Dynamic frame rate acquisition method and system

The invention relates to the field of monitoring, in particular to a dynamic frame rate acquisition method and system. The method comprises the following steps: acquiring an entry address of a display picture function to obtain a first address, wherein the display picture function is used for displaying a picture drawn in the background on a current interface; presetting a first function, wherein the first function is used for calculating a frame rate, executing a function body of the display picture function and displaying the frame rate; acquiring an entry address of the first function to obtain a second address; setting a function pointer of the display picture function to point to the second address; setting a function pointer of the first function to point to the first address. By adopting the dynamic frame rate acquisition method and system, the frame rate of the current interface can be acquired in real time without modification of a source code. 本发明涉及监控领域，尤其涉及种帧率动态获取的方法及系统。本发明通过获取显示画面函数的入口地址，得到第地址；所述显
