66 -- MOTION ANALYSIS SYSTEM SOL N00178-00-R-1037 DUE 051900 POC Karen Lenox, Contract Specialist or G. R. Vaughan, Contracting Officer on (540) 653-7478 WEB: NSWCDD Dahlgren Laboratory Procurement Division Homepage, http://www.nswc.navy.mil/supply. E-MAIL: Questions concerning the Modification to Synopsis/Solicitation, sd11@nswc.navy.mil. This synopsis serves as Amendment 0001 to combined Synopsis/Solicitation N00178-00-C-1037 (Submission Number 44998) which appeared in the Commerce Business Daily (CBD) on 01 May 2000. In response to questions submitted by vendors, the following clarifications are provided: QUESTION 1. Does "Digital image archiving" imply more than the possibility to store image sequences digitized from S-VHS or film on disk files? For instance, other image archiving functions would be automatic backup to tape, automatic CD-ROM exchanger with a database of which disks holds which files, indexing possibilities to be able to search for different types of data etc. What are your minimum requirements? ANSWER: No, in order to meet the Government's minimum requirements the system does not need to set up a database, just store the image sequences and the data from those sequences. QUESTION 2. User customizable templates could be interpreted two ways. 1) That software can recognize a contour once it has been attached duringthe tracking process 2) That the user can predefine a shape for subsequent use by the tracking software. Which is correct? ANSWER: The first interpretation is correct. QUESTION 3. Is the 16mm film scanner an option, or is the possibility to scan 35mm film on the 16mm film scanner an option. ANSWER: The 16mm film scanner is required. An option to the contract is to include a 35mm film scanner. QUESTION 4. Could you explain the connection between handling HG-TX and Hadland camera data and being compatible with "Image express software". Is the basic requirement to read and analyze HG-TX and Hadland camera image formats? Are there any additional compatibility requirements? Please note that the specification of the Image Express package is not freely available, especially not to competitors. Another possible interpretation of this clause is that you already have Image Express and need your new software to be able to interchange some kind(s) of files with the existing system. If so, please specify which file formats you require. ANSWER: A basic requirement is to read and analyze from these types of camera image formats. The other format requirements were also listed: 16mm film, 35mm film, SVHS video. QUESTION 5. We understand "software to convert 16mm split frames (digital images) to continuous non-split frame movie sequence" as the capability to handle film where the images are not arranged in a standard way compared to the original film format. Is this required if the scanner proposed allows any definition of height and position of each camera frame so that this function is not necessary, that is you never get images that need to be merged to form a "non-split movie sequence" ANSWER: The "split frame images" need to be "stand alone images". Each image is worth a specific amount of time, things are happening on each image which need to be included in the data, therefore they need to be seen as a single image instead of split images. For example, Fastax II cameras at 22,000 images per second. QUESTION 6. Is there a different capability required for 3D static point measurement that would not be available in doing a 3D analysis on a single frame? ANSWER: No. QUESTION 7. Does the "porcupine plot" require 3D analysis? ANSWER: Yes. QUESTION 8. The reference to pin registered film transport is an engineering spec rather than a performance spec. Can you define the registration requirements in inches? Is a pin registered film transport a requirement if the proposed solution gives a very accurately registered image while getting rid of the split-frame problem apparent in pin registered film transports. ANSWER: Each frame of the film is to be positioned in the exact position as the last frame (as close as mechanically possible) for converting to digital images, this will make viewing the "digital movie" most pleasing to the eye without much "film jumping". We use film with sprocket holes to the .3000 inch, it should be compatible with this film. As long as the split-frame images (from 22,000 images per second, film) aremade to be one continuous movie sequence with smooth image viewing it does not matter how they get there. QUESTION 9. We understand "multi-threaded format conversion" as the ability to upload camera images from the cameras over Ethernet and storing them on disk files as a background task while simultaneously utilizing the system for other purposes. Is this correct? ANSWER: Yes. QUESTION 10. We understand "user defined motion planes" as being able to calculate 3D from one camera given manually entered information about a plane in which the target moves. Is this correct? If so it would be helpful if you could define "offset and skewed planes" in this context. ANSWER: Use geometric calibrations to define 3D planes. QUESTION 11. We assume that the _3D_ automatic point detection does not include automatically associating points seen in several camera views, i.e. identifying which point in camera view A is the same target as a point seen in camera view B? Is this correct? ANSWER: After point selection in thefirst frame is made, remainder should automatically be tracked and associated thereafter. QUESTION 12. Could you describe the "automated bar coded data decoding" requirement? We see two plausible interpretations, which we outline below: a. Barcode could be a code imprinted on each calibration target used to identify it from image data. The physical coordinates of the target would then be retrieved from a database based on the barcode id. If this is the correct interpretation: Is this function to include automatically finding barcodes (and thus calibration targets) in the entire camera image. Are you sure that the image resolution is good enough to be able to read the barcode? b. The barcode is a code that runs at the edge of video images to encode time, and other data. Please specify which type of data you intend to use. ANSWER: "Barcode" should be interpreted as a code of information on the edge of video images to encode time and other data such as GPS positioning, azimuth and elevation type information. QUESTION 13. Does the auto detection function apply to quadrant targets and "user defined feature match points" or is it restricted to "positive and negative contrast points"? This question applies to the 2D and 3D cases. ANSWER: This applies to user defined feature match points as well as positive and negative contrast points, for both 2D and 3D. QUESTION 14. Are there time codes or other codes, which are to be decoded from film or video images? If so, please describe the type(s) of code. (one such code may be the code described under 12b above, if that assumption holds). ANSWER: Time code on the film is to be IRIG A or IRIG B, edge code on the video as described in question number 12. Posted 05/11/00 (W-SN453816). (0132)
