Image Relaxation Matching Based on Feature Points for DSM Generation

In photogrammetry and remote sensing, image matching is a basic and crucial process for automatic DEM generation. In this paper we presented a image relaxation matching method based on feature points. This method can be considered as an extention of regular grid point based matching. It avoids the shortcome of grid point based matching. For example, with this method, we can avoid low or even no texture area where errors frequently appear in cross correlaton matching. In the mean while, it makes full use of some mature techniques such as probability relaxation, image pyramid and the like which have already been successfully used in grid point matching process. Application of the technique to DEM generaton in different regions proved that it is more reasonable and reliable.

信息综合应用能力提高在高职计算机基础课程中的实践探索

目前,高职的计算机基础课程主要逐个讲授一些基础软件的操作应用,遇到实际问题,学生计算机的综合运用能力不高。本文着重探索将投资理财、生活收支分析等生活中的公共实例引入课堂,利用概率分布数字特征原理,教授学生针对性地进行信息收集——处理——分析的思维方法,综合利用所学的多种计算机手段解决实际问题的能力,确实提高学生的信息素养。
