A client wants to use the camera for multiple purposes that meet specific parameters.
1. Viewing of Production tables that start 16' away from the camera and extend 16'. They want to maintain 40 PPF at a minumum (32') away from the camera. The width is 100+ feet.
2. They want to see the workers face so positioning of camera cannot be located high with a steep angle.
3. When viewing the production line they want it to appear as one long line, stiched view within the VMS.
4. At times they want to zoom in to see higher detail for training purposes but this is only required for certain segments of the production line.
Conditions: Interior application with general even lighting. There are large garage doors that open and close during the day that brings in sunlight, but they are far enough away to not cause shadows or bright spots. Temperature can get to 32 degrees inside building at worse case.
I chose the Samsung SND-7082 3 Mb camera model - Motorized vari-focal 3 to 8.5mm lens, Simple focus control - temp range 14-131 degrees F
This camera set at 78 degree AOV at a distance of 32' yield a Scene width of 51.8 and 40 PPF -- At same AOV but at a distance of 16' to the near side of the tables gave a width of 25.9' and 79.1 PPF. - Using the width dimension at the near side of the table I would place a camera approx 25' apart to achieve a horizontal view across all production tables. The cameras were place at 10' above the floor which gave a good facial details and able to see the conditons on the prodction tables.
Not sure if the VMS will let you stich images but at least I have the camera coverage.
Conditon 2 was to increase the detail to use for training purposes. It was aggreed upon the 70 ppf would be sufficent for training purposes. All that need to be done was to change the angle of view to 49 degrees and that would give a 70 ppf at a distance of 32' and scene view woudl be reduced to 29.2' at the outer edge of production tables. With the vari-focal being motorized and the bility to auto focus from the software gives the client what they are looking for.
First two examples show the calculator for condition 1 - 32' and 16' distance away from camera - 40 ppf minimum.
The second set of examples show the calculator to meet condition 2 - 32' and 16' distance from camera. 70 ppf minimum.
The calculator printouts made it easy to explain all this to the client.
