AI Technical Summary

Benefits of technology

This patented technology helps improve stereoscopic imagery accuracy when capturing 360 degree images with an eyewear lens attached thereto through different ways such as binoculography or polarization glasses. By measuring how well these methods work for each location within the scene being captured, it can accurately determine where objects are located relative to other cameras during capture. These techniques involve comparing specific areas from both eyes together to find corresponding points that correspond to those parts of interest (such as faces). Based upon their distances and directions, they then adjust focus accordingly. Overall, this technique allows users to see better quality three dimensional scenes even if we don't have them themselves.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the speed and efficiency of robot or car radar systems' calibrations for binoculators due to their unique characteristics such as being able to accurately measure both distance from objects within range (distance) while also accounting for environmental factors like temperature changes without affecting how well they operate over different temperatures.

Abstract

The invention discloses a binocular camera depth calibration method, device and system and a storage medium, and the method comprises the steps: obtaining images of a two-dimensional code calibrationplate at a plurality of different positions, and obtaining an image disparity map of the two-dimensional code calibration plate; obtaining a two-dimensional code template image of the target area; matching the two-dimensional code template image with all images corresponding to the monocular camera in the image calibration plate area so as to determine and store matching area information; determining a region position of the two-dimensional code template image in the disparity map according to the matching region information, and calculating an average disparity value of the region position; obtaining a plurality of groups of average parallax values through the extraction of a plurality of image calibration plate regions, and calculating a final parallax value according to the plurality ofgroups of average parallax values; and performing depth calibration of the binocular camera according to the final parallax value. Based on binocular vision parallax information, rapid and accurate depth calibration is realized by using a method of matching the position of a two-dimensional code calibration plate.
