Zusammenfassung:The invention discloses an IO (Input Output) double-buffer interactive multicore processing method for a remote sensing image. The method comprises the following steps of determining the quantity of multicore computing threads according to the quantity of CPU (Central Processing Unit) cores of a processing system; determining various data segmentation strategies according to various remote sensing image processing algorithms; starting each remote sensing image processing computing thread, starting to execute the remote sensing image processing algorithms and sending a data access request and an output request during the period; reading or writing in a data request according to the computing threads, starting a reading-writing data thread, reading image data into buffer memories R1 and R2 in order according to a predetermined reading segmentation strategy, and writing processed result data into writing buffers W2 and W1 in order; and destructing the reading-writing double-buffer and ending the reading-writing
