This page summarizes the Acquire perspective of the Perception Studio program. Like the name suggests, the Acquire perspective gives you all tools and possibilities necessary for the acquisition of hyperspectral data from a hyperspectral camera.
About the Acquire Perspective
Read here about general information of this plug-in, about the arrangement of the GUI perspective and function categories of the ribbon menu.
In the Acquire perspective of the Perception Studio program you can
- connect to an interfaced hardware device (like a camera),
- record hyperspectral data cubes,
- append descriptive parameters,
- crop the data to ensure a reasonable data volume.
The following image is showing the Acquire perspective after recording a hand.
The ribbon on the top allows
- to select a device (like a camera),
- to control the acquisition (Record button and the Frame Count spin wheel)
- to control zoom options,
- to save an acquired cube
On the left side of the perspective the data's description panel is shown. Descriptive parameter are attached to the hyperspectral cube data and are useful for later reference. The descriptive parameters let you
- save or open a description template
- specify a title for the measurement
- specify sample related information like sample location, sample description, or images of the sample, etc.
- specify measurement related information like date of measurement, measurement system, measurement description, etc.
- specify further helpful information shown in the image above
The Acquisition Procedure
Connect to a Hardware Device
An interfaced hardware device (e.g. a camera) can be selected from the ribbon - located most left.
Be sure the hardware device is set up properly.
Please refer to the Setup a Hardware Device documentation for further information.
Record Hyperspectral Data
Click the Record button from the Acquisition section in the ribbon. Optionally change the frame count parameter beforehand.
The frame count parameter specifies the size of the hyperspectral cube to be recorded. Since a cube is composed over time, a large frame count number results in a long acquisition process and typically in a large data cube recorded.
Try to find the best working frame count parameter for your needs. In general it is good practice to keep this parameter adequately small.
Crop a Record
Typically a recorded scene contains a large portion of environmental information not of interest for further investigation. After acquisition crop a record to ensure reasonable data volumes. To do this, set the position of the greenish rectangle shown above to cover the region of interest in the scene.
Append Descriptive Parameters to the Record
When your are satisfied with the recorded data it is good practice to append descriptive parameters to the data set for later reference. The documentation area is shown on the left hand side of the recorded data.
Specify all entries of interest by editing the entries of the documentation table. At the bottom photographs of the samples, the measurement setup, etc. can be added to the selected data set.
After pressing the Save Data button the recorded data becomes available in other perspectives (like Explore or Model).
