Scanning a six-meter boat matrix in the field
DASCAN Laboratory specialists scanned the boat in difficult weather conditions using a Helix handheld 3D scanner.
Which is easier: send a six-meter heavy matrix of a boat to another city for scanning, or invite a specialist with a manual 3D scanner to your place? The customer decided the same way as you did, and invited the DASCAN Laboratory specialists directly to his facility.
The task was to accurately reproduce the shape of the existing matrix — the model was required for subsequent reverse engineering. For the convenience of scanning, the object was carefully placed outdoors, where the temperature had been around zero for a long time. During this time, the material shrank due to the cold.

High accuracy and detail are not important when scanning such an object.
Fortunately, the customer took this into account and warned in advance: the task is not to recreate the matrix in its original dimensions "one to one", but to accurately repeat its shape. Possible deviations from the original are not critical if all proportions are observed.
The scan was performed using a RangeVision Helix handheld 3D scanner. The brightness of the blue laser was enough to stop matting the surface. Data collection was further accelerated by reducing the resolution from 0.15 to 1 mm — there is no fine geometry on the matrix, and such detail was sufficient for the task. In addition, since the object is completely symmetrical, only half was scanned — with sufficient overlap for reliable binding. The second half was recreated with a mirror image.

Scanning plastic in the cold can give unexpected results.
To make sure that the material did not shrink further during the scanning process due to possible temperature fluctuations, individual areas were scanned twice — at the beginning and at the end of the work. The comparison showed that the sizes matched.
The whole process, including applying markers, took two hours.

A scan of half the boat is enough to recreate the shape.
Despite the "comfortable" conditions — night, a lantern and falling snow — when the equipment has to be warmed by hands and the optics protected from fogging, it was possible to obtain stable and complete data on the entire surface. After processing the point cloud, a ready-made 3D model was assembled, suitable for further reverse engineering.

With the Helix handheld laser scanner, such difficult tasks as scanning a black boat in the evening in the cold are solved quite simply. All you need is a supply of markers.
