摘要： The present invention provides a method and a device for calibration applied to the field of image processing. The method includes: acquiring a common two-dimensional image and an infrared image of a calibration object, wherein the calibration object carries a first pattern; calculating coordinates of the first pattern in the common two-dimensional image, acquiring coordinates of the first pattern in a global coordinate system, and calculating intrinsic parameters of a first camera device capturing the common two-dimensional image; and calculating coordinates of the first pattern in the infrared image, acquiring the coordinates of the first pattern in the global coordinate system, and calculating intrinsic parameters of a second camera device capturing the infrared image. The method for calibration is capable of enhancing calibration efficiency by a simple calibration method when calibrating a depth camera device.

摘要： The present invention provides a method and a device for image rectification, which are applied in the field of image processing. The method includes: receiving two images, the two images are images of a target object captured from different viewpoints; performing an epipolar rectification on the two images; rectifying the two images after the epipolar rectification based on the image contents; and splicing the two images after the rectification based on the image contents. The method can rectify the images captured from different viewpoints, thereby ensuring the pixel alignment, and avoiding visual discomfort to the viewer.

摘要： The present invention provides a method and a device for image rectification, which is applied to the field of image processing. The method includes: receiving two images, wherein the two images are images of a target object captured at different viewpoints, and an image capturing device configured to capture the two images, includes a first image capturing device and a second image capturing device; determining positions of corresponding feature point pairs in the two images; and aligning the two images according to the positions of the feature point pairs and parameters of the first image capturing device and the second image capturing device. The above-mentioned method can rectify the images captured at different viewpoints, thereby ensuring the alignment of pixels, and avoiding visual discomfort of the viewer.

摘要： An apparatus for image processing includes a processor and a depth camera. The processor obtains a first two-dimensional image and focusing information of the first two-dimensional image, and obtains depth information of a part or all of a content captured in the first two-dimensional image via the depth camera. The processor determines a background area of the first two-dimensional image according to the focusing information. The processor also performs bokeh on the background area of the first two-dimensional image according to the depth information.

摘要： Disclosed in the present disclosure is a calibration parameter obtaining method and apparatus, a processor, and an electronic device. The method includes that: multiple image collection elements are used to capture a calibration image in a calibration scene to obtain multiple images; point sets are obtained from the multiple images, and the point sets are imaging points corresponding to three-dimensional points on the surface of the calibration image in the multiple images; and calibration parameters to be used of the multiple image collection elements are obtained according to the point sets. The present disclosure solves the technical problem in the related art that multiple cameras cannot be integrally calibrated.
