Acquisition Control Features and Nodes

Acquisition control features in high-speed cameras from Emergent Vision Technologies support detailed management of image capture, critical for machine vision systems. They allow for precise adjustments in timing, exposure, and synchronization.

In the context of machine vision, where accurate timing and clear image quality are paramount, these features provide necessary control. Adjustments to trigger settings, exposure levels, and synchronization methods are key for applications involving fast-moving objects or precise measurement tasks. Compatibility with external time sources like precision time protocol (PTP) is also supported, facilitating seamless integration and synchronization within broader system architectures, essential for coordinated, high-speed image analysis and processing.

You can use the features with Emergent's eCapture Pro application. Alternatively, you can use the features with Emergent's eSDK API and the feature nodes. The \EVT\eSDK\Examples\EVT_AcquisitionControl directory contains example code that demonstrates how to programmatically use the acquisition control features.

Note: Each Emergent camera provides some or all of the following features and nodes, depending on the camera model.

Basic acquisition settings

The basic acquisition settings let you define basic parameters of image capture, including the mode (continuous or triggered), the speed of capture (frame rate), and the total number of images captured per session. These settings form the foundation for customizing image acquisition for different applications.

‍

Acquisition commands

The acquisition commands includes commands for starting and stopping the image capture process, giving you direct control over when data collection begins and ends. This capability is important for managing data collection efficiently and is fundamental to operating the camera within a larger system.

Triggering features

Triggering features control when and how the camera starts capturing images, allowing for both automatic and manual initiation based on external signals. This flexibility is crucial for applications requiring precise timing in image capture, such as capturing events or objects at specific moments.
