The invention relates to a nuclear power station steam generator separation plate remote video inspection and measurement system, which comprises a far-end camera device able to realize imaging at different positions respectively and output of image signals, a signal transmission device receiving the image signals output by the far-end camera device, transforming the image signals into series signals and outputting the series signals, a superimposer for superimposing information on the series signals and then outputting the signals, a video capture card for receiving the information superimposed series signals, a monitor that is connected to the video capture card and used for displaying images, and a computer that is connected to the video capture card, performs calculation and measurement on a to-be-measured target and then outputs the result. The computer employs a binocular vision technology to calculate and measure the to-be-measured target. The system provided by the invention can realize visual inspection and accurate measurement on the separation plate after automatic penetrant inspection, and is suitable for the special environment of a nuclear power unit.
