Canadian photographer Eric Paré has constructed a bullet-time rig utilizing 15 Raspberry Pi cameras synchronised to document photos at precisely the identical second from completely different angles. The cameras then create a sequence of photographs that present the topic, often somebody leaping within the air it appears, from a number of viewpoints. These photographs can then be put collectively as a video to indicate the individual frozen in mid-air because the digital camera seems to pan round them. The method, made standard by the combat scenes within the film The Matrix, requires that the cameras used are all pointing at precisely the identical spot and that the shutters are tripped both on the similar second or in sequence.
Eric often makes use of a group of EOS DSLRs for his bullet-time movies however thought it could be attention-grabbing to make use of the tiny Raspberry Pi cameras because the lenses will be positioned a lot nearer collectively to create smoother movement within the last video. To do that he mounted 15 cameras on an aluminium rail and synchronised them utilizing a single dashboard that might additionally management the settings of every digital camera.
Issues arose as a result of broad angle lens of the Raspberry Pi digital camera and since the cameras are mounted on their PCB utilizing a gum glue that doesn’t maintain them in a selected place. This meant that whereas the boards had been all dealing with the fitting approach the cameras weren’t, and the footage produced was jerky. Eric solved this challenge by remounting all of the digital camera items on to the boards utilizing a skinny adhesive.
Every digital camera within the rig was linked to the laptop computer by way of an Ethernet cable to a change and Eric triggered the set-up utilizing a Bluetooth presenter controller. He says he didn’t have to make any customized electronics for the rig when capturing with steady lighting, however he did make a brand new management board to slot in the rig when he needed to make use of flash.
For this experiment Eric used the Pi 3B+ with model 2 of the Raspberry Pi digital camera module. He says the identical set-up would additionally work with the newer Excessive High quality Pi digital camera with its 12MP sensor and interchangeable C-Mount lens system.
