A terahertz security check method and system may include: a terahertz scanning device collecting a terahertz original image of a human body under test, and sending the same to a central server that identifies the terahertz original image, and determines whether the human body under test carries an article. If so, the image is marked with the position of the article and sent to a monitoring terminal. The monitoring terminal correspondingly marking the position of the article on a pre-stored human body cartoon image, and displaying the terahertz original images before and after marking to monitoring personnel, so that the monitoring personnel determine whether the central server has an identification error; and if so, the monitoring terminal changing a marker on the human body cartoon image, and sending the changed cartoon image to a client of security check personnel for displaying.

In a method of operating a dimensioning system with a plurality of laser scanners, a processor controls the operations of the scanners and processes the scanner signals, and further with memory for storing data delivered by the processor, the data acquired by the dimensioning system in its regular mode of operation are used to construct a three-dimensional model of surface points of the object including spatial coordinates and image intensity for each surface point. The three-dimensional model is stored in the memory. Based on the three-dimensional model, two-dimensional images from any desired viewing angle that was exposed to the scanner rays can be produced on demand to document the appearance of the object at the time the scan was taken.
