Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall be protected by the present application.
In the multispectral biopsy technique, a light source is generally designed, and then data analysis is performed according to multispectral data under the light source to detect a living tissue.
At present, when designing a light source, the following two aspects are generally considered: first, considering the uniformity of the light source and the requirement for the divergence angle of the light source, it is desirable that the divergence angle of the light source can be larger and the light source can be more uniform; second, the design of the light source structure is considered.
However, at present, only the spectral data analysis can be performed on the multispectral data obtained under the designed light source, and the obtained multispectral data is limited by the number of different lights in the light source. That is, the light source includes light beams with different wave bands, the obtained multispectral data includes corresponding spectral data with different wave bands, the comprehensiveness of the multispectral data is low, the analysis result of the analysis of the spectral data is not comprehensive, and when the multispectral data is applied to the multispectral biopsy technology, the precision of in-vivo detection is limited.
Based on the above, the application provides a method for determining spectral data, which obtains spectral data corresponding to other light beams except the existing light beam in the light source under the condition that different light beams in the light source are limited, thereby enriching the multispectral data.
In order to explain the technical means of the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart illustrating an implementation process of a method for determining spectral data, which can be applied to a terminal and is applicable to a situation that rich spectral data is required. The terminal may be a terminal device such as a computer, or may also be a multispectral detector with a certain computation capability, or a biopsy device using a multispectral biopsy technique, or the like.
Specifically, the method for determining the spectrum data may specifically include the following steps S101 to S102.
Step S101, acquiring a plurality of initial spectrum data obtained when a plurality of light-emitting light sources with different light-emitting wave bands respectively irradiate an object to be detected.
The object to be detected can be living bodies such as human beings, animals and the like, and can also be other objects needing to acquire multispectral data.
In some embodiments of the present application, a plurality of light emitting sources with different light emitting bands may be used to irradiate an object to be detected respectively, and a plurality of initial spectrum data obtained when the plurality of light emitting sources with different light emitting bands irradiate the object to be detected respectively may be obtained. That is, each initial spectral data corresponds to one luminescence band.
In some embodiments of the present application, the terminal may be connected with a light emitting source and a multispectral camera. The terminal can control each light-emitting source in the plurality of light-emitting sources to respectively irradiate the object to be detected in different first acquisition periods of the multispectral camera; and shooting in each first acquisition period by using a multispectral camera to obtain initial spectrum data.
In some embodiments of the application, the terminal may control each of the plurality of light sources to emit light in one collection period, to irradiate the object to be detected, and control the multispectral camera to shoot the object to be detected in a plurality of first collection periods, and based on reflected light obtained by the object to be detected by reflecting the emergent light of each light source, the multispectral camera may obtain a plurality of initial spectral data in each first collection period. That is, each first acquisition cycle corresponds to one of the plurality of light emitting sources.
Specifically, the terminal may respectively control each of the plurality of light sources to emit light according to the plurality of light source control timings, and control the multispectral camera to shoot according to the camera acquisition timing.
For example, the plurality of light-emitting light sources may include a light source a and a light source B, fig. 2 shows a light source control timing sequence of the light source a and the light source B, and a camera acquisition timing sequence of a multispectral camera, the light source a and the light source B are controlled to emit light respectively by different light source control timing sequences shown in fig. 2, and initial spectrum data corresponding to the light source a emitting light may be acquired in the first acquisition cycle 21, and initial spectrum data corresponding to the light source B emitting light may be acquired in the first acquisition cycle 22.
In other embodiments of the present application, the light-emitting source and the multispectral camera may also be controlled by a worker, so that each of the plurality of light-emitting sources illuminates the object to be detected in different first acquisition periods of the multispectral camera, and the multispectral camera performs shooting in each first acquisition period to obtain the initial spectral data.
And step S102, combining the plurality of initial spectrum data to obtain one or more target spectrum data.
The light source light-emitting waveband corresponding to the one or more target spectrum data is different from the light-emitting waveband of the plurality of light-emitting sources.
In some embodiments of the present application, the terminal may combine any two or more initial spectral data in the plurality of initial spectral data, each combination may obtain one target spectral data, and the terminal may obtain at least one target spectral data through a plurality of different combinations.
