First, some terms or terms appearing in the description of the embodiments of the present application are applicable to the following explanations:
Tomo-PIV: the Tomographic particle Image Velocimetry (Tomographic partial Image Velocimetry) is a three-dimensional particle Image Velocimetry technology generated by combining a PIV technology and a medical CT (computed Tomography) reconstruction technology, and can realize full-field quantitative measurement of a spatial flow field.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of an object processing method, it should be noted that the steps illustrated in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is an object processing method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, releasing predetermined particles to a target measurement area of a target object, wherein the target measurement area is plated with an antireflection film;
step S104, irradiating pulse laser with preset energy to preset particles in a target measurement area;
step S106, a predetermined camera is adopted to photograph the predetermined particles irradiated with the pulse laser according to a predetermined frequency, and a plurality of image data are obtained.
Through the steps, the preset particles are released to the target measurement area coated with the antireflection film, the pulse laser with preset energy is irradiated, the preset particles irradiated with the pulse laser are photographed by the preset camera according to the preset frequency, and therefore a plurality of image data are obtained.
As an alternative embodiment, predetermined particles are released to a target measurement region of a target object, wherein the target measurement region is coated with an antireflection film. The anti-reflection film is plated in the target measurement area, so that stray light is eliminated, reflection on the surface of the target measurement area is reduced, the intensity of transmitted light is increased, the reflection phenomenon which can occur after laser irradiation when the target measurement area is shot is inhibited, and imaging is clearer. The method comprises the steps of releasing predetermined particles to a target measurement area of a target object, firstly placing the target object or the target measurement area of the target object in a specified environment, such as a flow field, then releasing a certain concentration of the predetermined particles, and performing a predetermined operation, such as a speed measurement operation on the predetermined particles in a fluid. Alternatively, different concentrations of the predetermined particles may be released in other environments to perform different purpose operations on the predetermined particles.
It should be noted that the target object may be an object with various shapes, for example, may be a two-dimensional plane, a three-dimensional cube, or a three-dimensional curved surface, and a specific model may be set for operation according to the requirements of practical applications, for example, a three-dimensional curved surface model may be set according to the requirements of experiments or tests to perform a predetermined task. It should be further noted that the target measurement area is a partial area of the target object that needs to be measured, that is, the entire target object does not need to be observed, and a partial area of the target object can be selected for operation according to application requirements, so that measurement of the partial area of the target object can be realized, and measurement can be performed as required, which not only saves computer resources, but also can obtain required image data in a targeted manner.
As an alternative embodiment, the predetermined particles are encapsulated by a fluorescent substance. By wrapping the predetermined particles with the fluorescent substance, the purpose of identifying the positions of the predetermined particles in a key manner is achieved, and a clearer image of the fluorescent particles can be seen. The degree of the predetermined particles wrapped by the fluorescent substance is adjustable, and the predetermined particles can be adjusted by combining the filter and the pulse laser with predetermined energy comprehensively so as to achieve a better identification effect.
As an alternative embodiment, a pulsed laser with a predetermined energy is irradiated to the predetermined particles in the target measurement region, wherein the pulsed laser with a high energy may be selected to irradiate the predetermined particles in the target measurement region via the bulk light source, so that the predetermined particles can generate a fluorescence signal with a certain fluorescence wavelength under the irradiation of the pulsed laser with a high energy via the bulk light source. The pulse laser with proper preset energy is selected to irradiate the preset particles in the target measurement area, so that the image data obtained by shooting can better accord with the expected effect.
As an alternative embodiment, a predetermined particle irradiated with the pulsed laser is photographed by a predetermined camera according to a predetermined frequency to obtain a plurality of image data. The preset frequency according to the preset camera is adapted to the frequency of the pulse laser, namely when the pulse laser irradiates at the preset frequency, the preset camera shoots at the same frequency, the positions of the preset particles at different times are recorded, and the motion trail of the preset particles is obtained through the image data obtained by shooting. When the predetermined camera performs shooting, the predetermined camera may be set to be photosensitive shooting, or the shooting frequency of the predetermined camera may be set to be the same as the irradiation frequency of the pulsed laser, and so on, and various manners may be adopted. It should be noted that the number of the predetermined cameras may be plural. Furthermore, the image data may include a variety of information, and different information may be adaptively obtained according to different purposes, for example, when a velocity field of a predetermined particle in the flow field is measured, the image data may include a distribution of pixel gray levels in the image, and the like. The preset particles irradiated with the pulse laser are photographed by adopting the preset camera according to the preset frequency, so that a plurality of clear image data which effectively suppresses reflected light can be obtained, and better processing can be performed.
