摘要
激光雷达是一种快速获取三维地理信息的空间测量系统,本文应用基于SOPC技术的NIOSⅡ系统解决激光雷达系统控制与数据采集的需求。本文首先介绍NIOSⅡ系统的特点,特别关注的是它基于SOPC技术的灵活性,从而选择其来实现激光雷达系统中的系统控制与数据采集子系统。从激光雷达的系统需求开始,讨论系统控制与数据采集子系统的需求,进一步的研究系统设计方案,最后完成这个子系统的实现。该子系统已经在激光雷达设备上得到了很好的应用。
Lidar is a kind of scaling system with capability of collecting 3D geographic information fleetly. This paper applies NIOS Ⅱ to fulfill the requirement of system control and data accessing in lidar. This paper presents characteristic of Nios Ⅱ system firstly, especially emphasizing its flexibility basing on SOPC. Accordingly, we choose Nios Ⅱ to implement system control and data accessing subsystem in lidar. From requirement of lidar, the paper discusses requirement of system control and data accessing subsystem, then system design, and accomplishes the subsystem. The subsystem has applied in lidar system and work very well.
