摘要： A boundary protection method and system of a radiation detection robot. The boundary protection method comprises: a first laser radar and a second laser radar are arranged diagonally, a first marking rod and a second marking rod are arranged diagonally; a boundary of an interlocking zone is defined by the first laser radar, the second laser radar, the first marking rod and the second marking rod; the object to be detected is placed in the interlocking zone; the radiation detection robot uses rays to detect the object to be detected in the interlocking zone; an early warning zone is provided outside the interlocking zone; wherein when it is detected that a person or object has intruded into the interlocking zone, the radiation detection robot stops emitting rays; and when it is detected that a person or object has intruded into the early warning zone, a warning is issued directly.

摘要： A stereoscopic imaging system and method is disclosed. In one aspect the system includes an X-ray source that emits a plurality of X-ray fanbeams. The system includes columns of detectors. Each column of detectors is arranged at a preset angle with respect to the X-ray source. The detectors detect a strength of an X-ray fanbeam penetrating an object under inspection. The detectors form transmission images when the object intersects, or moves along a direction intersecting with, the X-ray fanbeams. The system includes a reconstruction apparatus that uses any two of the formed transmission images as a binocular image. The reconstruction apparatus calculates depth information of the object on the transmission images. The reconstruction apparatus superposes and fuses the calculated depth information to obtain 3D information. The reconstruction apparatus performs 3D reconstruction so that the detected object can be presented in a stereoscopic manner from different view angles.
