Abstract

The invention provides a device and a method for correcting a 3D camera. The device for correcting the 3D camera comprises an image conversion module, a corner detection module, a corner matching module, an error calculation module and an adjusting module, wherein the error calculation module is used for calculating absolute values of x coordinates of corners of a left image and differences between x coordinates of corners of a right image and averaging all the differences to obtain errors; the adjusting module generates feedback signals according to the errors to drive the image conversion module to adjust the left image or the right image along the X axis, so that distances between the x coordinates of the matched corners and the Y axis are equal. With the adoption of the device and the method for correcting the 3D camera, position errors caused during surface mounting of two cameras of the 3D camera can be compensated, and a 3D image with the better effect can be generated finally by the aid of the corrected left and right images.

Description

technical field [0001] The invention relates to the field of image processing and image recognition, in particular to a device and method for calibrating a 3D camera. Background technique [0002] In order to use mobile phones to collect and generate 3D images, dual cameras are often installed on the mobile phone, and the position of the dual cameras during the placement process is prone to errors, resulting in the final generation of awkward 3D images from the collected image data. [0003] In order to solve the above technical problems, the present invention provides a device and method for calibrating a 3D camera to compensate for adverse effects caused by camera patching errors. Contents of the invention [0004] The present invention provides a device and method for calibrating a 3D camera, by converting the collected 3D image data into a grayscale image, and splitting the grayscale image into a left image and a right image, and then correcting the left image and the ...
