The Speed of Color: Reducing Time for Color Scans by Adding i-Star Camera to the Toolbox

By November 10, 2017News

Time spent in the field and the quality of our product are two success factors that Truescan3D takes great consideration of on every project. The quality of the work that Truescan3D produces is critical to everything we do. Providing accurate information in a format that’s easy for our clients to use is always our #1 goal.  We focus on providing deliverables in a timely manner that adds value to our client. The more efficiently we can work in the field, the more we can increase that value proposition.

The P-40 scanner that Truescan3D uses is one of the most reliable and accurate scanners on the market. It can collect over 1,000,000 points per second and has a range of over 200 meters. This scanner can generally perform an intensity scan in around 3-4 minutes. One drawback is that it can take much longer to do color scans with the P-40 device. In some cases, it can take up to 15 minutes to do a color scan with the P-40. This can add additional field time over the course of a day or a project, thus decreasing efficiency. Using the i-Star camera, Truescan3D can now perform color scans by doing an intensity scan with the P-40 scanner and supplementing this with 360-degree color imagery from the i-Star camera shot at the exact scan locations. This allows us to reduce our scan times to around 5 minutes each and provide higher quality color imagery than is available with the P-40 scanner alone. By using this combination in the field, we’ve seen our productivity for color scans increase from around 40 per day to over 100 in some cases. The increased efficiency and higher quality is a win – win scenario for Truescan3D’s clients!

In addition to becoming more efficient in the field, the i-Star camera has provided Truescan3D with other opportunities as well. It has also allowed us to provide a “lower level” of visual documentation of a building or space where the accuracy of laser scanning might not be needed. Using the panoramic camera, we can move through a space and visually document it very quickly as if you were simply photographing the space with a camera. All the panoramic images can be tied together (much like registering a point cloud) to allow the user to move from image to image and see the space in a 360-degree view. This is great for a project where the user might not need to measure the space, but just wants to see and understand its features in great visual detail. This can be done very quickly and at a fraction of the cost of scanning.

With the continual evolution of equipment and software available for reality capture, it is imperative that service providers like Truescan3D always look for ways to become more efficient and serve their clients better. Stay tuned for other technologies we’re considering to become more efficient for our clients over the coming months.
