I am the overseas product consultant for BLV Tech. I like this job, which can revolutionize the traditional surveying field with cutting-edge technology, to make aerial surveying more accurate, efficient, convenient, and affordable. I love our products, good tools are essential things, release manpower, and working smarter is better than working harder.The requirements for accurate 3D models are ever-increasing. For example, within urban mapping, 3D models are used for space management, energy requirement analysis, traffic and pollution monitoring, and disaster management. In surveying, an accurate 3D model can identify potential problems early in a project’s timeline.Some more benefits of 5-lens oblique photography include: Images captured with an oblique camera reveal details that otherwise may have been obstructed in the vertical view by foliage or tall buildings.Oblique photography makes it easier to accurately determine the elevation of features when compared with vertical aerial photographsAs opposed to an orthographic setup, where the central camera looks directly down, the oblique system captures far more of the relative height data ahead of it. This also negates any lens distortion in all directions around the focal point, which the orthographic method could often suffer from.Using 5 lens camera, the position, and relative height information gathered from each dataset can be compared, contrasted, and then amalgamated to give the relative height information between elements in the target area, producing a map of both position and height data, which can be rendered as a 3D map of the area surveyed.Want to become our dealer in your country or buy products, contact me for more details. vanson.choo@blvtech.com, Mb/Whatsapp/Wechat +86 13798596007
