Plant leaf area is an important index for studying plant physiology and biochemistry, genetic breeding and crop cultivation techniques. To establish a convenient, rapid and accurate method for leaf area determination. The characteristics of existing methods for measuring plant leaf area are analyzed, and a digital image processing method for gait analysis is proposed to obtain leaf image. Based on this principle, a new method for fast acquisition of plant leaf image and accurate measurement of leaf area using digital camera is presented. Digital image processing technology, including template matching, sub-pixel and motion estimation technology, is used to identify and track the movement of markers. Using the corrected image to calculate the blade area, the measurement accuracy is improved. Studies have shown that digital image processing can accurately determine plant leaf area, which has the advantages of time saving and labor saving. Therefore, this method is worthy of promotion and application in the determination of plant leaf area. Provide reference for the development of plant leaf area measurement and blade image processing integration software.
