Abstract

The invention discloses a multi-band optical binary remote sensing data visualization method, and relates to the field of remote sensing satellite image data visualization. The method comprises the following steps of acquiring the data description information; calculating a display scaling; calculating the number of transverse and longitudinal pixels during the display of an effective display area; calculating the entity data to be displayed; creating a binary remote sensing data cache region, and performing visualization according to the display requirements; monitoring a screen mouse operation event; calculating a multi-band optical binary remote sensing data area corresponding to the display area after a remote sensing image is zoomed; and calculating a multi-band optical binary remote sensing data area corresponding to the display area after the remote sensing image is translated. According to the invention, the smooth real-time interactive display of the multi-band optical remote sensing image can be realized without very high computer hardware configuration.

Description

technical field [0001] The invention relates to the field of remote sensing satellite image data visualization, in particular to a multi-band optical binary remote sensing data visualization method. Background technique [0002] With the advancement of remote sensing imaging technology, the resolution of remote sensing images has gradually increased, and the amount of data has gradually increased. For example, the domestic Gaofen series satellites, Jilin-1 series satellites, and Gaojing-1 satellites have spatial resolutions up to or better than the sub-meter level, among which the spatial resolution of Gaojing-1 images can reach 0.5 meters. The amount of data reaches the level of several Gbytes, and the bit depth of independent channel data is usually greater than 8 bits, which cannot be directly displayed in the operating system like ordinary pictures. If you directly read the entire image file into the memory, use the CPU to perform bit-depth compression calculations, and...
