Leica RTC360 and Leica BLK360 Gen 1 (2018):

Leica RTC360:

In 2018, the adoption of the Leica RTC360 marked a significant advancement in Existing Conditions’ reality capture capabilities, significantly enhancing our scanning process and setting a new standard for efficiency and accuracy in the architectural, engineering, and construction industry. The Leica RTC360 offered advantages to our scanning process by eliminating the need for spherical targets and relying on cloud-to-cloud technology with feature recognition. This innovation significantly increased efficiency, specifically in environments with tight scheduling needs like hospitals and schools. Its speed substantially reduced our time in the field, with a simple greyscale scan completed in just 26 seconds, compared to three minutes with previous scanners.

The transition to Leica scanners required a setup of a centralized server and our Existing Conditions cloud to manage the large amounts of data efficiently. The Cyclone REGISTER 360 PLUS software of the Leica RTC360 outperformed previous scanners, generating cleaner data with millions of points, minimizing noise, and making a sharper image for us.

Lastly, the streamlined process managed through a tablet interface, has been more efficient by pre-registering scans on-site, reducing the risk of missing critical data points. Clients quickly recognized the benefits of the Leica RTC360's output, often preferring its data for their projects over that produced by previous scanners. Overall, the Leica scanners were a suitable choice for us due to the workflow and methodology for switching to them, and are also one of the most commonly used scanners to date.

Leica BLK360 Gen 1:

On the other hand, the first-generation Leica BLK360 scanners were marketed as a compact, user-friendly scanner for various professionals, including small architectural firms and interior designers. Existing Conditions initially deployed this scanner to get into small spaces, such as above-ceiling areas.

The Leica BLK360 G1 is also equipped with advanced features for comprehensive data capture. Its LiDAR sensor efficiently records 360,000 points per second to create 3D point clouds. Additionally, the integrated cameras enable the capture of 360-degree spherical HDR images, complete with thermal imaging capabilities. While the Leica BLK360 G1 was an easy-to-use tool, its early development limitations limited its efficiency.
