Abstract:Three-dimension green quantity, also named virescence three-dimension quantity,refers to the spatial volume formed by stem and leaf of a plant. The study of the measurement for three-dimension green quantity is a basis precondition for the estimation of virescence urban environmental benefit, and also is an important part for urban ecosystem study. The present paper purports to take the color infrared aerial remote sensing image as its main research data. The basic method of quantitative remote sensing is i...
