Abstract
An object management system includes an acquisition means for acquiring an image in which a surface of a registration target object, having a circle and a handwritten character drawn thereon, is captured, a generation means for detecting an ellipse corresponding to the circle from the image and generating a registration image in which the image is applied with projective transformation such that the ellipse becomes a circle, and a registration means for writing the registration image into a storage means as data for determining the sameness of the registration target object.
Claims11
An object management system comprising:
- a first memory containing program instructions;
- and
- a processor coupled to the memory, wherein the processor is configured to execute the program instructions to:
- acquire a first image in which a surface of a registration target object is captured, the surface having a first circle and a first handwritten character drawn on the surface;
- detect a first ellipse corresponding to the first circle from the first image;
- generate a registration image in which the first image is applied with projective transformation such that the first ellipse becomes a circle;
- and
- write the registration image into a second memory as data for determining sameness of the registration target object.
An object management method comprising:
- acquiring a first image in which a surface of a registration target object is captured, the surface having a first circle and a first handwritten character drawn on the surface;
- detecting a first ellipse corresponding to the first circle from the first image, and generating a registration image in which the first image is applied with projective transformation such that the first ellipse becomes a circle;
- and
- writing the registration image into a memory as data for determining sameness of the registration target object.
A non-transitory computer-readable medium storing a program comprising instructions for causing a computer to perform processing of:
- acquiring a first image in which a surface of a registration target object is captured, the surface having a first circle and a first handwritten character drawn on the surface;
- detecting a first ellipse corresponding to the first circle from the first image, and generating a registration image in which the first image is applied with projective transformation such that the first ellipse becomes a circle;
- and
- writing the registration image into a memory as data for determining sameness of the registration target object.
