The invention discloses a roadside parking space size estimation method and system, and relates to the technical field of image processing. The method comprises the following steps: acquiring image parking coordinates, real vehicle length and width information of a parked vehicle and vehicle chassis coordinates; real length and width information of the vehicle is converted into the aerial view in an equal proportion mode, and vehicle coordinates of the aerial view are obtained; calculating a projection transformation matrix of the aerial view vehicle coordinates and the vehicle chassis coordinates; transforming the image berth coordinates according to the projection transformation matrix to obtain aerial view berth coordinates; calculating a proportional relation between the aerial view parking space coordinates and aerial view vehicle coordinates; and according to the proportional relation and the real length and width information of the vehicle, calculating to obtain parking space length and width information. Through the roadside berth size estimation method provided by the invention, the problem of low measurement efficiency caused by manual berth size measurement is solved, manpower and material resources are saved, and the berth size measurement efficiency is improved.

    本发明公开一种路侧泊位尺寸估计方法以及系统,涉及图像处理技术领域。方法包括:获取图像泊位坐标、停泊车辆的车辆真实长宽信息与车辆底盘坐标;将车辆真实长宽信息等比例变换至鸟瞰图中,获得鸟瞰图车辆坐标;计算鸟瞰图车辆坐标与车辆底盘坐标的投影变换矩阵;根据投影变换矩阵对图像泊位坐标进行变换,获得鸟瞰图泊位坐标;计算鸟瞰图泊位坐标与鸟瞰图车辆坐标的比例关系;根据比例关系与车辆真实长宽信息,计算获得泊位长宽信息。通过本发明提供的路侧泊位尺寸估计方法,解决了人工进行泊位尺寸测量导致的测量效率低的问题,且节约了人力物力,提高了泊位尺寸测量效率。
