    • Methods and apparatus for camera calibration based on multiview image geometry. A lens profiling module may estimate two or more mathematical models for correcting aberrations in images in a single pass from a set of calibration images captured with a camera/lens combination. For example, the module may estimate the lens aberrations of geometric distortion, lateral chromatic aberration, and vignette models in a single pass. The module may determine point correspondences, 3D transformations, and camera intrinsics for views of calibration charts captured in the images. The module estimates the mathematical models for the two or more types of aberrations from the information determined from the views of the calibration charts. The module may automatically determine an optimal model complexity when estimating the mathematical models. The estimated models may be written or appended to a lens profile for the camera/lens combination used to captured the calibration images.
    • 基于多视点图像几何的相机校准方法和装置。 透镜分析模块可以估计两个或更多个数学模型,用于在用相机/透镜组合捕获的一组校准图像的单次通过中校正图像中的像差。 例如,模块可以在单次通过中估计几何失真,横向色差和晕影模型的透镜像差。 该模块可以确定图像中捕获的校准图的视图的点对应,3D变换和相机内在信息。 该模块根据从校准图的视图确定的信息估计两种或多种类型的像差的数学模型。 当估计数学模型时,模块可以自动确定最佳模型复杂度。 估计的模型可以被写入或附加到用于捕获校准图像的相机/镜头组合的透镜轮廓上。

    • Method and apparatus for determining sensor format factors from image metadata in which one of multiple techniques is applied to determine a sensor format factor for a camera from information in the metadata. Information from the metadata may be used to identify which of the multiple techniques to use. For example, the camera make and model may be used to determine a particular technique to use. As another example, the presence or absence of particular attributes or values for particular attributes may be used in determining a particular technique. In one embodiment, a profile database may be searched according to information in the metadata to determine if a sensor format factor for the camera is in the database. If the sensor format factor for the camera is not in the database, other information in the metadata may be examined to determine a particular technique from among the plurality of techniques.

    • Methods and apparatus for matching image metadata to a profile database to determine image processing parameters are described. In embodiments, image metadata may be used to match input images against a profile database. For example, camera make and model information and/or lens make and model information may be retrieved from the image metadata corresponding to an input image and used to locate a best match profile in the profile database. Additional custom data may then be retrieved from the located profile to perform processing that may be optimized for a specific camera and lens that captured the images, and in some cases for particular camera settings. The profile database may be generated via a calibration process applied to each of a plurality of camera/lens combinations. In one embodiment, the additional custom data may be adjusted or scaled to account for differences in cameras, lenses, or settings.

    • Methods and apparatus for retargeting and prioritized interpolation of lens profiles. A lens profile file may include a set of lens sub-profiles. The camera body and/or settings described in the file may not exactly match that of camera body and/or settings used to capture a target image. A sub-profile processing module may perform a prioritized sub-profile sorting and interpolation method to generate an interpolated sub-profile that may be applied to the target image to correct aberrations including, but not limited to, geometric distortion, lateral chromatic aberration, and vignette. Thus, models generated for a reference camera at a variety of settings may be applied to a target image captured with the same type of lens but with a different camera and/or with different settings that are not exactly modeled in the lens profile file.
