For judges, investigating the crime scene will help understand the crime and assist in the investigation of the case. If you do not personally investigate, you may cause misjudgments in some cases.
For example, in the murder of composer Phil Spector in 2007, the defense lawyer stated that the crime scene had a huge fountain at that time. The sound of the fountain disturbed the eyewitness by mistake and Spector acknowledged the case.
At that time, if the Faculty were to investigate the crime scene, they would be able to judge the authenticity of witness statements and better understand the development of the entire incident. But there are times when judges are not in the same city or state where the crime was committed and they will face difficulties when they go to crime scenes. There are also times when crime scenes are changed or rearranged for various reasons. The longer the crime is, the greater the chance of being changed. In addition, judges usually only get pictures or videos of crime scenes. However, because of restrictions on the photographer's perspective, light, etc., the crime scene in the judge's eyes is usually different from the real crime scene.
All of this will affect the fairness of the final verdict.
However, new technology has emerged. Using 3D imaging, panoramic video, robotics and VR technology, it can capture more complete images and allow judges to enter more immersive images.
For example, the research team at the Staffordshire University in the United Kingdom used green screens, video game software, and the latest VR helmets (such as the Oculus Rift and HTC Vive) to recapture crime scene VR images. The judge can also walk in the 3D world and check the details of the scene. Unlike pre-recorded clip videos, this real-time VR imaging is more like a primitive, simple documentary that gives lawyers a more objective view of the crime scene.
However, although this method is easy to use, the required VR helmets are expensive and the required computer accuracy requirements are quite high. Take the first-generation VR system, the HTC Vive is priced at $799, the Oculus Rift is priced at $600, and they also need additional computers and consoles to run. Therefore, their use still faces many difficulties.
To overcome these difficulties, our team developed a robot system called MABMAT. It was inspired by NASA's Curiosity Mars project to record an immersive video of the crime scene.
MABMAT can shoot 360-degree videos and pictures and connect to any smartphone or computer through the App. It only requires a basic helmet (such as a $15 Google cardboard helmet), but it can also achieve the effect of expensive helmets.
It does not require over-rendered 3D images and does not require a powerful computer, but it can capture the most accurate picture from any angle. Users can turn their heads and look up or down to zoom in or out. In this way, the judge will be able to take photos or videos on his own, as if he were on the scene at the crime scene.
Users can collect information in three ways:
First, a pre-configured road will be displayed in the helmet to record high-resolution 360-degree video;
Then it can be remotely controlled by a smartphone or tablet via Bluetooth;
In addition, it can use ultrasonic, mobile and infrared sensors for navigation, camera or video recording capabilities.
Now, the whole set of equipment costs only 395 US dollars, and because the open source robotic equipment is built on more and more inexpensive computer systems (such as Raspberry Pi and Arduino), the price may be lower in the future.
It seems that this kind of powerful, affordable black technology can make justice flourish. But what about its development? We will wait and see.
