摘　　要：相对低分辨力岩心图像,高分辨力岩心图像由于像素点较多,数据量较大,在传输、处理和显示过程中都将占用很大的内存开销,传统的处理方式无法实现高分辨力岩心图像的浏览显示。针对此问题,提出一种基于瓦片金字塔模型的瓦片图像分割技术,将原始高分辨力岩心图像转换为以瓦片结构存储的具有多个分辨力层的标签图像文件格式(TIFF)图像,利用分块传输和分块加载来实现高分辨力岩心图像在浏览器端的浏览显示。A huge amount of memory overhead would be occupied when the high-resolution core images are transferred, disposed and displayed compared to the low-resolution core images. The traditional solutions could not display a high-resolution core image online. A tiled image segmentation method based on tiled pyramid model is proposed to solve the problem. The original high-resolution images are firstly converted to Tagged Image File Format（TIFF） images with multiple resolutions, and then browsed and displayed by block transmission and sub-block loading in client browser.
