Abstract

The invention relates to a panoramic vision-based relative pose resolving method for wireless charging alignment and relates to the technical field of electric vehicle wireless charging alignment. Themethod comprises steps of obtaining a parking space visual image, and dividing an ROI image region according to the obtained parking space visual image; preprocessing the image area according to thedivided ROI image area, and filtering noise; segmenting and reserving a parking space area according to the preprocessed interested image area, and performing mark line detection on the parking spacearea; according to the detected parking space area marking lines, transformation processing being carried out, a parking area being positioned, and corner point information being obtained, and solvingthe relative pose of the vehicle according to the angular point information, and determining the relative pose of the vehicle. The method provided by the invention is based on panoramic vision, operability of a driver to a driving system can be improved, the driving risk caused by a blind area of the driver is avoided, and the potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle wireless charging alignment, and relates to a relative pose calculation method for wireless charging alignment based on panoramic vision. Background technique [0002] In order to promote the development of the new energy automobile industry, combine the leadership of technological innovation with the cultivation of strategic emerging industries. The rapid and vigorous development of the electric vehicle industry has achieved world-renowned achievements and has become an important force leading the transformation of the world's automobile industry. However, due to the limited battery capacity of electric vehicles, and the current charging facilities are not yet complete, the charging problem of the magnetic coupling mechanism hampers the development prospects of the field of electric vehicles. The difficulty that needs to be overcome in the field of wireless charging is how to accurately ...
