Embodiment 1

[0050] figure 1 It is a flow chart of a photographing processing method provided in Embodiment 1 of the present invention. The method in this embodiment can be executed by a photographing processing device, which can be realized by means of hardware and / or software, and generally can be integrated into a function in the device. The method of this embodiment specifically includes:

[0051] 101. According to a feature point detection rule, detect a first feature point of an object to be tested in a first image acquired by a first camera and a second feature point in a second image acquired by a second camera.

[0052] In this embodiment, the first camera and the second camera may be the same or different, and they are used to simultaneously view the same scene. Generally speaking, when a photographing device uses dual cameras to take pictures, it will obtain respective images through the dual cameras. Similarly, in this embodiment, when the dual cameras are used to take pictu...

Embodiment 2

[0068] figure 2 It is a flowchart of a photographing processing method provided in Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, after calculating the vertical distance between the target to be measured and the camera device according to the parallax value and the principle of binocular distance measurement, the optimization further includes: according to the pre-stored Test the corresponding relationship between the vertical distance and the actual vertical distance, and correct the calculated vertical distance.

[0069] Further, the first feature point and the second feature point are matched according to the feature point matching rule, and the disparity value of the target to be tested is determined according to the matching result, which is optimized as follows: according to the feature point matching rule, the first feature point and the second feature point are matched. Two feature points...

Embodiment 3

[0099] image 3 It is a flowchart of a photographing processing method provided in Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, the camera device will be focused according to the calculated vertical distance, and the optimization is: obtain the standard vertical distance and focus of the pre-stored subject to reach the camera device. The corresponding relationship between the moving distances of the motors; determine the target moving distance of the focus motor according to the calculated vertical distance and the obtained corresponding relationship; move the focusing motor according to the target moving distance to focus on the camera device.

[0100] Further, after focusing the photographing device by moving the focus motor according to the moving distance of the target, the optimization further includes: returning to the execution according to the feature point detection rule to det...

Abstract

Embodiments of the invention disclose a photographic processing method and device, equipment and a storage medium. The method comprises the following steps of detecting a first feature point of a to-be-detected target in a first image obtained by a first camera and a second feature point of the to-be-detected target in a second image obtained by a second camera according to a feature point detection rule; matching the first feature point and the second feature point according to a feature point matching rule and determining a parallax value of the to-be-detected target according to a matching result; computing a vertical dimension between the to-be-detected target and camera equipment according to the parallax value and a binocular ranging principle; and focusing the camera equipment according to the vertical dimension obtained through computation. The technical scheme in the embodiments of the invention solves the technological defect of lower precision of automatic focusing of a mobile terminal in the prior art, and the camera equipment, such as the mobile phone, can carry out automatic focusing during shooting quickly, simply and accurately.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a photographing processing method, device, device, and storage medium. Background technique [0002] With the development of science and technology, the camera level of mobile phones has been greatly improved, and mobile phones have now successfully replaced cameras and become the most commonly used camera equipment for people. [0003] The mobile phone realizes the automatic focusing function through a set of data calculation methods integrated in the mobile phone ISP (Image Signal Processing, Image Signal Processor). When the viewfinder captures the most original image, the image data will be sent to the ISP. The ISP will analyze the image data and check the density difference between adjacent pixels in the original image. If the focus of the original image is inaccurate, then Adjacent pixel densities will be very close, and the ISP will use...
