Abstract
The invention provides a kind of talking pen system of automatic identification of Chinese characters based on monocular vision, talking pen is provided with monocular cam, CPU connection monocular cam, switch element, memory and player；The feature database of magnanimity word is previously stored with memory；After switch element is opened, monocular cam carries out image typing, and CPU is sharpened processing to image；Then data skew recovery is carried out to the image array after Edge contrast；Feature extraction is carried out to the image array after recovery again, while the effective ratio of characteristic component is calculated according to the resolution information of monocular cam；When effective ratio is less than threshold value, identification abnormal information is prompted；When effective ratio is more than or equal to threshold value, the feature database in memory storage is compared, obtains final recognition result, and pass through player voice output.Monocular vision and mode identification technology are combined by the present invention, it is not necessary to which word can be identified in advance by making marks, and the word of anywhere can be identified.
Description
Technical field
The invention belongs to monocular vision, mode identification technology, in particular it relates to which a kind of point based on monocular vision is read
System of automatic identification of Chinese characters.
Background technology
Existing talking pen typically carries out Text region using modes such as bar code, RFID, i.e., is placed in advance under Chinese character
Identify label or place that naked eyes are invisible or visible identification code by Chinese character, when talking pen recognizes the preset identifications,
Chinese character can be recognized.
Following defect be present in above-mentioned existing talking pen：
(1) word identified in advance can only be identified；
(2) to not having tagged Chinese character None- identified；
(3) anywhere Chinese character can not be identified.
The content of the invention
Can not have tagged Chinese character to know anywhere the technical problem to be solved in the present invention is to provide a kind of
Other talking pen system of automatic identification of Chinese characters.
In order to solve the above-mentioned technical problem, the technical scheme is that providing a kind of talking pen text based on monocular vision
Word automatic recognition system, it is characterised in that：Including talking pen, talking pen is provided with monocular cam, in monocular cam connection
Central Processing Unit, CPU connecting valve unit, memory and player；
The feature database of magnanimity word is previously stored with memory；
After switch element is opened, monocular cam carries out image typing to target area, and transmits to central processing list
Member；
CPU receives described image, and processing is sharpened to image；Then to the image after Edge contrast
Matrix carries out data skew recovery；Feature extraction is carried out to the image array after recovery again, while according to point of monocular cam
Resolution information calculates the effective ratio of characteristic component；When effective ratio is less than threshold value, identification abnormal information is prompted；When effective ratio is more than
During equal to threshold value, the feature database in memory memory storage is compared, obtains final recognition result, and pass through player voice output.
Preferably, the monocular cam is at the nib of talking pen.
Preferably, the memory is a storage chip.
The word in target area is captured by the monocular cam on talking pen by the present invention and feature
Extraction, is compared with the condition code in database to the feature of extraction, carries out the Chinese character in output target area.
System provided by the invention overcomes the deficiencies in the prior art, and monocular vision and mode identification technology are combined,
Need not make marks in advance can identify word, and the word of anywhere can be identified；System architecture is simple, operation side
Just, reliability is high, and cost is low, can carry out volume production, suitably promote the use of on a large scale.
Brief description of the drawings
Fig. 1 is the talking pen system of automatic identification of Chinese characters schematic diagram based on monocular vision that the present embodiment provides.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.
Fig. 1 is the talking pen system of automatic identification of Chinese characters schematic diagram based on monocular vision that the present embodiment provides, described
Talking pen system of automatic identification of Chinese characters based on monocular vision includes talking pen, and monocular cam is housed at the nib of talking pen,
Monocular cam connects CPU, CPU connecting valve unit, memory and player.
The feature database of magnanimity word is previously stored with memory.
After switch element is opened, monocular cam carries out image typing to target area, and transmits to central processing list
Member；
CPU receives described image, and processing is sharpened to image；Then to the image after Edge contrast
Matrix carries out data skew recovery；Feature extraction is carried out to the image array after recovery again, while according to point of monocular cam
Resolution information calculates the effective ratio of characteristic component；When effective ratio is less than threshold value, identification abnormal information is prompted；When effective ratio is more than
During equal to threshold value, the feature database in memory storage is compared, obtains final recognition result, and pass through player voice output.
Wherein, memory is a storage chip.CPU is an intelligent chip.
The talking pen system of automatic identification of Chinese characters based on monocular vision that the present embodiment provides, monocular vision and pattern are known
Other technology is combined, it is not necessary to which word can be identified in advance by making marks, and the word of anywhere can be identified；System knot
Structure is simple, easy to operate, and reliability is high, and cost is low, can carry out volume production, suitably promote the use of on a large scale.
It is described above, only presently preferred embodiments of the present invention, it is not any to the present invention in form and substantial limitation,
It should be pointed out that for those skilled in the art, on the premise of the inventive method is not departed from, can also make
Some improvement and supplement, these are improved and supplement also should be regarded as protection scope of the present invention.All those skilled in the art,
Without departing from the spirit and scope of the present invention, when made using disclosed above technology contents it is a little more
Dynamic, modification and the equivalent variations developed, it is the equivalent embodiment of the present invention；Meanwhile all substantial technologicals pair according to the present invention
The variation, modification and evolution for any equivalent variations that above-described embodiment is made, still fall within the scope of technical scheme
It is interior.
