The invention discloses a method for calibrating a camera, and the method comprises the steps: obtaining a plurality of images photographed by the camera, and the images comprise the image of a targetobject; receiving geographic position information of the target object at a first moment; selecting an image shot at a first moment from the plurality of images, and extracting image position information of the target object in the image from the selected image; and calibrating the camera according to the extracted image position information and the received geographical position information, soas to determine the geographical position information of each object in the shooting range of the camera according to the image shot by the camera based on the calibration result. The invention also discloses roadside sensing equipment and a calibration system adopting the calibration method.

    本发明公开了一种对摄像头进行标定的方法,包括步骤:获取该摄像头拍摄的多张图像,这些图像包括目标对象的图像;接收目标对象在第一时刻的地理位置信息;从多张图像中选择在第一时刻拍摄的图像,并从所选择的图像中提取目标对象在图像中的图像位置信息;以及根据所提取的图像位置信息和所接收的地理位置信息对摄像头进行标定,以便基于标定结果,根据摄像头所拍摄的图像来确定在摄像头拍摄范围内的各个对象的地理位置信息。本发明还公开了一种采用该标定方法的路侧感知设备和标定系统。
