[ detailed description ] embodiments
For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present specification is provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step are within the scope of the present specification.
The terminology used in the embodiments of the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the specification examples and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the related art, the credibility of the user can be determined based on the credibility of the certificate, that is, the certificate used by the user can be subjected to anti-counterfeiting identification, and when the certificate is determined to be a legal certificate, the user is determined to be credible.
In the process of certificate anti-counterfeiting identification, in order to distinguish color printed pictures of certificates, electronic equipment is required to print a flash lamp on a certificate, and different conditions of the flash lamp on the certificate and a copy (including color printed pictures) are observed to distinguish whether the current certificate is a true certificate or a false certificate or a copy. If the flash lamp does not hit the certificate, the flash lamp anti-counterfeiting algorithm judges the true certificate as a false certificate, and the identification passing rate of the user is influenced.
Based on the above problems, embodiments of the present specification provide a method for acquiring a certificate picture, where an electronic device interacts with a user to provide a whole set of solution for detecting a flash lamp, so as to ensure that the electronic device acquires the certificate picture in an open state of the flash lamp, and meanwhile, detect whether the certificate is over-exploded.

After the user places the certificate in the rectangular frame 21, the electronic device captures the picture, and then detects the captured picture.
And 104, when the certificate image is included in the picture, acquiring the position of the certificate image in the picture, and generating a positioning frame surrounding the certificate image according to the position.
Specifically, a picture acquired by an electronic device may be detected through a Convolutional Neural Network (CNN) positioning model, the picture acquired by the electronic device is input into the CNN positioning model, the CNN positioning model outputs whether a current picture includes a certificate image, if the current picture includes the certificate image, the CNN positioning model may generate a positioning frame surrounding the certificate image according to a position of the certificate image in the current picture, as shown in fig. 3, fig. 3 is a schematic diagram of a positioning frame of the certificate image provided in an embodiment of this specification, and in fig. 3, a dashed frame 31 is the positioning frame surrounding the certificate image.
And step 106, determining the angle range and the distance range of the certificate corresponding to the certificate image according to the position of the positioning frame in the screen of the electronic equipment and the position of a flash lamp of the electronic equipment.
The angle range and the distance range comprise angle ranges and distance ranges which can be irradiated by a flash lamp of the electronic equipment.
Specifically, according to the image in the positioning frame, determining the current angle of the certificate corresponding to the certificate image may be: and determining the position of the corner point of the certificate image according to the image in the positioning frame, still referring to fig. 3, wherein 32 in fig. 3 is the focus of the certificate image.
After the position of the corner point of the certificate image is determined, the electronic equipment can determine the angle of the certificate corresponding to the certificate image according to the position of the corner point. The angles of the certificate corresponding to the certificate image comprise 3 angles of a pitch angle (pitch), a yaw angle (yaw) and a roll angle (roll) of the certificate.
And 110, if the current angle of the certificate corresponding to the certificate image is within the angle range and the distance between the certificate corresponding to the certificate image and the electronic equipment is within the distance range, the electronic equipment respectively performs picture acquisition on the certificate under the states that the flash lamp is turned off and turned on.
Specifically, if the angle of the certificate is within the angle range and the distance between the certificate and the electronic device is also within the distance range, the electronic device can prompt the user to keep the relative position between the electronic device and the certificate unchanged, and perform picture collection on the certificate in the states of turning off and turning on the flash lamp respectively. Certainly, in the specific implementation, the electronic device may collect the certificate picture in the state that the flash lamp is turned off, and then collect the certificate picture in the state that the flash lamp is turned on; or the electronic equipment can collect the certificate picture in the state that the flash lamp is opened firstly, and then collect the certificate picture in the state that the flash lamp is closed; this embodiment is not limited to this.
And 112, if the current angle of the certificate corresponding to the certificate image is not in the angle range and/or the distance between the certificate corresponding to the certificate image and the electronic equipment is not in the distance range, prompting a user to correspondingly adjust the angle of the certificate and the distance between the certificate and the electronic equipment.
In the method for acquiring the certificate image, an electronic device detects the image acquired by the electronic device, when the image comprises the certificate image, the position of the certificate image in the image is acquired, a positioning frame surrounding the certificate image is generated according to the position, and then the angle range and the distance range of the certificate corresponding to the certificate image are determined according to the position of the positioning frame in a screen of the electronic device and the position of a flash lamp of the electronic device; determining the current angle of the certificate corresponding to the certificate image according to the image in the positioning frame; and determining the distance between the certificate corresponding to the certificate image and the electronic equipment according to the area of the certificate image and the screen area of the electronic equipment. And finally, when the current angle of the certificate corresponding to the certificate image is within the angle range and the distance between the certificate corresponding to the certificate image and the electronic equipment is within the distance range, the electronic equipment respectively collects the certificate in the states that the flash lamp is turned off and turned on, so that the certificate picture in the state that the flash lamp is turned on can be collected by the electronic equipment, and the accuracy of certificate anti-counterfeiting identification is improved.