Specifically, as shown in fig. 3, in some embodiments of the present application, the combining the plurality of initial spectral data to obtain one or more target spectral data may include the following steps S301 to S303.
Step S301, obtaining reference spectrum data obtained when the object to be detected is not irradiated by the plurality of light emitting sources.
In some embodiments of the present application, the reference spectrum data may refer to reference spectrum data obtained when the object to be detected is irradiated by ambient light.
In some embodiments of the present application, the terminal may control each of the plurality of light sources not to illuminate the object to be detected in the second acquisition period of the multispectral camera, and acquire the reference spectral data acquired by the multispectral camera in the second acquisition period.
Specifically, the terminal may respectively control each of the plurality of light sources to emit light according to the plurality of light source control timings, and control the multispectral camera to shoot according to the camera acquisition timing.
Continuing with fig. 2 as an example, when the light source a and the light source B are controlled to emit light respectively by the light source control timing control shown in fig. 2, the reference spectrum data may be acquired in the second acquisition period 23.
As can be understood by referring to fig. 2, the multispectral camera may be controlled to capture images by one camera, and the plurality of light-emitting sources may be controlled to emit light by the light-emitting source light-emitting control in which the number of light-emitting sources is the same as that of the light-emitting sources, so that the reference spectrum data and the plurality of initial spectrum data may be obtained.
Step S302, calculating spectrum data corresponding to each light-emitting wavelength band based on the reference spectrum data and the plurality of initial spectrum data.
Specifically, the plurality of light-emitting light sources include a light source a and a light source B, and assuming that reference spectrum data acquired by the terminal is data1, initial spectrum data obtained when the light source a irradiates an object to be detected is data2, and initial spectrum data obtained when the light source B irradiates the object to be detected is data3, the terminal may calculate that the spectrum data corresponding to the light-emitting waveband corresponding to the light source a is data _ a-data 2-data1, and the spectrum data corresponding to the light-emitting waveband corresponding to the light source B is data _ B-data 3-data 1.
In practical applications, the same number of spectrum data can be obtained through calculation according to the number of light-emitting bands corresponding to the plurality of initial spectrum data in the same manner.
Step S303, combining the spectral data corresponding to each light-emitting waveband to obtain one or more target spectral data.
In some embodiments of the present application, any two or more spectral data in the spectral data corresponding to each light-emitting wavelength band are combined to obtain a corresponding target spectral data. The target spectral data obtained by combination is different based on different spectral data. Based on this, the terminal can obtain at least one target spectrum data.
Specifically, the plurality of light-emitting sources may include a first light-emitting source having a light-emitting wavelength band of a first light-emitting wavelength band and a second light-emitting source having a light-emitting wavelength band of a second light-emitting wavelength band. The above-mentioned combining the spectrum data corresponding to each light-emitting waveband to obtain one or more target spectrum data may include: and combining the spectral data corresponding to the first light-emitting waveband with the spectral data corresponding to the second light-emitting waveband to obtain target spectral data corresponding to a third light-emitting waveband.
The third light-emitting waveband is the superposition of the first light-emitting waveband and the second light-emitting waveband.
Specifically, in the foregoing example, if the light source a is a first light emitting source with a light emitting band being a first light emitting band, and the light source B is a second light emitting source with a light emitting band being a second light emitting band, the terminal may obtain the target spectrum data _ AB + data _ B corresponding to the third light emitting band by combining the spectrum data _ a corresponding to the first light emitting band and the spectrum data _ B corresponding to the second light emitting band.
Similarly, the manner of combining three or more initial spectrum data may refer to the description of the combination manner shown in fig. 3, which is not described herein again.
Further, in some embodiments of the present application, the target multispectral data may be obtained based on the initial spectral data and the target spectral data, and the obtained target multispectral data not only includes spectral data corresponding to a light-emitting waveband of each light-emitting light source, but also includes spectral data corresponding to other light-emitting wavebands other than the light-emitting waveband of each light-emitting light source.
