Abstract In the era of rapid development of modern technology, agriculture as the foundation of our national economy, is also the way of survival for the majority of agricultural laborers。 How to improve the efficiency of agricultural production, to effectively detect agricultural crops, and to control the state of growth of the plant in time are the main problems of agriculture in China。 Nowadays, as the science and technology gradually grow, digital image processing technology has been widely used in agricultural engineering technology areas about crop analysis, test and measurement。 Using the digital image technology to improve traditional agriculture and to promote the scientific and technological level of agricultural production, is the consensus of a growing number of agricultural laborers。
Analysis of tomato stem and leaf’s images is carried out followed by image pretreatment using MATLAB。 Parameters of leaf area and stem length/width can be worked out by comparing the pixels of the target image and the reference object, and use CAD to validate data and analyze error in order to determine the growth state of the plant。 According to this study, it can be more real-time, convenient and efficient to detect the growing status information of greenhouse plants, and be more accurate to regulate and control the crops。
