝PDXi+(PDXi+1-PDXi)*(PMTi-PDTi)/(PDTi+1-PDTi) From PDY to PDY'i＝PDYi+(PDYi+1-PDYi)*(PMTi-PDTi)/(PDTi+1-PDTi)。
Step S1033: and calculating the error distance of the third coordinate information and the second coordinate information.
Specifically, calculating an error distance L ' between the point trace PMi and the new point trace PD ' i 'iI.e. L'i*L’i＝(PMXi-PDX’i)*(PMXi-PDX’i)+(PMYi-PDY’i)*(PMXi-PDY’i) Namely, the positioning accuracy of the cell is obtained.
In the same cell, if the second coordinate information output by the processor based on the feedback signal of each receiving station is a plurality of traces and the first coordinate information is also a plurality of traces, the error distances of the first coordinate information and the second coordinate information at the same or similar time are calculated according to the above method, and finally, the average value of the error distances is calculated as the positioning accuracy of the cell.
Step S104: and outputting a scene target situation map of each receiving station in the current working state according to the positioning accuracy of each region, wherein the working state of each receiving station represents the number of the opened receiving stations.
Specifically, when all receiving stations are in the on state, the processor calculates the positioning accuracy of each cell according to the received data and step S103, marks different colors for the cells with different positioning accuracies according to the numerical value of the positioning accuracy, and makes the different colors represent the different positioning accuracies, thereby obtaining the scene target situation map in which all the receiving stations are in the on state. For example: the specific meanings for defining different colors of the cells are as follows:
grayscale 1 (light): the positioning precision reaches below 7.5 meters;
grayscale 2 (medium): the positioning precision reaches 7.5 to 12 meters;
grayscale 3 (depth): the positioning precision reaches 12 to 20 meters;
grayscale 4 (heavy): the positioning precision reaches more than 20 meters.
The state of turning off one or more receiving stations is equivalent to not collecting data of corresponding receiving stations, in order to reduce the test time, the positioning precision of each cell is recalculated by adopting a method of removing all test data of corresponding receiving stations, namely the positioning precision of each cell when the corresponding receiving stations are turned off, and different colors can be marked for the cells with different positioning precisions according to the positioning precision of each cell. For example, assuming that ten receiving stations are provided, the processor may output scene target situation maps in all on states of the ten receiving stations by collecting coordinate information in all on states of the ten receiving stations, and if one or more of the scene target situation maps in all on states of the ten receiving stations is to be output, remove feedback data of the corresponding one or more receiving stations to recalculate the positioning accuracy of each cell, and output the corresponding scene target situation map. In another embodiment of the present invention, the corresponding positioning accuracy may also be tested in each working state of the receiving station, and the scene target situation map may be output. For example, assuming that there are ten receiving stations in total, if a target situation map in a state where one or more of the receiving stations are closed is to be output, the positioning accuracy of each cell is tested in each state, and a scene target situation map in each state is output. The scene target situation map under different working states is drawn, the influence of each receiver on the positioning precision of each cell can be visually displayed, and the decision and coordination arrangement work of a user are facilitated.
