Precise Detection System Design Of Cucumber Anthracnose

The increasing of the agricultural product export business and the state vigorously implement of benefit farming policy promote the cucumber trend growing and developing rapidly.As one of cucumber leaf disease,anthrax can't be ignored in the area of growth,development,genetic and stable production of cucumber.At present,the anthrax detection based on experts with naked eyes,which can't provide effectively precaution and precise degree of disease for us.In this paper,it depends on actual demand of cucumber anthracnose disease detection,designed the detection system which can accurately determine the cucumber anthracnose disease level.So it enables the cucumber growers have a much better determination in surgical disease level and enhances the efficiency of prevention and treatment of anthrax disease,striving to promote the cucumber “pesticide less” “pollution-free” production,protecting environment and people's health.First of all,aiming at the problem of traditional leaf area measurement which need to be discussed and solved,we put forward a kind of portable cucumber anthracnose precision detection system design and implementation of the scheme,by consulting a large number of literature about leaf area calculation.Secondly,by using STM32 as the core of the embedded system as hardware platform,selecting OV7670 image sensor to measure blade for image acquisition,processing the image by the Matlab software which includes image segmentation,image gray and image denoising,image binarization processing,etc.,we get the cucumber anthracnose disease level by calculating the disease area and full leaf area ratio.Lastly,corresponding disease control measures is given by display the image of processed leaf and plant disease level and combining the expert assistant decision-making system.Based on the traditional measuring leaf area,cucumber anthracnose precision detection system makes the cultivation of cucumber cultivation improves work efficiently and increases the input-output ratio,by adding the anthracnose disease areacalculation ? calculatiing the cucumber anthracnose disease level according to the disease area and full leaf area ratio,which facilitates the anthracnose disease grades of accurate judgment.
