Three-dimensional radiograph security system
A method and apparatus for displaying a three-dimensional radiograph in a security scanner. A first X-ray image of an object is generated by the security scanner from a first viewpoint. A second X-ray image of the object is generated by the security scanner from a second viewpoint. The first X-ray image and the second X-ray image form a stereogram. The stereogram is displayed by the security scanner on a display system for the security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram. A parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of the object on the display system for the security scanner.
1. A method for displaying a three-dimensional radiograph in a security scanner, the method comprising:
generating, by the security scanner, a first X-ray image of a plurality of objects from a first viewpoint;
generating, by the security scanner, a second X-ray image of the plurality of objects from a second viewpoint, wherein the first X-ray image and the second X-ray image form a stereogram;
displaying, by the security scanner, the stereogram on a display system for the security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram, wherein a parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of an object of the plurality of objects on the display system for the security scanner;
determining an area of interest in the stereogram unaided by an operator, the area of interest in the stereogram including the three-dimensional visualization of the object;
performing object recognition on the object, the object located in the area of interest; and
generating an alert when the object is identified as a prohibited object, wherein the alert comprises a graphical indicator displayed in association with the object to draw attention to the object.
2. The method of claim 1 , wherein the alert further comprises an audible alert.
3. The method of claim 1 , wherein a structure of an interior of the object is seen in the stereogram.
4. The method of claim 1 , wherein a group of objects is located inside of the object.
5. The method of claim 1 , wherein the object is located inside of another object.
6. The method of claim 1 , wherein the display system is selected from at least one of a head-mounted display, video eyeglasses, a display screen, or smartglasses.
7. The method of claim 1 , wherein the parallax is such that the viewer perceives distance and depth in the stereogram.
8. The method of claim 1 , wherein the security scanner is located in a location selected from one of an airport, a courthouse, a stadium, and an office building.
9. A security scanner comprising:
a display system; and
a controller in communication with the display system, wherein the controller is configured to control an X-ray source and a sensor system to generate a first X-ray image of a plurality of objects from a first viewpoint; control the X-ray source and the sensor system to generate a second X-ray image of the plurality of objects from a second viewpoint in which the first X-ray image and the second X-ray image form a stereogram; display the stereogram on the display system for the security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram, wherein a parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of an object of the plurality of objects on the display system for the security scanner; determine an area of interest in the stereogram unaided by an operator, the area of interest in the stereogram including the three-dimensional visualization of the object; perform object recognition on the object, the object located in the area of interest; and generate an alert when the object is identified as a prohibited object, wherein the alert comprises a graphical indicator displayed in association with the object to draw attention to the object.
10. The security scanner of claim 9 , wherein the alert further comprises an audible alert.
11. The security scanner of claim 9 , wherein a structure of an interior of the object is seen in the stereogram.
12. The security scanner of claim 9 , wherein a group of objects is located inside of the object.
13. The security scanner of claim 9 , wherein the object is located inside of another object.
14. The security scanner of claim 9 , wherein the display system is selected from at least one of a head-mounted display, video eyeglasses, a display screen, or smartglasses.
15. The security scanner of claim 9 , wherein the parallax is such that the viewer perceives distance and depth in the stereogram.
16. The security scanner of claim 9 , wherein the security scanner is located in a location selected from one of an airport, a courthouse, a stadium, and an office building.
17. A three-dimensional security scanner comprising:
an X-ray source configured to emit X-rays toward a plurality of objects;
a sensor system configured to detect the X-rays;
a display system; and
a controller in communication with the X-ray source, sensor system, and display system, wherein the controller is configured to control the X-ray source and the sensor system to generate a first X-ray image of the plurality of objects from a first viewpoint; control the X-ray source and the sensor system to generate a second X-ray image of the plurality of objects from a second viewpoint in which the first X-ray image and the second X-ray image form a stereogram; display the stereogram on the display system for the three-dimensional security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram, wherein a parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of an object of the plurality of objects on the display system for the three-dimensional security scanner; determining an area of interest in the stereogram unaided by an operator, the area of interest in the stereogram including the three-dimensional visualization of the object; perform object recognition on the object, the object located in the area of interest; and generate an alert when the object is identified as a prohibited object, wherein the alert comprises a graphical indicator displayed in association with the object to draw attention to the object.
