Topcon CR-H1 Handheld Capture

RTK-accurate reality capture made simple

The Topcon CR-H1 is a handheld reality capture solution that combines RTK GNSS accuracy, photogrammetry and augmented reality (AR) into a single, easy-to-use workflow.

Designed for construction, surveying and engineering teams, the CR-H1 allows anyone – not just surveyors – to capture accurate point clouds and 3D data quickly and efficiently, using familiar mobile-based tools.

Accurate 3D capture without complexity

The CR-H1 delivers centimetre-level accuracy point clouds by combining:

Topcon HiPer CR GNSS technology

RTK corrections via Topnet Live or compatible services

PIX4Dcatch mobile photogrammetry on an iPhone Pro / Pro Max

PIX4Dcloud for processing, sharing and analysis

This integrated approach removes the barriers traditionally associated with 3D capture, making high-quality spatial data accessible to more people on site

Visualise designs in real time with AR

One of the CR-H1’s standout capabilities is real-time AR visualisation. Users can overlay digital designs directly onto the real world, helping teams:

Verify designs on site

Identify clashes or issues early

Communicate intent clearly with stakeholders

This reduces misunderstandings, rework and delays — particularly on complex or fast-moving projects

Portable, flexible and easy to use

The CR-H1 is designed for everyday site use:

Lightweight, ergonomic handheld design

Mounted iPhone for intuitive data capture

Can also be mounted on a standard GNSS pole for precise single-point measurements

Fast setup with minimal training required

This flexibility allows teams to switch easily between handheld scanning and GNSS point measurement as required
