detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a liquid property detecting method and system. The first target image is obtained by scanning the liquid to be tested, and the formed information of the first target image is obtained, and then it is determined whether the formed information meets the preset. The condition, if yes, determining that the liquid to be tested is a positive liquid, and if the liquid to be tested is determined to be a negative liquid, the implementation process of the present invention is performed by the image scanning device and the server, and the image processing and the calculation process are used to detect the test. Whether the liquid is formed or not, avoids the influence of interference factors in the dry chemical test method, and improves the reliability and accuracy of the test. Referring to FIG. 1, a flow chart of Embodiment 1 of a liquid property detecting method according to the present invention is shown. The method can include the following steps:

Step 101: Scan the liquid to be tested to obtain a first target image.

This embodiment is for detecting the formed component in the liquid to be tested, and the forming component is a visible component which is insoluble in the liquid, for example, in the medical field for urine detection, red blood cells, white blood cells, and other cell tubes in the urine. Types and the like are all formed. Of course, the present invention is also used for liquid detection in other fields. For example, in the field of beverage production, a component is a substance in a liquid.

When the formation of the liquid to be tested is detected, the liquid to be tested is flushed into the detection tank, and the detection tank is a container for filling the liquid, and the liquid intake amount of the liquid in the detection tank is controlled by the system. In this embodiment, the preset scanning capacity of the liquid to be tested may be set. When the system detects that the liquid content of the flushing detection pool is equal to the preset scanning capacity, and waits for the liquid to stand for a period of time, the scanning device is started to scan. The first target image is obtained, and when there is a formation point in the liquid, it can be displayed in the first target image obtained by scanning.

Wherein, when the liquid to be tested is scanned, the scanning may be performed according to the first preset scanning parameter, and the quantity is set. The scanning parameters include the scanning field of view, the scanning distance and the scanning route. The specific setting process can be as follows:

First, the preset scan capacity of the liquid to be tested is determined.

Since the formed component in the liquid to be tested may contain a plurality of species, for example, urine, including red blood cells, white blood cells, tubular type, etc., and different types of formed components, the sensitivity required for detection is different, and it is required to be based on the liquid to be tested. The formation type is set to determine the liquid detection sensitivity, and in order to avoid the occurrence of the miss detection, the valley of the liquid to be tested is determined according to a type of formed component having a high detection sensitivity in the formation.

There are three types of formed components in the liquid to be tested, which are steroids, B, and C. For example, the sensitivity of the type A component is less than 1/UL (microliter), that is, every 1 UL exists. One has a forming component, the sensitivity of the B-type component is required to be 1/10UL, and the sensitivity of the C-type component is 1/100UL. It can be known that the detection sensitivity of the C-class is the highest, and the liquid to be tested is known. The capacity is at least 100UL. Therefore, it is possible to set a certain value that the preset scan capacity is equal to or greater than 100UL.

After determining the preset scan capacity of the liquid to be tested, the scan parameter can be determined according to the preset scan capacity. In combination with the volume of the detection pool, the determination of the amount of scanning field of view is specifically as follows: Let the thickness of the detection pool container be H, and the field of view area when scanning is S, then the apparent field of view volume in one field of view is SH, according to the calculation The volume of the liquid to be scanned is L, in order to ensure no missing detection, the amount of scanning field of view should be at least: L/SH.

The scan path may be determined as follows: If the width of the field of view when scanning is D, the cross-sectional area of the scan is DH. According to the determined liquid volume to be scanned, the scan path should be at least: L/DH.

Among them, the scanning route can select different routes according to different situations. For example, when scanning a microscope, a bow-shaped scanning route can be adopted.

In practical applications, the embodiment is specifically applied in a fully automatic microscope camera system, and the system controls the liquid volume of the detection pool. When the liquid volume in the detection pool reaches a preset scanning capacity, the microscope is started to scan, and the above-mentioned determined scanning field quantity is determined. This is the amount of scanning field of view of the microscope objective. When the distance of the scan is large and beyond the scope of the detection pool, the scan can be scanned back and forth to ensure that the scan completes the required route. The system can use the motion microscope to perform three-dimensional scanning in the XYZ direction of the liquid to be tested. The required scanning field of view cannot overlap. Of course, it is also possible to fix the microscope and control the detection pool. In order to increase the detection speed, the magnification can be determined according to different detection sensitivities and the size of the formed fraction. Since only the liquid to be tested or the total content of the formed components in the liquid is obtained, the microscope can be scanned at a low magnification.

Step 102: Acquire the formed information of the first target image.

