Description
Technical field
The utility model relates to digital calculator technical field, is specifically related to a kind of counter based on image recognition.
Background technology
Existing counter many employings keyboard is as input equipment, and only have mathematical computations function, usable range is narrower.In recent years, rapidly, the teaching of knowledge number and simple mathematical operation are that children early teach important component part in children's early education development.Counter has because having mathematical operation function and is applied to children and early teaches potentiality to be exploited.Traditional calculations device, because function is too single and it is interesting to lack, is difficult to the teaching purpose realizing teaching through lively activities, is not suitable for being directly used in children's early education.
Utility model content
Single and be unsuitable for children and early teach defect for existing calculator function, the utility model provides a kind of counter based on image recognition.
For solving above technical matters, the technical solution of the utility model is:
Based on a counter for image recognition, comprise input/output module, microprocessor and memory module.Input/output module comprises camera and touch-screen.The input end of the output termination microprocessor of camera, microprocessor and memory module two-way communication, memory module and touch-screen two-way communication.
Concrete, input/output module also comprises audio input device and audio output apparatus.Audio input device connects the input end of memory module, and audio output apparatus connects the output terminal of memory module.
Concrete, microprocessor is Toshiba TMPV7528XBG type image recognition processor, and memory module is SLC NandFlash.
The beneficial effects of the utility model: counter of the present utility model utilizes camera acquisition be loaded with the image of computing information and transfer to microprocessor, operation result is transferred to memory module after carrying out image recognition union by microprocessor, result of calculation is transferred to touch-screen display by memory module, realizes basic mathematical calculation function.Toshiba TMPV7528XBG type image recognition processor has two Cortex A9 cores and 6 Float Point Unit, can complete image recognition fast.Counter of the present utility model has audio input device and audio output apparatus, can realize the audio frequency input and output of computing information and result of calculation, expands its function and application scope.Counter based on image recognition of the present utility model has that volume is little, lightweight, stable performance, the feature such as easy to use, children's early education course can be expanded as required, there is larger popularizing application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, embodiment comprises input/output module, microprocessor and memory module.Input/output module comprises camera, touch-screen, audio input device and audio output apparatus.The input end of the output termination microprocessor of camera, microprocessor and memory module two-way communication, memory module and touch-screen two-way communication, audio input device connects the input end of memory module, and audio output apparatus connects the output terminal of memory module.
In the present embodiment, microprocessor is Toshiba TMPV7528XBG type image recognition processor, and memory module is SLC NandFlash.
During use, camera shooting is loaded with the card of numeral or sign of operation and picture signal is transferred to microprocessor, microprocessor carries out the feature extraction based on image recognition, obtain numeral to be calculated and sign of operation information, microprocessor calculates result of calculation and result of calculation is transferred to memory module, result of calculation is transferred to touch-screen display translation by memory module, can need, by audio output apparatus, result of calculation or relative nursery rhymes etc. are play output according to user.Except the shooting of use camera is to obtain except numeral to be calculated and sign of operation information, user is by the counter input calculating signal of audio input device to the present embodiment.The counter support of the present embodiment uses the dummy keyboard shown by touch-screen to input.It is more than the basic methods of the present embodiment.
The counter of the present embodiment can utilize microprocessor to write mathematical computations exercise question at random, mathematical computations exercise question transfers to touch-screen display through storage module, the card being loaded with result of calculation utilizes camera to take after calculating by children, result of calculation on microprocessor recognition image also judges that its correctness judges signal to export, and judges that signal is through storer and by touch-screen or audio output apparatus output.The counter of the present embodiment can calculate in one group of mathematical computations exercise question the quantity of the exercise question doing to or do wrong, and is exported by touch-screen or audio output apparatus.
Utilize the counter of the present embodiment can carry out children and know number training.Children select the card being loaded with numeral, and utilize camera to take card, the numerical information in microprocessor recognition image, numerical information transfers to touch-screen and audio output apparatus via memory module, the pronunciation of final output numeral or relative nursery rhymes.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
