Portable field corn test instrument

Abstract

The invention discloses a portable field corn test instrument. The instrument comprises an objective table, a first image acquisition device, a second image acquisition device and a control mainboard,the objective table is used for bearing corn ears; the first image acquisition device is positioned below the objective table and is used for acquiring a side image of the corn ear; the second imageacquisition device is located beside the objective table, and the second image acquisition device is used for acquiring a tail end image of the corn ear; and the control mainboard is used for determining corn ear phenotypic character data according to the side images and the tail end images. According to the portable field corn seed test instrument, the corn ear phenotypic character data can be quickly acquired by adopting a machine vision technology without rotating corn to shoot and splice a plurality of side surface images, and the portable field corn test instrument has the advantages of labor saving and high efficiency, is light, small and exquisite, is convenient to carry, is compact in structure, is convenient for an operator to operate and carry with one hand, and can smoothly complete corn test work in fields.

Description

technical field [0001] The invention relates to the technical field of corn seed testing, in particular to a portable field corn seed testing instrument. Background technique [0002] Corn is an important food and feed industry raw material crop. Ear traits and grain shape of maize are important agronomic traits that determine the yield of maize. The acquisition of maize traits, that is, the indoor test of maize, is an important link in the process of maize breeding to evaluate the quality of breeding materials and determine the choice. Using manual measurement, the workload of data collection is huge, and there are problems such as slow speed, low efficiency, and poor accuracy. Research on the automatic extraction technology of corn cob traits will help reduce the workload of breeders and ensure the objectivity and accuracy of data. ,Improve work efficiency. [0003] At present, some researchers have used machine vision to detect the trait parameters of corn ears, put a s...

Ear traits and grain shape of maize are important agronomic traits that determine the yield of maize. The acquisition of maize traits, that is, the indoor test of maize, is an important link in the process of maize breeding to evaluate the quality of breeding materials and determine the choice. Using manual measurement, the workload of data collection is huge, and there are problems such as slow speed, low efficiency, and poor accuracy. Research on the automatic extraction technology of corn cob traits will help reduce the workload of breeders and ensure the objectivity and accuracy of data. ,Improve work efficiency

[0003] At present, some researchers have used machine vision to detect the trait parameters of corn ears, put a single corn on the rotating table, drive the corn ears to rotate, use a camera to take pictures of multiple sides of the ears and stitch the images, this method is inefficient and easy to damage corn kernels
