One kind correction perspective distortion camera
Technical field
The present invention relates to a kind of camera, more particularly to a kind of correction perspective distortion camera.
Background technology
Photography is one of 19th century great invention of the mankind.Photography not only enables the vision of people extend, while it
Moment is turned into eternal, the hope that people want to allow the time to stop no longer passing is realized in a sense.It is born in photography
More than 170 years in development it is swift and violent, its development master includes the development of photosensitive material and the development of camera, derives film, electricity
Depending on, digital photography etc..By Modern Media, world civilization is set to progress into one " Map Reading Age ".The image culture epoch are
Development of human history is after the totem epoch.From August in 1839 19 days French science institute by the academy of sciences and fine arts institute hold it is joint
In meeting, L.J.M. daguerreotype photographies are disclosed to the whole world, indicate the birth of photography.Photography evolved is so far
Although achieving prominent achievement, but still it is difficult to solve the problems, such as subject perspective distortion.Correction perspective distortion is to space flight, army
Thing is taken pictures and measurement, and Architectural Photographing and criminal detection photograph etc. all have important value, and military affairs are taken pictures, and needs are real to record field
Scape, but the camera in modern times is difficult to solve this problem, and shooting point is big with photographic subjects deviation angle, its perspective during shooting
Deformation is bigger, because military surveillance not can be arbitrarily to arrive any scene to find optimal shooting angle, to reach the mesh of scouting
Often shooting angle deviate target, because perspective distortion is big, it is impossible to truly reflect that real scene brings difficulty to scouting;Punishment
The photo that shooting and producing goes out in thing photography can be used as a part for criminal suit evidence during criminal suit, it is necessary to objective,
But perspective distortion tends not to truly reflect reality, or even the severe photo of perspective distortion seems also to be altered truly, accurately,
Change or distort the doubt of reality;Automatic identification control is easy to hair when scene text image is obtained using equipment such as video cameras
The situation of raw perspective distortion, after deformation, these changes can all cause identification difficult, cause the overall performance of identification to decline, therefore
Need to carry out necessary correction to the image for deforming.Therefore a kind of correction perspective distortion camera is studied very necessary.
The content of the invention
