Projection mapping, also known as video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection.
These objects may be complex industrial landscapes, such as buildings. By using specialized software, a two or three dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on.
The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.
VIDEO MAPPING STAGES
Video mapping requires a meticulous study divided into two sections:
MANUFACTURING: Scenario, 3D modeling, Motion Graphics, Video Editing, GreenBox Projects etc.
PRODUCTION: Such elements as device, cabling, software and installation.
CORRECT AREA = IMPRESSIVE RESULT
Video Mapping is not based on sending images to a huge surface or building; however, impressiveness of video mapping works depends on the productions made. Since the building surfaces are subject to a particular architecture, it is necessary that elements such as windows, embossing or colons should provide integrity in such projects. It is required to distinguish the light show from video mapping. Instead of luminous effects with huge projections used, it is essential to move the building (i.e. collapsing of the building) by using video mapping software on the building and to impress people using the entire architecture thereof. Otherwise, a demonstration can be performed by reflecting a color spotlight or a film projection on the building as well.
Architectural specifications and environmental factors are key to detect the correct surface.
CRITICAL FACTOR : CALCULATION
Once the surface of appliance is detected, the devices need to send the visual from the correct distance. Whilst doing so, environmental factors may be a block. Being able to position the devices to the correct place is important in terms of budget and workability. Therefore, environmental factors need to be considered whilst choosing the subject building.
For example, we can enlighten a building with the dimensions 20 meters to 15 meters with two projection devices from a distance of 25 meters. But in case we cannot keep the distance of 25 meters due to environmental factors, we will need 4 projection devices to be able to enlighten the whole building, which will cause an increase of budget.
CORRECT DEVICE WILL MAKE EVERYBODY HAPPY
There are two types of devices:
* Full HD 1920*1080 or more Resolution Devices
* XGA 1024*768 Resolution Devices
For outdoor video mapping, we suggest to use at least 15.000 Ansi Lumen projection devices. But for some locations, in order to ensure quality and to not reduce the light power, there may be a need to use 20.000 Ansi Lumen or 30.000 Ansi Lumen projection devices. The purchasing of the device should be discussed by both parties in order to make the correct choice.
