Elk identification and form contour parameter extraction method based on unmanned aerial vehicle remote sensing

Abstract

A method for elk recognition and form contour parameter extraction based on unmanned aerial vehicle remote sensing comprises the following steps: taking an unmanned aerial vehicle remote sensing image as a processing material, firstly performing preprocessing and labeling, then establishing a target detection model, and then training by using an initial image and a labeling file; substituting the new remote sensing image into the target detection model to obtain target detection position information of the elk individuals on the new remote sensing image, importing the target detection position information and the target detection position information into a database to obtain an image data set, screening to obtain an elk individual image semantic segmentation training set, generating an individual mask, and establishing a semantic segmentation model; the method comprises the following steps of: acquiring an individual mask, training by using a training set and the individual mask, calling a new image data set into a model to obtain an individual prediction mask, performing gray scale and binarization processing, and converting a binarized graph into an elk contour vector information file to complete morphological contour parameter extraction. According to the design, the monitoring precision is high in a complex environment, elk form contour parameter extraction is facilitated, the use cost is low, and the functionality is high.

Description

technical field [0001] The invention relates to a monitoring method for elk, belonging to the field of animal monitoring, in particular to a method for elk identification and morphological contour parameter extraction based on remote sensing of unmanned aerial vehicles. Background technique [0002] Elk is a large-scale ungulate wetland species unique to China, and it is a national-level key protected wild animal. Due to human activities, climate change and other factors, wild elk populations became extinct in mainland China in the early 19th century. In 1985, China began to implement the elk reintroduction project. At present, the number of elk populations in my country has exceeded 8,000, and three large wild elk populations have gradually formed in Dafeng in Jiangsu, Shishou in Hubei and Dongting Lake in Hunan. small population. In 1991, Hubei Shishou Milu National Nature Reserve was established on the old Yangtze River Road in Swanzhou in the middle reaches of the Yangt...
