Problems solved by technology

[0003] The original image captured by the dual fisheye panoramic camera is a dual fisheye image. When using a waterproof housing and not using a waterproof housing, there are usually slight differences in the size of the fisheye circle in the fisheye image. However, if simple thresholding Classification often cannot get the optimal classification effect

Embodiment 1

[0029] see figure 1 According to the first embodiment of the present invention, the automatic identification method for the waterproof casing of the panoramic camera includes the following steps:

[0030] S101. Obtain a number of fisheye images taken by the panoramic camera without wearing a waterproof case and a number of fisheye images taken by wearing a waterproof case, as a data set;

[0031] The panoramic camera is a double fisheye panoramic camera, which can be a panoramic camera of various brands and models, and the waterproof case can be a waterproof case of various materials suitable for the corresponding camera;

[0032] It should be noted that the data set is a double fisheye image collected under the combination of several different cameras and corresponding waterproof casings of different materials. Several images in the data set include more than a thousand images. The size of these images is the same, and the more the number, the final The better the recognitio...

Embodiment 2

[0042] see figure 2 The automatic identification device for the waterproof case of the panoramic camera provided in Embodiment 2 of the present invention includes:

[0043] The acquisition module 11 is used to acquire some fisheye images taken by the panoramic camera without wearing a waterproof case and some fisheye images taken by wearing a waterproof case, as a data set;

[0044] Feature extraction module 12, is used for extracting the feature of each piece of fisheye image in data set respectively;

[0045] The sample marking module 13 is used to mark the features described in the fisheye image taken by wearing a waterproof case as a positive sample, and the features described in the fisheye image taken without wearing a waterproof case are marked as a negative sample;

[0046] Training module 14, is used for inputting described positive sample and negative sample to SVM support vector machine and trains, obtains classification model;

[0047] The classification module ...

Embodiment 3

[0052] Embodiment 3 of the present invention provides a computer-readable storage medium. When the computer program is executed by a processor, the steps of the method for automatically identifying a waterproof case of a panoramic camera as provided in Embodiment 1 of the present invention are implemented.

Abstract

The invention provides a method, a device and a portable terminal for automatically identifying a waterproof casing of a panoramic camera. The method includes: obtaining a number of fisheye images taken by a panoramic camera without a waterproof case and a number of fisheye images taken by wearing a waterproof case as a data set; respectively extracting the characteristics of each fisheye image in the data set; The feature mark described in the fisheye image taken by the shell is a positive sample, and the feature mark described in the fisheye image taken without wearing a waterproof shell is a negative sample; the positive sample and negative sample are input to the SVM support vector machine for Train to obtain a classification model; use the classification model to classify the fisheye images to be classified, so as to identify whether to wear a waterproof case when shooting with the panoramic camera. On the basis of collecting a large amount of statistical data, the present invention classifies the images by using the support vector machine according to the difference in the radius of the fish-eye circle, and can accurately identify whether the camera wears a waterproof case when shooting.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an automatic identification method, device and portable terminal for a panoramic camera waterproof case. Background technique [0002] Panoramic cameras are widely used. When using a panoramic camera underwater, in order to achieve a waterproof effect, it is often used with a waterproof case. The use of a waterproof case will affect the image stitching to a certain extent. Therefore, when using the traditional stitching algorithm, it is first necessary to determine whether the image is taken by a panoramic camera wearing a waterproof case. Therefore, it is very important to be able to identify the waterproof case. [0003] The original image captured by the dual fisheye panoramic camera is a dual fisheye image. When using a waterproof housing and not using a waterproof housing, there are usually slight differences in the size of the fisheye circle in the fisheye image....
