Abstract
Systems, methods, apparatus, and computer-implemented methods are provided for determining a camera calibration. The method includes accessing video data for a geographic area captured by a video camera. The video data is processed to detect a plurality of moving vehicles in the video data. A detection area is defined based on the plurality of moving vehicles. A plurality of line segments are identified for each of the plurality of vehicles detected in the video data. A plurality of vanishing points are estimated based on at least a subset of the plurality of line segments. A camera calibration is determined based on the plurality of vanishing points.
