【摘要】 海滩剖面测量是获取海滩地形地貌形态最直接的方法。本文提出了一种基于激光原理的海滩剖面简易测量方法,在厦门市同安区选取了6条测线进行了实地测量,测量结果与全站仪法的对比发现,各条测线上的各个测点的测量精度均在96.7%以上,少数误差较大是因为风速较大时吹动测距仪摆动导致的。这种测量方法具有简单快速的特点,测量点距离可以任意设定,且不易产生误差累计,黑夜、大雾均可测量,但不适合于强光和风速较大的天气。更多还原

【Abstract】 The beach profile measurement is the most direct access to the beach topography.This paper presents a convenient beach profile measurement method based on laser principle.Six survey lines were selected for field measurement at Tongan in Xiamen,and the measurement results were compared with those by the total station method.It shows the measurement accuracy is more than 96.7%,and a few large errors were induced by swings of laser rangefinder in wind.This measurement method is simple and rapid,and the measuring point distance can be arbitrarily set.The accumulative errors are not produced easily.It can be used in night and fog days,but not suitable for strong light and large wind weather.更多还原
