Статья посвящена вопросам разработки методики картирования дна неглубоких водоемов методом лазерной батиметрии. Сформулирована и решена задача разработки способа картирования рельефа дна неглубоководных водоемов. В качестве излучателя используется лазер, установленный на борту летательного аппарата. На основе геометрического представления хода оптических лучей в лазерной батиметрии и анализа известных результатов измерений предложена ступенчатая модель дна водоема, высота и ширина ступенек которой изменяются в широких пределах. На основе известного метода картирования дна неглубоководного водоема с одной точки предложен способ двухточечного измерения с применением ступенчатой модели дна. Проведенные модельные исследования показали, что погрешность измерения предложенного способа находится в пределах ±4.5%.

The article is devoted to the development of methods for mapping the bottom of shallow water bodies by laser bathymetry. The problem of developing a method for mapping the topography of the bottom of shallow water bodies has been formulated and solved. The emitter is a laser mounted on board the aircraft. Based on the geometric representation of the path of optical beams in laser bathymetry and the analysis of known measurement results, a stepped model of the bottom of a reservoir is proposed, the height and width of the steps of which vary over a wide range. Based on the well-known method of mapping the bottom of a shallow water body from one point, a two-point measurement method using a stepped bottom model is proposed. The conducted modeling studies have shown that the measurement error of the proposed method is within ±4.5%.
