Embodiment Construction

[0079] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, the rectangular frame represents the processing steps, and the solid line represents the data processing flow.

[0080] A plant leaf feature analysis system based on scanned images, which comprises the following steps:

[0081] (1), image preprocessing

[0082] Perform image preprocessing on the leaf image obtained from the scanner to remove the noise existing in the image;

[0083] (2) Leaf image feature analysis and calculation

[0084] ①Threshold segmentation is performed on the preprocessed image by Dalu law to obtain a binary image;

[0085] ②Using morphological filters to process the obtained binary image to realize the automatic segmentation of leaves and petioles;

[0086] ③ Morphological gradient detection is performed on the image obtained after morphological filtering to obtain the contours of the leaves and peti...

Abstract

The invention discloses a system for analyzing plant leaf features based on image scanning. The system comprises the following steps of: (1), preprocessing an image; (2), analyzing and calculating the features of a leaf image; (3), matching with a leaf template; (4), clustering by color; and (5), analyzing specks. The system disclosed by the invention has the advantages that the automation level is high, manual operation in an analytic process is reduced, the automation degree is improved, and meanwhile, manual operation errors are avoided; the execution efficiency is relatively higher than that of a traditional canny operator and a traditional compass operator; the accuracy is higher; and mending operation can be automatically carried out on an incomplete leaf, and the mended area of the incomplete leaf can be automatically calculated.

Description

technical field [0001] The present invention relates to the field of morphological image processing and the field of botany, in particular to a detection method for segmenting and processing leaf images using digital morphological technology, extracting contour feature values ​​of images, performing template matching on leaves, color clustering and lesion spots analyze. Background technique [0002] As the main parameter for calibrating the physiological and biochemical reaction processes such as plant growth and development, growth, genetic characteristics, leaf area is widely used in agricultural scientific research services and production. In agricultural meteorological experiments, research and routine operational observations, leaf area is the main index to measure crop growth and growth dynamics, and can provide effective, scientific and applicable data for agricultural meteorological information services. The traditional methods of measuring leaf area mainly include ...
