Construction Of Platform-based 2.5D Agricultural Visual Management System

Qingfeng agricultural stations wa s selected for t he study, the research set up a technical route visualization agricultural station management platform. In the operating environm ent and workflow agricultural station wer e investigated, research, based on the analysis of the agricultural station to classify model, combined with 3ds Max, Pro / E, PhotoShop, SketchUp software model. Among them, in order to improve internet speed, reduce memory consumption, the 2.5-dimensional visualization scene m odel cut into many small pieces model, through the scene map background foreground segmentation and dynamically loaded realized only takes less memory resources and can sm ooth display o f large farm scene ef fect. Write farm three dimensional viewing algorithms and farm track observation algorithm, farm virtual positioning observation and scene dynamic display, rational integration of physical collision implement deep computing farm scene m ap, on this basis, co mbined with agricu ltural data managem ent, agricultural stations visual management platform.This article includes the following work:(1) according to farm log and electronic draw ings, in conjunction with 3ds Max, SketchUp, Photoshop, etc. to complete farm three-dimensional model, making good agricultural stations, farmland distribution, distributi on canals and other scenes to com plete the 2.5-dim ensional visualization big scene model, by 3dsMax achieve design and production 2.5D three-dimensional object model and the farm model.(2) Use Unity3 d engine algorithm s need to wr ite, to write the visual scene cut algorithm will create a good visu al map of the scene was cut to observe the surro unding topography and agricultural stations, dynamically loaded scene. Used by writing three-di mensional observation algorithm, use 2.5D Us ed farm model to achieve the ef fect of three-dimensional observation, follow-up observations by writing Used algor ithm to achieve farm by acquiring location information to show its state of m otion. By Unity3 d 2.5D layering technique with the use of the preparation of background depth detection algorithm, and Unity3 d physical collision technology integration, to achieve a three-dim ensional object collide with agricultural occlusion ef fect for post reclamation of agricultural management and relevant research personnel convenience.(3) To improve security for the protection of visual management system, by writing and reading XML database technology to achieve registration and si gn-on capabilities, so that each user can have their own account and passwor d, and improve the safety perfo rmance of the system.(4) Used visualization project file management system released into the Windows operating system mode of PC, M ac & Linux S tandalone form. Visualization makes farm management system can operate independently from the development environment.
