Problems solved by technology

[0002] Certificates refer to legal certificates such as ID cards, passports, business licenses, etc. At present, some website platforms need to collect certificate images to complete the entry of certificate information, and the way to collect certificate images is usually for users to use smart terminals such as mobile phones. However, due to the limited shooting level of the user, the quality of the captured document image will inevitably vary greatly, and unnecessary shaking will inevitably occur during the user's shooting process, resulting in distortion of the captured document image.

Embodiment 1

[0070] refer to figure 1 , which shows a flowchart of steps of an image processing method provided by an embodiment of the present disclosure, and the image processing method may specifically include the following steps:

[0071] Step 101: Acquiring an image sequence corresponding to an object to be photographed.

[0072] In the embodiment of the present disclosure, the shooting object refers to the object used for image acquisition, and the shooting object may be an object such as a certificate (such as an ID card, a business license, a passport, etc.) to be photographed. Specifically, it may be determined according to the actual situation .

[0073] Of course, in the present disclosure, the photographed object especially refers to the user's certificate.

[0074] An image sequence refers to a sequence composed of a plurality of consecutive images obtained by continuously photographing an object. There may be 8 images or 10 images in the captured image sequence, which is no...

Embodiment 2

[0102] refer to figure 2 , which shows a flowchart of steps of an image processing method provided by an embodiment of the present disclosure, and the image processing method may specifically include the following steps:

[0103] Step 201: Use a preset camera to shoot a preset area according to a first shooting parameter.

[0104] In the embodiment of the present disclosure, the preset camera refers to a camera used to collect images corresponding to the shooting object, and the preset camera may be a mobile terminal (such as a mobile phone, etc.) used by a user.

[0105] The photographed object refers to the object used for image acquisition, and the photographed object may be an object such as a certificate (such as an ID card, a business license, a passport, etc.) to be photographed. Specifically, it may be determined according to the actual situation.

[0106] Of course, in the present disclosure, the photographed object especially refers to the user's certificate.

Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring an image sequence corresponding to a shooting object; acquiring a reference image in the image sequence; establishing a three-dimensional model according to the reference image and a plurality of frames of continuous images continuous with the reference image in the image sequence; determining the length-width ratio of the shooting object according to the three-dimensional model; and performing projection correction on the reference image according to the length-width ratio to obtain a corrected image corresponding to the shooting object. According to the invention, distortion of the image can be avoided.
