New challenges for projection mapping
New challenges for projection mapping
Projection mapping allows images to be displayed on surfaces such as walls and buildings that’s widely used for entertainment, and Japan is now leading the world in finding new uses for this technology. On construction sites and in hospitals, projection mapping is making work safer and more accurate. We visit a major highway tunnel project in the Tohoku region, where images from data on rock strengths and weaknesses are projected onto the rock face to aid with explosive placement. And in the operating room, we see how images projected onto affected organs guide the surgeon’s hand.

00:12 Projection mapping is a technique for displaying images on walls, buildings or any kind of surface.
00:18 It's firmly established in the world of entertainment,
00:23 but now new applications are being found in other fields.
00:27 [Music]
00:30 This is Route 45, the major coastal highway through the Tohoku region.
00:35 [Music]
00:40 A large-scale tunnel is currently under construction.
00:44 [Music]
00:52 Explosives are used to carve the tunnel's path through the rock.
00:57 [Music]
00:59 Before each set of explosive charges is placed,
01:02 the rock face is sprayed with concrete to prevent collapses and to ensure worker safety.
01:08 When deciding where to set charges and how much explosive to use,
01:14 engineers need an accurate picture of the condition of the rock face.
01:18 They couldn't do this at the rock face since it was hidden under the concrete.
01:24 [Music]
01:31 Previously, we had to make calculations off-site
01:34 to estimate where the rock face was hard and where it was soft
01:38 in order to distribute the explosives suitably.
01:41 There were often conflicting opinions leading to less than ideal results.
01:45 Projection mapping turned out to be the solution to their problem.
01:51 [Music]
01:55 The rock face is measured before applying the concrete coating.
01:58 This data is used to create an image for projecting on the surface.
02:02 [Music]
02:06 Softer rock is shown in red and harder rock in blue.
02:12 [Music]
02:16 Visual aid makes it easy for engineers to place fewer charges in the softer areas,
02:21 increasing accuracy and effectiveness.
02:24 [Music]
02:30 Using projection mapping gives us far more precise control over blasting operations.
02:35 Now we don't have to worry about blasting away too much rock or too little.
02:40 It's really made our work much more efficient.
02:44 [Music]
02:46 The first of its kind in the world, this new technology makes the work of tunnelling much safer.
02:52 [Music]
02:56 Projection mapping is also revolutionising the medical world.
03:00 [Music]
03:03 Conventionally, surgeons refer to a monitor displaying the location of the part to be removed.
03:10 As they operate, they must keep switching their gaze between monitor and scalpel.
03:15 [Music]
03:20 In another world first, projection mapping has solved this problem too.
03:26 First, an infrared camera identifies the affected part.
03:30 [Music]
03:32 Using this data, an image is projected onto the part to show exactly where to cut.
03:40 The surgeon's eyes never leave the scalpel.
03:44 [Music]
03:50 In this model of a body part, the area illuminated in blue is to be removed.
03:56 Living organs are always moving, but the scanning camera precisely follows these movements.
04:02 [Music]
04:04 The time lag between movement and projected image is just 0.2 seconds,
04:09 meaning the surgeon sees things in close to real time.
04:13 [Music]
04:16 With projection mapping, we simply cut the areas illuminated by blue light and don't touch those that aren't.
04:23 This is making my field of liver surgery much safer.
04:29 Projection mapping has already had a huge impact on the world of entertainment.
04:34 In Japan, it's now been taken a step further and is transforming operating rooms and construction sites.
