Abstract
A camera parameter estimating method includes: obtaining a plurality of image frames in time series, the image frames being photographed by a camera installed in a mobile body; detecting at least one straight line from a central portion of a first image frame group including one or more first image frames among the plurality of image frames; detecting a plurality of curves corresponding to the straight line from a second image frame group including one or more second image frames at a later time than an image frame from which the straight line is detected based on a feature quantity of the detected straight line; and estimating a parameter of the camera based on the plurality of curves.
Claims14
A non-transitory computer-readable storage medium storing a camera parameter estimating program for causing a computer perform a process comprising:
- obtaining a plurality of image frames in time series, the image frames being photographed by a camera installed in a mobile body;
- detecting at least one straight line from a central portion of a first image frame group including one or more first image frames among the plurality of image frames;
- detecting a plurality of curves corresponding to the straight line from a second image frame group including one or more second image frames at a later time than an image frame from which the straight line is detected based on a feature quantity of the detected straight line;
- and
- estimating a parameter of the camera based on the plurality of curves.
