Fig. 2 is a video input and output schematic diagram of the present invention.
Embodiment
Three colour imagery shots, an infrared camera are housed on the body of a motor car, and infrared camera is contained in the front portion of vehicle body, and three colour imagery shots are contained in the left and right and rear side of vehicle body respectively.Range radar, red infrared illumination light also are housed on the vehicle body.
Infrared camera is installed in interior rearview back or front bumper, and left and right camera is installed in respectively on the rearview mirror of the left and right sides, and the rear camera is installed in inside, car plate upper edge, back, or the rear bumper middle part.When camera is installed, can separate camera lens and image processing circuit plate, camera lens is contained in the outside, and figure strength reason circuit board is installed in concealed location.Three video acquisitions that colour imagery shot carries out comprehensive covering to the different visual angles direction, all there is the overlapping region at the visual angle of adjacent two cameras, and total overlay area of all cameras covers left and right, the rear region of car in the horizontal direction.
As shown in Figure 1, the signal output part of three colour imagery shots 1, infrared camera 2, range radar 3 meets controller U1, controller carries out the image splicing according to signal, by vehicle-carrying display screen 4 displayed image, controller external memorizer U2 is used to store the image after realtime graphic that camera obtains and via controller are handled.Controller is connected to form successively by A/D converter, dsp processor, D/A converter, and wherein dsp processor adopts dsp chip TMS320DM642.
High-speed video process chip TMS320DM642 is the high-performance processor that can not have the non-frame losing output image of compression in real time, and the combination of may command multichannel real-time video shows.The left and right sides camera of panoramic shooting head adopts 120 ° of wide-angles, rearview camera adopts 170 ° of wide-angles, Applied Digital image processing algorithm (removing the interlacing algorithm) is handled three road video images in real time, car body model in being pre-stored in processor carries out video-splicing to be handled, the edge merges, the realtime graphic compensation, particularly utilize edge detection algorithm that the same object with same edge bright spot is carried out fusion treatment, effectively avoided ghost phenomena, the image of (comprising ground) in two meters and the whole rear side scope about making the driver clearly see clearly around the vehicle body can be seen the blind area of tailstock left and right sides clearly.For the scene of obtaining the wide visual field of many pictures is represented, at the image that exists rotation and convergent-divergent to change, processor can adopt a kind of based on the image split-joint method of source coordinate to the target coordinate mapping, this method is amplified the define objective area image grid simulation earlier and is shunk with the non-integer parameter, imagination is carried out match with the grid that enlarges on source images, carry out the gray scale bilinear interpolation, then grid is retracted to the size of regulation, make that the rotation and the scale conversion of image is the two-dimension translational of image in the target coordinate space in the Cartesian coordinate space, source, by the source coordinate projection of target area is realized the splicing of image at last.
Dsp chip TMS320DM642 comprises the video port of 3 special uses, is used for receiving and handling video, can effectively improve the performance of whole system.As shown in Figure 2, provide 4 road composite video input interfaces, 1 tunnel 4 road composite video output interface.Wherein, night vision video and prospect video multiplex the 1 road video input interface.
Panorama shows:
Carry out effective capture by three colour imagery shots on the vehicle body, controller is handled image information, be shown on the vehicle-carrying display screen splicing the image that, make the driver clearly see the vehicle body image of two meters scopes interior (comprising ground) on every side clearly, particularly can see the blind area of tailstock left and right sides clearly.Simultaneously, the distance that object and vehicle body show in the automatically-calibrated image represents to warn distance by two equidistant frames around vehicle.
Control by controller, can also allow magnification region in the video in three orientation in the display screen show the image in one of them orientation, be implemented as follows: when playing the left steering lamp, then amplify the viewing area of left side video separately, pattern is looked on the right side and the backsight pattern is constant, three video windows big or small constant; When playing the right hand steering lamp, the viewing area of then amplifying the right side video separately, a left side look pattern and the backsight pattern is constant, three video windows big or small constant.
Night vision shows:
Body forward structure is equipped with two infrared light filling lamps, when specifically implementing, can be loaded on the next door of fog lamp.Each infrared light filling lamp is made up of six series connection infrared diodes, and collector lens is equipped with in the outside of each infrared diode, makes Infrared more concentrated.Be added with the logical filter glass of particular band that the copper aluminosilicate material is made before the whole light filling lamp, only allow the infrared light of 850nm～1100nm and fraction visible light to pass through, effectively suppress the influence of car opposite high light, efficiently solve glare problem.Two infrared light filling lamps can illuminate the invisible road surface of people's naked eyes, and the irradiation distance of light can reach 150 meters farthest.But naked eyes be cannot see at all, so can not cause dazzling to driver or the pedestrian who goes in the same direction.
Display mode:
Display mode is the single-image display mode, and display mode can switch between each display mode for panoramic image, night vision image or reversing image.When astern signal is input to controller, automatically switch to the reversing image display mode.
