The invention relates to a traffic signal timing scheme optimization method and system based on aerial view images, and the method comprises the steps: obtaining road aerial view image data in a plurality of traffic time periods, carrying out the image processing of the road aerial view image data, obtaining target image data corresponding to each traffic time period, and carrying out the optimization of the traffic signal timing scheme based on the target image data. And performing traffic parameter identification processing on the target image data to obtain a traffic saturation parameter corresponding to the current traffic time period, and performing scheme optimization evaluation processing on a traffic signal timing scheme running at the current intersection according to the traffic saturation parameter to generate a traffic signal timing optimization scheme matched with the current traffic flow. The method and the device have the effect of improving the timeliness of adjusting the traffic signal timing scheme.
