Embodiment Construction

[0027] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0028] The inventor of the present application analyzed the coordinates of the pixel points within the entire viewing angle range of the wide-angle lens, and found that the characteristics of the same object at different positions within the wide-angle lens viewing angle range will be different. The distortion of the wide-angle lens is characteristic, that is, the distortion of the wide-angle lens Distortion is mainly barrel distortion. Although the curvature of distortion has no fixed law, the distribution law of distortion is fixed. Therefore, if when using a wide-angle lens to collect image data sets, the target is only photographed and features are collec...

Abstract

The invention relates to a data set collection method and device, a storage medium and electronic equipment, belongs to the field of deep learning, and can directly apply an image data set collected by a wide-angle lens to a target detection related algorithm. The data set acquisition method comprises the steps of receiving an image when an object is located in an i sub-view-angle range ofa wide-angle lens, dividing the whole view-angle range of the wide-angle lens into N sub-view-angle ranges, and enabling i to be greater than or equal to 1 and less than or equal to N; And based on the distortion characteristic of the wide-angle lens, expanding the image of the object in the rest sub-visual-angle ranges of the wide-angle lens by using the received image in the ith sub-visual-anglerange.

Description

technical field [0001] The present disclosure relates to the field of deep learning, and in particular, to a method and device for collecting data sets, a storage medium, and electronic equipment. Background technique [0002] The wide-angle lens has a large viewing angle and a short focal length, which leads to distortion of the objects in the images it collects, which in turn prevents the characteristics of the same object from being directly used by various image processing algorithms. At present, the mainstream method to deal with this distortion is to correct the distorted image first. However, the correction effect of the current distortion correction algorithm for wide-angle lenses is not good, and the corrected image is only suitable for human observation, and it is not possible to apply the corrected picture to the target detection related algorithm. Contents of the invention [0003] The purpose of the present disclosure is to provide a data set collection metho...
