Positioning an input 3d object in an input 3d scene

A non-transitory computer readable storage medium having recorded thereon a computer program having instructions for performing a method for automatically positioning an input 3D object representing a real object in an input 3D scene representing a room, the input 3D scene including a plurality of positioned 3D objects, the plurality of positioned 3D objects including positioned furniture 3D objects each representing a real piece of furniture, the method comprising:

• obtaining a dataset including information about objects of a plurality of rooms, the information including:
• a classification of the objects of the plurality of rooms,
• counts each of a set consisting of each occurrence of a respective pair including a same first real object and a same second real object in a room, wherein the first real object and the second real object of each occurrence of each respective pair are arranged according to a mutual arrangement relationship from a predetermined set of one or more mutual arrangement relationships, and
• information regarding the relative positioning of the first real object and the second real object in each occurrence of each pair;
• executing computer program instructions that include:
• attempting to identify in the dataset one or more first pairs each including the input 3D object and a respective positioned 3D object of the input 3D scene,
• when no first pair is identified, attempting to identify in the dataset one or more second pairs each including only one of the input 3D object and a respective positioned 3D object of the input 3D scene, and an equivalent object for the other one, a given real object being an equivalent object for another given real object when the given real object has the same classification than the another given real object and the given real object is, among the set consisting of each real object of the same classification present in the dataset, the closest in size to the another given real object, and
• when no first pair is identified and no second pair is identified, attempting to identify in the dataset one or more third pairs each including an equivalent object for the input 3D object and an equivalent object for a respective positioned 3D object of the input 3D scene;
• outputting one or more pairs among the set consisting of each identified pair and the counts of the one or more identified pairs, the outputting being based on the set consisting of each count for a respective identified pair of the set consisting of each identified pair;
• for each outputted pair, determining a respective position of the input 3D object in the input 3D scene based on the information regarding the relative positioning of the first real object and the second real object in each occurrence of the outputted pair;
• and
• positioning the input 3D object according to the respective position determined for one of the one or more outputted pairs.

A computer system comprising:

• a processor coupled to a memory, the memory having recorded thereon a computer program having instructions for automatically positioning an input 3D object representing a real object in an input 3D scene representing a room, the input 3D scene including a plurality of positioned 3D objects, the plurality of positioned 3D objects including positioned furniture 3D objects each representing a real piece of furniture that when executed by the processor causes the processor to be configured to:
• obtain a dataset including information about objects of a plurality of rooms, the information including:
• a classification of the objects of the plurality of rooms,
• counts each of a set consisting of each occurrence of a respective pair including a same first real object and a same second real object in a room, wherein the first real object and the second real object of each occurrence of each respective pair are arranged according to a mutual arrangement relationship from a predetermined set of one or more mutual arrangement relationships, and
• information regarding the relative positioning of the first real object and the second real object in each occurrence of each pair;
• attempt to identify in the dataset one or more first pairs each including the input 3D object and a respective positioned 3D object of the input 3D scene;
• when no first pair is identified, attempt to identify in the dataset one or more second pairs each including only one of the input 3D object and a respective positioned 3D object of the input 3D scene, and an equivalent object for the other one, a given real object being an equivalent object for another given real object when the given real object has the same classification than the another given real object and the given real object is, among the set consisting of each real object of the same classification present in the dataset, the closest in size to the another given real object;
• when no first pair is identified and no second pair is identified, attempt to identify in the dataset one or more third pairs each including an equivalent object for the input 3D object and an equivalent object for a respective positioned 3D object of the input 3D scene;
• output one or more pairs among the set consisting of each identified pair and the counts of the one or more identified pairs, the output being based on the set consisting of each count for a respective identified pair of the set consisting of each identified pair;
• for each output pair, determine a respective position of the input 3D object in the input 3D scene based on the information regarding the relative positioning of the first real object and the second real object in each occurrence of the outputted pair;
• and
• position the input 3D object according to the respective position determined for one of the one or more outputted pairs.
