Embodiment Construction
[0033] The present invention aims to provide an improved method and system for creating virtual 3D models of objects. Although various embodiments of the invention are described below, the invention is not limited to these embodiments and variations of these embodiments may well fall within the scope of the invention, which is itself limited only by the appended claims.
[0034] According to an embodiment of the present invention, figure 1 A schematic diagram of the 3D modeling process is shown. Object 105 is located in the spatial region. exist figure 1 , as an example, object 105 is a model of a cathedral. A voxel array 120 can be used to describe a spatial region, where each voxel V in the voxel array j A small element describing physical space, "j" is an index corresponding to a particular voxel, as will be understood by those skilled in the art. For the purposes of the modeling process, a particular voxel V is called if a portion of the object 105 is located within t...

There is provided a method for creating a voxel occupancy model. The voxel occupancy model is representative of a region of space which can be described using a three- dimensional voxel array. The region of space contains at least part of an object. The method comprises receiving first image data, the first image data being representative of a first view of the at least part of an object and comprising first image location data, and receiving second image data, the second image data being representative of a second view of the at least part of an object and comprising second image location data. The method also comprises determining a first descriptor, the first descriptor describing a property of a projection of a first voxel of the voxel array in the first image data, and determining a second descriptor, the second descriptor describing a property of a projection of the first voxel in the second image data. The method also comprises assigning an occupancy value to the first voxel based on the first and second descriptors, the occupancy value being representative of whether the first voxel is occupied by the at least part of an object.
Description
[0001] The present disclosure relates to the field of computer vision, and in particular to a method and system for creating a virtual 3D model of an object. Background technique [0002] Observing and understanding the 3D structure of the world from a sequence of 2D images, and especially generating 3D reconstructions from a sequence of 2D images, are important tasks in the field of computer vision. Creating virtual 3D models from image data has applications in many fields such as, but not limited to, robotics, self-driving cars, and augmented reality. Augmented reality involves projecting virtual objects into the physical (real) world around us. Virtual objects can be created from real objects so that they can be projected into these spaces. Second, for things like robotics, self-driving cars, and augmented reality, it can be important to be able to know where a device (phone, drone, car) is in the world, and a 3D model of the environment can be helpful.
