Embodiment Construction

[0063] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0064] Such as figure 1 As shown, a method for detecting online car-hailing taxis disclosed in this embodiment, the specific steps are as follows:

[0065] Based on the differential positioning of the GNSS reference receiver of the satellite navigation system and the combined positioning of the inertial system INS, the high-sampling and high-precision positioning of the vehicle carrier in the real environment is solved;

[0066] Using the motion model equation of the inertial navigation system INS, the northeast sky coordinate system is used as the navigation coordinate system ( system) to establish INS position, velocity, and attitude error update equations, includ...

Abstract

The invention discloses an online car-hailing log detection method, system and device and a computer readable storage medium, and the method comprises the steps: carrying out combined positioning based on satellite navigation system GNSS reference receiver differential positioning and an inertial navigation system INS, and solving a high-precision discrete point positioning result of a vehicle carrier in a real environment; by utilizing the high-precision discrete point positioning result and combining with a lane electronic map, carrying out mileage recovery of a vehicle driving track, and obtaining a reference mileage; and comparing the reference mileage with a distance counting result of an online car-hailing terminal to obtain an online car-hailing distance counting error. According to the invention, an accurate comparison reference can be provided for online car-hailing logging, so that logging detection in a real dynamic road test environment is realized; the reference mileage can be directly calculated by importing the combined positioning result file and inputting the distance counting result of the online car-hailing end, so that the distance counting error of the online car-hailing end is obtained; according to the invention, the accuracy and continuity of positioning can be ensured, and the metering efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle mileage detection, and in particular relates to a method, system, device and computer-readable storage medium for online car-hailing distance detection. Background technique [0002] With the popularization and application of the Internet and mobile smart terminals, online taxi booking (hereinafter referred to as "online taxi") has gradually become one of the important ways for the public to travel, and has become an important part of smart people's livelihood. Online car-hailing realizes billing for users by recording the driving distance and driving time of the vehicle service process. Accurate metering is an important guarantee for reasonable charging and standardized services for online car-hailing. At present, online car-hailing taxis in the market usually use mobile phone positioning services, that is, use the built-in low-cost positioning module and electronic map of the mobile phone for ta...
