PIX4Dcatch with RTK officially certified by Bureau Veritas

The official certification by Bureau Veritas, recognized worldwide, is an important benchmark for confirming accuracy

This official recognition confirms that PIX4Dcatch with RTK is accurate enough to be used in industry. The Bureau Veritas found the workflow to have a margin of error of less than 5cm, which is twice the required accuracy for Class A measurements. They tested it for volume calculations as well as measurements for digitizing as-builts in a trench.

The Bureau Veritas is a company that specializes in testing, inspecting, and certification (TIC) across multiple industries, which it has been doing for 190 years and is highly regarded worldwide. The Pix4D workflow was submitted to them to be inspected and certified. The workflow is a mobile phone with the PIX4Dcatch app and an RTK device. When paired with the app PIX4Dcatch, the RTK device enables users to gather geotagged LiDAR and photogrammetry data for use in creating 3D models or single point measurements. These datasets can be processed in Pix4D software either online (via PIX4Dcloud) or on desktops (PIX4Dmapper, PIX4Dmatic, PIX4Dsurvey). The outputs are 3D site models that can be measured, analyzed, and shared.

Class A measurements require at least 10 centimeters accuracy, which means PIX4Dcatch with RTK is well within expected limits. For trench measurements, the PIX4Dcatch RTK workflow was confirmed by Bureau Veritas as accurate to within 5 centimeters and had a margin of error for volume calculations of less than 5%. Their certification said that the results were equivalent or superior to other surveying methods, namely with GPS or total stations. This means that a handheld, portable RTK rover is creating results with equal or better accuracy than cumbersome or older methods.

The RTK rover’s certification by a significant body like the Bureau Veritas is a significant achievement for Pix4D, who passionately believe this device has great potential in multiple industries, including construction and public works. With the certification from Bureau Veritas, PIX4Dcatch with an RTK device has been confirmed to be an accurate tool for terrestrial site scans to create 3D models and make single-point measurements.
