The invention discloses a surveying and mapping instrument for natural resource management and a use method, and relates to the technical field of natural resource surveying and mapping, a processing module controls an unmanned aerial vehicle to fly at a constant speed according to a set air route and set a time interval t, the processing module controls an aerial camera to shoot a first group of images, then the time interval 0.5 t is set, and a second group of images are obtained; an aerial camera is used for shooting an image, then a time interval t is set, the aerial camera shoots a second group of images, the first two images in the first group of images are overlapped, pixel value processing is carried out on the overlapped area, image splicing is completed, and image comparison analysis is carried out on the spliced position of the spliced images and the second group of images. And judging whether the spliced image is qualified or not, repeating the steps until an overall large-scene image is obtained, and completing area surveying and mapping on the forest resources in the natural resources. According to the surveying instrument for natural resource management and the use method, the image splicing effect is good, and forest resource surveying and mapping are more accurate.
本发明公开了一种自然资源管理用测绘仪及使用方法,涉及自然资源测绘技术领域,本发明中处理模块控制无人机按照设定航线匀速飞行,设定时间间隔t,处理模块控制航拍摄像头拍摄出第一组图像,然后设定时间间隔0.5t,使用航拍摄像头拍摄一副图像,然后设定时间间隔t,航拍摄像头拍摄出第二组图像,将第一组图像中前两张图像进行重合,在对重合区域进行像素值处理,完成图像拼接,将拼接后的图像将拼接处与第二组图像,进行图像对比分析,判断拼接图像是否合格,重复步骤,直至得到整体大场景图像,完成对自然资源中的森林资源进行面积测绘。本发明为一种自然资源管理用测绘仪及使用方法,图像拼接效果好,森林资源测绘更加精确。
