Specifically, two buffer collectors of the double-buffer collector can be used for sequentially collecting spectral images, and the spectral images collected by each buffer collector can be spectral images obtained by splicing a set number of spectral images according to a set splicing mode.
The spectral image of the biological body to be detected may be a spectral image including the characteristics of the biological body to be authenticated, such as: a spectral image of a person's palm, a spectral image of a person's fingerprint, a spectral image of a person's face, etc.
In addition, after any one buffer collector finishes the collection of the spectral image, the other buffer collector can be immediately used for collecting the spectral image, and the collected spectral image can be used for the subsequent steps.
Step S110: and when the target spectrum images collected by one target buffer collector in the double buffer collectors reach the set number, inputting the spliced spectrum images into a spectrum detection model to obtain the detection result of the spliced spectrum images.
Specifically, any one of the double-buffer collectors that collects a set number of spectral images may be used as a target buffer collector, spectral images collected by the target buffer collector may be used as target spectral images, and then spectral images obtained by splicing the set number of target spectral images may be input to the spectral detection model to obtain a detection result of the spliced spectral images output by the spectral detection model.

Specifically, the splicing mode may be determined according to actual conditions, and taking two spectral images with a set number as an example, the two spectral images may be spliced up and down, or left and right, or the two spectral images may be spliced after being adjusted to a certain extent.
And determining the detection result corresponding to each target spectral image according to the detection result of the spliced spectral image obtained in the step and the splicing mode of the target spectral image.
Step S130: and for each target spectral image, performing spectral recognition on the target spectral image according to a detection result corresponding to the target spectral image to obtain a spectral recognition result of the target spectral image.

Specifically, for each buffer collector, the process may include the following steps:
s1, establishing a storage space according to the set number of spectral images, wherein the storage space is provided with a plurality of storage positions.
Specifically, a storage space may be established according to a set number of spectrograms, the storage space may have a plurality of storage locations, and each storage location may store a corresponding spectral image.
And S2, splicing each spectral image to a corresponding storage position in the storage space according to a set splicing mode to obtain a spliced spectral image.
Specifically, for each spectral image, the spectral image can be spliced to the corresponding storage position in the storage space according to the set splicing mode, and after the set number of spectral images are all spliced to the corresponding storage positions, the spliced spectral image can be obtained.
According to the scheme, the storage space is established for storing the spliced spectral images, the storage space can be prevented from being established for each spectral image, and therefore the process of integrating the spectral images and splicing the spectral images can be omitted.
In some embodiments of the present application, step S120 is introduced, and a detection result corresponding to each target spectral image is determined according to the set stitching manner and the detection result of the stitched spectral image.
Specifically, the process may include the steps of:
s1, determining the region of each target spectral image after splicing according to the set splicing mode.
Specifically, the region of each target spectral image may be determined in the spliced spectral images, wherein the same target spectral image may correspond to different regions in different splicing manners.
S2, determining the detection result of each region of the spliced spectral image based on the detection result of the spliced spectral image, and taking the detection result of each region as the detection result of the target spectral image corresponding to the region.
Specifically, the detection result of the spliced spectral image may include the detection result of each target spectral image, so that the detection result of the region corresponding to each target spectral image may be determined, and the detection result of the region may be used as the detection result of the target spectral image.
Next, a process of determining a detection result of each target spectral image according to the stitching manner will be described in detail with reference to fig. 2.

And (4) establishing a plane coordinate system by taking the vertex of the upper left corner of the detection result of the spliced spectral image as a coordinate origin. Because the two target spectral images have the same size and are spliced left and right, the corresponding area of each target spectral image can be determined in the range of the abscissa.
Referring to fig. 2, a region having an abscissa range of [0,width) may be taken as the region of the first target spectral image, and a region having an abscissa range of [ width,2 width) may be taken as the region of the second target spectral image.
And then determining the detection results of the two regions in the detection results of the spliced spectral images based on the determined region range, wherein the detection result of each region can be used as the detection result of the target spectral image corresponding to the region.

