Patent attributes
A computer implemented method, computer program product, and computer system for determining camera calibration data. The computer system receives geo-positional data of a moving object, wherein the geo-positional data is associated with an indicator (112). The computer system receives further a sequence of frames (140) from the at least one camera (150), wherein at least one frame has a picture of the moving object (118) with a structure and with an encoded version of the indicator which are optically recognizable. The indicator associated with the at least one frame is extracted by decoding (170) the optically encoded version of the indicator of the at least one frame. The geo-positional data of the moving object which is in the picture of the at least one frame is obtained by matching (172) the indicator associated with the geo-positional data of the moving object and the decoded indicator associated with the at least one frame. At least one reference point of the at least one frame is identified by analyzing the optically recognizable structure in the picture of the at least one frame. The camera calibration data of the at least one camera is determined by applying a geometric transformation (174) on the at least one reference point and its associated geopositional data of the moving object which is in the at least one frame.
