Embodiment 1

[0043] A method for evaluating navigation positioning accuracy, specifically comprising the following steps:

[0044] Step 1: Install the integrated navigation device using single-axis gyroscope, inclinometer and odometer (patent application "Integrated navigation device and method using single-axis gyroscope, inclinometer and odometer", application number is 201610564309.2) in On the robot carrier, mark the reference point; set up the RTK reference station, install the RTK rover on the robot carrier, wherein: ensure that the reference point of the RTK rover coincides with the reference point of the robot carrier; the sampling rate of the RTK rover is 0.5 Seconds - 5 seconds (0.5 seconds is taken here);

[0045] Second step: start the robot carrier, record the position coordinates calculated by the integrated navigation device and the position coordinates output by the RTK mobile station while walking (see the track diagram for details figure 1 ); the integrated navigation de...

Abstract

The invention provides a method for evaluating navigation positioning accuracy, and the method comprises the following steps: 1, a combined navigation device based on a single-axis gyroscope, an inclinometer and a milemeter is installed on a robot carrier, and a reference point is marked; an RTK base station is erected, a RTK moving station is mounted on the robot carrier to ensure the reference point of the RTK moving station is coincident with the reference point of the robot carrier; and 2, the robot carrier is started, position coordinates calculated by the combined navigation device and position coordinates outputted by the RTK moving station are recorded while walking; and 3, a relative positioning accuracy algorithm and an absolute positioning accuracy algorithm are used to calculate and process the two sets of coordinate information to obtain a relative positioning accuracy value and an absolute positioning accuracy value. The method has the advantages of being simple in steps,capable of obtaining the accurate relative positioning accuracy value and absolute positioning precision value, and capable of effectively evaluating the positioning accuracy of the combined navigation device.

Description

technical field [0001] The present invention relates to the technical field of navigation and positioning, in particular, to a method for evaluating the accuracy of navigation and positioning. Background technique [0002] There are many accuracy evaluation methods for navigation and positioning in the prior art, but these methods are not applicable to the patent application "Integrated Navigation Device and Method Using Single-axis Gyroscope, Inclinometer and Odometer" (application number 201610564309.2) ,Details are as follows: [0003] For example, when testing the dynamic positioning accuracy of GPS-RTK, the RTK rover station is placed on a large disk at a fixed position, and the disk rotates around the dot, so that the trajectory of RTK positioning is a circle, and the trajectory and the distance between the dot and the RTK are RTK positioning accuracy can be obtained by comparing the circumference of the radius. However, this method is not applicable to the patent "I...
