Abstract: There are provided a method and a system for CCTV radial distortion estimation with low-complexity. An image distortion estimation method according to an embodiment includes: adding a certain distortion to an inputted image; detecting outlines from the image to which the distortion is added; detecting straight lines from the detected outlines; calculating a sum of the detected straight lines; performing the above operations N times, and determining parameters of an objective function by fitting an ‘objective function resulting from modeling of a sum of detected straight lines caused by an added distortion’ to the N distortions and the N sums; and estimating a distortion on the image by using the objective function the parameters of which are determined.

Abstract: A reliable receptacle connector and method of manufacturing thereof. The connector includes a terminal assembly having conductive elements held by a housing. Each conductive element has a mating end held by a housing tongue, a tail end extending outside the housing, and an intermediate portion partially held by portions of the housing that have different contours. The terminal assembly can be formed by assembling terminal subassemblies on opposite sides of a shield and molding over the assembly to form the housing. An inner shell is sleeved on the housing and engages with both portions of the housing that have different contours. A main shell is sleeved on the inner shell. An outer shell is sleeved on the main shell and shaped such that a seal can be formed between the shells. Such a configuration enables distributing forces to mate/unmate the connector from the shells to the housing and therefore reduces relevant movements between the components of the connector.
