Accompanying drawing explanation
Fig. 1 is the structural representation of safe assisting system for automobiles based on single photographic head described in the utility model；
Fig. 2 is the structural representation of safe assisting system for automobiles based on single photographic head described in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, for meet a kind of safe assisting system for automobiles based on single photographic head of the present utility model, including:
Photographic head, is used for switching angular field of view, road information corresponding in gathering this angular field of view, and this road information is sent to imageing sensor.
Described imageing sensor, for road information changes into image information, and is sent to image processor by this image information.Described imageing sensor is preferably ccd image sensor.
Described image processor, for controlling the switching of photographic head angular field of view, image information corresponding in then obtaining this angular field of view, and according to needs of difference output image, this image information is carried out the adjustment of parameter, will output image transmission to display.Preferably, described image processor includes power subsystem, is used for providing voltage signal；Core controller unit, processes chip including data signal, for extracting the center point coordinate of target object from the image information gathered, carries out the conversion of space coordinates so that it is be suitable for the needs of difference output image.
Display, is arranged on automotive interior, for the image of display output in real time.
Further, as in figure 2 it is shown, the present embodiment also includes:
Central controller, for being sent to MCU single-chip microcomputer by operator information.
Described MCU single-chip microcomputer, is sent to described image processor for operator information is converted into corresponding instruction or code, and described image processor controls the switching of photographic head angular field of view according to this instruction or code.