The formed component information in this embodiment includes a component content.

When the liquid to be tested is scanned in step 101, since the image is scanned according to the scanning route, the image is continuously acquired, and one frame of image is obtained in each scanning field, so that the formed information is currently obtained. The formed target information in the first target image includes the content of the formed component, which may further include the positional information of the formed component. The location information refers to the location in the first target image obtained by the forming points under different scanning routes. The process of acquiring the image data may be specifically implemented by using an image recognition function.

Step 103: Determine whether the formed component information satisfies a preset condition, and if yes, proceed to step 104, and if no, proceed to step 105.

In this embodiment, the preset condition is that the formed component content is greater than a preset value. The preset value is a value set according to different actual conditions. In medical urine detection, the preset value is set according to a medically prescribed standard value, and the standard value may not be in different regions. Similarly, it needs to be specifically set according to the actual application environment. For example, the standard value of the formed content of red blood cells in urine is A per microliter, and the sensitivity of red blood cells to be detected in urine is the highest. The value is the product of the standard value of the red blood cell and the preset scan capacity. Above this preset value, urine is considered positive urine and there may be abnormalities. Of course, when the present invention is applied to other fields of detection, such as the field of beverage detection, the preset value is set according to the standard value of the impurity content in the beverage.

Step 104: Determine that the liquid is a positive liquid.

Step 105: Determine that the liquid is a negative liquid.

When the forming sub-information meets the preset condition, that is, if the forming component content is greater than the preset value, the system determines that it is a positive liquid, and simultaneously prompts the user, and when the predetermined condition is not satisfied, the forming component content is less than or equal to the pre-predetermined condition. If the value is set, the system determines that the liquid is a negative liquid and prompts the user to display the prompt information on the display interface of the system, or can sound an alarm sound, so that the user can judge whether to end the detection process.

In this embodiment, the formed component information is obtained by scanning the liquid to be tested, and whether the predetermined condition is satisfied according to the formed component information, and if yes, determining that the liquid is a positive liquid, and if not, determining the liquid For the negative liquid, the image is scanned by the system, and the data is calculated by the system, thereby avoiding the influence of interference factors and improving the reliability and accuracy of the detection. Referring to Fig. 2, there is shown a flow chart of Embodiment 2 of a liquid property detecting method of the present invention, which may include the following steps:

Step 201: Perform a blank scan to obtain a blank image, and acquire blank data of the blank image.

The blank data includes the device stain content.

The device used to scan the liquid to be tested in the system may be stained. For example, when the scanning device is a microscope, the objective lens or eyepiece of the microscope may have stains, and the stain will be displayed in the image, because only the low-magnification scan is used, and the image is If the stain and the formed component of the device cannot be distinguished, the measurement result may be inaccurate. Therefore, in this embodiment, before scanning the liquid to be tested, a blank scan is first performed, that is, when the detection pool is not filled with any liquid, the scan is performed. A blank image is obtained. If the device has a stain, the particles displayed on the blank image are stains of the device. Therefore, blank data can be obtained according to the blank image, and the blank data includes the stain content of the device, and may also include The device smears the location information in the image.

Step 202: Scan the liquid to be tested according to the first preset scanning parameter to obtain a first target image.

For the setting of the first preset scanning parameter, refer to the method embodiment 1, which is not described here. Before scanning the liquid to be tested, it is also possible to first detect whether the capacity of the liquid to be tested is equal to the preset scanning. Capacity, if yes, perform the operation of step 202.

Step 203: Acquire the formed component information of the first target image, where the formed component information includes a component content.

Due to the presence of the stain of the device, in the first target image acquired when scanning the liquid to be tested, the solid particles in the image include not only the formed component, but also the device stain, and therefore, the acquired formed information is the liquid to be tested. There is a total content of formation and equipment stains.

Step 204: Determine whether the difference between the formed component of the liquid to be tested and the total content of the stain of the device and the stain content of the device is greater than a preset value, and if yes, proceed to step 205, and if no, proceed to step 206.

Calculating the difference between the total content of the formed component information and the stain content of the device according to the stain content of the device obtained during the blank scan, and determining whether the difference is greater than a preset value, and if so, indicating that the content of the liquid is greater than the pre-formation If the value is set, the process proceeds to step 205. If no, it indicates that the formed content in the liquid is less than or equal to the preset value, and then proceeds to step 206.

And determining whether the difference between the total content and the stain content of the device is greater than a preset value, or first, calculating a sum of the stain content of the device and a preset value, and then determining whether the total content is greater than the And the value, if it is, indicates that the content of the component in the liquid is greater than a preset value, and if not, it indicates that the content of the component in the liquid is less than or equal to a preset value.

