The invention provides a method and device for estimating the moving speed of a vehicle and a monitoring system, and the method comprises the steps: sequentially obtaining a first driving image and a second driving image through an image obtaining unit, wherein the first driving image and the second driving image have a time difference; performing image analysis on the first driving image to obtain a first pixel area and a first inclination angle of a first license plate image; performing image analysis on the second driving image to obtain a second pixel area and a second inclination angle of a second license plate image; and estimating the moving speed of the vehicle according to the first pixel area, the first inclination angle, the second pixel area, the second inclination angle and the time difference. According to the technical scheme, the moving speed of the vehicle can be estimated by analyzing the first driving image and the second driving image which are sequentially acquired.
本发明提供一种车辆的移动速率的估算方法、装置和监控系统,该车辆移动速率的估算方法包含:利用图像获取单元依序获取第一行车图像与第二行车图像,其中该第一行车图像与该第二行车图像间具有时间差;对该第一行车图像进行图像分析以得到第一车牌图像的第一像素面积与第一倾角;对该第二行车图像进行图像分析以得到第二车牌图像的第二像素面积与第二倾角;根据该第一像素面积、该第一倾角、该第二像素面积、该第二倾角与该时间差估算车辆的移动速率。上述技术方案,通过对依序获取到的第一行车图像与第二行车图像进行图像分析,可以估算出车辆的移动速率。
