The stereo model based epipolar line images is free from vertical parallax, which makes digital photogrammetry have a rapid development.

基于核线影像的立体模型的使用，使数字摄影测量的发展产生了一个重大的飞跃。

The existing image matching methods work well in open areas with relatively smooth terrain. However, they still meet many problems in the case of larger scale images of nature, especially in the dense city centers, forestry areas and the textureless regions such as water bodies. The reliability of image matching is still a big issue in these cases. For example, the corners of buildings and some object boundary points sometimes cannot be matched successfully, and there are many blunders in the automatically derived digital surface models that need to be manually removed, which leads to the decrease of the automaticity in digital photogrammetry.

现有大多数立体影像匹配方法对于地形平滑的开阔地带具有较高的可靠性，然而，面对从千变万化的自然界所摄取的影像，现有的匹配方法仍然存在许多问题，尤其是在植被茂密、建筑物密集和水域等区域，影像匹配的可靠性还不高，一些建筑物的角点和地物的主要边界点还不能正确地匹配出来，自动生成的数字表面模型中存在着许多异常值，需要进行大量的人工编辑处理，这在很大程度上制约了数字摄影测量自动化水平的提高。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
