Detailed Description
The method for generating the image verification code according to the embodiment of the application can be executed by an image verification code generation device, and the device can be independently arranged.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventor of the present application finds in a research process that a person has the ability to identify images with the same depth degree from a plurality of images with the same depth degree, but a machine does not have the ability, and therefore, in the embodiment disclosed in the present application, a user selects a target image verification code that meets the condition in the prompt information from a plurality of candidate image verification codes by taking an original image and an identification image obtained by taking a plurality of objects with different depth degrees, selecting a plurality of candidate areas from the original image or the identification image as the candidate image verification codes, and simultaneously giving the prompt information that at least includes the depth degree condition and selects the target image verification code from the plurality of candidate image verification codes.
When the target image verification code can be identified, the difference between the depth degrees corresponding to the multiple to-be-selected image verification codes needs to be known, so that the process of selecting the target image verification code in the embodiment of the application has higher requirements on the visual function of judging the depth degree of a user, and therefore, the machine has higher difficulty in selecting the target image verification code from the multiple to-be-selected image verification codes, and further, the identification rate of the machine to the target image verification code is reduced.
Referring to fig. 1, a flow chart of an embodiment of a method for verifying an image verification code in the present application is shown, and the embodiment may include the following steps:
step 101: a request for use of a network resource by a user is received.
In this embodiment, before using the network resource, the user needs to send a request for using the network resource to the server, so that the server responds to the request, for example, performing authentication and the like.
Step 102: and displaying the verification information.
And after receiving a request for using the network resource sent by the user, verifying the user so as to ensure that only the user determining the target image verification code uses the network resource. In this embodiment, the verification information may include: the image verification method comprises an original image, an identification image, a plurality of to-be-selected image verification codes and indication information.
Wherein, the original image is: an image obtained by photographing a plurality of objects having different depth degrees, in which the depth degree of an object is reflected by the distance of the object from an image pickup apparatus, generally speaking, the greater the distance of the object from the image pickup apparatus, the greater the depth degree of the object is indicated. Specifically, the depth degree of the object described by each pixel point in the original image is represented by the pixel value in the depth image.
The identification image is an image in which pixel points describing objects with the same depth degree in an original image are marked by the same identification, and pixel points describing objects with different depth degrees are marked by different identifications. The mark may be a symbol mark, a color mark, or the like, for example, the same symbol mark is used for pixel points describing objects with the same depth degree, and different symbol marks are used for pixel points describing objects with different depth degrees. Of course, the identifier may also be represented in other specific forms, and the embodiment does not limit the specific identifier form.
Then, a plurality of candidate areas are determined from any one of the original image or the identification image, and the determined plurality of candidate areas are determined as a plurality of candidate image verification codes, so that a user can select a target image verification code from the plurality of candidate image verification codes. In this embodiment, the verification information includes prompt information required by the user to select the target image verification code, and the prompt information at least includes a depth condition. For example, the user determines the image verification code closest to the user from the multiple candidate image verification codes, and may also sequentially select each candidate image verification code from the multiple candidate image verification codes according to a sequence from far to near or from near to far, and so on. Of course, other depth degree conditions may exist in practical applications, and the present embodiment does not limit the form of the depth degree-containing condition.
It should be noted that, in this embodiment, the conditions required for selecting the target image verification code include a depth degree condition, and in practical applications, the conditions required for specifically selecting the target image verification code may include other conditions, such as a position condition, in addition to the depth degree condition.
For example, the plurality of candidate image verification codes are a plurality of areas selected from the original image, and the user determines the image verification code which is closest to the user and located in a certain coordinate area in the identification image from the plurality of candidate image verification codes.
Step 103: receiving selection information input by a user, and determining an image verification code to be verified corresponding to the selection information.
After the user selects the image verification code to be verified meeting the conditions contained in the prompt message from the displayed verification information, the step receives the selection information containing the image verification code to be verified, and determines the image verification code to be verified corresponding to the selection information from the received selection information.
Step 104: and judging whether the image verification code to be verified meets the condition required by the target image verification code, if so, executing the step 105, otherwise, executing the step 106.
After determining the corresponding image verification code to be verified in the selection information selected by the user, then, judging whether the image verification code to be verified meets the condition required by the target image verification code. Taking an example of selecting the image verification code closest to the user from the multiple image verification codes to be selected in step 102 as an example, in this step, it is required to determine whether the image verification code to be selected is the image verification code closest to the user, that is, whether the image verification code to be selected is the image with the minimum depth degree in the original image.
Step 105: allowing the user to use the network resources.
In this embodiment, the indication information at least includes a depth condition required by the target image verification code, and since the user has a higher requirement on the visual function of the user in the depth degree when selecting the target image verification code satisfying the depth condition from the plurality of candidate image verification codes, since the machine does not have such a function, when it is determined that the image verification code to be verified conforms to the condition required by the target image verification code in the verification information, the probability that the user is the machine is low, and then the user is allowed to use the network resource.
