| Abstract: | A new method was provided to obtain the image of leaf and survey the leaf area with rapidity and accuracy by means of digital camera based on the theory of getting leaf area with the true area each pixel spot standing for and the pixel quantity. This new method was suitable for accurate measuring of many kinds of plant leaf area whether it was the living leaf or it was picked up, especially for large amount of leaf area. This method had the characteristics of fast speed, accurate data and high precision. |
| Keywords: | leaf area measuring method digital photography graphical technique |
