HALCON 6.0 Frame Grabber Interface for Matrox Meteor-I Boards |
This page provides the documentation of the HALCON frame grabber interface HFGMeteor1.dll for the Matrox frame grabber board Meteor-I. Registered customers can download the latest revision of this interface from the MVTec WWW server. Please note that this interface currently supports only basic grabbing functions!
Revision: 2.0
System Requirements
- Intel compatible PC with Windows NT 4.0 (Service Pack 4).
- Successfully installed MATROX driver Meteor.sys.
-
Matrox DLLs mil.dll, milhost.dll, milmet.dll,
miltiff.dll, milvga.dll, and milvhook.dll.
These DLLs must be within your search path %PATH% (typically, they reside in the directory C:\Winnt\system32). If you do not have these DLLs, please contact Matrox or the vendor from which you bought the frame grabber board. Note that this interface was created based on the Matrox DLLs version 4.0. -
HALCON frame grabber interface HFGMeteor1.dll or
parHFGMeteor1.dll, respectively.
If you have properly installed the interface, both DLLs should reside in bin\i586-nt4 within the HALCON base directory %HALCONROOT% you have chosen during the installation of HALCON.
- One frame grabber board with one camera.
- Synchronous grabbing.
- Subsampling.
- Cropping arbitrary parts of an image.
- Only one frame grabber board with one camera.
- No asynchronous grabbing (grab_image_async not supported).
- No external trigger.
- grab_region() and grab_region_async() not supported.
- No LUTs.
Parameters for open_framegrabber():
| Name | 'Meteor1' | The name of the HALCON frame grabber interface. | |
| HorizontalResolution | 1, 2, 4, width | The desired image resolution. Use '1' for full resolution, '2' for subsampling by factor 2, '4' for subsampling by factor 4. Default: 1. | |
| VerticalResolution | 1, 2, 4, height | The desired image resolution. Use '1' for full resolution, '2' for subsampling by factor 2, '4' for subsampling by factor 4. Default: 1. | |
| ImageWidth | 0, width | The width of the desired image part ('0' stands for for the complete image). Default: 0. | |
| ImageHeight | 0, height | The height of the desired image part ('0' stands for for the complete image). Default: 0. | |
| StartRow | 0, row | The row coordinate of the upper left pixel within the desired image part ('0' obviously results in delivering the complete image). Default: 0. | |
| StartColumn | 0, column | The column coordinate of the upper left pixel within the desired image part ('0' obviously results in delivering the complete image). Default: 0. | |
| Field | --- | Ignored. | |
| BitsPerChannel | --- | Ignored. | |
| ColorSpace | 'gray', 'rgb' | Desired color space. Specifies the video input (together with the parameters CameraType and Port); please refer to the table below. Default: 'rgb'. | |
| Gain | --- | Ignored. | |
| ExternalTrigger | 'false' | External triggering is not supported. Default: 'false'. | |
| CameraType | 'ntsc', 'pal', see below |
The CameraType parameter is used to specify the video signal:
'ntsc' or 'pal'. Default: 'pal'. Furthermore, there exist 13 more values for the parameter CameraType corresponding to the MATROX MIL library; please refer to the table below. |
|
| Device | --- | Ignored. | |
| Port | 1, 2, 3 | Specifies the video input (together with the parameters BitsPerChannel and CameraType): '1' denotes the S-VHS jack, '2' the RCA (composite video) jack, and '3' the RGB (SUBD) jack; please see also the table below. Default: 1. | |
| LineIn | 1 | The desired input line (fixed). Default: 1. | |
Specify the video input by the following ColorSpace/CameraType/Port combinations:
| CameraType | ColorSpace | Port | Video Input | |
| 'm_rs170' | 'gray' | 2 | monochrome RS-170, 640x480, 12.5 MHZ, analog | |
| 'm_rs170_low' | 'gray' | 2 | monochrome RS-170, 512x480, 10.0 MHZ, analog | |
| 'm_ccir' | 'gray' | 2 | monochrome CCIR, 768x576, 14.8 MHZ, analog | |
| 'm_ntsc' | 'rgb' | 2 | color NTSC, 640x480, 12.5 MHZ, composite | |
| 'm_ntsc_rgb' | 'rgb' | 3 | color NTSC RGB, 640x480, 12.5 MHZ | |
| 'm_ntsc_yc' | 'rgb' | 1 | color NTSC Y/C (SVHS), 640x480, 12.5 MHZ | |
| 'm_ntsc_low' | 'rgb' | 2 | color NTSC, 512x480, 10.0 MHZ, composite | |
| 'm_ntsc_yc_low' | 'rgb' | 1 | color NTSC Y/C (SVHS), 512x480, 10.0 MHZ | |
| 'm_pal' | 'rgb' | 2 | color PAL I, 768x576, 14.8 MHZ, composite | |
| 'm_pal_rgb' | 'rgb' | 3 | color PAL I RGB, 768x576, 14.8 MHZ | |