and carrying out spectrum recognition on the single spectrum of the target spectrum image by using a target recognition threshold higher than the initial recognition threshold corresponding to the single spectrum to obtain a spectrum recognition result of the target spectrum image reaching the target recognition threshold.
Specifically, each spectrum may have a corresponding initial recognition threshold, and if a single spectrum in the detection result reaches the initial recognition threshold corresponding to a certain spectrum, the initial recognition threshold may be increased to a target recognition threshold, where the increased amplitude may be determined according to an actual situation, for example: raise the initial recognition threshold by 20%, 30%, or 40%, etc.
Then, the single spectrum may be identified by the target identification threshold, and if the identification result of the single spectrum reaches the target identification threshold, the single spectrum included in the target spectrum image may be considered as the spectrum corresponding to the target identification threshold.
S2, for a detection result, a target spectrum image with a plurality of spectrums is present:
and performing spectrum recognition on a plurality of spectra of the target spectrum image, and if the first two recognized recognition results are consistent, determining the first two recognized recognition results as the spectrum recognition results of the target spectrum image.
Specifically, for the identification of a plurality of spectra included in the target spectral image, each spectrum may have a corresponding initial identification threshold, and if the initial identification threshold of a certain spectrum is reached, the spectrum may be considered as the spectrum corresponding to the initial identification threshold.
If the first two identified identification results are consistent, that is, the first two identified spectra are the same spectrum, the identification results of the first two identified spectra can be used as the identification results of the target spectral image.
It can be seen from the foregoing solutions that, in the embodiments of the present application, different identification strategies are applied for detection results in which a single spectrum and multiple spectra exist, and thus, a variable situation can be flexibly dealt with.
In consideration of the fact that the acquired spectral images are not necessarily all spectral images of the organism to be authenticated, and may also be spectral images of the prosthesis, in the embodiment of the present application, before performing spectral recognition on the target spectral image, an anti-counterfeiting detection process for the spectral images may be added, so as to eliminate interference of the prosthesis.
Specifically, the process may include the steps of:
and inputting a detection result corresponding to each target spectral image into an anti-counterfeiting identification model to obtain a true and false judgment result of the target spectral image.
Specifically, the detection result corresponding to each target spectral image may be input to the anti-counterfeiting recognition model to obtain the predicted anti-counterfeiting score of the detection result of each target spectral image, and for the detection result reaching the set anti-counterfeiting score threshold, the target spectral image corresponding to the detection result may be used as the spectral image of the real organism, otherwise, the target spectral image may be used as the spectral image of the prosthesis.
The anti-counterfeiting identification model can be realized based on various methods, such as: the anti-counterfeiting identification model can be obtained by using the anti-counterfeiting identification model based on the resnet18 and modified according to actual conditions, and can be realized by other optional methods.
Furthermore, one or more spectral anti-counterfeiting may be performed for the spectra contained in the target spectral image, such as: anti-counterfeiting can be performed for the visible light spectrum and/or for the near infrared spectrum, as well as other optional spectrum anti-counterfeiting.
After the anti-counterfeiting identification, performing spectrum identification on the target spectrum image, which may include:
and carrying out spectrum recognition on the target spectrum image with the result characterized as a real organism to obtain a spectrum recognition result of the target spectrum image.
Specifically, the process of performing spectrum recognition on the target spectrum image whose result is characterized by the real organism may refer to the process of performing spectrum recognition on the target spectrum image described above, and details are not repeated here.
In some embodiments of the present application, a process of inputting the detection result corresponding to the target spectral image to an anti-counterfeit recognition model to obtain a true and false determination result of the target spectral image is described, and a training process of the anti-counterfeit recognition model is described next.
Specifically, the process may include the steps of:
s1, training spectral images containing prosthesis characteristics of different prosthesis types are obtained.
In particular, for different types of prostheses, spectral images containing their features may be acquired as training spectral images.
S2, inputting the training spectral image marked with the prosthesis type into the anti-counterfeiting recognition model to obtain a predicted prosthesis type output by the anti-counterfeiting recognition model.
Specifically, the anti-counterfeiting recognition model can output the predicted prosthesis type corresponding to the prosthesis characteristic according to the prosthesis characteristic contained in the training spectral image.
And S3, updating the parameters of the anti-counterfeiting recognition model by taking the output prosthesis type which is predicted to approach the prosthesis type marked by the training spectral image as a training target.
Specifically, the parameters of the anti-counterfeiting identification are trained and adjusted for multiple times, the anti-counterfeiting identification model with updated parameters can be obtained, and the accuracy of the output predicted prosthesis type can reach the set prediction accuracy threshold.
According to the scheme, the anti-counterfeiting recognition model can distinguish different types of prostheses after training, can cope with different types of prosthesis attacks, and improves the stability and safety of the spectrum recognition process.
