Abstract
According to one embodiment, a reading system includes an extractor, a generator, a corrector, and a reader. The extractor extracts a first candidate region from an input image. The first candidate region is of a candidate of a region in which a meter is imaged. The generator generates a rectangle around the first candidate region when an exterior form of the first candidate region is circular. The rectangle corresponds to the exterior form of the first candidate region. The corrector generates a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle. The reader reads, from the second candidate region, a numerical value indicated by the meter.
Claims17
A reading system, comprising:
- an extractor extracting a first candidate region from an input image, the first candidate region being of a candidate of a region in which a meter is imaged;
- a generator generating a rectangle around the first candidate region when an exterior form of the first candidate region is circular, the rectangle corresponding to the exterior form of the first candidate region;
- a corrector generating a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle;
- and
- a reader reading, from the second candidate region, a numerical value indicated by the meter.
A reading method, comprising:
- extracting a first candidate region from an input image, the first candidate region being of a candidate of a region in which a meter is imaged;
- generating a rectangle around the first candidate region when an exterior form of the first candidate region is circular, the rectangle corresponding to the exterior form of the first candidate region;
- generating a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle;
- and
- reading, from the second candidate region, a numerical value indicated by the meter.
A non-transitory storage medium storing a program,
- the program causing a computer to:
- extract a first candidate region from an input image, the first candidate region being of a candidate of a region in which a meter is imaged;
- generate a rectangle around the first candidate region when an exterior form of the first candidate region is circular, the rectangle corresponding to the exterior form of the first candidate region;
- generating a second candidate region by using the generated rectangle to correct the exterior form of the first candidate region to approach a perfect circle;
- and
- reading, from the second candidate region, a numerical value indicated by the meter.
