Along with the rapid progress of digital picture acquiring technology, digital image processing techniques, mode identification technology, the continuous decline of video appliances price, the continuous lifting of Computing ability, the enhancing of Intelligent Recognition and visual reproduction ability, some researchists have started to expect that application video capture technology is to realize bridge health monitoring problem.Although video capture technology can only be monitored the surface of bridge structure, its advantage having other monitoring technology to hardly match: cost is low, and easily carry out comprehensive monitoring, long term monitoring, reusability is high, intuitively shows, nondestructive measurement etc.Present video acquisition and mode identification technology are used widely in antitheft thief-proof, the field such as crime is pursued and captured an escaped prisoner of violation vehicle monitoring, express highway pavement health monitoring, bank.Photo-electric displacement measurement method now mainly comprises two kinds: laser projection formula and photoelectricity target formula.Laser projection formula ultimate principle: send laser by generating laser on measuring point, laser projects and forms hot spot on reference point curtain, and namely the change of facula position reflects that measuring point displacement changes.Its advantage measures directly (spot displacement change is measuring point displacement change), measuring accuracy is high, equipment manufacturing cost is cheap, shortcoming is also obvious, high to the stability requirement of laser instrument bearing, as deformed, loosen can affect greatly measurement, be generally applicable to displacement even variation and less tested structure.Photoelectricity target formula ultimate principle is that monitoring point change in displacement in the picture can be scaled monitoring point change in displacement, and its measurement range is comparatively wide, can accomplish self-calibration, but for video camera, the requirement of camera lens is higher, and cost comparatively laser type is high.These two kinds of modes are also many in the utilization of actual items.
Above two kinds of measuring methods can only measure two-dimension displacement, measurement for distance also cannot be measured, the major way of present photoelectric type measuring three-D displacement is binocular range finding, binocular range finding mainly realizes measuring point imaging by two cameras separated by a distance, the difference (parallax) that the lateral coordinates of measuring point imaging on the width view of left and right two directly exists and measuring point also exist inversely proportional relation to the distance Z of imaging plane: Z=fT/d, can converse the three-dimensional position of measuring point by geometric relationship.But binocular range finding transforms for world coordinates, demarcate and the status requirement of two video cameras higher, be applicable to change in displacement less, the measurement that distance is shorter, now also not comparatively successful story apply in actual bridge three-D displacement measure the item.
