Problems solved by technology

[0003] Moreover, in the process of trait collection, all of them are usually collected manually, that is, directly measured by humans, but because some traits (for example, the branch angle between two branches) have large errors in manual collection, It leads to large human errors, and the data collected by different personnel cannot be directly compared and used, let alone formal statistical analysis

Embodiment

[0099] When the method of the present invention is implemented, a measurement system (hereinafter referred to as a handheld terminal) and a service terminal are required, and the handheld terminal is divided into functional modules and includes: a login module, a record book download module, a data collection module, a picture collection module, and a data checking module , data export module and data upload module; server functions include basic data formulation module, user management module and data review module.

[0100] The data formulation module of the server is used to formulate various basic data, including crop types, crop traits, trait grouping, collection templates, record books and other data, and the completed basic data is used for downloading to the handheld terminal. Take the definition of some traits of rapeseed and corn as an example: fill in the trait name, crop category, attribute group, data type, control type, and recording standard, and can be searched ...

Abstract

The invention discloses a character collecting method and system, and relates to the technical field of character collecting of crops. The method comprises the following steps that C1, images of corps to be collected are obtained and preprocessed; C2, the images after preprocessing are subjected to edge detection to obtain binary edge images; C3, all edge images are subjected to linear detection to obtain straight lines along the edges of branches of the crops to be collected; C4, the straight lines are subjected to fitting to obtain straight slopes representing two branches of the crops to be collected, and C5, according to the straight slopes of the two branches, branch angles of the crops to be collected are calculated. According to the character collecting method and system, partial characters are automatically collected, and accuracy of character collecting is improved.

Description

technical field [0001] The invention relates to the technical field of crop trait collection, in particular to a trait collection method and system. Background technique [0002] my country is a large agricultural production country. Whether it is variety selection, field production, or variety approval, in terms of field data collection and indoor plant testing, it is basically first to compile a record book in an Excel table, print it out, and store the collected trait data. Record it in a paper notebook. [0003] Moreover, in the process of trait collection, all of them are usually collected manually, that is, directly measured by humans, but because some traits (for example, the branch angle between two branches) have large errors in manual collection, As a result, human error is large, and the data collected by different personnel cannot be directly compared and used, let alone formal statistical analysis. Contents of the invention [0004] (1) Technical problems to ...
