Problems solved by technology
[0009] The purpose of the present invention is to propose a detection method for magnetic detection accuracy, to solve the problem that in the model calculation, the existing research ignores the actual working conditions, only calculates the situation of the magnetic target in a specific direction, and one-sidedly weighs the magnetic detection method. Detection accuracy, and in the experimental detection, the existing research ignores the influence of the motion trajectory of the magnetic target on the detection accuracy. A simple selection of a motion trajectory cannot accurately detect the detection accuracy of the magnetic detection method.

The present invention proposes a detection method for magnetic detection accuracy, said detection method comprising the following steps: establishing an omnidirectional magnetic detection model, using the omnidirectional positioning error distribution diagram to calculate the influence law of the direction of a magnetic target on the magnetic detection accuracy, and providing an example for the experiment Provide the basis for the selection of the magnetic target motion trajectory in the detection; use the omnidirectional accuracy distribution curve and the omnidirectional error expectation λ 0 , to comprehensively and accurately measure the detection accuracy of the magnetic detection method; through the omnidirectional positioning error distribution map, find the motion trajectory that may be equivalent to the omnidirectional magnetic detection model, and use the total deviation rate T to select a path that can most accurately measure the magnetic detection accuracy Or multiple motion trajectories; set up an experimental platform to test the detection accuracy of the magnetic detection method. The invention can more accurately detect the detection precision of the magnetic detection method.
