The invention relates to methods and systems for improved positioning of a vehicle. The present disclosure relates to a method performed by an object size mapping system for enabling improved positioning of a vehicle. The object size mapping system comprises at least a first reference camera adapted to be arranged on-board a reference vehicle. The object size mapping system determines a current reference position of the reference vehicle. Furthermore, the object size mapping system captures by means of the at least first reference camera, at the current reference position of the reference vehicle, a current reference image of a stationary physical reference object situated in the surroundings of the reference vehicle. The object size mapping system then determines a current reference size value of at least a portion of the stationary physical reference object, in the current reference image. Moreover, the object size mapping system stores the current reference size value to be associated with the current reference position of the reference vehicle and a mapped digital reference object (511) corresponding to the stationary physical reference object. The disclosure also relates to an object size mapping system in accordance with the foregoing, a vehicle positioning system and method performed therein, and a vehicle comprising at least a portion of the object size mapping system and / or vehicle positioning system.
Description
technical field [0001] The present invention relates to a system enabling improved vehicle positioning and a method performed therein. Background technique [0002] Improvements to autonomous vehicles have been advancing at an increasingly rapid pace in recent years. The concept of autonomous driving refers to a vehicle being driven without human interaction, at least to some extent. That is, a vehicle may have an automation level such as 0% < automation level ≤ 100%, where 0% may indicate that the vehicle is driven only by a driver, and 100% indicates that the vehicle is fully autonomous. When the level of automation is anywhere between 0% and 100%, the vehicle may perform certain actions autonomously, such as maintaining a suitable distance from the vehicle in front, while the driver may perform other actions, such as passing other vehicles when appropriate. The closer to 100%, the more actions the vehicle can perform autonomously. [0003] Autonomous vehicles, also ...
