Abstract
The invention relates to a non-splicing seamless panoramic real-time imaging device and an imaging method thereof. Ambient light is obtained by using a wide-angle lens; on the basis of cooperation of an image acquisition system with an image processing system, the ambient light is converted into an electronic image signal and then the electronic image signal is corrected and converted into displayable electronic image information; and then the electronic image information is displayed by a display system. Therefore, image acquisition and processing can be completed only by using one camera and one image chip. Meanwhile, no splicing is required during the processing process; the algorithm is simple; the response speed is fast; and the hardware performance requirement is low. Moreover, the wide-angle lens has a large view filed range; and imaging to a single image chip can be realized in a surrounding 360-degree range and an 80-degree range in a vertical direction. Most importantly, the output image does not need splicing processing and not splicing trace is left, so that clear and natural imaging is realized. The device and the method are worth popularizing in fields of parking and monitoring.

From the point of view of further coming with reference to imaging method provided by the present invention, employ following steps: first,
Obtain the ambient light of surrounding by wide-angle lens 1.During this period, wide-angle lens 1 collects about 360
The degree light of scope and the light of 80 degree of scopes of vertical direction, focus on image chip 10.Afterwards, rely on
In the participation of image capturing system 2, ambient light is converted into electronic image signal.Immediately, by image
The participation of processing system 3, electronic image signal is corrected and is converted into displayable electronic image information.In order to
Reduce subsequent processing steps, meet the needs of image viewing simultaneously, the rectification conversion process that the present invention adopts
Only need to convert through distortion correction and visual angle.Simultaneously it is contemplated that some use environments are more dark,
Affect follow-up display, gray scale regulation can be carried out to electronic image signal.Finally, by after above-mentioned process
Signal enters row format conversion, shows electronic image information by display system.Certainly it is contemplated that different
The decoding requirements of hardware are inconsistent, the form generating after the conversion of the form that is related to include avi, mkv, wmv,
mpg.Certainly it is not limited to above-mentioned form, as long as meeting the facility of reading and display is clear.
By above-mentioned character express and combine after accompanying drawing can be seen that using the present invention it is only necessary to one is taken the photograph
As head and an image chip can complete image acquisition and processing.Meanwhile, processing procedure need not be spliced, algorithm letter
Single, fast response time is low to hardware performance requirements.And, wide-angle lens angular field of view is big, about 360
Degree and 80 degree of ranged spaces of vertical direction all can be by imaging on single image chip.Even more important
It is that output image does not need splicing, no splices vestige, imaging clearly is natural.Apply in the field of parking
When, it is mountable to roof, nearby the become image of vehicle no substantially stretches phenomenon it is easy to observe.Furthermore, whole
Body manufactures low with maintenance cost it is easy to promote.
The above is only the preferred embodiment of the present invention, be not limited to the present invention it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Some improvement and modification can be made, these improve and modification also should be regarded as protection scope of the present invention.
