Abstract
The invention discloses the image recording system suitable for a variety of teaching environments, including：For two and the above follow shot equipment shot to teaching process；For establishing the base modules of the frame of reference using the lower left corner of benchmark capture apparatus shooting image as origin；Image for being shot to other follow shot equipment carries out coordinate transform to the conversion module of the frame of reference；For carrying out the adjusting module of radial distortion adjustment to the image after coordinate transforming；For catching the characteristic point of image after distortion adjusts, and stitching image causes the concatenation module that identical characteristic point overlaps in the image that different follow shot equipment are shot.The present invention is applied to the image recording system of a variety of teaching environments, even if classroom environment is different, it is not required that mobile device is debugged, but the image captured handled by above-mentioned steps, it is achieved thereby that the recording to whole teaching process, will not lack the beginning part.
Description
Technical field
The present invention relates to field of computer technology, and in particular to suitable for the image recording system of a variety of teaching environments.
Background technology
Teaching video recording class, exactly whole classroom instruction process is filmed by video recording equipments such as video cameras, objectively
Teaching process, the learning process of student and the teaching scene of classroom interactions of teacher is recorded, really reflects classroom teaching effect
Audiovisual digital file.Because Teaching video recording class can objectively reflect the overall process of classroom instruction, include the religion of teacher
Scientific principle is read, teaching ability, the content of courses of instruction, the teaching resource utilized, teacher to the tissue of teaching process, teachers and students it is bilateral
Interactive and caused teaching efficiency, thus refer to promoting outstanding classroom instruction experience, the research of progress curriculum reform, carrying out teaching
Lead, evaluate quality of instruction, organize teaching evaluation and establish teaching archive etc. and play increasing effect.
Differed yet with the size shape in various classrooms, so that existing teaching classroom video recording equipment is entering
Need to carry out substantial amounts of preposition adjustment work during row video recording, cause video recording can not completely record whole teaching process.
The content of the invention
The technical problems to be solved by the invention are that existing teaching classroom video recording equipment needs to carry out when being recorded a video
Substantial amounts of preposition adjustment work, video recording is caused can not completely to record whole teaching process, and it is an object of the present invention to provide suitable for a variety of
The image recording system of teaching environment, solves the above problems.
The present invention is achieved through the following technical solutions：
Suitable for the image recording system of a variety of teaching environments, including：For shot to teaching process two and
Above follow shot equipment；Described two and above follow shot equipment includes a benchmark capture apparatus；For being clapped with benchmark
The base modules of the frame of reference are established in the lower left corner for taking the photograph equipment shooting image for origin；For clapping other follow shot equipment
The image taken the photograph carries out coordinate transform to the conversion module of the frame of reference；For carrying out radial distortion to the image after coordinate transforming
The adjusting module of adjustment；For catching the characteristic point of image after distortion adjusts, and stitching image causes different follow shot equipment
The concatenation module that identical characteristic point overlaps in the image of shooting.
In the prior art, teaching classroom video recording equipment needs to carry out substantial amounts of preposition adjustment work when being recorded a video, and leads
Cause video recording can not completely record whole teaching process, so it can now be seen that many Teaching video recordings all lacked beginning portion
Point.During present invention application, teaching process is shot first with two and above follow shot equipment, by a follow shot
Capture apparatus on the basis of equipment setting, then the frame of reference is established as origin using the lower left corner of benchmark capture apparatus shooting image,
Then carrying out coordinate transform to the frame of reference, coordinate transform mentioned here to the image that other follow shot equipment are shot is
Finger fastens other image projections to reference coordinate, then carries out radial distortion adjustment to the image after coordinate transforming, reduces
Image fault caused by lens focus, the characteristic point of image after distortion adjustment is then caught, and stitching image causes different movements
Identical characteristic point overlaps in the image of capture apparatus shooting, so as to which the image mosaic for shooting two and above mobile device rises
To be molded.Due to being shot using multiple mobile devices, so even if classroom environment is different, it is not required that mobile device is entered
Row debugging, but the image captured is handled by above-mentioned steps, it is achieved thereby that the recording to whole teaching process,
The beginning part will not be lacked.
Further, present invention additionally comprises：For carrying out the balance module of color balance processing to spliced image.
Further, the frame of reference uses rectangular coordinate system.
Further, the follow shot equipment uses mobile phone.
Further, it is right when the concatenation module is additionally operable to that the distance between two characteristic points are different in both images
Image zoom in and out make it is identical to the distance between two characteristic points.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is applied to the image recording system of a variety of teaching environments, even if classroom environment is different, it is not required that to moving
Dynamic equipment is debugged, but the image captured is handled by above-mentioned steps, it is achieved thereby that to entirely imparting knowledge to students
The recording of journey, the beginning part will not be lacked.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding the embodiment of the present invention, forms one of the application
Point, do not form the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is present system structural representation.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment
As shown in figure 1, the present invention is applied to the image recording system of a variety of teaching environments, including：For to teaching process
Two and the above follow shot equipment shot；Described two and above follow shot equipment includes a benchmark shooting and set
It is standby；For establishing the base modules of the frame of reference using the lower left corner of benchmark capture apparatus shooting image as origin；For to it
The image of his follow shot equipment shooting carries out coordinate transform to the conversion module of the frame of reference；After to coordinate transforming
Image carries out the adjusting module of radial distortion adjustment；For catching the characteristic point of image after distortion adjusts, and stitching image causes
The concatenation module that identical characteristic point overlaps in the image of different follow shot equipment shootings.Present invention additionally comprises：For to spelling
Image after connecing carries out the balance module of color balance processing.The frame of reference uses rectangular coordinate system.The mobile bat
