In the past two years, we have successfully developed a method that uses lasers to detect movement behind shielding barriers. Using this method, they are able to detect not only the location of objects behind barriers but also the movements of these objects.<\/p>\n
It is still in the research stage, but in the near future, it is hoped that these laser-based cameras will be installed in unmanned vehicles and rescue areas for people trapped in the rubble.<\/p>\n
This time, the Stanford Computational Imaging Lab has developed a method that can capture images inside a sealed room by injecting a laser through a small hole. This technology is called non-line-of-sight imaging. It is called the keyhole imaging system (Keyhole imaging) for short.<\/p>\n
This technology is a system that can shoot a laser beam through a keyhole-sized hole and take pictures of objects in the room. It’s a computer that uses a computer to project a laser beam from a small hole onto the objects in the entire room.<\/p>\n
This blind imaging technology is not entirely new. However, previously developed blind imaging cameras can only detect the back of places, such as corners of the wall. I was able to make out images behind a few barriers, but not to the point where I could make out the objects in the entire room.<\/p>\n
In the previously developed methods, the imaging method is to use reflective surfaces such as brick walls and smooth floors. This wall or floor needs to be in the field of view of both the camera and the subject.<\/p>\n","protected":false},"excerpt":{"rendered":"
