Abstract

A system and method for using images from a commodity camera for object scanning, reverse engineering, metrology, assembly, and analysis are disclosed. A particular embodiment includes a mobile imaging system to: enable a user to align an object to be analyzed on a turntable with a stencil; issue commands, by use of a data processor, to the turntable for automatic rotation of the turntable and the object thereon to a particular orientation for a camera of a mobile imaging device; capture a plurality of images of the object being analyzed at different automatic rotations of the turntable; upload the plurality of images of the object to a server via a network interface and a data network; and cause the server to generate a three dimensional (3D) model of the object from the plurality of images of the object.

Claims (28)

1. A system comprising:

a mobile imaging device having a data processor and a camera;

a network interface, in data communication with the data processor, for communication on a data network; and

a mobile imaging system, executable by the data processor, to:

enable a user to place an object to be analyzed adjacent to a calibration bar in view of the camera of the mobile imaging device;

issue commands, by use of the data processor, to the turntable for automatic rotation of cause a particular orientation for the camera of the mobile imaging device;

capture a plurality of images of external surfaces of the object being analyzed at different orientations;

automatically load a new stencil for each image capture;

upload the plurality of images of the object to a server via the network interface and the data network;

cause the server to generate a three dimensional (3D) model of the object from the plurality of images of the object;

cause the server to compare the 3D model of the object with a corresponding computer-aided design (CAD) geometry of the object;

cause the server to generate metrology information from the plurality of images and the 3D model of the object, the metrology information including information corresponding to deviations of the 3D model of the object from the corresponding CAD geometry of the object, the metrology information further including measurements of edges and surfaces of the object, object point scan data, CAD models, and object reverse engineering data generated from the object point scan data; and

cause the server to provide the metrology information to a user of a user platform via the data network.

2. The system of claim 1 wherein the plurality of images are extracted from a video.

3. The system of claim 1 wherein the metrology information further including information showing any deviation between scanned object dimensions and corresponding CAD model dimensions.

4. The system of claim 1 wherein the metrology information further including object assembly guidance and object analysis information.

5. The system of claim 1 wherein the mobile imaging device is a device of a type from the group consisting of: a personal computer (PC), a portable computing device, a mobile device, a laptop computer, a tablet computer, a personal digital assistant (PDA), a personal communication device, a cellular telephone, a smartphone, a wireless device, a network computer, and a consumer electronic device.

6. The system of claim 1 being further configured to analyze the plurality of images of the object for focus, lighting, and contrast.

7. The system of claim 1 being further configured to use an ArUco marker or other photogrammetric markers to facilitate alignment of the object.

8. The system of claim 1 being further configured to automatically adjust lighting in a metrology and analysis studio platform to properly illuminate the object for each image capture.

9. The system of claim 1 being further configured to capture the plurality of images of the object being analyzed at different automatic rotations of a turntable without user intervention.

10. The system of claim 1 being further configured to capture the plurality of images of the object being analyzed with a commodity camera.

11. The system of claim 1 being further configured to capture the plurality of images of the object being analyzed with a drone camera.

12. The system of claim 1 being further configured to capture the plurality of images of the object being analyzed with a robotic-arm based camera.

13. The system of claim 1 being further configured to use a colored screen to aid in isolating the object of interest from a cluttered background.

14. The system of claim 1 being further configured to provide real-time image quality or fitness assessments for object reconstruction.

15. The system of claim 1 being further configured to superimpose an image of a stencil on an image of an object for object alignment.

16. The system of claim 1 being further configured to superimpose an image of a stencil on an image of an object in an augmented reality or virtual reality environment for object alignment.
