Projection Mapping Scanner

[Cristoforo Kanoy]

For many years we have approached projected images as simple 2 dimentional flat pieces, used predominantly to relay presentations in a hotel conference rooms. But with the emergence of powerful media servers, we now have the ability to use projection to transform plain objects into mind blowing visual art instalations through a process known as 3D Projection Mapping.

The laser scanner used to create the 3D map of your projection surface is a common tool used in the construction industry and, because the hardware is highly specialised and expensive, most AV companies will rely on a professional scanning company to provide this service and then construct the 3D model.

Your projection mapping specialist will convert the digital architectural drawing of the projection surface into a design format and then identify a position which will be used as the audience perspective reference. This is handed over to the content creators.

Turn your brightest ideas into outstanding visual experiences thanks to the largest and most complete library of visual effects on the market. There are more than 1,000 potential combinations, which leaves endless room for customizing your projection mapping. All the tests and changes you make are visible live. No rendering time to break the creativity. You build your show in a fluid and consistent way.

Launched in 2016, the Olga kit is now a reference for building settings for 3D projection mapping. The simplicity of use combined with the flawless quality of the product make it a best-seller among audiovisual professionals and artists around the world.

Solutions: The TruePoint 3D laser scan technician used a survey-grade P-20 Leica laser scanner to capture accurate data for projection mapping purposes. TruePoint captured the entirety of the front faade from ground level in less than twenty scans. The data was then registered and used to create a 3D Revit model from which a 3D Mesh model was exported for the client to analyze overall building dimensions.

Deliverable: TruePoint CAD engineers used the point cloud generated to develop a 3D mesh model (.obj file format) containing basic architectural elements including walls, roofing, openings, etc.

Added Value: The client asked for details on a statue and light posts in the plaza across the street. Laser scanners indiscriminately capture 360 degrees of information, allowing the TruePoint CAD engineer to go back and access this information for the client, even though it was outside of the original project scope.

*DISCLAIMER: 3D laser scanning is a measurement tool to assist in capturing as-built conditions of existing spaces and should be used in conjunction with other sound industry practices for verifying these conditions, including but not limited to: site visits, manual field measurements and verifications of scan data, to ensure its accuracy prior to design and engineering. Because this data can be used for various applications and disciplines outside the scope of the original field scanning and beyond our control, we cannot guarantee that the data is accurate for these uses.

Projection mapping is the art and science of projecting onto objects rather than a flat surface. Referred to as "projection mapping" or "video mapping." A stunning, almost "magical" appearance is the end result.

As a result, 3D projection mapping considers the shape and contours of your projected surface, unlike 2D projection mapping. Projection on flat surfaces like screens and walls is 2D, while 3D is projection on 3D objects. By warping content with software, 3D can produce mind-bending effects.

It has greater effects on object recognition and memory than 2D projection mapping. 3D project mapping systems outperform 2D project mapping systems in terms of long-term ROI. It is also much more expensive than 2D and takes much longer to create than 2D.

It's possible to use 2D mapping to create massive visual displays that span entire walls in your venue. On the other hand 3D projection can twist content with controlled software as pictures take physical form. This technology can add inanimate objects to your stage and create illusions around your guests.

Laser scanning is a highly accurate way to capture existing building or development site details. The use of laser light in advanced scanners generates 3D point clouds. A map of the exact shape and size of physical things can be created using point clouds.

AV companies rely on professional scanning companies to provide this service and then build the 3D model because the laser scanner used to produce the 3D map of your projection surface is widely used in construction

An event's laser scanning usually takes place a month before and can take anywhere from 4 to 2 days depending on the object's size and architectural complexity. Often, 3D scanning is done early in the morning when there is less activity, to get unobstructed views of a building.

In order to determine the audience perspective, your projection mapping expert will first convert the projection surface's digital architecture drawing into a design format. Given to content creators.

2D and 3D models, as well as graphic content, are commonly used in projection mapping information. Build your content library so you can mix and match it to create new effects. To take tourists on a historical journey, museums, for example, use projection systems.

The artist must now choose the viewpoint from which their work will be seen. Remember that projection mapping usually only works from one perspective. Virtual projectors then calculate the ideal position, rotation, size, lens ratio, projection distance, and lens size.

Our content is displayed on the panels via software. For this to work, you must use a jpeg sequence. Adobe Premiere's export options can help with this. Then we can record it in Cinema 4D with virtual cameras.

Conciliating digitally indicated projector positioning with real-world constraints requires projection mapping expertise. Most venues do not allow for this, but it is ideal for a projector mapping project.

Projector warping and media server mapping controls will need to be used together to make adjustments. Smooth transitions between images from different projectors are achieved using blended projection.

We can work with any geometry in 3D projection mapping. A 3D map can give previously static objects like buildings or stages dimension, movement, and depth. Architectural features like multiple windows or pillars are given new life.

It's definitely here to stay, given the increased use of video projection and 3D technologies. However, it has much more to offer than just that. As a result of its many benefits, it is increasingly used in other fields.

A larger LED panel, brighter lights, and the use of lasers are all being considered by the creators of this innovative technology. Remember that as technology advances and innovates, experiences will become more personalized, with material available for individuals.

Content is currently being developed for the general public. Because of the rising trend of wearable and portable technology like Google Glass, these predictions will soon be available for people to experience.

Modern users (Millennials and Generation Z) are more vulnerable to negative experiences due to the increasing use of cellphones, social media, and internet access. Because of this, they prefer interactive and collaborative content.

Not only DOREMI, but many other events are embracing the modern technical technique of project mapping. To ensure that your concept and brief are consistently and inventively delivered, our diversely skilled staff members are here to provide the ideal projection mapping experience. A tool like projection mapping can help us create memorable events, we believe.
