Marigold Water State Detection System, Image Processing Platform Based On Embedded Systems

The Embeded System is a kind of computer system with special functions.When it is integrated with communication and network technology,it will enhance the ability and intelligent of instruments and devices'network and communication.With the constantly developing of the information technology and increasing of the requirement of users,the Embedded System is entering into all kinds of fields of national product gradually and used extensively.Based on this, the development of the image processing based on the embedded system will enforce the system of image processing's ability:communication,intercommunion,data procession and so on,at same time it can extent the range of application,adaptive faculty for different condition and request.The paper aims to study a design and technique of the image processing based on the architecture of embedded system.Aimed at the own characteristic of embedded system,designing a platform been endowed with more operating functions of embedded image processing with versatility.The author adopts the method of the embedded system design based on the basic functions and characteristic of image processing system,summarizing and comparing of the characteristic and new developments of the EOS for the ARM processor,and finally chooses the embedded Linux for the operating system of our platform,also tranplant it in the hardware platform. Aimed at the characteristic of Linux device driver's architecture,the author introduces how to develop the image capture and display,memory the data of an image,the programming method of that.Some base arithmetic of image processing,such as image gray transformation,image binary display,image filtering,edge detection,and image characteristic value.The presentation characteristic of the moisture demand of a farm crop(marigold) and health in its growth is withdraw,intact in character withdraw and quick processing is realized and a revaluation system model of the moisture demand of a farm crop in its growth and heath is built up. reliable data support for accuary of irrigation decision is provided,the aim of the precise quantitative of crop irrigation is achieved,and resources,energy and labor is saved.
