A method was presented of using CCD to measure the leaf area of plant, and a design is put forward of many kinds of scheme to constitute the measurement system. The characteristic of the system is that its hardware and software have no relation with each other by using standard image interface. Its hardware could be any of the following digital equipment using CCD to capture images, such as scanner, digital camera, and video A/D cards in combination with CCTV camera, and so on. Its software is designed to segment image, to calibrate the system and to measure leaf area in an alternative way. Results of experiment show that the leaf area of plant could be measured easily and accurately by this method. When the digital camera is used, the measurement could be done without destroying the plant. With a wide measurement range, it can be widely used in the fields of agriculture and forestry.
