Problems solved by technology

[0004] Although the existing technology can obtain a large amount of image data, there is no method to estimate the damage degree of leaf gray spot disease based on these image data, so how to predict the leaf gray spot disease based on the image data of sandalwood leaves under complex It is an urgent problem to be solved to estimate the degree of harm

Embodiment 1

[0042] The proposal and development of the Internet of Things provides convenience for all walks of life, and the forestry Internet of Things technology also provides a new method for real-time monitoring of forestry. In the experiment, multiple field servos were set up in the forest where sandalwood was planted in six counties and cities (Yunlong, Longzhou, Maple, Longquan, Wenjiao, and Wenchang) in northern Hainan Province. The camera on each device could rotate 360° in the horizontal direction. , the vertical direction can be rotated 180°, and at the same time, each field server consists of an air temperature sensor, an air humidity sensor, a soil temperature sensor and a wireless local area network model. Real-time transmission to the server. When shooting with a fixed focal length lens and using a large aperture, the image size is 1024 × 768 pixels.

[0043] In the field of image processing, image segmentation has always been the focus and difficulty of image understandi...

Embodiment 2

[0098] The present embodiment provides a device for determining the damage degree of sandalwood leaf gray spot disease, including:

[0099] Get the unit for the whole tree image;

[0100] Segmentation unit for segmenting the leaf image from the whole tree image;

[0101] an acquisition unit for determining color features and texture features based on leaf images;

[0102] Determine the unit, (construct the damage degree model of gray spot disease according to the color characteristics and texture characteristics of sandalwood leaves, so as to determine the damage degree of gray spot disease.).

[0103] The acquisition unit is a field servo instrument, each field servo instrument includes a camera, and the camera can rotate 360° in the horizontal direction and 180° in the vertical direction.

[0104] For the working principle of each unit in this embodiment, refer to the description of Embodiment 1.

Abstract

An embodiment of the invention provides a method and a device for determining the harm degree of a sandalwood leaf grey speck disease, wherein the method and the device can realize prediction to the harm degree of the grey speck disease. The method comprises the steps of acquiring a whole tree image; segmenting a leaf image from the whole tree image; determining a color characteristic and a texture characteristic according to the leaf image; and determining the harm degree of the grey speck disease according to a sandalwood leaf grey speck disease harm degree pre-estimation model, the color characteristic and the texture characteristic. The device comprises an acquiring unit, a segmenting unit, an obtaining unit and a determining unit. The method and the device have technical effects of estimating the harm degree of the sandalwood leaf grey speck disease by an operator through the image which is transmitted from a field servo instrument, scientifically determining the harm degree of each sandalwood tree, applying different treatment solutions according to different harm degrees, controlling and treating the disease, minimizing the physical harm and the chemical harm to the sandalwood tree, and further ensuring high survival rate and growth quality of the sandalwood tree.

Description

technical field [0001] The invention relates to the field of forest managers and forest management, in particular to a method and device for determining the damage degree of gray spot disease. Background technique [0002] In the field of forest managers and forest management, there are many forest diseases and insect pests that can cause changes in leaves. For example, in the process of forest insect infestation, the leaves will be eaten by the insects, and in the process of forest disease, the leaves will wither. In a word, due to the frequent occurrence of pests and diseases in forests, and the degree of pests and diseases needs to be predicted, corresponding control measures can be taken according to the predicted degree of pests and diseases. [0003] For example, sandalwood is a precious tree species. Its wood is uniform and delicate, and it has a unique aroma. It has always been regarded as a treasure in incense making. Due to the extremely high economic and medicina...