Step 205: Determine that the liquid is a positive liquid, and proceed to step 207.

When it is determined that the content of the formed component is greater than the preset value, it indicates that the liquid to be tested is a positive liquid, and the user may be prompted to perform the operation of step 207 on the system display interface.

When the liquid to be tested is scanned, the obtained first target image is the current first target image, and the formed target information is the current target data, and the current target data is the sum of the data in each acquired image, when it is determined When the target data meets the preset condition, the current scan can be stopped, that is, in the case that the scanning field of view and the scanning path are not completed, the current information can be terminated as long as it is determined that the current forming information meets the preset condition. Scan Step 206: Determine that the liquid is a negative liquid.

When it is judged that the content of the formed component is less than or equal to the preset value, it indicates that the liquid to be tested is a negative liquid, and is presented to the user on the system display interface, then the system can end the detection process.

Step 207: Continue scanning the liquid to be tested according to the second preset scanning parameter to obtain a second target image.

When it is judged that the liquid to be tested is a positive liquid, if there is a formation exceeding the standard, indicating that the liquid to be tested is abnormal, the type of the formed component in the liquid to be tested may be further detected.

The liquid to be tested continues to be left for a period of time, and then the scanning device is controlled to continue scanning the liquid to be tested according to the second preset scanning scan to obtain a second target image.

The second preset scan parameter includes a scan view amount, a scan path, and a scan route. Step 208: Acquire target information of the second target image, where the target information includes different types of formed content and location information.

Step 209: Perform morphological detection on the formed component by using a machine vision recognition method according to the target information.

In the field of medical testing, the existing machine vision recognition method can automatically realize the morphological data analysis of the formed components, and can classify and count various types of formed components, and can obtain the size and shape of each type of formed component. Or information such as color, so that it can be known which type of liquid has a problem.

The machine vision recognition method is based on the morphological analysis method of the fully automatic microscope camera system. The system pre-trains various types of models with formed points. Therefore, based on the acquired target information, it is compared with various types of formed data models in the system simulation database. Yes, the morphological examination of the formed fractions can be automatically realized without the need for manual microscopic examination.

In this embodiment, after detecting that the liquid to be tested is a positive liquid, the morphological detection is continued, and the liquid to be tested is a negative liquid, that is, when the liquid is normal, the process is directly ended, and no morphological detection is required, thereby avoiding no The necessary testing improves the detection efficiency while saving equipment resources.

Of course, after detecting that the liquid to be tested is a positive liquid, the method can also adopt other methods for morphological detection, and further classify and count the formed components. In this embodiment, before the liquid to be tested is scanned, a blank scan is first performed to obtain an empty The blank data of the white image, that is, the stain content of the device, when the liquid to be tested is scanned, the target data is acquired, and the difference between the total particle content in the acquired target data and the stain content of the device is calculated, and the difference is the liquid Forming a sub-content, determining whether the difference is greater than a preset value, and if so, the liquid to be tested is a positive liquid, continuing to scan, performing morphological analysis using a machine vision recognition method, and if not, the liquid to be tested If it is a negative liquid, the test process can be ended. It avoids the interference of external factors, and also avoids the interference caused by the formation of liquid in the device itself, improves the detection accuracy, and at the same time, can continue the morphological detection of the liquid with positive liquid to be tested, and further analyze the formation. kind.

The invention can be applied to the morphological detection, and the negative liquid can be screened out, the negative liquid is not detected, and the positive liquid is continuously subjected to morphological detection, thereby avoiding unnecessary detection and providing the efficiency of morphological detection. Referring to FIG. 3, a flow chart of Embodiment 3 of a liquid property detecting method according to the present invention is shown, and the method may include the following steps:

Step 301: Scan a liquid having a known component content to obtain a first image, and acquire first image data of the first image.

Wherein the first image data comprises a solid particle content.

The device used to scan the liquid to be tested in the system may have stains. For example, when the scanning device is a microscope, the objective lens or the eyepiece may be stained, which may result in inaccurate measurement results. Therefore, in this embodiment, the liquid to be tested is scanned. Previously, a liquid having a known component content is first scanned, a first image is obtained, and the first image data is acquired according to the first image. Since the scanning device itself has a stain, the known liquid will be displayed in the first image. There is a component and a device stain, and the solid particle content of the first image data is the total number of formed components of the known liquid and the stain of the device.

