Embodiment
As shown in figure 12, the invention provides a kind of road and monitor panoramic picture processing and display packing, in this example, background is one section 3 track road and 4 motor vehicles, and the panoramic picture surveillance is provided with 3 outfield video cameras.May further comprise the steps:
Steps A), absorb the segmented image of roads by 3 monitoring arrangements;
Step B), each segmented image that steps A is obtained is by road axes direction extensional deformation;
Step C), with amalgamation and the demonstration in order of each segmented image behind the extensional deformation.
As shown in figure 13, above-mentioned steps A) may further comprise the steps:
Steps A 1), along road 3 monitoring arrangements are set continuously;
Steps A 2), each monitoring arrangement absorbs the different segmentations of road respectively and obtains each segmented image.
