Embodiment 1

[0043] A method for obtaining stamen motion trajectory, comprising the following steps:

[0044] A1: Select the first frame image from the video image of flower blooming and delineate the stamen area, and determine the category and number of stamens;

[0045] A2: Obtain the values ​​of the RGB component and the HIS component of the stamen region for the selected stamen region;

[0046] A3: According to the RGB component and HIS component of the pistil area obtained in the step A2, perform statistics, and obtain the gray statistical peak value of the R, G, B, H, S, I component pixels of the selected pistil area r m , g m , b m , h m , s m and i m ;

[0047] A4: Carry out n-item polynomial fitting according to the peak value of grayscale statistics, and use the first integer valley value on the left and right sides of the peak value as the boundary of the segmentation pixels on both sides of the peak value, and then segment the stamen pixel for the selected stamen ar...

Embodiment 2

[0054] On the basis of embodiment 1, the above-mentioned acquisition method of stamen motion track also includes the following steps:

[0055] B1: Select the petal area at the same time as step A1;

[0056] B2: obtain the RGB component of petal area and the numerical value of HIS component for selected petal area;

[0057] B3: Perform statistics according to the RGB component and HIS component of the petal area obtained in the B2 step, and obtain the gray statistical peak value of the R, G, B, H, S, I component pixels of the selected petal area r f , g f , b f , h f , s f and i f ; Carry out n-item polynomial fitting according to the peak value of the gray level statistics, respectively use the first integer valley value on the left and right sides of the peak value as the boundary of the segmentation pixels on both sides of the peak value, carry out pixel segmentation to the selected petal area, segment the petal pixel, and The pixel area is divided by R, G, B, H,...

Embodiment 3

[0064] On the basis of embodiment 2, the stamen pixel area segmented in the A4 step is compared with the petal pixel area segmented in the B3 step, if the stamen pixel area is in the petal pixel area, it is determined to be the stamen pixel area, otherwise, Then it is judged as a noise area.

[0065] In the process of obtaining the stamen pixel area in this embodiment, some noise points that are not the stamen pixel area may appear, so by comparing the stamen pixel area with the petal pixel area, the stamen pixel area must be within the petal pixel area, so the obtained If the pistil pixel area of ​​is outside the petal pixel area, it is judged as a noise area and should be removed.

Abstract

The invention discloses a method for acquiring stamen motion track, comprising the following steps: A1: delineate the stamen area from the video image of flower blooming, and determine the type and number of stamens; A2: acquire stamens for the selected stamen area The value of the RGB component and the HIS component of the area; A3: perform statistics according to the RGB component and the HIS component of the acquired stamen area; A4: segment the stamen pixel according to the grayscale statistical peak value; A5: segment the stamen pixel and determine in step A1 Carry out cluster analysis on stamen category and number, and calculate the geometric center of each stamen in the image coordinate system; A6: Repeat steps A2 to A5 for subsequent frames of images; A7: According to each frame obtained in steps A5 and A6 The geometric center of stamens in the image coordinate system, and the trajectory of each stamen in the image coordinate system is obtained. Through the method of the invention, the trajectory of each stamen is tracked, and the pollination process of the stamen is studied, so that information with guiding significance for plant propagation and breeding can be obtained.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for acquiring the movement track of stamens. Background technique [0002] Flowers are the reproductive organs of plants and play an important role in the reproduction of the next generation. The pistil is directly related to bearing fruit and seeds, thus, the pistil is the main part of a flower. How to identify the dynamic trajectory of stamens is of great significance for understanding how the stamens of the two sexes are pollinated, the morphological development of flowers, and the formation of fruits. At present, there is no report on the dynamic acquisition of the stamen's motion trajectory. Contents of the invention [0003] The purpose of the present invention is to provide a method for obtaining stamen movement trajectory, which solves the problem that there is no research on stamen movement trajectory at present, and it is impossible to analyze stamen pollina...