When scanning, especially using a microscope, if the blank is scanned and the test cell is not filled with liquid, the scanned image is blurred. Therefore, in order to obtain the stain content of the device more accurately, the formed content can be detected first. The liquid, the first image obtained will show the device stain and the formed component of the liquid.

Step 302: Subtracting the solid particle content from the formed content of the known liquid, Calculate the stain content of the equipment.

The first image data includes the total content of the formed component of the known liquid and the stain of the device, and the total content is subtracted from the known content of the formed component, that is, the content of the stain of the device.

In this embodiment, in order to reduce the amount of calculation, the liquid having a known component content may be selected from a transparent liquid having a content of zero, so that the solid particle content in the obtained first image data is the stain content of the device. .

Step 303: Scan the liquid to be tested according to the first preset scanning parameter to obtain a first target image. Step 304: Acquire the formed component information of the first target image, where the formed component information includes a total content of the liquid to be formed and the stain of the device.

Step 305: It is determined whether the difference between the total content of the liquid to be measured and the stain of the device and the calculated stain content of the device is greater than a preset value, and if yes, proceed to step 306, and if no, proceed to step 307. .

Calculating a difference between the total content in the formed component information and the stain content of the device, determining whether the difference is greater than a preset value, and if yes, indicating that the formed content in the liquid is greater than a preset value, proceeding to step 306, If not, it indicates that the formed content in the liquid is less than or equal to the preset value, and the process proceeds to step 307.

Wherein, it is determined whether the difference between the total content of the formed component and the stain of the device and the stain content of the device is greater than a preset value, or it may be, first, calculating the sum of the stain content and the preset value of the device The value is then judged whether the total content is greater than the sum value, and if so, it indicates that the content of the component in the liquid is greater than a preset value, and if not, it indicates that the content of the component in the liquid is less than or equal to a preset value.

Step 306: Determine that the liquid is a positive liquid, and proceed to step 308.

Step 307: Determine that the liquid is a negative liquid.

Step 308: Continue scanning the liquid to be tested according to the second preset scanning parameter to obtain a second target image.

When it is judged that the liquid to be tested is a positive liquid, there is a formation exceeding the standard, indicating that the liquid to be tested is abnormal, and the type of the formed component in the liquid to be tested may be further analyzed.

The liquid to be tested is allowed to stand for a certain period of time, and the liquid to be tested is scanned according to the second preset scan number to obtain a second target image.

The second preset scan parameter includes a scan view amount, a scan path, and a scan route. Step 309: Acquire target information of the second target image.

The target information may include different types of formed content and location information. Step 310: Perform morphological detection on the formed component by using a machine vision recognition method according to the target information.

In this embodiment, before the liquid to be tested is scanned, the liquid having the known component content is selected for scanning, the stain content of the device is calculated, the liquid to be tested is scanned, and the total content in the target data and the stain content are obtained. Comparing with the preset value, determining whether the formed component content of the liquid to be tested is greater than a preset value, thereby determining the positiveness of the liquid to be tested, improving the accuracy of the liquid detection, and when the liquid to be tested is a positive liquid, performing further The morphological detection classifies and counts the formed components in the positive liquid, thereby improving the efficiency of morphological detection and avoiding unnecessary detection. Referring to FIG. 4, a structural diagram of Embodiment 1 of a liquid property detecting system of the present invention is shown, and the system may include:

The image scanning device 401 scans the liquid to be tested to obtain a first target image.

a server 402 connected to the image scanning device 401, the server 402 receives the first target image transmitted by the image scanning device, acquires the formed component information of the first target image, and determines whether the formed component information is satisfied. The predetermined condition, if yes, determines that the liquid is a positive liquid, and if not, determines that the liquid is a negative liquid.

When the liquid to be tested is tested, the liquid to be tested is first flushed into the detection tank, and the detection pool is a container for filling the liquid, and the detection pool is connected to the detection system, and the liquid intake amount of the liquid in the detection pool can be controlled by the system. Preferably, the system can set a preset scan capacity of the liquid to be tested. When it is detected that the liquid content of the flushing detection pool is equal to the preset scan capacity, the image scanning device 401 is activated to scan to obtain the first target image. When there is a forming point in the liquid, it can be displayed in the scanned first target image, and then the first target image is transmitted to the server 402. The image scanning device 401 may be specifically a microscope, and the server 402 It can be a computer, or an integrated image processing system.

The image scanning description device 401 performs scanning according to a first preset scanning parameter, where the first preset scanning parameter is performed according to a preset scanning capacity determined according to the detection sensitivity of the liquid to be tested. Set. The scanning parameters include the scanning field of view, the scanning distance and the scanning route. The specific setting process can be as follows:

First, the preset scan capacity of the liquid to be tested is determined.

