Iterative Object Localization Algorithm Using Visual Images with a Reference Coordinate

Parallel Projection Based Self Localization Method for Mobile Navigation Applications

“…Note that the zoom factor depends on the distance from the imaging device, as well as the distance from the axis of the lens. The calibration table for the zoom factor is constructed according to the distance from the imaging device and the distance from the axis of the lens at the interval of 0.3m (Park et al, 2008). Fig.…”

“…The difference between i x and i y contributes as Δi in the localization. However, (Park et al, 2008) shows that the projection error is compensated by using the parallel projection model if the height of a landmark is known. Since the height of a landmark can be known, the localization performance is not worsened in this case.…”

Compressed domain indexing of scalable H.264/SVC streams

“…Multi-view algorithms for estimating the object distance in the uncompressed pixel domain have been presented in [24,25]. Regarding single camera sequences, some pixel domain algorithms have been proposed by [26][27][28][29][30], where defocus [27,29] or object size [28] is the used depth indicator.…”

Self Localization Method Using Parallel Projection Model for Mobile Sensor in Navigation Applications

“…The difference between i x and i y contributes as ∆i in the localization. However, [27] shows that the projection error is compensated by using the parallel projection model if the height of a landmark is known. Since the height of a landmark can be known, the localization performance is not worsened in this case.…”
