Embodiment 1

[0056] Such as figure 1 As shown, the embodiment of the present invention provides a kind of automatic measuring method of crop canopy uniformity, and this method comprises the following steps:

[0057] S1. Acquiring crop canopy images;

[0058] S2. Using binocular image reconstruction technology to calculate the three-dimensional point cloud data of the crop canopy image;

[0059] S3. Separating rowwise point cloud data of crops from the three-dimensional point cloud data;

[0060] S4. Calculate the basic data of crop canopy uniformity according to the row-wise point cloud data;

[0061] S5. Calculate the crop canopy uniformity index according to the basic data.

[0062] In the embodiment of the present invention, by acquiring the crop canopy image, the three-dimensional point cloud data of the crops is obtained, and then the point cloud data of the crops is obtained, and then the crop canopy uniformity index is calculated, and the crop canopy uniformity is judged by this in...

Embodiment 2

[0104] The embodiment of the present invention also provides a kind of automatic measuring device of corn canopy uniformity, comprises following module:

[0105] Obtain the canopy image module, and obtain the corn canopy image through the binocular stereo camera;

[0106] Calculating the three-dimensional point cloud data module, utilizing binocular image reconstruction technology to calculate the three-dimensional point cloud data of the corn canopy image;

[0107] Separate the row-to-point cloud data module, and separate the row-to-point cloud data of corn from the three-dimensional point cloud data;

[0108] Calculate the basic data module, according to the point cloud data of the row, calculate the basic data of the uniformity of the corn canopy;

[0109] The canopy uniformity index calculation module calculates the corn canopy uniformity index according to the basic data.

[0110] In summary, compared with the previous methods and devices, the method and device provided...

Abstract

The invention provides a method and device for automatically measuring crop canopy uniformity, and relates to the technical field of agriculture information. The method comprises the first step of obtaining a crop canopy image, the second step of calculating three-dimensional point cloud data of the crop canopy image by utilizing the binocular image reconstruction technology, the third step of separating row direction point cloud data from the three-dimensional point cloud data, the fourth step of calculating basic data of the crop canopy uniformity according to the row direction point cloud data, and the fifth step of calculating an index of the crop canopy uniformity according to the basic data. The method and device for automatically measuring the crop canopy uniformity achieve the purposes of continuously and automatically obtaining the index of the crop canopy uniformity, and are capable of automatically and continuously measuring the crop canopy uniformity in a lossless mode. Compared with a traditional method, the method has the advantages that human input is less needed, the automation degree is high, and the measurement result can comprehensively reflect the crop canopy uniformity and is not affected by a personal error or the experience of a measurement worker.

Description

technical field [0001] The invention relates to the technical field of agricultural information, in particular to an automatic measurement method and device for the canopy uniformity of crops. Background technique [0002] The uniformity of corn canopy includes two aspects, one is the uniformity of plant distribution in the field, and the other is the difference in traits between individual plants. Investigating the uniformity of maize canopy has certain practical and theoretical significance. From a practical point of view, when plants are unevenly distributed in the field, some plants can get sufficient light, nutrients, etc., while other plants lack these conditions, thus affecting the full play of the plant's production potential. In agricultural production, we have always tried our best to ensure the distribution and growth of field crops evenly from various aspects such as seed selection, soil preparation, sowing, and field management. What kind of process should the ...
