When fusion processing is performed on multi-source research data, preprocessing, especially data verification, is required for the data. In the present embodiment, at least one candidate data of the research object is acquired. And performing first verification on target candidate data in the candidate data, wherein the first verification comprises verifying the target candidate data according to the attribute value of the target candidate data. Specifically, when the target candidate data is the attribute of the investigation object, judging whether the data value of the candidate data exceeds a preset interval; when the data value of the candidate data does not exceed a preset interval, determining that the first verification of the target candidate data is passed; and when the data value of the candidate data exceeds a preset interval, determining that the first verification of the target candidate data is failed. When the first verification passes, performing second verification on the target candidate data according to at least one candidate data; when the second verification is performed, the person image verification is performed first to ensure that the collected data is data corresponding to the investigation subject himself. Specifically, a face image of a research object is extracted from video data; comparing and verifying the facial image with data in the accurate poverty alleviation large data platform data; when the research object information does not exist in the precise poverty-relief big data platform data, reminding that the verification fails and outputting a reminding message for judging whether new research object information data is needed or not; when the verification is passed, respectively performing second verification on candidate data corresponding to the investigation object, for example, when the attribute of the investigation object is the age of the investigation object, acquiring identity card data of the investigation object, wherein the identity card data may be obtained by directly inputting in a system or obtained by extracting image data from an acquired photo; and verifying the authenticity of the age of the investigation object according to the age information recorded in the identity card data of the investigation object. For another example, when the attribute of the research object is the height of the research object, the image data of the research object may be acquired; predicting the height of the investigation object according to the investigation object and the surrounding environment information in the image data of the investigation object to obtain a predicted value of the height of the investigation object; comparing the height of the investigation object with the predicted value of the height of the investigation object; and when the difference value of the comparison result is smaller than a first preset difference value, determining that the second verification is passed. For another example, when the target candidate data is the income value of a research object, acquiring information capable of representing the economic condition of the research object; determining a predicted value of the income of the research object according to the information capable of representing the economic condition of the research object; comparing the predicted value of the income of the research object with the income value of the research object; and when the difference value of the comparison result is smaller than a second preset difference value, determining that the second verification is passed. And when the second verification is passed, determining the target candidate data as the investigation data of the investigation object.
After completing the double verification of each candidate data point, the data is pre-judged in advance according to the poor dimensionality. The multi-source research data is judged from four aspects of family property, family population, health condition and education condition. For example, for family property, firstly, family income is obtained from questionnaire data and is compared with accurate poverty-improving big data platform data, and when the annual average change amplitude of income exceeds a preset threshold value, the research object is determined not to be poverty-improving; and then calculating the annual income change amplitude of the research object, and when the annual income change amplitude of the research object exceeds a preset threshold value, correcting the annual income of the research object by using the local average income level change amplitude as the annual income of the research object. Then, the home assets such as houses and vehicles are analyzed through the video data and the image data. For the house condition, whether a person normally lives or not is judged according to whether a life trace exists or not, for example, whether daily living goods such as tableware, food, clothes and the like exist in the investigated house or not is identified through video images, whether monthly water consumption and electricity consumption conditions are smaller than preset threshold values or not is judged, when the investigated house does not normally live, at least two sets of houses of the investigated house are determined, the conditions of the second set of houses are better than those of the investigated house, and the investigated subject is not poverty. And the safety and value judgment can be carried out through image recognition on the basic appearance of the house, the appearance of the courtyard, economy of whether the courtyard exists or not, such as whether the house has risks of cracking, inclining and collapsing. In addition, the house value can be automatically evaluated by uploading house images, geographical positions and other information by butting a house evaluation system. And for the vehicle condition, the vehicle value is given according to a preset model by identifying the vehicle type and the vehicle application. And finally, predicting the asset condition of the investigation object according to the house value and the vehicle value, and determining that the investigation object is not poverty when the total predicted asset of the investigation object is greater than a preset value. For another example, for family population, the number, age, education condition, occupation condition and the like of family members are firstly obtained from questionnaire data and accurate poverty relief data, the labor population and the fostered population are analyzed, and the poverty of the family is determined through foster expenditure/annual income proportion of the research subject. It should be noted that the family income situation can be further analyzed and judged according to the family labor force situation, for example, if a farmer has no labor force at all and related materials show that the relevant materials have higher work taking income, the data is not true and the reminding processing is required; if a certain farmer indicates that the income is low, and the property and the consumption capacity with higher value are analyzed through the data such as photos, videos and the like of a family house, a living home and the like, the survey data is not real, and the reminding processing is needed. For health conditions and education conditions, information can be further extracted for evidences, medical records and the like through photo data.
After the verification is completed on the data from different sources, the data from different sources can be fused, and according to preset rules, household property scores, labor force scores, medical consumption scores, education support scores, diet support scores, consumption scores and the like are formed.
For the family property score, acquiring the family annual income of a research object from questionnaire data; acquiring a vehicle image and a house image of a research object from the video data, and determining the vehicle condition and the house condition of a research family according to the vehicle image and the house image; and determining the household property score of the investigation object according to the household annual income, the vehicle condition and the house condition of the investigation object.
For the labor force score, determining family members of the investigation object from the questionnaire data, and determining the age, health condition and education level of the family members from the questionnaire data; family member images are obtained from the video data, and family labor force conditions and population burden conditions of the investigation object are determined according to the family member images; and determining the labor force score of the investigation object according to the family labor force condition, the population burden condition and the education level of the investigation object.
For the medical consumption score, determining the medical insurance condition of the investigation object and the family year medical investment data from the questionnaire data; acquiring the number of hospitals with different levels within a preset distance range of a family of the investigation object according to the family position information of the investigation object; and determining the medical consumption score of the research object according to the medical insurance condition of the research object, the family annual medical input data and the number of hospitals with different grades.
For the education guarantee score, determining the number of family educated members of the investigation object, the education level of the family members and the education insurance condition from the questionnaire data; and determining the education guarantee value of the investigation object according to the number of family educated members of the investigation object, the education level of the family members and the education insurance condition.
Extracting a food image and a drinking water image of a research object from the video data for the diet guarantee score; determining the diet condition and the drinking condition of the object to be investigated according to the food image and the drinking image; and determining the diet guarantee score of the research object according to the diet condition and the drinking water condition.
For the consumption value, acquiring the food expenditure, the clothing expenditure, the communication expenditure and the trip expenditure of the investigation object from the investigation data and the accurate poverty-relief big data platform; determining the value of the investigation subject according to the food expenditure, the clothing expenditure, the communication expenditure and the trip expenditure.
It should be noted that, for the above multiple scores, when the scores of the multiple items satisfy different preset thresholds, it indicates that the research object has a condition that needs to be supported on different layers, and gives an early warning prompt to the scores of the research object.
