Abstract: A detection method and system are used for a moving target based on multiple sensors on the same platform. N mutually independent image sensors arranged on a monolithic planar array sensor compose an image sensor group, which has a layout where n image sensors are arranged equidistantly on the same line in a travelling direction of a satellite. The method includes respectively collecting image data by the multiple sensors, performing on-board pre-processing to the image data collected by each image sensor, acquiring an image from the received pre-processed image data, and performing operation to the image from different image sensors, to recognize the moving target. The system includes sequentially connected sensor groups, an image data pre-processing device and a wireless transmitting device, a wireless receiving device wirelessly connected with the wireless transmitting device, and a moving target recognition device connected with the wireless receiving device.

Abstract: The present invention discloses a method and device for storing image data, the method includes: receiving image data to-be-stored; extracting basic information of the image data and generating a header file; partitioning the image data by a preset block size according to the basic information of the image data, and generating a data file; and storing the header file and the data file and generating a storage file. In the present invention, image data are stored as double files, so as to add basic information of an image into the image, and in storing a massive-data image, the image is partitioned by a preset size prior to sequential storage, so that when the image is displayed, only one or several sub-blocks of the image are extracted and displayed, allowing quick display of the image with massive data, improving the efficiency of image display.
