Ore Size Classification and Positioning System

System Overview

The Ore Size Sorting and Positioning System is built upon Vizum’s proprietary stereo vision technology, enabling high-precision 3D surface reconstruction of multiple types of ores in high-speed motion. The system performs real-time extraction and output of critical geometric parameters for each ore, including maximum length, width, height, integrated volume, and spatial coordinates on the conveyor belt. These outputs can be directly interfaced with automated classification units or high-pressure air-jet actuators to achieve high-throughput ore separation. Key technical advantages include support for concurrent multi-object measurement, wide field-of-view coverage, strong adaptability to harsh industrial environments, high configurability, and ease of system integration and deployment.

System Features

• Smart Terminal: Direct output of dimensional and point cloud coordinate data from the camera terminal—no need for an additional industrial control host.
• Simultaneous Multi-Ore Measurement: Supports synchronized measurement of hundreds of ore objects concurrently.
• High Real-Time Performance: Data acquisition, processing, and transmission latency is less than 10 ms.
• Supports High-Speed Motion: Delivers real-time processing at speeds up to 6 m/s with millimeter-level accuracy.
• Multiple Trigger Modes: Supports software trigger, pulse trigger, and level trigger for flexible deployment.
• High Accuracy: ±1 mm accuracy across 1-meter conveyor width; ±5 mm accuracy across 3-meter conveyor width.
• Wide Field of View: Single camera unit can measure widths up to 3 meters.
• Multi-Camera Stitching: For ultra-wide conveyors, multiple cameras can be mounted in parallel to extend the field of view.
• No Need to Modify Existing Setup: Installs directly above existing conveyor systems without requiring structural changes.
• One-Click Conveyor Baseline Calibration: Conveyor reference plane can be calibrated with a single operation.
• Strong Environmental Adaptability: Operates reliably in both indoor and outdoor settings, including low-light environments.
• Industrial-Grade Standard: IP65-rated protection, with data transmission via aviation-grade connectors and Gigabit Ethernet.

System Applications

The system is widely applicable to ore measurement and rapid sorting in fields such as metallic minerals, non-metallic minerals, and aggregates. It enables more refined and intelligent management of ore handling processes.
