The invention discloses a holographic intersection scene information intelligent calibration mapping method, device and system, and the method comprises the steps: obtaining an image of a target intersection shot by a camera carried by an unmanned plane at a specified height, and extracting a traffic indication line from the shot image; carrying out binarization processing on the extracted traffic indication lines to obtain a pixel point position set; each pixel point is correspondingly mapped to an actual road according to a mapping model to obtain an actual position point set, and according to the mapping model, the ratio of the corrected pixel point position coordinates to the corresponding actual position point coordinates is equal to the ratio of the corrected camera focal length to the unmanned aerial vehicle shooting height; the corrected position coordinates of the pixel points are obtained by correcting horizontal and vertical coordinates of the pixel points by using a first correction amount and a second correction amount respectively, and the corrected focal length of the camera is obtained by correcting the focal length of the camera by using a third correction amount. According to the invention, rapid and accurate mapping calibration can be carried out on the road scene information, and digitization and holography of the road information are realized.

    本发明公开一种全息路口场景信息智能标定映射方法、装置及系统,该方法步骤包括:获取利用无人机搭载相机在指定高度拍摄的目标路口的图像,并从拍摄的图像中提取出交通指示线;将提取出的交通指示线进行二值化处理得到像素点位置集合;将各像素点分别按照映射模型对应映射到实际道路得到实际位置点集合,映射模型为修正后像素点位置坐标与对应的实际位置点坐标之间的比值等于修正后相机的焦距与无人机拍摄高度之间的比值,修正后像素点位置坐标为分别使用第一、第二修正量对像素点横纵坐标进行修正得到,修正后相机的焦距为使用第三修正量对相机的焦距进行修正得到。本发明能够将道路场景信息进行快速、精确的映射标定,实现道路信息数字化、全息化。
