Embodiment 1

[0043] The baseline of the binocular camera module is adjustable, that is, the distance between the left and right cameras is adjustable, and the distance between the filter automatic matching module can be adjusted according to the distance between the cameras. Before use, the filter module needs to be manually calibrated, that is, rotated to the zero point correction position, at this time, the polarization axis of the filter is perpendicular to the horizontal line.

[0044]The two-color reflection model analysis is performed on the pixels in the attention area of ​​the left and right images, and the maximum specular reflection component is separated. After the filter is rotated to the orthogonal output of the maximum specular reflection component, the maximum specular reflection component is effectively suppressed.

Abstract

The invention provides an adaptive filter matching binocular camera module and a stereo matching method thereof. The binocular camera module comprises a binocular image feature matching module; the distance between two cameras of the binocular camera module is adjustable; filter adaptive matching modules are arranged on the two cameras; the filter self-adaptive matching module comprises a rotatingmodule provided with a polarization filter; the polarization filter is located at the light inlet end of the camera. Polarization filters of the filter adaptive matching module can be driven by the rotating module to rotate independently. The invention discloses a camera module capable of suppressing noise and improving image stereo matching by using a polarization filter in the field of binocular stereo vision application.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a binocular camera module for adaptive filter matching and a stereo matching method thereof. Background technique [0002] If an image is overexposed, a lot of important information will be hidden; shadows will cause edge misjudgment; image unevenness will make threshold selection difficult. [0003] Due to the influence of polarized light, the image will appear chaotic light, heavy light, and object reflection. In the industrial field, high-resolution cameras are often used to detect scratches and cracks, etc., but the surface of smooth workpieces lacks texture features, and stable features cannot be obtained due to the influence of specular reflection. [0004] According to the principle of perspective imaging, it is known that the three-dimensional coordinate information corresponding to the target point cannot be obtained through the information of a single image, and the bi...
