The DFK37AUX273 incorporates a high-performance 1/2.9-inch color CMOS sensor, delivering 1.6 megapixels of resolution (1440 x 1080 pixels). This megapixel count strikes an optimal balance, providing significantly more detail than sub-megapixel cameras while maintaining a high frame rate of 238 frames per second. The integration of a true global shutter is a defining feature, ensuring that color information is captured instantaneously across the entire sensor without the temporal skew inherent in rolling shutter designs.
Additional capabilities include programmable GPIOs for hardware triggering and strobe synchronization, which are essential for integrating the camera into automated production environments. Users have extensive software control over key imaging parameters such as exposure time, gain, and white balance, allowing precise adaptation to various lighting conditions and application needs.
A 1.6-megapixel color sensor, as found in the DFK37AUX273, provides substantial benefits for detailed inspection tasks. The increased pixel count allows the camera to resolve finer details, such as small scratches, color variations, or print defects that might be missed by lower-resolution cameras. This is particularly valuable in industries where product aesthetics or precise color matching are critical to quality.
The color global shutter technology in the DFK37AUX273 addresses a fundamental challenge in high-speed color imaging: color fidelity for moving objects. In a traditional rolling shutter color sensor, the red, green, and blue channels are captured at slightly different times as the sensor scans. If the object moves during this scan, colors can become misaligned, leading to artifacts like color fringing or smearing.
DFK37AUX273 แก้ปัญหานี้ด้วยเซ็นเซอร์ Global Shutter ที่เปิดรับแสงทุกพิกเซลและอ่านค่าทุกช่องสัญญาณสี (R, G, B) พร้อมกันทั่วทั้งเซ็นเซอร์ในเวลาเดียวกัน วิธีนี้ขจัดการเหลื่อมเวลาของข้อมูลสี โดยเฉพาะที่ขอบวัตถุเคลื่อนที่ ส่งผลให้ได้ภาพสีที่สมบูรณ์และเที่ยงตรง ซึ่งเป็นพื้นฐานที่จำเป็นสำหรับการวิเคราะห์สีอย่างแม่นยำในงานอัตโนมัติ
In electronics manufacturing, this camera excels at inspecting colored components, verifying solder paste quality (which can have color indications), and checking the integrity of colored markings on PCBs or chips. The combination of color information and high resolution allows for more sophisticated defect detection algorithms compared to monochrome systems.
สำหรับอุตสาหกรรมยานยนต์และชิ้นส่วน DFK37AUX273 สามารถใช้ตรวจสอบสีและสภาพของชิ้นส่วนพลาสติก สีของสายไฟ และคุณภาพของการเคลือบผิว ความสามารถในการจับภาพสีที่แม่นยำแม้ในวัตถุเคลื่อนที่ (ด้วย Global Shutter) ช่วยให้สามารถตรวจสอบชิ้นส่วนทุกชิ้นบนสายพานประกอบได้อย่างมีประสิทธิภาพ
Lighting is arguably the most critical aspect of a successful color vision system. For accurate color reproduction with the DFK37AUX273, a stable, uniform white LED light source with a high Color Rendering Index (CRI > 90) is essential. The light should provide consistent intensity and color temperature across the entire field of view. For imaging moving objects, a strobe light synchronized with the camera’s trigger input is recommended to freeze motion. Discover suitable lighting solutions and high-quality lenses for your application.
When compared to models from Hikrobot, the DFK37AUX273 often benefits from The Imaging Source’s deeper integration between hardware and software, resulting in a more polished user experience and reliable performance out of the box. While Basler and FLIR offer excellent cameras, the DFK37AUX273 frequently presents a more cost-effective solution for applications specifically requiring color global shutter performance at 1.6MP resolution.
