As the “machine replacing human” trend accelerates, machine vision plays an increasingly vital role as the essential “eyes” of intelligent robotics. Vizum, a recognized innovator in stereo vision, continues to explore the frontiers of binocular 3D vision. At the 15th China (Beijing) International Machine Vision Exhibition (VisionChina 2018), Vizum officially launched its latest stereo intelligent vision product: the ViEye Line Laser Stereo Camera. This new product is designed to address key limitations in robot perception, including low intelligence, poor flexibility, high complexity, and restricted application scenarios, with the goal of expanding the reach of 3D vision technology across industries.
In real-world applications, especially in high-speed and high-precision industrial environments, it is essential to detect and measure objects rapidly and accurately while transmitting actionable spatial data to robots. For instance, recognizing and analyzing fast-moving objects on conveyor belts requires fine resolution, high detection rates, and dense point clouds. At the same time, users demand easy installation, broad working ranges, compatibility with a wide variety of materials, and cost-effectiveness — features that are often lacking in existing commercial 3D vision cameras.
ViEye addresses these challenges by combining binocular stereo vision with line laser scanning technology, supporting both single-line and multi-line configurations. It enables high-precision, high-speed object detection even under complex conditions, such as disordered stacking, indistinct surface features, fine gaps, and irregular shapes. The system currently achieves scanning speeds of up to 50 stereo lines per second, with each line capturing 2,000 data points. Future iterations will reach scanning speeds of 1,000 to 2,000 stereo lines per second, allowing for rapid, high-precision 3D data collection. As an object passes through the laser scan, the system compiles a complete, high-resolution 3D point cloud of its external contours.
The ViEye Line Laser Stereo Camera is powered by Vizum’s proprietary Natural Learning® architecture and enhanced by its latest stereo vision algorithms. It demonstrates strong perceptual and cognitive capabilities, performing exceptionally well in cluttered or low-texture environments and delivering precision down to 0.1 millimeters. This level of accuracy is sufficient for most high-end industrial applications where both speed and detail are critical.
Flexibility and ease of use are integral to the camera’s design. ViEye supports dynamic adjustment of its “interocular distance,” allowing users to switch lenses and configure setups based on specific needs. Its installation height can be freely adjusted to accommodate varying distances from target objects, with a working range from 30 millimeters to 2,000 millimeters. This makes it well-suited for customized and creative deployments in diverse industrial settings.
To accelerate adoption and integration, Vizum provides a robust software development kit that enables users to rapidly develop and deploy their own applications. The ViEye Line Laser Stereo Camera has already been successfully implemented in practical use cases such as shoe sole contour inspection and salt layer height detection.
Equipped with laser-line illumination and operating free from shadows, the system is resistant to ambient light interference. It functions effectively even in dim environments without the need for additional lighting, making it adaptable to harsh or challenging conditions.
The ViEye Line Laser Stereo Camera represents a significant leap forward in Vizum’s stereo vision product family. With its combination of high precision, intelligent functionality, adaptable deployment, and environmental resilience, it is poised to expand the role of stereo vision across the industrial landscape and unlock new intelligent application possibilities.
