NI PCI-1422 16-bit digital image acquisition card

NI PCI-1422 16-bit digital image acquisition card

Functional characteristics
High-resolution image acquisition: Supports 8-bit, 10-bit, 12-bit, 14-bit and 16-bit data acquisition, capable of meeting image acquisition tasks with different precision requirements. At a pixel clock rate of 40MHz, a acquisition rate of up to 80MB/s can be achieved, enabling high-speed, large-image, and high-resolution digital image capture.
Multiple camera interfaces: There are two versions, one compatible with digital cameras using RS422 signals, and the other compatible with digital cameras using LVDS (low-voltage differential signals). They can be connected to various types of digital cameras, adapting to different application scenarios and camera devices.
On-board memory: Equipped with 16MB or 32MB of on-board memory, it provides flexible image buffering for large image capture and continuous real-time data transmission, helping to avoid data loss or transmission bottlenecks.
Flexible triggering method: It provides 4 external TTL triggers, which can be used as high-speed digital input/output lines or trigger signals. Users can configure these trigger signals to precisely control the timing of image acquisition. It also supports the RTSI (Real-time System Interface) bus, enabling synchronization with other NI data acquisition and motion control devices to achieve more complex system integration.
Image preprocessing function: Equipped with a 64KB× 16-bit lookup table (LUT), it can be configured to perform conventional imaging programs such as data inversion, contrast enhancement, or other nonlinear transfer functions, to conduct real-time preprocessing of images during the acquisition process and improve image quality.

Application field
Industrial visual inspection: It is used for product appearance inspection, defect identification, size measurement, etc., helping enterprises achieve automated quality control and production process monitoring.
Scientific research: It is applicable to image acquisition and analysis in scientific experiments such as microscope imaging, high-speed photography, and astronomical observation, providing high-quality image data for researchers.
Machine vision system: As the core component of the machine vision system, it provides visual information for robots, automated production lines, etc., and realizes functions such as target positioning, posture recognition, and path planning.
