Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a kind of calibration tray for testing seeds, to solve the problem that in the prior art, during the test of species, it is necessary to take pictures twice, that is, to take pictures of the calibration objects first, and then to take pictures once after putting the seeds in. , the position of the camera and the pallet may change during this process, causing measurement error problems

Embodiment 1

[0027] Such as Figure 1-3 As shown, a calibration tray for species testing includes a tray body 1, the tray body 1 is made of a light-transmitting material, and the tray body 1 is provided with a cavity for containing seeds, and the bottom surface of the cavity is On the horizontal plane, several calibration blocks 3 are arranged in the cavity, and the calibration blocks 3 are made of opaque materials. The outer wall of the tray body 1 is provided with ribs 2, and the ribs 2 are far away from the tray body 1. One end is chamfered.

[0028] The working principle of this embodiment is as follows: the present invention sets a cavity for containing seeds in the tray body 1 made of light-transmitting material, and the bottom surface of the cavity is a horizontal plane, so as to ensure that the seeds can appear closest to the seeds when they are projected. imaging. Set the calibration object directly in the cavity, and the calibration object is made of opaque material to ensure t...

Embodiment 2

[0030] Such as Figure 1-3 As shown, a calibration tray for species testing includes a tray body 1, the tray body 1 is made of a light-transmitting material, and the tray body 1 is provided with a cavity for containing seeds, and the bottom surface of the cavity is On the horizontal plane, a fixed column 4 is vertically arranged in the cavity, and a plurality of calibration blocks 3 are arranged in the cavity, and a through hole matching with the fixed column 4 and penetrating is provided on the described calibration block 3, and the calibration block 3 Through the through hole on the fixed column 4, it is convenient to take and place the fixed block, and also makes the fixed block more stable. The calibration block 3 is made of opaque material. The outer wall of the tray body 1 is provided with a rib 2 , and the end of the rib 2 away from the tray body 1 is chamfered.

Embodiment 3

[0032] Such as Figure 1-3 As shown, this embodiment is further optimized on the basis of Embodiment 1. The cavity in the tray body 1 of the present invention is rectangular, the calibration block 3 is a rectangular block, and the calibration block 3 penetrates through the fixing column through a through hole. 4 and close to the right angle in the cavity, the fixing block is placed on the right angle of the rectangular tray body 1, which not only makes the fixing block more stable, but also avoids placing the seeds on the tray so that the seeds are close to the fixed block, affecting the quality of observation.

Abstract

The invention discloses a calibration tray used for seed selection, and belongs to the technical field of seed selection. The calibration tray used for seed selection is used for solving problems in the prior art that two times of shooting are needed in seed selection process, shooting of a calibration object is carried out for the first time, and shooting is carried out for a second time after loading of seeds, and measuring error may be caused in the process of the two times of shooting because of the change of the relative positions of a camera and a tray. The calibration tray used for seedselection comprises a tray main body; a cavity used for storing seeds is arranged in the tray main body; the bottom of the cavity is designed to be the horizontal plane; a plurality of calibrating blocks are arranged in the cavity; the external side wall of the tray main body is provided with convex edges; one end of each convex edge far away from the tray main body is provided with a chamfer; the tray main body is prepared from a light transmission material; and the calibrating blocks are prepared from a lightproof material.

Description

technical field [0001] The invention relates to the technical field of species testing, in particular to a calibration tray for species testing. Background technique [0002] Seed testing is an analysis of the cross section of the seed, which can automatically obtain the number of grain rows, ear thickness, shaft thickness, and the average grain length and flatness on the cross section. When testing seeds, the traditional testing method is to first place a calibration object on the tray, use a fixed-position camera to take pictures, take out the calibration object, put seeds into the tray, and then take pictures. Then use the software of the seed test system to analyze the photographed size and actual size of the seeds by analogy according to the actual size of the calibration object and the data of the photographed size. However, in the process of traditional analysis, it is necessary to take two pictures, first to take pictures of the calibration object, and then to take ...
