Object recognition device, object recognition method and program

1. An object recognition device comprising:

at least one memory configured to store a program; and

at least one central processing unit (CPU) coupled to the memory and configured to execute the program to:

acquire external field information generated by a sensor arranged on a movable body;

acquire object position information indicating a position of an object existing around the movable body, and attribute information including kind information indicating a kind of the object; and

select a recognition method corresponding to the kind of the object based on the acquired kind information, from plural recognition methods of recognizing the object from the external field information positioned within an object prediction range determined based on the object position information; and

recognize the object by the selected recognition method.

2. The object recognition device according to claim 1 , wherein the at least one CPU is further configured to:

acquire a first object position information indicating a position of a first object, a first attribute information indicating an attribute of the first object, a second object position information indicating a position of a second object different from the first object, and a second attribute information indicating an attribute of the second object,

extract a first prediction information, predicted to include information indicating the first object, from the external field information based on the first object position information, and recognizes the first object based on the first prediction information by a first recognition method determined based on the first attribute information, and

extract a second prediction information, predicted to include information indicating the second object, from the external field information based on the second object position information, and recognizes the second object based on the second prediction information by a second recognition method determined based on the second attribute information.

3. The object recognition device according to claim 1 , wherein the at least one CPU is further configured to recognize the object by a different method for each of the attributes of the objects.

4. An object recognition method comprising:

a first acquisition process configured to acquire external field information generated by a sensor arranged on a movable body;

a second acquisition process configured to acquire object position information indicating a position of an object existing around the movable body, and attribute information including kind information indicating a kind of the object; and

a recognition process configured to:

select a recognition method corresponding to the kind of the object based on the acquired kind information, from plural recognition methods of recognizing the object from the external field information positioned within an object prediction range determined based on the object position information, and

recognize the object by the selected recognition method.

5. A non-transitory computer-readable medium storing a program executed by a computer in an object recognition device, the program causing the computer to:

acquire external field information generated by a sensor arranged on a movable body;

acquire object position information indicating a position of an object existing around the movable body, and attribute information including kind information indicating a kind of the object; and

select a recognition method corresponding to the kind of the object based on the acquired kind information, from plural recognition methods of recognizing the object from the external field information positioned within an object prediction range determined based on the object position information; and

recognize the object by the selected recognition method.
