Embodiment Construction

[0028] The following embodiments can further illustrate the present invention, but do not limit the present invention in any way.

[0029] Such as figure 1 As shown, a plant recognition device with a high recognition rate includes an image acquisition unit, an image preprocessing unit, a feature extraction unit and a classification unit:

[0030] 1. Image acquisition unit: The image acquisition unit is a module used to acquire external images. In this device, images are acquired mainly through three commonly used image acquisition devices such as scanners, mobile phone cameras, and digital cameras. No matter what kind of equipment is used to obtain images, if the following requirements are mainly met, the device can be used for plant identification; Note: . The background should not be complicated. It is difficult to accurately segment the leaves under the complex background, which will easily lead to recognition failure. . Try to keep the leaves intact and representative...

Abstract

The invention discloses a plant identification method and device with a high identification rate. The method includes the specific steps that firstly, a plant organ digital image is collected through an image collection unit and serves as a test sample; secondly, the sample is preprocessed to obtain a gray level image; thirdly, feature extraction is carried out on the gray level image through a pulse-coupled neural network so as to obtain an entropy sequence capable of reflecting the gray level image; a high plant identification rate can be obtained through a support vector machine classifier with the entropy sequence as a main feature and the morphological features as auxiliary features. The plant identification method and device can achieve simple and accurate identification of large sample data (with a large number of plant species to be distinguished) and have a high identification rate and strong adaptability; tests on existing databases verify that the accuracy rate of the plant identification method and device reaches more than 98%.

Description

technical field [0001] The invention relates to a plant recognition method based on leaf images, in particular to a plant recognition method and device with high recognition rate. Background technique [0002] There are many classification methods currently used for plants, which can be roughly divided into classical morphological classification methods and modern classification methods. Modern plant classification methods require high technical expertise, such as plant cytotaxonomy, phytochemical taxonomy, plant serotaxonomy, and plant genetics. For non-professionals, these classification methods are complicated to operate, difficult to grasp or not practical, let alone suitable for field work environment. Compared with modern classification methods, the classical plant morphological classification method is easier to grasp, and is suitable for the identification of living plants in the wild. The classical morphological classification method is to classify plants by obser...