As an alternative embodiment, a predetermined particle irradiated with the pulse laser is photographed by a predetermined frequency using a predetermined camera having a filter mounted in front thereof, and a plurality of image data are obtained. In front of the predetermined camera, a filter is disposed, which can be variously set according to the requirements of the actual application, for example, setting of a filtering wavelength, setting of a filtering color, and the like. In a preset particle speed measurement scene, the purpose of filtering out reflection caused by the fact that the pulse laser irradiates a wall surface without influencing the passing of a fluorescence signal can be achieved.
As an alternative embodiment, before photographing the predetermined particles irradiated with the pulse laser according to a predetermined frequency by using a predetermined camera with a filter mounted in front thereof, obtaining a plurality of image data, the method further comprises: collecting fluorescent signals generated after the particles wrapped by the fluorescent substance are irradiated by the pulse laser; acquiring the laser wavelength of the pulse laser and the fluorescence wavelength of the fluorescence signal; the cut-off wavelength and the cut-off width of the filter are determined according to the laser wavelength and the fluorescence wavelength. Fluorescent signals with different fluorescent wavelengths can be generated according to different illumination intensities irradiated by the pulse laser. Therefore, it is necessary to collect a fluorescence signal having a predetermined fluorescence wavelength generated after the particles encapsulated by the fluorescent substance are irradiated with the pulsed laser. So that the cut-off wavelength and the cut-off width of the filter are determined according to the fluorescence wavelength and the laser wavelength. The cut-off wavelength and the cut-off width of the filter are set according to the pulse laser and the preset particles, reflection caused by the fact that the pulse laser irradiates the wall surface is filtered, and the filter can be guaranteed to carry out filtering operation in a targeted mode through the fluorescent signals. Alternatively, the cutoff wavelength and the cutoff width of the filter are determined depending on the laser wavelength and the fluorescence wavelength, and may be set in the following manner: determining the cutoff wavelength as the average value of the laser wavelength and the fluorescence wavelength; the cutoff width is determined to be a value smaller than the difference between the laser wavelength and the fluorescence wavelength. Through the numerical relation setting of the laser wavelength, the fluorescence wavelength, the cut-off wavelength and the cut-off width, the filter can more accurately filter stray light.
As an alternative embodiment, after photographing the predetermined particles irradiated with the pulsed laser according to a predetermined frequency by using a predetermined camera to obtain a plurality of image data, the method further includes: determining a displacement of the predetermined particle from the plurality of image data; determining the time corresponding to the displacement according to the preset frequency; from the displacement and the time, the velocity of the predetermined particle is determined. When the obtained plurality of image data are used for calculating the velocity field of the predetermined particles, the distribution of the predetermined particles is recorded, the position information of the predetermined particles at a certain time point can be obtained, the displacement information of the predetermined particles in a certain time period can be obtained, the time period can be counted by a predetermined frequency, so that the velocity of the predetermined particles is determined, and the velocity field of the predetermined particles in the target measurement area is obtained.
Based on the above embodiments and alternative embodiments, an alternative implementation is provided, which is described in detail below.
In the related technology, when a conventional Tomo-PIV is used for measuring a three-dimensional curved surface near-wall flow field, light reflection interference formed by a light source irradiating a curved surface can cover optical signal information of a particle image of the flow field, so that the speed measurement of ions cannot be performed.
In view of the above, in an alternative embodiment of the present invention, a solution for measuring velocity of a near-wall particle image fluid is provided, in which particles doped with a fluorescent substance are scattered into a target measurement area, and a pulsed laser with a predetermined excitation frequency is used to excite the particles to fluoresce; the filtering technology is adopted to filter the reflected laser light and transmit the particle fluorescence signal, so that the interference of the wall surface reflection light on the particle image can be eliminated, and a clear particle image can be obtained.

And S5, performing speed measurement detection according to the fluorescent particle images shot for the target measurement area to obtain a speed detection result.
It should be noted that the speed measurement mode is as follows: meanwhile, a plurality of (generally 3-6) cameras are used for recording particle moving images, then iterative Reconstruction is carried out on the particle distribution in the three-dimensional space by using a Multiplicative Algebraic Reconstruction algorithm (MART) according to the distribution of pixel gray levels in a picture, three-dimensional cross-correlation calculation is carried out on 2 reconstructed adjacent particle images to obtain the displacement information of the particles, and then a speed detection result is obtained according to the exposure time.
