Ear image information acquisition device and method

Abstract

The invention provides an ear image information acquisition device and method. Specifically, the device comprises: a first clamping rod, a second clamping rod, a first control structure, a second control structure symmetric with the first control structure longitudinally, a first support and cameras. The first clamping rod and the second clamping rod are vertically arranged at the periphery of ears. The first control structure comprises a first pulling sliding block, a first connecting block, a second pulling sliding block and a second connecting block, and the first pulling sliding block is connected to one end of the first connecting block, the other end of the first connecting block is connected to the upper end of the first clamping rod, the second pulling sliding block is connected to one end of the second connecting block, and the other end of the second connecting block is connected to the upper end of the second clamping rod. The first control structure and the second control structure are both arranged on the first support. The cameras are disposed around the ears to acquire ear image information. The device and the method provided by the invention can guarantee that ears of different forms stand uprightly at the center surrounded by the cameras, and can improve the precision and efficiency of ear image acquisition.

Description

technical field [0001] The invention relates to the field of image information acquisition, in particular to a device and method for acquiring ear image information. Background technique [0002] Corn ear seed testing is an important link in the process of maize breeding to evaluate the quality of breeding materials and to decide whether to choose or not. This link includes testing corn ear length, ear thickness, ear row number, row kernel number, bald tip and other parameters. Traditional indoor testing mainly uses manual methods to manually measure various parameters of all samples one by one. The measurement efficiency of this method is low, and there are manual errors in the measurement process, which cannot meet the large-scale test measurement requirements. It is an important method to solve this problem to realize the automatic test of corn ears. [0003] The existing corn ear seed testing devices are mainly single-camera rotation shooting and multi-camera surround ...

AI Technical Summary

Problems solved by technology

[0003] The existing corn ear seed testing devices are mainly single-camera rotation shooting and multi-camera surround shooting. When a single camera is used for static shooting, only one side image of the corn ear can be obtained, and the seed testing parameters of the entire corn ear can be estimated through analysis. The obtained The parameter accuracy has certain limitations; using a single camera for rotating shooting limits the measurement efficiency of the system

With multi-camera surround shooting, all the shape information of the ears can be obtained in one shot. However, multi-camera surround shooting requires the corn to stand upright and the center of the camera surround. The existing device cannot guarantee that test samples of different sizes can stand upright, which will lead to Affect the quality of image acquisition, and affect the accuracy and efficiency of test parameter measurement
