一种基于面向对象辅以DSM的建筑物提取方法
Global Geology（2018）
Abstract
基于面向对象技术并辅以DSN的方法来快速提取建筑物信息, 从LiDAR点云数据生成的DSM中提取到坡度信息, 并根据对象的高度信息来提取到建筑物的大致轮廓, 然后分割建筑物轮廓外的对象, 依据已分建筑物对象的空间信息、形状信息及光谱信息来优化建筑物轮廓.实验结果表明, 提取到的对象的正确率为97. 9％, 完整率为96. 4％.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
