Embodiment Construction

[0029] The application scenario of this embodiment is: KIAK5 and HTCDesireG7, HondaAccord and HuaweiHonor3C, VolvoS60L and ZTEU809, MazdaAtenza and HTCEVO3D, AudiA4L and SAMSUNGN Nexus4 are selected as experimental vehicles and mobile phones, wherein: each vehicle is equipped with a driving recorder, so that the shooting content as the calibrated real data. The collected data comes from the natural driving of 5 drivers over a period of 5 months.

[0030] In this embodiment, a smart terminal with a built-in sensor (acceleration sensor and GPS sensor) is used for data collection, the jitter noise in the data is removed through a low-pass filter, and then the coordinate system of the mobile phone is aligned with the coordinate system of the vehicle, and according to the data detected by the smart terminal Acceleration information judges the current lane-changing behavior of the vehicle and the number of lanes crossed when changing lanes, such as figure 1 shown.

Abstract

The invention relates to an intelligent terminal sensing-based highway vehicle lane identification method and system. The method includes the following steps that: a built-in sensor in an intelligent terminal is utilized to acquire data; jitter noise in the data are removed through a low-pass filter; the coordinate system of the intelligent terminal is aligned with the coordinate system of a vehicle; and the lane changing behavior of the current vehicle and the number of lane dividing lines which are crossed by the vehicle in lane changing can be judged according to acceleration information detected by the intelligent terminal. According to the intelligent terminal sensing-based highway vehicle lane identification method and system of the invention, a lane where a vehicle running on a highway is located can be judged through sensing different types of lane changing behaviors.

Description

technical field [0001] The present invention relates to a technology in the field of unmanned driving, in particular to a method and system for identifying highway vehicle lanes based on intelligent terminal sensing. Background technique [0002] With the maturity and complexity of the traffic network, the vehicle positioning system has become more important in driving. In many applications (such as route navigation, vehicle safety systems, and Internet of Vehicles), the accuracy of positioning largely determines the quality of service users can get. [0003] Therefore, the road-level positioning widely used today will eventually be replaced by the lane-level positioning. From a safety point of view, if the lane in which the vehicle is located can be sensed in real time, dangerous lane-changing behaviors can be reminded in time. From a convenience point of view, critical intersections will not be missed if the driver is pre-cued to prepare in the correct lane before enteri...
