In order to realize non-loss measurement of Characters on plant leaves, a method based bilinear mapping has been advanced. Firstly, Bilinear space transformation is used to mapping the pixels position between distortion image and original image, secondly, calculating the value of leaf-area and related values. The validity of measurement has not been influenced by size and figure differential, the experiment shows that distort image of plant leaves can be corrected, and effective area can be extracted commendably, the accuracy can reach to more than 99% when using this method to correct the images of plant leaves. the results shows that the method of technology of computer vision is accurate, simple and convenient in measuring leaf area, which is very important to the collecting and use of plant information of digital agriculture.
