Embodiment

[0039] Take the same Arabidopsis leaf at the same developmental time point as an example. Such as figure 1As shown, paste a black and white checkerboard grid on the left side of a card with a length of 7.0 cm and a width of 5.5 cm. The black grid and the white grid have the same specifications, and the length and width are both 1.0 cm. There is a blank space on the right side, and the size of the blank space is 3.0 cm. Multiply by 6.0 cm. Such as figure 2 As shown, the same Arabidopsis leaf selected 30 days after sowing and germination was placed in the blank space of the card at 4 different spatial angles; the photos taken by the iphone6 ​​mobile phone were selected by selecting four Arabidopsis leaves Create a bounding box with pixels. The pixel coordinates of the bounding box of the first picture are: (1634, 1363), (2050, 1875), (2050, 1363), (1634, 1875); the pixel coordinates of the bounding box of the second picture It is: (1383, 829), (1750, 1133), (1750, 829), (138...

Abstract

The invention discloses a method for calibrating blade shape space, and also discloses the application of the method in calibrating blade shape space. The method of the present invention can be used to reconstruct the space of the leaves of the plant, and the spatial calibration of the leaves can be carried out through the three-dimensional reconstruction technology, which can correct the shape space of the leaves, or make a standardized comparison of the same leaves at different development time points in terms of shape, to study its growth pattern.

Description

technical field [0001] The invention relates to a method for correcting blade shape space and its application. Background technique [0002] Leaf is an important organ of plant growth, and its morphological presentation is an important part of the "ideal plant shape" of plants. The allometric leaf expansion with age or developmental progress of plants will lead to the appearance of continuous leaf shape changes, resulting in the phenomenon of "heteroblasty". In addition, environmental regulation of leaf phenotypic plasticity is also achieved through leaf shape heterogeneity. [0003] There are many types of leaves, and lanceolate, oval, obovate, and oval are the classic description terms for several types of leaf shapes. Qualitative indicators such as aspect ratio and leaf shape index are typical traditional leaf shape description methods. This method can only roughly capture the leaf shape, but cannot accurately capture the continuous morphological changes accumulated du...
