Provided is a microsphere including a glass sphere core. The glass sphere core includes a first nuclide, a second nuclide and a diffusion region extending inwardly from an outer surface of the glass sphere core, with the second nuclide distributed in the diffusion region. The first nuclide and the second nuclide become radioactive after being activated by neutrons to produce radiations including &#x3b2;-rays or &#x3b3;-rays, or simultaneously &#x3b2;-rays and &#x3b3;-rays. A preparation method of a microsphere is also provided.

A method for true-orthoimage color correction is provided. Aerial images and digital elevation models (DEMs) are used for balancing colors in orthoimages or true-orthoimages. Seam lines between images are also smoothed. Thus, color distinction between images is rectified and orthoimage quality is greatly enhanced.

Method of orthoimage color correction using multiple aerial images

The present invention provides coefficient for a strip-based image taken by a satellite. By using the coefficient, the absolute error of the image can be made smaller than two pixels. Therefore, the accuracy of the image is high. The present invention can be applied to any pushbroom scanning satellite.
