Emerald Bay Barge 2

This is one of two barges now lying adjacent together near the southern shore of Emerald Bay State Park, Lake Tahoe. Historically, the barges were lashed to the sides of a lake steamer, and used to transport construction materials and other bulky commodities. Both barges likely sank at their moorings some time after construction of the Lake Tahoe highway in 1913. The model documents an area of 507 square meters and is composed of 2636 aligned images collected from an average distance to target of 1.93 m during a single dive on 27 July 2016. Estimated scalar error is 0.003472 m. According to photogrammetric measurements, the vessel dimensions are 9.5 m x 59.3 m. This model was created out of a collaborative project between the Indiana University Center for Underwater Science and California State Parks. Images collected by Matthew Maus and Sam Haskell, Indiana University, during the Lake Tahoe Underwater Photogrammetry Workshop in July 2016.

本数据集所呈现的是两艘目前彼此毗邻停泊于太浩湖（Lake Tahoe）翡翠湾州立公园南岸附近的驳船其中之一。历史上，该两艘驳船曾被系缚于湖上汽船的舷侧，用于运输建筑材料与其他大宗货物。据推测，两艘驳船均于1913年太浩湖公路建成后的某一时期，在停泊处沉没。该三维模型覆盖区域面积达507平方米，由2016年7月27日单次水下探测期间采集的2636张配准图像构成，图像采集时距目标的平均距离为1.93米。估算得到的标量误差为0.003472米。经摄影测量测算，该驳船尺寸为9.5米×59.3米。本模型由印第安纳大学水下科学中心与加利福尼亚州公园部门合作项目研发而成。图像由印第安纳大学的Matthew Maus与Sam Haskell于2016年7月太浩湖水下摄影测量讲习班期间采集。摄影测量工作与数据集说明文本由印第安纳大学的Matthew Maus完成。来源：Objaverse 1.0 / Sketchfab
