Recipe
Recipes are made up of multiple sequences. There can only be 6 defined recipes on the LSS controller. Each
recipe has its own recipe settings.
Trigger
Typically, triggers are sent directly to a smart camera and light simultaneously; using the LSS, the trigger is sent
to the LSS controller. The LSS controller then sends outputs to the camera and light at the programmed
intervals. Timing Diagrams are available in Appendix C.
Raw Images
Images that are captured based on the settings of each frame. They are then compiled together in the camera
software to create enhanced output images,
sometimes referred to as “super images”
because of their unique
characteristics; e.g. photometric stereo (PMS) images.
Output Images
Images resulting from combining raw frame images into one final image. In the case of PMS, the 4 raw images
create two output images; one shape image and one texture image.
Principle of Operation
The LSS-2404 is a programmable device that can be used to create multiple types of images. It is configured
from a standard web browser and can store and execute arbitrarily complex lighting sequences for multi-shot
imaging. The architecture is flexible and consists of recipes, sequences, and frames. Each frame corresponds to
one captured image and synchronous strobe output (light flash). Multiple frames together form a sequence and
each sequence results in an inspection image (output image). This output image can result from multiple images
merged via a computational imaging technique, or an image achieved with traditional lighting. Frames can have
their own settings per sequence. In addition, sequences can be set to repeat multiple times and every sequence
in a recipe can have different settings.
Multiple sequences combine to form a recipe. The recipe is the highest level of organization and can be thought
of as the instructions for creating a set of multi-shot and/or conventional images. Each recipe can have its own
global settings. The LSS-2404 can store up to 6 recipes in flash memory, but additional recipes can be created
and saved to the PC and loaded into the LSS-2404 when necessary.
When the LSS-2404 controller is powered up the last saved settings are loaded from internal flash memory. A
different recipe (i.e. configuration) can be uploaded from the PC via the LSS-2404 software if desired.
