Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing Give the preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to herein Described embodiment.On the contrary, the purpose for providing these embodiments is to make the understanding to the disclosure more saturating It is thorough comprehensive.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention The implication that technical staff is generally understood that is identical.Term used in the description of the invention herein is intended merely to description tool The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein " and/or " include one or more phases The arbitrary and all combination of the Listed Items of pass.
Referring to Fig. 1, the drive recorder of an embodiment, including：Controller 10, the storage being connected with the controller 10 Device 20, display device 30, the first image capture device 40 and the second image capture device 50.
The controller 10 includes：
Image collection module 110, for right from described first image collecting device 40, second image capture device 50 It should obtain while gather the first image and the second image for including public entities object.
It is to be appreciated that two image capture devices direction of advance that collection vehicle travels simultaneously in vehicle travel process The upper image information for including public entities object, is designated as the first image and the second image respectively.It is to be appreciated that including public reality Body object refers to that two images include identical entity object.
Image registration module 130, image registration is carried out for the first image to acquisition, the second image, is obtained The mapping relations of first image and the same pixel point of the second image of acquisition.
It should be noted that same pixel point refers to that a point on entity object correspondingly represents same in different images The pixel of individual point.The method of image registration can be accomplished in several ways, such as optical flow method, image block search matching etc..
Output module 150 is synthesized, for according to the mapping relations, the first image, the second image to acquisition to close Into obtaining composograph, and the composograph is exported to the display device 30 and the memory 20.
According to the mapping relations of the first image of acquisition and the same pixel point of the second image of acquisition, synthesis can be passed through Output module 150 is synthesized to obtain composograph to the first image of acquisition and the second image of acquisition.
After composograph is obtained, the composograph is exported to display device 30 to be shown, while export the conjunction Stored into image to memory 20, in this way, carrying out driving recording to the driving situation in vehicle travel process.In a tool In body embodiment, processing is first carried out to composograph and forms video data, then by video data storage into memory 20.
Described image acquisition module 110, described image registration module 130 and the synthesis output module 150 are by corresponding Burning or imprinting form after the program write-in controller 10.
