Abstract
This invention relates to a digital camera with scanner function for automatic rectifying picture distortion, which adopts digital converter technique to rectify picture distortion directly inside the camera, exports picture with the same precision as scanner, and provides an effective facility for scanning large picture for general people and traveling. The invention enlarges the scope of scanning picture, for example scanning fresco.
Description
Technical field
The present invention relates to digital camera, particularly adopt the digital conversion technology, at the inner directly correction of photograph deformation of camera, the photo and the scanner of output have same precision, have the digital camera of scanner functions.Belong to International Classification of Patents G03817/00 " fuselage of camera parts or camera and annex thereof " technical field.
Background technology
Along with the development of digital photo technologies, the digital camera of high definition, high-performance, high resolving power (1,200 ten thousand pixel) dropped at present that ordinary people can bear below 4000 yuan.Take a picture, take literal and figure with such high-performance camera, can digital form preserve great mass of data.Because any camera is taken a picture all certain deformation (owing to machine error and assembly error, the distortion that each camera is taken a picture is different, at the relative position of camera and drawing and optical parametric not simultaneously, the deformation rule that same camera is taken a picture is also different), so can not be directly used in high-precision graph scanning.Be the generation of 2004100779074 patent of invention " camera imaging scanning method " along with the patent No., digital camera can be used for the high-precision graph scanning of large format.But need carry out digital conversion to the digital photos after taking pictures when adopting " camera imaging scanning method " to carry out graph scanning, this conversion has promptly increased by a procedure, influences work efficiency again.
Summary of the invention
Purpose of the present invention, be to overcome above-mentioned deficiency, provide a kind of according to will be in " camera imaging scanning method " of first to file the digital conversion technical cure of correction of photograph deformation in the graphic processor of digital camera, to produce the digital camera of automatic correction of photograph deformation.
Technical scheme of the present invention is as follows.
The present invention is made up of the digital camera and the test pattern of automatic correction of photograph deformation.
Described test pattern is made of the mark of arranging according to certain rules.The pattern of mark can be cross curve, circle, triangle, square etc., can be solid also can be hollow; Arrangement mode can be vertically and horizontally arranged, also can arrange the polar coordinates system as concentric circles and homocentric rays formation by other means; Arrangement pitches can be identical, also can be different.
The invention has the advantages that:
1, the present invention makes digital camera have the correction deformation ability, makes digital camera have the function of scanner, has increased the functions of use of digital camera.
2, the present invention makes in the application of first to file " camera imaging scanning method " more conveniently, and efficient is higher.
3, the present invention provides effective tool for ordinary people carries out the large format graph scanning.
4, the present invention provides effective tool for the graph scanning in the travelling.
5, the present invention has increased the scope that can carry out graph scanning, for example can scan mural painting.
Embodiment
Using method of the present invention is as follows:
(1) presses general camera during non-graph scanning and use, camera is made as common shelves;
(2) operation steps during the camera plane figure:
1. camera is made as the scanning shelves;
2. camera and test pattern are positioned over the position of mutual correspondence, test pattern is positioned at effective vision area of camera;
3. take test pattern,, can take several test patterns as required for support bracket fastened occasion is arranged.After taking test pattern, the software that solidifies in the camera calculates the deformation rule of each test pattern photo according to the image of test pattern;
4. photographic subjects figure, taking pictures of targeted graphical corrected distortion through the software of camera inside automatically according to the deformation rule of corresponding normal pictures, and the picture of correcting after the distortion is stored in the storage card of camera;
5. the photo of preserving in the camera is passed in the computing machine.
Claims (3)
1, a kind of digital camera of automatic correction of photograph deformation is characterized in that: the software of correction of photograph deformation is installed in camera, but makes the camera automatic correction of photograph deformation; The photo of output has identical geometric accuracy with scanner, and has scanner functions.
2, the digital camera of automatic correction of photograph deformation according to claim 1 is characterized in that: the software of described correction of photograph deformation is based on the distortion of correcting the targeted graphical photo according to the deformation rule of test pattern.
3, the digital camera of automatic correction of photograph deformation according to claim 1 is characterized in that: described test pattern is made of the mark of arranging according to certain rules; The pattern of this mark can be cross curve, circle, triangle, square, can for solid also can be for hollow; Its arrangement mode can be vertically and horizontally arranged, also can arrange the polar coordinates system as concentric circles and homocentric rays formation by other means; Arrangement pitches can be identical, also can be different.
