Timber yard wood information acquisition method, system and device based on unmanned aerial vehicle

Abstract

The invention belongs to the field of unmanned aerial vehicles and computer mode recognition, particularly relates to a timber yard timber information acquisition method, system and device based on anunmanned aerial vehicle, and aims to solve the problem that informatization management of a timber yard is affected due to the fact that timber piles of the timber yard are difficult to take picturescompletely. The method comprises the steps that an unmanned aerial vehicle is adopted to load a photographing device, and pictures are obtained and synthesized according to a planned path; adopting awood position recognition network to obtain a wood position vector and a single wood end face picture set, and counting the number of wood; obtaining a handwritten code position vector set and a handwritten code picture set by adopting a handwritten code position identification network; obtaining a handwritten code character set by adopting a handwritten code recognition network; and outputting the wood quantity and the handwriting code character set. According to the invention, the unmanned aerial vehicle is adopted to load the photographing device to acquire and synthesize pictures, so thatthe overall image acquisition of large objects or densely stacked objects is realized, the automatic information acquisition of special occasions is realized, and the low efficiency and high error rate of a manual intervention process are avoided.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles and computer pattern recognition, and in particular relates to a method, system and device for obtaining timber information in a timber yard based on an unmanned aerial vehicle. Background technique [0002] The freight yard refers to the place used to stack goods, and there are indoor freight yards and outdoor freight yards according to different products. The freight yard has the functions of cargo transportation, storage, loading and unloading, and delivery operations. In the management of the freight yard, the information entry and inventory of goods are important contents of the information management of the freight yard. Timber yards generally have a large area and do not have high requirements for the storage environment. They are generally outdoor yards. In order to ensure the smoothness of timber transportation and facilitate timber management, the timber yard will be divided into ...

Problems solved by technology

This kind of management method has the following problems: Individual employees use their power for personal gain, falsely report the quantity of wood and hand-write wood codes; the labor speed is slow and the efficiency is low; the degree of informatization is low, and when there is a dispute over the form, it must be resolved face to face. The wood yard located in the port customers from all over the world, causing great inconvenience
