基于OpenVG加速的矢量地图系统设计与实现
Based on OpenVG Acceration Vector Map System Design and Implementation
摘要
Abstract
Rraster maps and vector-raster mixed data are data sources for most recent electronic maps which leads to big mem-ory occupation and less flexible for updating.A display system is presented to design an electronic map based on vector graphic tak-ing advantage of OpenVG hardware rendering acceleration.Through Qt graphical development tools to design a vector map display tool based on Linux operating system,the system achieve functions including map display and control as well as drawing,rendering optimization,performance analyzing and resolution control,etc.The experiment results show that the system gains hardware render-ing acceleration on hardware platform Freescale IMX6Q,cutting occupancy of CPU by a large margin when rendering result re-mains.关键词
