In various embodiments, methods and systems are provided for calibrating vehicle cameras. In certain embodiments, a method includes obtaining a plurality of camera images from the camera based on a target positioned at a plurality of locations relative to the vehicle, wherein the target includes a plurality of dots arranged in rows and columns according to a random spacing, wherein the target further includes a plurality of enlarged dots arranged in an L shaped pattern in relation to a center of the target; estimating, by a processor, at least one of intrinsic parameters and extrinsic parameters based on the plurality of camera images; and storing, by a processor and in a data storage device, the at least one of intrinsic parameters and extrinsic parameters as calibration parameters associated with the camera.

    在各个实施例中,提供了用于校准车辆摄像机的方法和系统。在某些实施例中,一种方法包括基于位于相对于车辆的多个位置处的标靶,从摄像机获得多个摄像机图像,其中,标靶包括根据随机间隔以行和列布置的多个点,其中,标靶还包括相对于标靶的中心呈L形图案布置的多个放大点;通过处理器基于所述多个摄像机图像估计内部参数和外部参数中的至少一个;一级通过处理器并在数据存储设备中存储内部参数和外部参数中的至少一个作为与摄像机相关联的校准参数。
