The invention relates to the technical field of intelligent parking, and discloses an intelligent parking lot vacancy navigation method based on coordinate system positioning, and the method comprises the steps: obtaining an initial image of a parking lot shot by an unmanned aerial vehicle at the current time; performing preprocessing, cumulative probability Hough transform and horizontal parking line extraction on the initial image to obtain line segment coordinates of the horizontal parking line; calculating line segment coordinates of the horizontal parking line to obtain parking space coordinates of each parking space in the initial image; according to the parking space coordinates, idle parking spaces in the initial image are extracted, and the idle parking spaces are displayed to the user; and determining a target parking space according to an instruction of the user, and planning a path from the current position of the user to the target parking space according to the position of the target parking space. According to the method provided by the invention, the initial image, shot by the unmanned aerial vehicle, of the parking lot is analyzed, the coordinates and the corresponding positions of the idle parking spaces are quickly found, the target parking space is determined according to the instruction of the user, the path is planned, and the time of a driver is greatly saved.

    本发明涉及智能停车技术领域,公开了一种基于坐标系定位的智慧停车场空位导航方法,包括:获取无人机在当前时间拍摄的停车场的初始图像;对初始图像进行预处理、累计概率霍夫变换、水平停车线提取,得到水平停车线的线段坐标;对水平停车线的线段坐标进行计算,得到初始图像中每个停车位的车位坐标;根据车位坐标提取初始图像中的空闲车位,并将空闲车位展示给用户;根据用户的指令确定目标车位,并根据目标车位的位置规划用户当前位置到目标车位的路径。本发明提供的方法,通过对无人机拍摄的停车场的初始图像进行分析,快速找到空闲车位的坐标及其对应的位置,并依据用户的指令确定目标车位并规划路径,大大节省了驾驶员的时间。
