Embodiment Construction

[0017] 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.

[0018] The inventors of the present application found that the images collected by the wide-angle lens have the characteristics of barrel distortion. If the characteristics of barrel distortion are considered when collecting data sets using the wide-angle lens, the data sets collected by the wide-angle lens can be directly applied to traditional vision. algorithm.

[0019] figure 1 A schematic block diagram showing a data set collector according to an embodiment of the present disclosure, such as figure 1 As shown, the data set collector includes a base 1, a turntable 2, a lens holder 3 and a control unit (not shown). Wherein, the base 1 is provided with a...

Abstract

The invention relates to a data set collector, belongs to the field of deep learning, and can enable images collected by a wide-angle lens to be directly applied to various traditional visual algorithms. The data set collector comprises a base, and a checkerboard which is designed according to the distortion characteristic of a wide-angle lens is arranged on the base; a turntable; a lens frame onwhich the wide-angle lens is fixed; and the control unit is used for controlling the rotary table to carry an object to be subjected to image information collection to move to a corresponding positionon the checkerboard according to the distortion effect of the checkerboard within the visual angle range of the wide-angle lens, so that the wide-angle lens can shoot the object located at the corresponding position.

Description

technical field [0001] The present disclosure relates to the field of deep learning, and in particular, to a data set collector. Background technique [0002] A wide-angle lens is a special lens with a wider angle of view and a shorter focal length than a standard lens. Due to the structural characteristics of the wide-angle lens, such as large viewing angle and short focal length, the collected images are distorted and cannot be directly applied to various traditional vision algorithms. Contents of the invention [0003] The purpose of the present disclosure is to provide a data set collector that enables images collected by a wide-angle lens to be directly applied to various traditional vision algorithms. [0004] According to the first embodiment of the present disclosure, a data set collector is provided, including: a base, on which a checkerboard designed according to the distortion characteristics of the wide-angle lens is arranged; a turntable; a lens holder, and t...
