Instrument display method based on image interception

The invention discloses an instrument display method based on image interception. The instrument display efficiency under an unreal engine 5 is improved. According to the method, the instrument is independently developed outside the program of the unreal engine 5, and the developed instrument forms an independent display window and is provided with a window handle of the instrument; an independent thread is started in a program of the unreal engine 5, screenshot and cache functions are set in the independent thread and used for circularly intercepting images from an instrument program window, storing the images in a bitmap format and storing the images in a picture cache of the unreal engine 5, and a picture display interface is created in the unreal engine 5 to display the instrument on a screen; and for a plurality of instruments, displaying the instruments according to the intercepted images in sequence. According to the method, an interception type display instrument is adopted, so that the independence a
