Abstract
A height estimation method performed by a height estimation apparatus includes a first feature point extraction step of extracting a feature point coordinate, a first coordinate estimation step of estimating a coordinate of a first subject frame, a pre-generation step of deriving a height of the first subject frame and generating a distance addition pattern and a correction coefficient for an individual missing pattern, a second feature point extraction step of extracting a feature point coordinate from a second input image, a second coordinate estimation step of estimating a coordinate of a second subject frame and estimating a coordinate of an object frame, a subject data selection step of selecting the individual missing pattern and the correction coefficient in accordance with the feature point coordinate, an object data selection step of selecting an object height, and a height estimation step of adding up a distance between a feature point coordinate and another feature point coordinate extracted in accordance with the missing pattern and deriving an estimated value of a height of the subject in accordance with a result of adding up the distance, the correction coefficient, the object height, and the coordinates of the object frame.
