Abstract

Embodiments of a process comprising receiving one or more images in a buffer of a computer communicatively coupled to one or more cameras, retrieving the one or more images from the buffer, and storing the one or more images as one or more memory-mapped image files in a memory-mapped file (MMF) area of a memory that is shared by the computer and the one or more cameras.

Claims

1. A process comprising:

receiving one or more images in a buffer of a computer communicatively coupled to one or more cameras;

retrieving the one or more images from the buffer; and

storing the one or more images as one or more memory-mapped image files in a memory-mapped file (MMF) area of a memory that is shared by the computer and the one or more cameras.

2. The process of claim 1, further comprising running an analysis/inspection process on the one or more memory-mapped image files to extract vision data from the memory-mapped image file.

3. The process of claim 1, further comprising generating and/or receiving an indication that the memory-mapped image files are in the MMF area of memory.

4. The process of claim 1, further comprising pre-processing the one or more images retrieved from the buffer before storing them in the MMF memory.

5. The process of claim 4 wherein the one or more images include a plurality of related images and pre-processing includes stitching together the plurality of related images into a single stitched image.

6. The process of claim 5 wherein the single stitched image is stored as a single memory-mapped image file.

7. The process of claim 4 wherein the one or more images are unrelated and pre-processing includes adjusting image characteristics.

8. The process of claim 7 wherein the image characteristics include white balance, color balance, and gain.

9. A non-transitory computer-readable medium having instructions thereon that, when executed by one or more instances of a vision system running on a computer communicatively coupled to one or more cameras, cause the computer to:

receive one or more images in a buffer;

retrieve the one or more images from the buffer; and

store the one or more images as one or more memory-mapped image files in a memory-mapped file (MMF) area of a memory that is shared by the computer and the one or more cameras.

10. The computer-readable medium of claim 9 wherein the medium further includes instructions that cause the computer to run an analysis/inspection process on the one or more memory-mapped image files to extract vision data from the memory-mapped image file.

11. The computer-readable medium of claim 9 wherein the medium further includes instructions that cause the computer to generate and/or receive an indication that the memory-mapped image files are in the MMF area of memory.

12. The computer-readable medium of claim 9 wherein the medium further includes instructions that cause the computer to pre-process the one or more images retrieved from the buffer before storing them in the MMF memory.

13. The computer-readable medium of claim 12 wherein the one or more images include a plurality of related images and pre-processing includes stitching together the plurality of related images into a single stitched image.

14. The computer-readable medium of claim 13 wherein the single stitched image is stored as a single memory-mapped image file.

15. The computer-readable medium of claim 12 wherein the one or more images are unrelated and pre-processing includes adjusting image characteristics.

16. The computer-readable medium of claim 15 wherein the image characteristics include white balance, color balance, and gain.

17. An apparatus comprising:

a memory including a memory-mapped file area therein that is shared by the apparatus and one or more cameras;

a processor communicatively coupled to the memory;

one or more buffers communicatively coupled to the memory and to the processor and configured to be communicatively coupled with the one or more cameras; and

logic to cause the processor, the memory-mapped memory, and the buffers to;

receive one or more images in the one or more buffers,

retrieve the one or more images from the buffer, and

store the one or more images as one or more memory-mapped image files in the memory-mapped file (MMF) area of a memory that is shared by the apparatus and the one or more cameras.

18. The apparatus of claim 17 wherein the logic can further cause the computer to run an analysis/inspection process on the one or more memory-mapped image files to extract vision data from the memory-mapped image file.

19. The apparatus of claim 17 wherein the logic can further cause the computer to generate and/or receive an indication that the memory-mapped image files are in the MMF area of memory.

20. The apparatus of claim 17 wherein the logic can further cause the computer to pre-process the one or more images retrieved from the buffer before storing them in the MMF memory.

21. The apparatus of claim 20 wherein the one or more images include a plurality of related images and pre-processing includes stitching together the plurality of related images into a single stitched image.

22. The apparatus of claim 21 wherein the single stitched image is stored as a single memory-mapped image file.

23. The apparatus of claim 20 wherein the one or more images are unrelated and pre-processing includes adjusting image characteristics.

24. The apparatus of claim 23 wherein the image characteristics include white balance, color balance, and gain.
