1. A device for searching a parking space, the device comprising:
at least one space detection sensor mounted on a vehicle; and
a controller configured to:
analyze sensed information obtained through the at least one space detection sensor and to recognize space and object information within a parking lot;
predict a distribution of available parking spaces in the parking lot based on the recognized space and object information; and
determine an optimal available parking space based on the distribution of the available parking spaces and characteristics of a driver,
wherein the controller is further configured to:
analyze the sensed information obtained through the at least one space detection sensor of the vehicle and generate a parking lot partial map including a parking line, locations of parked vehicles, and a location of a host vehicle,
select a recognized road in the parking lot partial map as a travelable space;
reflect an available parking space among the available parking spaces recognized while the vehicle travels to the travelable space in the parking lot partial map,
assign a weight accordingly when the available parking spaces are successively recognized, and reflect the weight on the parking lot partial map, and
select a parking space node on a travelable space closest to the available parking space.
