Abstract

The invention discloses an extraction method of leaf color eigenvalue based on conventional low-resolution camera. The method includes the following steps: S1, firstly collecting the image informationof the blade by using a low-resolution camera, and then edge detection is carried out on the collected digital images, S2, cutting the digital image processed by the edge processing of S1 by using the image contour cutting and the color threshold algorithm, The invention separates out foreground target images, realizes automatic accurate and fast cutting of color leaf images collected by ordinarycameras and extracts transparent background images of targets, and relates to the technical field of plant physiology research. The method of the invention compares the influence of digital images with different resolutions and different sample sizes on leaf color characteristic parameters, and illustrates that the method has low requirements on equipment conditions, and can process data by appropriately reducing image resolutions or using a large computer.

Description

technical field [0001] The invention relates to the technical field of plant physiology research, in particular to a method for extracting leaf color feature values ​​based on conventional low-resolution cameras. Background technique [0002] The cost of equipment and software required for high-throughput phenotyping detection is often the bottleneck of large-scale research, such as mutant screening or quantitative genetic analysis. Some scholars have used hyperspectral methods to analyze the physiological and biochemical indicators and internal organs in plant leaves. Quantitative analysis of the changes in the field, but due to its harsh conditions of use and high cost, it is difficult to promote it in large-scale production. In recent years, with the increasing maturity of digital image technology and the popularization of high-resolution camera equipment, digital image Quantitative description of plant appearance phenotypic traits has become possible. Compared with hyper...
