1. A method of generating parking availability information performed by a computer, the method comprising:
collecting actual measurement data corresponding to a reference point of a parking availability section based on a distance between parked vehicles from an image captured by a camera;
setting a reference line within a region of interest set from the image captured by the camera;
detecting at least one already parked vehicle from the image captured by the camera;
converting object area information corresponding to the detected at least one parked vehicle into real distance information;
calculating a length conversion parameter for converting a distance between parked vehicles into the real distance information; and
generating parking availability information that includes occupancy information of parked vehicles, of a parking target vehicle based on the real distance information,
wherein in the generating of the parking availability information of the parking target vehicle, the parking availability information that includes occupancy information of parked vehicles and the parking availability section based on the distance between the parked vehicles is generated from the real distance information set for the reference line,
wherein the converting of the object area information into the real distance information includes converting the object area information into the real distance information based on initially collected actual measurement data and a length conversion parameter,
wherein the calculating of the length conversion parameter for converting the distance between the parked vehicles into the real distance information includes:
calculating an inter-pixel Euclidean distance between two points corresponding to the actual measurement data in the image captured by the camera;
converting the calculated inter-pixel Euclidean distance so that a distance for each pixel between the two points increases proportionally by the length conversion parameter in a direction of a farthest point among the two points; and
calculating the length conversion parameter based on an actual length between the two points included in the actual measurement data and a conversion result.