In the embodiment of the application, a plurality of initial spectrum data obtained when a to-be-detected object is irradiated by a plurality of light-emitting sources with different light-emitting wavebands are obtained, and then the plurality of initial spectrum data are combined to obtain one or more target spectrum data, so that the target spectrum data of a new light-emitting waveband different from the existing light-emitting waveband can be added on the basis of the initial spectrum data corresponding to the existing light-emitting waveband, and the spectrum data are enriched. Multispectral data obtained by combining the initial spectral data and the target spectral data are richer, so that the analysis result of analyzing the obtained multispectral data is more comprehensive, and the obtained multispectral data is applied to a multispectral biopsy technology, so that the accuracy of in-vivo detection can be improved.
Meanwhile, in practical application, based on the limitation of hardware conditions, only a light-emitting light source with a specific light-emitting waveband can be used, and the method provided by the application can be used for obtaining the spectral data corresponding to a new light-emitting waveband except the specific light-emitting waveband, so that the influence of hardware on the living body detection can be avoided to a certain extent.
In practical application, a worker can select a light-emitting waveband corresponding to each light-emitting source in the plurality of light-emitting sources according to actual requirements.
Specifically, in some embodiments of the present application, the plurality of light emitting sources may include a first light emitting source having a light emitting wavelength band of a first light emitting wavelength band and a second light emitting source having a light emitting wavelength band of a second light emitting wavelength band, in consideration of limitations of hardware conditions; the first light-emitting waveband is a visible light waveband, and the second light-emitting waveband is a near-infrared waveband.
More specifically, one of the light emitting sources may be a common led light source or a full spectrum light source simulating sunlight, and is configured to emit a light beam with a light emitting waveband being a visible light waveband; the other light source can be a halogen lamp light source after filtering out the visible light wave band or a combined light source of near infrared led light sources, wherein the combined light source of the near infrared led light sources can emit light beams with the central wavelengths of 740nm, 840nm and 940nm respectively.
In other embodiments of the present application, in consideration that the subsequently obtained multispectral data can be applied to in vivo detection, the plurality of light-emitting sources may include a first light-emitting source having a light-emitting wavelength band of a first light-emitting wavelength band and a second light-emitting source having a light-emitting wavelength band of a second light-emitting wavelength band; the reflectivity of a light beam of a first light-emitting waveband emitted by a first light-emitting source on the epidermis of the object to be detected is smaller than a first reflectivity threshold value; the reflectivity of the light beam of the second light-emitting waveband emitted by the second light-emitting light source on the epidermis of the object to be detected is larger than the second reflectivity threshold value.
Specifically, the specific values of the first reflectivity threshold and the second reflectivity threshold may be adjusted according to actual conditions, and the first reflectivity threshold is smaller than the second reflectivity threshold. When the reflectivity of the light beam of the first light-emitting waveband emitted by the first light-emitting source on the epidermis of the object to be detected is smaller than the first reflectivity threshold value, it is indicated that the reflectivity of the epidermis of the object to be detected to the light beam of the first light-emitting waveband is lower. When the reflectivity of the light beam of the second light-emitting waveband emitted by the first light-emitting source on the epidermis of the object to be detected is larger than the second reflectivity threshold value, the reflectivity of the epidermis of the object to be detected to the light beam of the second light-emitting waveband is higher.
In some embodiments of the present application, the first light emitting source may be a narrow wavelength band light source for emitting a light beam with a first light emitting band of 420nm to 440nm, a light beam with a first light emitting band of 550nm to 590nm, or a light beam with a first light emitting band of 960nm to 980nm, according to a wavelength band ratio algorithm and a biopsy characteristic wavelength, and the light beam with the first light emitting band has a low reflectivity at real skin. The second light source may be another narrow-band light source for emitting a light beam with a second light-emitting band of 800nm to 850nm, and the light beam with the second light-emitting band has a higher reflectance at the real skin. By using the first and second light sources, the real prosthesis can be better distinguished.
In the embodiment of the application, the terminal combines the actual requirements on the light source and the determination method of the spectral data, which is passed by the embodiment of the application, so that the spectral dimension information can be improved to the maximum extent in the algorithm, the spectral resolution is increased, and the accuracy and robustness of the algorithm can be effectively increased when the obtained target spectral data is applied to the live examination.
