First Claim
1. A vehicle including a system for determining the presence of an object in a passenger compartment of the vehicle, the system comprisinga first image receiver arranged at a first location in the vehicle for obtaining a first two-dimensional view of a portion of the passenger compartment including the object;
- a second image receiver arranged at a second location in the vehicle for obtaining a second two-dimensional view of the same portion of the passenger compartment, said second image receiver being arranged relative to said first image receiver such that three dimensions of the portion of the passenger compartment are encompassed by said first and second views, anda processor coupled to said first and second image receivers and that receives images from said first and second image receivers and determines whether an object is present in the portion of the passenger compartment based on the images obtained from both said first image receiver and said second image receiver.

Abstract
Vehicular system for determining the presence of an object in a passenger compartment of the vehicle includes a first image receiver arranged at a first location for obtaining a first two-dimensional view of a portion of the compartment, and a second image receiver arranged at a second location for obtaining a second two-dimensional view of the same portion of the compartment, the second image receiver being arranged relative to the first image receiver such that three dimensions of the portion of the compartment are encompassed by the first and second views. A processor receives images from the first and second image receivers and determines whether an object is present in the compartment based on the images. A reactive system, such as an airbag assembly, may be coupled to the processor and controlled thereby based on the determination of whether an object is present in the imaged portion of the compartment.

14. A method for determining the presence of an object in a passenger compartment of a vehicle, comprising:
-
obtaining using a first imaging system, a first image of a portion of the passenger compartment covering first and second dimensions of the passenger compartment, obtaining using a second imaging system, a second image of the same portion of the passenger compartment covering the first dimension and a third dimension of the passenger compartment such that three dimensions of the portion of the passenger compartment are encompassed by the first and second images obtained by the first and second imaging systems, and determining using a processor, whether an object is present in the passenger compartment based on the first and second images obtained by the first and second imaging systems. - View Dependent Claims (15, 16)

17. A method for ascertaining the identity of an object in a passenger compartment of a vehicle, comprising:
-
obtaining using a first imaging system, a first image of a portion of the passenger compartment covering first and second dimensions of the passenger compartment; obtaining using a first imaging system, a second image of the same portion of the passenger compartment covering the first dimension and a third dimension of the passenger compartment such that all three dimensions of the portion of the passenger compartment are encompassed by the first and second images obtained by the first and second imaging systems; and ascertaining using a processor, the identity of the object in the passenger compartment based on the first and second images obtained by the first and second imaging systems. - View Dependent Claims (18, 19)
