Self-adaptive acquisition and storage method for high-speed video data

The invention discloses a self-adaptive acquisition and storage method for high-speed video data, which comprises a self-adaptive model of an acquisition frame rate and a windowing size of an acquisition image according to an acquisition frame frequency of an acquisition device under the condition of fixed acquisition time and fixed acquisition data flow aiming at the actual application requirement of high-speed video data acquisition. Calculating the windowing size of the collected image, and executing the collection operation; on the premise that the total buffer area is smaller than 50% of the memory capacity of the processor, the windowing size of an acquired image is used as the capacity of a single memory buffer area, the number of the memory buffer areas is calculated, and then high-speed video data are sequentially read and written into the memory buffer areas one by one in a circulating read-write mode; establishing a self-adaptive model of the transmission speed and the storage mode of the hard disk
