3D scanners

JMP has the necessary tools and skills to perform 3D scanners of your products, and thus be able to provide you with 3D models, whether your requests are in the lock sector or not.

We can also take the process further, by reproducing your parts (within the limit of a certain size) using our 3D printer, and ending with the foundry section which allows us to reproduce your part in the desired material (bronze , stainless steel, etc ...)

A three-dimensional scanner is a device that analyzes objects or their close environment to collect precise information on the shape and possibly on the appearance (color, texture, etc.) of these. The data thus collected can then be used to construct three-dimensional synthetic images (digital objects) for various purposes.

Various technologies can be used in 3D image object scanning; each has its limitations, advantages and costs. However, certain types of objects are still difficult to digitize: for example devices using optical technologies encounter many difficulties with shiny, shimmering or transparent objects.

A 3D scanner generally measures the positioning of a sample of points in a coordinate system - a cloud of points - of the surface of a subject and then extrapolates the shape from their distribution: this process is called a 3D reconstruction. . If the color of each point is analyzed, then that of the surface can also be reconstructed.

Analogies exist between a camera and a 3D scanner. Both have a field of view and cannot see what is obscured, both technologies being optical. If the first captures the colors of the surfaces in its field the other measures its relative positioning with respect to a sample of points of the surfaces.

The image produced is based on a series of data composed of the coordinates positioning each of the sampled points with respect to the 3D scanner. If a spherical coordinate system is used and the scanner is its origin, then each point can be identified by coordinates (r, φ, θ). r represents the distance from the scanner to the point. φ and θ are the angles formed between the line going from the origin to the point analyzed in two planes passing through the origin, one horizontal and the other vertical. These spherical coordinates make it possible to locate each of the points in space in relation to the scanner, a preliminary and necessary work for the digital modeling of the three-dimensional image of the object.

Usually, the data (coordinates of points) collected with a single pass is not sufficient to fully model a subject. The work has to be done many times, even hundreds of times, from different points of view. All data collected must be reinterpreted and located in a single coordinate system and grouped together. The process, using the different measurements before being reinterpreted until modeling is known as (en) 3D scanning pipeline.
