Embodiment Construction

[0123] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0124] like figure 1 Shown, the ancient tomb inscription character recognition method based on hyperspectral remote sensing technology of the embodiment of the present invention, comprises the following steps:

[0125] Step 1. Obtain the hyperspectral image of the inscription. To perform hyperspectral processing on ancient tombstone inscriptions, image acquisition of inscriptions must be carried out first. In the process of image acquisition, there are two core points: partition and focus. Since ancient tombstones generally have a large area and a large range, it is impossible to obtain the enti...

Abstract

The invention discloses an ancient tomb inscription character recognition method based on a hyperspectral remote sensing technology, and the method comprises the steps: 1, sequentially obtaining the image data of an ancient tomb inscription through a hyperspectral instrument, and obtaining a plurality of hyperspectral images in each region; 2, preprocessing the hyperspectral image of the inscription; 3, selecting a spectral band to perform spectral processing on the hyperspectral image; 4, performing image enhancement on the inscription image after spectral processing; and 5, performing character recognition on the inscription image after image enhancement, performing similarity comparison with the inscription image to be recognized by utilizing a character image library, and outputting acharacter recognition result according to the similarity. According to the method, the characters of the inscription inscriptions in different environments can be recognized, good adaptability is achieved, the characters which cannot be recognized by naked eyes can be extracted, noise is smoothed while a picture containing the characters is enhanced, and the reliability, practicability and feasibility of the character recognition effect are good.

Description

technical field [0001] The invention relates to the field of character recognition for identification and protection of cultural relics, in particular to a method for character recognition of ancient tomb inscriptions based on hyperspectral remote sensing technology. Background technique [0002] China is an ancient civilization with a long history and has a large number of relics. How to effectively protect these relics is a major challenge for researchers today. As an important carrier of ancient text information, ancient tombstone inscriptions are a type of cultural relic with extremely high historical and artistic value. The common ways of degradation of ancient tombstones include various irreversible damages such as weathering and erosion, hollowing of cracks, and biological diseases, which may cause permanent loss of cultural relics information, and pose a great threat to the integrity of textual information of ancient tombstones and the value of cultural relics. [...
