Embodiment 1

[0021] Embodiment 1: Determination of fractal characteristics of plants under different shooting distances and angles:

[0022] The digital camera 1 is fixed on the telescopic tripod 2, and the plants to be photographed 3 Haloxylon 2-year-old seedling plants are fixed between the digital camera 1 and the 2m×2m white background board 4, and the white background board 4 is provided with a Calibration object 5; plant 3 rotates 360° and cannot move forward, backward, left, right, up and down; digital camera 1 moves up, down, left, and right; white background plate 4 moves forward and backward;

[0023] First, place the plant 3 Haloxylon 2-year-old seedling plants to be photographed between the fixed digital camera 1 and the white background plate 4, adjust the digital camera 1, and set different shooting distances and shooting angles to collect Haloxylon 2-year-old seedling plants respectively According to Table 1, different shooting distances and shooting angles are set to obtain...

Embodiment 2

[0030] Embodiment 2: Measuring the fractal characteristics of plants under different shooting distances and shooting heights:

[0031] Arrange the shooting device in the same way as in Example 1, use the same Haloxylon 2-year-old seedling plant, set different shooting distances and shooting heights to collect images of Haloxylon 2-year-old seedling plants respectively, and set different shooting distances and shooting heights according to Table 1. Acquisition of images of shuttle seedlings;

[0032] After taking pictures with different combination settings, the length of each branch of the plant was measured to obtain the correlation between the fractal characteristic parameter values ​​of Haloxylon 2-year-old seedlings and the branch length of Haloxylon under different shooting distances and angles;

[0033] Use image processing software to crop the acquired image and convert it into a binary image;

[0034] Use the compiled plant fractal feature calculation program to calcu...

Abstract

The invention relates to a method for obtaining a shrub branch length based on a digital image technology. A device capable of accurately obtaining plant fractal characteristics is designed through the method by using digital images obtained by a digital camera, a computer image processing method and a fractal characteristic method, and a method for obtaining a shrub branch length according to the dimensions of a plant fractal box is given out; and the plant branch length can be quickly, completely and accurately obtained through the analysis of the image fractal characteristics. The method provided by the invention provides a novel train of thought to quantitatively research the growth dynamic characteristics of an over-ground part of a desert shrub, has a great significance to the promotion of the development and completion for accurately and quickly obtaining the dynamic growth monitoring statuses of desert plants in the wild, and overcomes the shortcoming in a method for continuously measuring the growth of over-ground organs of plants.

Description

technical field [0001] The invention relates to a method for obtaining plant branch length by analyzing shrub fractal characteristics based on digital image technology. The method has important practical value for non-destructive investigation of plant growth dynamics. Background technique [0002] Desert vegetation is an important part of the desert ecosystem. The response and adaptation of its growth and development to the desert habitat, especially the response and adaptation of the growth and development of desert plants to water conditions, and the ecological restoration and vegetation succession of the desert ecosystem in arid areas research is of great significance. Therefore, studying the growth dynamics of desert plants and their responses to changes in habitat conditions is the core problem that needs to be solved urgently. At present, most of the investigations and studies on desert plants use destructive methods, which cannot accurately obtain the continuous gro...
