Embodiment Construction

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0051] The following describes the vehicle positioning method and device according to the embodiments of the present invention with reference to the accompanying drawings.

[0052] In recent years, with the development of mobile terminals, relevant road recognition research has begun to use built-in sensors in mobile terminals, such as acceleration sensors, direction sensors, etc., to obtain the driving state and trajectory of the vehicle during driving, and to detect the lane change of the vehicle. Behavior, turning and other ac...

Abstract

The invention provides a vehicle positioning method and device. The method comprises the following steps: acquiring reference models of lanes, wherein the reference models are generated according to vertical accelerations changing along with time in directions vertical to ground of reference vehicles travelling the lanes; when a target vehicle travels, measuring the process that the vertical acceleration of the target vehicle changes along with time to obtain a test sample; and determining the target lane of the target vehicle from the lanes according to level of similarity between the test sample and the reference models of the lanes. The method can reduce the influence of environmental factors on lane recognizing accuracy and improve the lane recognizing and positioning precision and reliability, so that the problem that the recognizing accuracy is easily interfered by environmental change in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent navigation, in particular to a vehicle positioning method and device. Background technique [0002] With the development of navigation technology, users have higher and higher requirements for navigation equipment, and they begin to hope that navigation equipment can provide more accurate road reminders and other services, such as lane change reminders, fork roads, etc., so how to accurately locate the current lane of the vehicle become an urgent problem to be solved. [0003] In related technologies, road recognition is usually based on technologies such as computer vision and image processing, and image sensors are used to monitor the road in front of the vehicle in real time, and then relevant image processing algorithms are used to process the collected road condition images, and finally pass through the lane. Features such as lane markings identify the lane the vehicle is currently trave...
