Embodiment
Fig. 1 shows the synoptic diagram of file content immediately identifying of the present invention system.File content immediately identifying of the present invention system 10 comprises that mainly a document structure analysis device 121, reads flow process setting device 122, a location device 133 and a device for identifying 136.Have some characteristic in a structural file, for example, the paragraph in the English file or with the word of blank spaces etc.The present invention utilizes the characteristic of this structural file, and document structure analysis device 121 becomes several blocks with file mark, reads flow process setting device 122 and is provided with one and reads flow process to read these blocks of document structure analysis device 121 marks.Locating device 133 receives this that read that flow process setting device 122 is provided with and reads flow process.When this reads flow process when execution, the block that is reading locating device 133 location one.After locating device 133 was accomplished this block that is reading of location, this block that is reading of device for identifying 136 identifications was to export the content of this block that is reading.
Fig. 2 shows the process flow diagram of file content immediately identifying method of the present invention.Please be simultaneously with reference to figure 1 and Fig. 2.Be example with the English file of identification below, as embodiments of the invention.
At first, in step S202, whether vision detecting exists with follow-up mechanism 110 detecting files, if exist then confirm the position (step S204) of file.The position of file possibly change the position because of various factors, and at this moment, the vision detecting is searched file with follow-up mechanism 110 in a scope, if find this part file, then replaces the position of original record with new position.
In step S206, when the vision detecting detected file with follow-up mechanism 110, document structure analysis device 121 became block with each word or sign flag with blank spaces, and these blocks are commonly referred to as the word block at this.
In step S208, read flow process setting device 122 flow process that reads that reads by these word blocks of document structure analysis device 121 marks is set.One is the most simply read mode is that basipetal mode reads these word blocks according to right by a left side.
In step S230, according to step S208 set read flow process, locating device 133 is word for word done the action of location to these word blocks.Locating device 133 control one motor 144, with the camera lens of an image capture unit 145 facing to the next word block that will be read.The word block that the camera lens of image capture unit 145 faces representes that this word block is the word block in reading.Locating device 133 is all carried out same positioning step to each word block.
In step S232, the word block capture during image capture unit 145 reads each, the image of being obtained can be deposited into the file of various image formats, like the BMP image shelves of uncompressed, or the JPEG image shelves through compressing.Perhaps, with the image of the being obtained memory that writes direct.Because the resolution of considering to the image data of being obtained is too low, in this step, can amplify this word block in reading, obtain the image data of high-resolution, can solve the problem that is difficult for identification because of the composition pixel of word very little like this.
In step S236, the image data that image capture unit 145 is obtained is sent to device for identifying 136.Device for identifying 136 is with optical character identification (Optical Character Recognition; OCR) image data of this word block in reading of technological identification is then exported the content of this word block.The content of this word block of output can be the character code like ASCII (American Standard Code for Information Interchange), can directly be editor or convert other signal again at general PC.
In step S238, the content of this word block is converted into a voice signal through voice conversion device 137.
More than, if be provided with among the step S208 read flow process and accomplish the time, whether then step S202 detecting is got back to by system has another part file to exist.Otherwise, get back to step S230, continue to carry out location, capture, the identification of next word block.
Moreover locating device 133 also can be located a local block of the word block in reading, and for example, forms the character of this word.At this moment, image capture unit 145 is respectively to each character capture, each character of device for identifying 136 identifications.Afterwards, again with the synthetic word of the character group after the identification.
Fig. 3 shows a kind of example that is applied to the discrimination method of the English file of identification.The image of the word block of being obtained by step S230, S232 can carry out identification according to the following step.With word " robot " is example, at first confirms the target character position, the initial character " r " of word for example, and capture the image (step S356) of this character " r ".With the normalization of the image of this character " r ", that is, the image of acquisition character is adjusted into fixed size (step S358).Transfer the image of this character " r " to black-and-white image, this moment, the colour of each pixel was 0 or 1, that is binaryzation (step S360).Step S362 then captures the characteristic of the digital date after this binaryzation, is attached to the data bank of the sample character set of before being trained.Step S362, with the characteristic and the training sample character set of the character that is captured " r " compare, identification.If all characters " r ", " o ", " b ", " o ", and " t " all accomplish identification, then finish this word of identification, otherwise continue identification character late (step S368).Step S370 continues to confirm next target character position, like " o ".So, again with the synthetic word of the character group after the identification.
Be noted that, when in step S206, a structural file being done the block mark, can use plural architectural feature to carry out the mark of block.For example, can be divided into paragraph, ranks to English file, reach word, carry out the mark of block according to these three kinds of architectural features.Then, set the flow process that reads of these three kinds of structures, for example, read first word of first section first row earlier.
In addition, according to the present invention, except that above-mentioned be that block is the embodiment of identification with the word, be that the embodiment of block can implement equally with paragraph or ranks.
Among the present invention; More particularly; Image capture unit can use the low resolution PTZ video camera (Pan Tilt Zoom camera) that generally is used for video monitoring; This kind video camera can wide-angle rotates, tilts, focusing automatically, high magnification are amplified, and the demand of looking is carried fixing at one or the platform that moves on, be rich in motor-driven and independence.