Step 106: the user is not allowed to use the network resources.
When the image verification code to be verified selected by the user does not meet the condition that the target image verification code at least comprises the depth degree, the probability that the user is a machine is high, the user is not allowed to use the network resources in the step, and the purpose of preventing the machine from using the network resources is further achieved.
In the embodiment of the application, the depth degrees of the original image and the identification image in the same coordinate region correspond to each other, and a user needs to determine a target image verification code meeting the depth degree condition of the relevant region from a plurality of candidate image verification codes selected from the original image or the identification image based on the corresponding relationship. Because the corresponding relation of the original image and the identification image in the depth degree of the same coordinate area has higher requirements on the visual function of the depth degree judgment of the user, the machine is more difficult to identify the target image verification code at least comprising the depth degree condition, and furthermore, the identification rate of the machine to the target image verification code can be reduced.
In addition, in this embodiment, the condition for selecting the target image verification code from the plurality of candidate image verification codes included in the prompt information further includes: the position condition used for limiting the position of the target image verification code in the identification image further reduces the probability that the machine selects the target image verification code from the plurality of candidate image verification codes, and further, the recognition rate of the machine recognizing the target image verification code from the plurality of candidate image verification codes is easier to reduce.
In the embodiment described in fig. 1, the target image verification code at least meeting the depth degree condition is selected from the multiple candidate image verification codes based on the multiple areas with different depth degrees in the original image and the identification image, respectively.
Referring to fig. 2, a flow chart of an embodiment of a method for generating a logo image in the present application is shown, which may include the following steps:
step 201: and obtaining the depth value representing the depth degree of the object described by each pixel point in the original image.
In this embodiment, first, a depth value corresponding to a depth degree of an object described by each pixel point in an original image is obtained. The depth value corresponding to each pixel point in the original image can be obtained through the depth image corresponding to the original image.
Step 202: according to the corresponding depth value of each pixel point in the original image, dividing the pixel points in the original image into: at least two sets of different depth degrees are characterized.
In this embodiment, after obtaining the depth value corresponding to each pixel point in the original image, then, according to the depth value corresponding to each pixel point, dividing the pixel points in the original image into: and characterizing the sets of different depth degrees to obtain at least two sets.
Specifically, the process of dividing the pixel points in the original image into at least two sets representing different depth degrees may specifically include: step A1-step A3:
step A1: and determining a depth value range formed by the maximum depth value and the minimum depth value.
After obtaining the depth values corresponding to the pixel points in the original image, then, in this step, the maximum value and the minimum value in the depth values are determined. After the maximum depth value and the minimum depth value are determined, a range of depth values is then determined that is comprised of the minimum depth value and the maximum depth value. For example, if the minimum depth value is 10 and the maximum depth value is 255 among the depth values corresponding to the pixel points in the original image, the depth value range is [10, 255 ].
Step A2: the depth value range is divided into at least two target depth value ranges.
After the depth value range is determined, the determined depth value range is divided into at least two target depth value ranges, for example, the depth value range is [10, 255], in this step, the [10, 255] may be divided into two depth value ranges of [10, 128] and [129, 255], for convenience of description, the present embodiment refers to the at least two divided depth value ranges as the at least two target depth value ranges, for example, the two depth value ranges of [10, 128] and [129, 255] are referred to as the two target depth value ranges.
It should be noted that, when the depth value range is divided into at least two target depth value ranges, the selected division point is not specifically limited in this embodiment, as long as the at least two target pixel ranges obtained after division include the target depth value range with the minimum depth value and the target depth value range with the maximum depth value, and the at least two target depth value ranges form the depth value range from the minimum depth value to the maximum depth value.
Step 203: and aiming at each target depth value range, dividing pixel points, corresponding to the target depth value range, of the depth value in the original image into a pixel point set, and obtaining at least two sets corresponding to at least two different depth value ranges.
After determining at least two target depth value ranges, in this step, for each target depth value range, determining pixel points of the original image whose corresponding depth values belong to the target depth value range, and dividing the pixel points located in the target depth value range into a set, at this time, obtaining at least two sets corresponding to at least two different depth value ranges.
Step 204: and marking the pixel points of different sets by adopting different identifications.
After at least two pixel point sets are obtained, the pixel points in the same set are marked by the same identification, wherein the identification can be a symbol, and the pixel points in different sets are marked by different identifications. For example, the pixel points in the same set are set to have the same pixel value, that is, the pixel points in the same set show the same color, and the pixel points in different sets are marked with different colors, so that the regions with the same depth degree show the same color, and the regions with different depth degrees show different colors.
Step 205: and determining the marked image as the identification image.
After the pixels in each set are marked, a marked image is obtained, and this embodiment determines the marked image as an identification image.
In this embodiment, the pixels in the original image are divided into at least two sets by the depth values corresponding to the pixels in the original image, the pixels in each set are marked by the same identifier, the pixels in different sets are marked by different identifiers, and then the identifier images with different depth degrees and different identifier marks are obtained.
