Step 3: Run and preview the built-in segmentation application

After the SmartVision Engine application is installed, two sample applications are built-in by default [Application Example (Picture Acquisition)] and [Application Example (Segmentation)], allowing users to quickly experience the inference effect of smart cameras. A sample application is shown below:

Imaging parameter settings​

By adjusting the camera parameter settings, the optimal imaging effect can be achieved. As shown below:

[Trigger mode] is divided into two modes: "continuous trigger" and "IO trigger"

When the trigger mode of [ Continuous Trigger ] is selected, the configuration is automatically saved. After the operation is successful, the camera is automatically turned on, and the images captured by the camera are displayed in real time at the same time. This method supports updating camera parameters when the camera is open.

Click the [Capture Snapshot] button to take a photo of the currently visible real-time image, save it, and display it below. Turning on the [ Auto] button will automatically take pictures and save them according to the set interval, and display them below.

When the trigger method of [ IO trigger ] is selected, the configuration is automatically saved. After the operation is successful, the camera will be automatically turned on. In this mode, an external trigger signal needs to be connected. Once the external signal is received, the camera screen will be photographed, and the corresponding pictures and sampling numbers will be displayed below.

In the image acquisition interface bar, camera parameters can be set, including trigger settings and imaging parameter adjustments.

Basic parameter settings​

  • Trigger mode：When "IO trigger" is selected, "Edge setting" and "Trigger delay (us)" must be configured. "Edge setting" includes "rising edge" and "falling edge"; "Edge setting" must be configured. "Input Channel" is configured. "Input Channel" is divided into two channels: 1 and 2; the "Trigger Delay" and "Anti-shake" duration must be set. The "Trigger Delay" parameter defaults to 0ms, and the "Anti-Shake" parameter defaults to 5ms.
  • Exposure settings：When "Auto Exposure" is enabled, only "Exposure Compensation" can be edited; when "Custom" is enabled, "Exposure Duration" and "Exposure" parameters can be edited.
  • White balance settings：Not editable only when "Custom white balance" is enabled. It includes 7 white balance modes: "Incandescent", "Fluorescent", "Warm Fluorescent", "Daylight", "Cloudy", "Dusk" and "Shadow".

Advanced parameter settings​

  • Saturation: Adjusts the purity or vividness of colors in the image.
  • Contrast: Adjusts the difference between the lightest and darkest parts of the image.
  • Sharpness: Adjusts the clarity of image edges.
  • Custom White Balance: When enabled, you can adjust the Color Settings Mode, which includes Color Temperature and RGB Gain. If RGB Gain is selected, you can edit R Gain, G Gain, and B Gain.

Click Apply Parameters to save the changes. If the image does not look as good as the previous one, you can restore the previous settings by clicking Restore Parameters.

Snapshot images support One-click Export to Zip, One-click Delete, and Single File Delete. The system can store up to 200 snapshots, and when a new snapshot is taken, the oldest one is deleted automatically.
