The invention relates to the technical field of wireless electric energy transmission, and particularly discloses an electric vehicle alignment guiding method and system integrating machine vision and magnetic field induction, and the method comprises two parts: machine vision guiding and magnetic field guiding. At a long distance, the relative position of the primary coil and the secondary coil is calculated through visual processing, and after feedback is given, position information and a guide route are given; the magnetic field guide is expanded based on primary and secondary coils, small voltage excitation is given to the ground end in a short distance, the voltage change of the secondary side is detected to judge position information, and a guide route given based on a camera is corrected. According to the method, in a fixed scene, only the camera needs to be arranged, detection of the parking space and the primary coil is achieved, the mode is low in implementation cost and wide in application range, then magnetic field guiding is carried out in combination with electromagnetic induction of the primary coil and the secondary coil, and the relative position relation between the primary coil and the secondary coil can be accurately obtained.
本发明涉及无线电能传输技术领域,具体公开了一种融合机器视觉与磁场感应的电动汽车对位引导方法及系统,分为机器视觉引导与磁场引导两个部分,机器视觉引导即摄像头检测车位线,远距离时通过视觉处理计算出原副边线圈的相对位置,给予反馈后给出位置信息和引导路线;磁场引导基于原副边线圈展开,近距离时地面端给予小电压激励,检测副边的电压变化来判断位置信息,对基于摄像头给出的引导路线进行修正。本发明考虑在固定场景下,仅需设置摄像头,实现车位及原边线圈的检测,这种方式实现成本比较低,可适应的范围比较广,然后结合原副边线圈的电磁感应进行磁场引导,能较为准确地获得原副边线圈之间的相对位置关系。
