Description

Technical Field

[0001] The present invention relates to the field of early warning and monitoring of crop diseases, and in particular to a spectral image acquisition device and method for egg agricultural products. Background Art

[0002] Hyperspectral image nondestructive testing is one of the commonly used methods for testing agricultural products. Hyperspectral image nondestructive testing includes transmission method (light is only directed to the product once, and the image is collected from the backlit side of the product) and reflection method (the product is placed in the light field as a whole, and then the product image is collected). Compared with the reflection method, the transmission data of hyperspectral images of agricultural products (such as eggs, cooking oil, etc.) can better reflect the internal quality of agricultural products, and can also better avoid the influence of surface properties of agricultural products (dents, strong reflection of liquid surface, etc.) on spectral data, so as to obtain more real and reliable spectral data of agricultural products. The light source is the source of spectral data and plays an important role in transmission-based nondestructive testing of agricultural products.

[0003] The current agricultural product spectral image acquisition device has the following shortcomings: the light source is a surface light source, which cannot constrain the light within the required range, resulting in a large amount of light pollution; the transmission method can only detect flat agricultural products, and for ellipsoidal agricultural products such as eggs (hereinafter referred to as egg agricultural products) or irregular agricultural products, they are easy to slide and their light-receiving area may be too small, resulting in inaccurate or large errors in the collected spectral data; in the reflection method, in order to avoid the influence of the surface properties of agricultural products (dents, pollution) on the spectral data and achieve the same accuracy as the transmission method, it is necessary to collect six-view images of the product for corresponding processing, but egg-like agricultural products are easy to roll, resulting in the inability to accurately obtain six-view images of egg agricultural products, which in turn results in inaccurate or large errors in the collected spectral data. Summary of the invention

[0004] The present invention aims to provide an egg agricultural product spectral image acquisition device and acquisition method with small light pollution and good accuracy of collected spectral data, which solves the problem of large light pollution and poor data accuracy in existing egg agricultural product spectral detection.

The egg rack comprises a left vertical clamp, a right vertical clamp, a horizontal driving mechanism for driving the left vertical clamp and the right vertical clamp to separate and combine, an upper horizontal clamp, a lower horizontal clamp and a vertical driving mechanism for driving the upper horizontal clamp and the lower horizontal clamp to separate and combine, the left and right dimensions of the upper horizontal clamp and the left and right dimensions of the lower horizontal clamp are both smaller than the diameter of the egg, and when the left vertical clamp and the right vertical clamp clamp the egg, the upper horizontal clamp is located directly above the egg and the lower horizontal clamp is located directly below the egg; the specific process of collecting spectral images of egg agricultural products is: A, radially clamping the egg to keep the egg vertical; B, making the light source emit light; C, starting four spectrometer host probes to collect the six sides of the egg except the two clamped sides. image; D, axially clamp the egg to keep it vertical; E, start the remaining two spectrometer host probes of the six spectrometer host probes to collect images of the two sides of the egg that were not collected in step C; step A includes the following steps: A1, raise the lower horizontal clamping plate to be located between the left vertical clamping plate and the right vertical clamping plate; A2, place the egg on the lower horizontal clamping plate, so that the left vertical clamping plate and the right vertical clamping plate are closed to clamp the egg; A3, move the lower horizontal clamping plate downward, during which the clamping force of the left vertical clamping plate and the right vertical clamping plate on the egg is: the egg can rotate under the action of gravity with the contact point between the egg and the left vertical clamping plate and the contact point between the egg and the right vertical clamping plate as the fulcrum; A4, Continue to move the lower horizontal clamping plate downward until the egg is separated from the lower horizontal clamping plate. During this process, if the egg only moves downward with the lower horizontal clamping plate without generating rotational motion, increase the clamping force of the left vertical clamping plate and the right vertical clamping plate on the egg until the egg can be clamped by the left vertical clamping plate and the right vertical clamping plate and maintained in a vertical state; in step C, start the four upper, lower, front and back spectrometer host probes to collect images of the four sides of the egg; the specific process of step D is: close the upper horizontal clamping plate and the lower horizontal clamping plate to clamp the two ends of the egg, and then separate the left vertical clamping plate and the right vertical clamping plate; in step E, start the left and right spectrometer host probes to collect images of the left and right sides of the egg.

2. The egg agricultural product spectral image acquisition method according to claim 1, characterized in that: The method for making the left vertical clamping plate, the right clamping plate, the upper clamping plate and the lower clamping plate translate is the same; the method for making the left vertical clamping plate translate is: repeatedly pressing the left air bag, air enters the left sealed air cavity for pressurization, drives the left drive rod to extend out of the left sliding sleeve, and the left drive rod drives the left vertical clamping plate to move right; opens the left air cavity exhaust valve to relieve the pressure in the left sealed air cavity, the left spring drives the left drive rod to move toward the left sliding sleeve, and the left drive rod drives the left vertical clamping plate to move left.
