Detailed ways

In order to make the objects, technical solutions, and advantages of the present application more comprehensible, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Embodiment 1

Referring to FIG. 1 , a method for querying property information in this embodiment includes the following steps:

In step 01, the identity information of the identity card is collected.

The information of the second-generation ID card placed by the user is collected by the ID card information collector, including but not limited to the ID card number, expiration date, and photo. The ID card number is used to match and query the information in the database of the housing management department. The photo is used for face recognition verification. Preferably, the user ID is identified by the ID card number, such as gender, age, region, etc., so that the camera angle and the shooting parameters are adjusted in the subsequent face recognition verification process, so that users with different features can be photographed to meet the verification requirements. Reduce the rate of misunderstanding and increase the pass rate.

In a preferred embodiment, the identity information photo is a photo of the ID card reserved in the public security system, and the subsequent step 05 further includes descreening the photo before the face feature similarity comparison to improve the recognition effect. . In addition, the identity photo may also be a verified photo reserved in the housing management department or other agency departments, third-party agencies.

In step 02, it is determined whether the ID card is valid. If yes, step 03 is performed, otherwise the prompt is invalid.

Among them, the collected ID card information is compared with the information in the database of the housing management department or the database of the public security department to determine whether the ID card is valid and whether it is still within the validity period. If it is judged to be invalid or exceeds the validity period, the direct feedback is invalid or expired. Prompt, do not follow the next steps or prompts to go to the manual counter; if it is judged to be valid, then perform step 03, this step can improve the efficiency of the query, eliminating the need to spend more time on the authentication and ultimately due to the ID card expired Causes no query. In the actual application, after the valid period of the ID card is collected in step 01, it is directly determined whether the ID card is within the validity period according to the date of the system.

In step 03, it is determined whether the person corresponding to the identity information has a room, and if yes, step 04 is performed, if otherwise, no room is prompted.

Querying whether the user has a room in the database of the housing management department according to the identity information, preferably according to the unique ID number, if there is no room, directly feedback no room prompt or directly print the no-room certificate file, and no subsequent steps are performed; If there is a room, go to step 04.

In step 04, it is suggested whether the person corresponding to the identity information is inquiring, and if the feedback is obtained by himself, step 05 is performed, otherwise the user is prompted to go to the manual counter.

In order to improve security and privacy, and to prevent the use of other people's ID cards to inquire about housing information, this step first asks whether to handle it for the person by asking questions. If not, directly print the receipt to prompt the user to go to the manual counter. Wherein, the receipt has a feature code matching the ID card information collected in step 01, such as a barcode or a two-dimensional code, so as to facilitate subsequent manual scanning of the manual counter. Among them, this step can save the time of the whole query, because if face recognition is performed directly, especially if there are multiple failed retry steps, the situation that is not handled by the person will cause a lot of time, so first prompt whether to handle it for yourself. If the options "I am yourself" and "others agent" are provided, the latter can directly print the receipt without clicking on the face recognition verification step, saving time and improving efficiency.

In a preferred embodiment, if the determination in the step is negative, the method includes printing a receipt and prompting to go to the manual counter, and the receipt has a signature matching the identity information.

In step 05, the camera is turned on and the face recognition verification is performed. If the verification is passed, step 06 is performed, and if the verification is not passed, the user is prompted to go to the manual counter.

Evaluating the photographing quality may include a head angle evaluation, a brightness evaluation, and a motion blur evaluation, and the head angle evaluation includes determining whether the head is up and down, for example, within 15 degrees, the left and right declination is within, for example, 15 degrees, and the rotational declination is, for example, Within 20°, if it is consistent, it is considered to meet the head angle evaluation; the brightness evaluation includes determining whether the brightness is within, for example, [80,200], if it is met, it is considered to meet the brightness evaluation; the dynamic fuzzy evaluation includes determining whether the fuzzy value is, for example, Less than 0.2, if it is met, it is considered to be in compliance with the dynamic fuzzy assessment. If the shooting quality evaluation does not meet the requirements, the user will be prompted to adjust the content, such as "Please position the head", "Please slightly lower head", "Please slightly away from the camera", if the brightness evaluation does not meet the requirements, you can also pass the camera Adjust the flash set next to it. In addition, evaluating the quality of the shot may also include determining whether the user wears thick-rimmed glasses, sunglasses, or whether the hair blocks the ears or other facial features.

Wherein, the face feature locating step preferably includes locating features of the face including a plurality of organs such as eyebrows, eyes, nose, mouth, and the like. The face feature extraction step preferably includes extracting a plurality of feature information for each feature according to a preset extraction rule. The face feature similarity comparison step preferably includes comparing the extracted plurality of feature information with the feature information of the pre-stored user photo one by one, and if the obtained similarity is higher than a preset threshold, determining that the face recognition verification is passed If you are prompted to try again, you can have up to three times. The face feature may include parameters such as length, slope, and gray scale to represent the three-dimensional size, the tilt direction, and the distance from other parts of the part, and the face feature may be a set of feature information. The facial feature similarity comparison may be to compare the two sets of feature information one by one, and define each feature information to have a certain weight, for example, the weight of the important feature information, and the weight of the secondary feature information is relatively small, and may also be defined. Some feature information is a necessary condition for judging that it must be consistent.

In a preferred embodiment, after the screenshot of the face image, a biometric face step is further included, that is, it is used to determine whether the user himself or herself is photographed instead of using another person's photo for remake, thereby improving security. The physical examination face specifically includes the face feature positioning and the head angle positioning, and prompts to complete the specified action as required, such as opening the mouth, moving the headlight, determining whether the face feature or the head angle completes the specified action, and if so, passing the living body face detection, the performer The identification verification step after face acquisition.

In a preferred embodiment, after the photo of the ID card is obtained, the photo (ie, the photo of the ID card in the public security system) is detextured to improve the recognition effect.

In a preferred embodiment, the step of adjusting the camera angle and the shooting parameters according to the user information such as age, gender, and region in the identity information before the face collecting step is performed, so as to facilitate shooting of users with different features. Verify the required photos, reduce the false positive rate and increase the pass rate. For example, according to the user information for the southern city, the elderly, and the female, it is more likely that the user's height will not be too high, then the camera angle may be slightly adjusted downward; and if the user information is African-American, the user's skin color is predicted. If it is more likely to be darker, you can turn on the flash or slightly adjust the brightness.

In a preferred embodiment, if the step is not verified, the method includes printing a receipt and prompting to go to the manual counter, the receipt having a signature matching the identity information.

Step 06, print the property information certificate.
