摘要
通过对国内河工模型地形测量方法的回顾,系统地介绍激光技术、超声波技术、光学技术、计算机技术以及图像处理技术等先进技术在河工模型地形测量中的应用及发展,详细介绍光电反射式地形仪、电阻式地形仪、跟踪式地形仪、超声地形仪、激光扫描仪等仪器及近景摄影测量技术的优点及存在的问题,指出结合各种测量技术的优点实现河工模型地形的大范围非接触测量将是今后的研究方向。
Based on a review of the methods for topographical survey of riverbeds in physical fiver models, the application and development of advanced technologies, such as laser techniques, ultrasonic technology, optical techniques, computer techniques and image processing techniques, are systematically introduced. The advantages and existing problems of photoelectric reflecting topographic apparatuses, resistance-type topographic apparatuses, tracing topographic apparatuses, ultrasonic topographic surveying, laser scanners, and digital close-range photogrammetric techniques are described in detail. It is pointed out that widerange non-contact measurement, which combines the advantages of various measurement technologies, is a future research direction.
