Calibration of fixed image-capturing device for predicting driving lane

A method, comprising:

• identifying, by circuitry, in a first image of a calibration lane of a first object, a plurality of lines parallel to the calibration lane;
• determining, by the circuitry, for each row of pixels in the first image, an observed width between the plurality of lines;
• estimating, by the circuitry, for each row of pixels in the first image, column values based on the observed width of a corresponding row of pixels, a first object width of the first object, and an actual lane width between the plurality of lines;
• and
• storing, by the circuitry in a memory, the estimated column values for each row of pixels, wherein a driving lane for the first object is predicted based on the stored column values, and wherein a second object in a second image is analyzed for impending collision with the first object when the second object is detected in the driving lane of the first object.
