بررسی اطلاعات Raster و Vector در ساخت تصاویر کارتوگرافی دیجیتال
امروزه با پیشرفت و توسعه تکنولوژی کامپیوتر تعداد زیادی از شرکت ها و سازمان ها که مسئولیت تهیه نقشه را به عهده دارند جهت دستیابی به نقشه های رقومی اقدام به تغییر سیستم دستی (کارتوگرافی دستی) به سیستم کامپیوتری (کارتوگرافی دیجیتال) کرده اند. حال به کمک و مساعدت کامپیوتر تمام مراحل کارتوگرافی دستی به صورت کامپیوتری انجام می گیرد. که باعث تسریع در عملیات کارتوگرافی و کیفیت برتر در مراحل ...
متن کاملRaster-to-Vector: Revisiting Floorplan Transformation Supplementary material
Figures 1, 2, 3, and 4 show more experimental results on randomly sampled floorplan images in our dataset, demonstrating their challenges and varying styles. Figures 5 and 6 show our results on other image sources, in particular, Rent3D dataset [2] and Google Image Search, respectively. Fig. 7 shows some typical failure cases. Lastly, the main paper has provided quantitative evaluations. We her...
متن کاملA Raster-to-Vector Conversion Concept Based on Industrial Requirements
A raster-to-vector (r-t-v) conversion system that is to be of general interest to the industry must meet certain requirements. With IGES as the starting point, covering the CAD area, I discuss a number of such needs. A strategy for the design of a r-t-v system that matches the requirements listed is then proposed. I find it necessary to leave the pure skeleton based approach, but use skeletonal...
متن کاملExtracting Road Vector Data from Raster Maps
Raster maps are an important source of road information. Because of the overlapping map features (e.g., roads and text labels) and the varying image quality, extracting road vector data from raster maps usually requires significant user input to achieve accurate results. In this paper, we present an accurate road vectorization technique that minimizes user input by combining our previous work o...
متن کاملA Vector-like Architecture for Raster Graphics
Raster graphics, while good at achieving realistic and cost-effective image generation, lacks useful (e.g. high-level) and fast (e.g. almost real-time) interac tion facilities. One may try to speed up the entire classical image generation pipeline using much processing power but this would clearly lessen the advan tages of raster workstations as popular, relatively inexpensive devices. This p...
