RIEGL VMQ-1HA High-Speed Single Scanner Mobile Mapping System
Price Available Upon Request
The RIEGL VMQ-1HA is a compact high-speed single-scanner mobile mapping system featuring an adjustable swivel plate for scanning at multiple angles. It provides a maximum range of up to 475 m, pulse repetition rates up to 1.8 MHz, 250 scan lines per second, 5 mm accuracy, 3 mm precision, a 360° field of view, and optional integration of up to four cameras.
Product Overview
The RIEGL VMQ-1HA is a compact, high-speed single-scanner mobile mapping system designed for a range of mobile mapping applications.
Its single-scanner configuration uses an innovative swivel plate, allowing the scanner angle to be adjusted within a project. This enables users to perform additional passes from different scanner orientations to help minimize scan shadows and improve coverage.
The system also supports optional camera integration, making it suitable for projects that require both LiDAR data and complementary imagery.
Key Features
- Laser pulse repetition rate up to 1.8 MHz
- Up to 250 scan lines per second
- Maximum range up to 475 m
- Laser Class 1 eye-safe operation
- 360° field of view
- Multiple target capability
- Optional integration of up to 4 cameras
- Single-scanner configuration with adjustable swivel plate
- Designed to support scanning from multiple angles within the same project
Swivel Plate Configuration
The VMQ-1HA uses an adjustable swivel plate that allows the scanner orientation to be changed between acquisition runs.
This makes it possible to perform multiple drive-throughs at different scanner angles, helping reduce scan shadows while retaining a single-scanner system configuration.
High-Speed Data Acquisition
The system supports a laser pulse repetition rate of up to 1.8 MHz and up to 250 scan lines per second.
The supplied technical data lists effective measurement rates ranging from 300 kHz to 1800 kHz, with range and target-detection performance varying according to the selected operating rate.
Technical Data Overview
| Specification | 300 kHz | 500 kHz | 1000 kHz | 1250 kHz | 1500 kHz | 1800 kHz |
|---|---|---|---|---|---|---|
| Effective Measurement Rate | 300 kHz | 500 kHz | 1000 kHz | 1250 kHz | 1500 kHz | 1800 kHz |
| Max. Range, Target Reflectivity (ρ ≥ 80%) | 475 m | 370 m | 235 m | 235 m | 235 m | 235 m |
| Max. Range, Target Reflectivity (ρ ≥ 10%) | 170 m | 130 m | 85 m | 85 m | 85 m | 85 m |
| Max. Number of Targets per Pulse | 15 | 15 | 9 | 7 | 5 | 4 |
| Accuracy / Precision | 5 mm / 3 mm | 5 mm / 3 mm | 5 mm / 3 mm | 5 mm / 3 mm | 5 mm / 3 mm | 5 mm / 3 mm |
Minimum Range
The supplied source specifies the minimum range according to pulse repetition rate:
- 1 m at PRR ≥ 1 MHz
- 1.2 m at PRR < 1 MHz
This means the minimum range depends on the selected PRR rather than being a single fixed value across all operating modes.
Performance
The RIEGL VMQ-1HA provides:
- 5 mm accuracy
- 3 mm precision
- Maximum range up to 475 m
- Laser pulse repetition rate up to 1.8 MHz
- Up to 250 scan lines per second
- Multiple target detection
At 300 kHz, the maximum specified range is 475 m for targets with reflectivity of ρ ≥ 80%. At higher measurement rates, the maximum range varies according to the selected configuration.
Camera Integration
The VMQ-1HA supports optional integration of up to four cameras.
This enables image acquisition to complement the LiDAR data and supports projects requiring combined spatial and visual documentation.
Main Applications
The RIEGL VMQ-1HA is intended for:
- Transportation Infrastructure Mapping
- Road Surface Measurements
- HD Mapping for Autonomous Vehicles
- City Modeling
- Rapid Capture of Construction Sites and Bulk Material
- As-Built Surveying
- GIS Mapping and Asset Management
- Surveying in Open-Pit Mining