Since the formed component in the liquid to be tested may contain a plurality of species, for example, urine including red blood cells, white blood cells, cell tube type and the like, and different types of formed components, the sensitivity required for detection is different, and it is required according to the liquid to be tested. Forming the classification type to set the detection sensitivity, in order to avoid causing the missed detection, specifically, the capacity of the liquid to be tested is determined according to the type of formed component having a high detection sensitivity in the formation.

There are three types of formed components in the liquid to be tested, which are classified into Class A, Class B, and Class C. The sensitivity for the detection of Class A formation is less than 1/UL (microliter), that is, every 1 UL exists. One has a forming component, the sensitivity of the B-type component is required to be 1/10UL, and the sensitivity of the C-type component is 1/100UL. It can be known that the detection sensitivity of the C-class is the highest, and the liquid to be tested is known. The capacity is at least 100UL. Therefore, it is possible to set a certain value that the preset scan capacity is equal to or greater than 100UL.

After determining the preset scan capacity of the liquid to be tested, the scan parameters can be determined according to the preset scan capacity.

Combined with the volume of the detection pool, the amount of scanning field of view is determined as follows: Let the thickness of the detection pool container be H, and the field of view area when scanning is S, then the apparent field of view volume in one field of view is SH, according to the calculated The preset scanning capacity L of the liquid to be tested, in order to ensure no missing detection, the scanning field of view should be at least: L/SH.

The determination of the scan path may be: The width of the field of view when scanning is D, and the cross-sectional area of the scan is DH. According to the determined scan capacity of the liquid to be tested, the scan path should be at least: L/DH.

In practical applications, the server controls the liquid capacity of the detection pool. When the liquid capacity in the detection pool reaches the preset scanning capacity, the image scanning device is started to perform scanning, and the above-mentioned determined scanning field quantity is the scanning field quantity of the microscope objective lens. When the scanned distance is larger and exceeds the range of the detection pool, Scanning back and forth can be used to ensure that the scan completes the required route. The motion microscope can be used to perform three-dimensional scanning in the XYZ direction of the liquid to be measured, and the required scanning field of view cannot be overlapped. Of course, the microscope can be fixed and the detection pool can be controlled to scan. In order to increase the detection speed, the magnification may be determined according to different detection sensitivities and the size of the formed fraction. Since the content of the formed liquid or the formed component in the liquid is obtained by scanning, the microscope may be scanned at a low magnification.

When a component is formed in the liquid, it can be displayed in the first target image obtained by scanning. When scanning the liquid to be tested, the image scanning device scans according to the scanning route, so the image is continuously acquired, and one frame of image is obtained in each scanning field of view, so the formed minute information is currently obtained by the server. The sum of the data in each frame of the image. In this embodiment, the formed component information includes a content of the formed component, and may further include location information of the formed component. The position information refers to a position in the first target image obtained by the forming points under different scanning routes. The process of acquiring the image data may be specifically implemented by using an image recognition function.

The server determines whether the formed component information satisfies a preset condition, and the preset condition may specifically mean that the formed component content is greater than a preset value. The standard value may be different in different regions, and needs to be set according to the actual application environment. For example, the standard value of the formed content of red blood cells in urine is A per microliter, and the red blood cells are required to be detected in urine. The sensitivity is the highest, and the preset value is the product of the standard value of the red blood cell and the preset scan capacity. Above this standard value, urine is considered positive urine and there may be lesions. Of course, when the present invention is applied to other fields of detection, such as the field of beverage detection, the preset value means that the content of impurities in the beverage meets the prescribed standard value.

When the forming sub-information meets the preset condition, that is, if the forming component content is greater than the preset value, the server determines that the liquid to be tested is a positive liquid, and simultaneously prompts the user, and if the predetermined condition is not satisfied, the forming component content is less than or If the value is equal to the preset value, the server determines that the liquid to be tested is a negative liquid, and gives a prompt. For example, the prompt information may be displayed on the display interface of the server, so that the user can judge whether to end the detection process.

In this embodiment, the first target image of the liquid to be tested is obtained by scanning the liquid to be tested by the image scanning device, and the image processing is performed by the server to obtain the formed information of the first target image, and the measured information is determined according to the formed information. Whether the liquid is a positive liquid or a negative liquid, the detection process is automatically completed by the system without manual intervention, which avoids the influence of interference factors in dry chemical analysis, thereby improving the accuracy of the detection.
