摘要

研究了利用消费级水下机器人和无人机对鲱鱼产卵场面积进行核算的方法。由于其相对较低的成本,易于部署和应用,这些设备很有希望使用。实验程序于5月11日至6月9日在鄂霍次克海北部的克鲁格拉亚湾和通古斯卡亚湾进行。在水下机器人的帮助下,应采用短点潜水和短断面的方式对产卵场进行调查。底部的一系列截图,记录在移动设备上,可以自动进行地理参考。这项工作还应在移动地理信息系统(GIS)中记录轨道、车站坐标和其他属性数据。产卵地上空的无人飞行必须以自动线性和多边形任务或手动模式进行。正射影像制作的最佳高度为150m,图像正向重叠不小于80%,侧面重叠不小于50%(如果底部能见度和调查条件非常好,则不小于20%)。在恶劣的调查条件下,首选在50米高度的产卵场上空进行之字形飞行,拍摄一系列无交集的照片,不制作正射影像。将水下和无人调查的资料集成到桌面GIS中,可以提供高精度和高效率的估计产卵区域,最大程度地记录和获得的资料的可验证性。

Development of instrumental methods for accounting the spawning grounds area of herring in the Sea of Okhotsk
Methods for accounting of herring spawning grounds area using consumer grade underwater robots and UAVs were worked out. Such devices are promising for use due to their relatively low cost, ease of deployment and application. Experimental procedures were carried out from May 11 to June 9 in the Kruglaya and Tungusskaya bays (the northern part of the Okhotsk Sea) during the period of herring spawning. With the help of underwater robots, spawning grounds should be surveyed by short point diving and short transects. Series of screenshots of bottom, recorded on a mobile device, could be georeferenced automatically. The work should be accompanied by the recording of tracks, station coordinates and other attribute data in a mobile geographic information system (GIS). Unmanned flights over spawning grounds must be carried out in the mode of automatic linear and polygon missions or manually. For the orthophotos production, the optimal height is 150 m with a forward overlap of images no less than 80% and a side overlap no less than 50% (no less than 20% in case of very good bottom visibility and survey conditions). During harsh survey conditions, zigzag flights over spawning grounds at a height of 50 m are preferred with shooting a series of photographs without intersection and no orthophotos production. The materials of underwater and unmanned surveys, integrated into the desktop GIS, provide high accuracy and efficiency in estimating the area of spawning grounds, the maximum degree of documentation and verifiability of the obtained materials.
