Delivery and test





Real use case

1.  UAV Criminal Investigation Solution
The drone was used for armed field at first. As the science and technology develops and the society progresses, it is an inevitable trend to transfer the drone from government use to government and civil use. At present, China still faces the problems of insufficient government force, government equipment lack of technical content, weak coordination for multi-force and so on. However, the drone overcomes the above shortcomings by undertaking many tasks that seems impossible to be finished before.

In order to adapt to the new situation of criminal investigation and to enhance the multi-dispose of major criminal cases, drones have been equipped by some cities' criminal investigation departments for combating criminal offence. The drone can be used to satisfy new demands of daily criminal investigation work, such as investigation and evidence gathering, crime scene investigation, tracking and monitoring, arrest assistance and so on, realizing a new model of crime investigation reform and innovation.



UAV Criminal Investigation Use
1. crime scene investigation
In criminal case scene, site orientation map, overview map and detailed figure are usually filmed for recording and displaying the site orientation, surrounding environment, in and out path, evidence at the scene and so on. Using drone aerial photography can realize the comprehensive display of the panoramic crime scene from multi angle, multi-level and wide range. Adjusting the flight height and lens focal length can make general view and detailed pictures of the focus area and material evidence. At the same time, a preliminary search on the scene can be finished with filed being recorded. In the field, the scene pictures from the drone can be used to display the body status, surrounding environment and to acquire the scene information easily. What is more, the place of multiple cases can be directly displayed in a big range concerned with multi scenes, offering basis for the suspect activity track and path before and after the crime.

The drone added with infrared camera can be used to investigate and search the crime scene during the night with bad lighting conditions. Combined with 3D modeling technology, it can realize three dimensional reconstruction and measurement on the scene with high precision, offering more stereo and perceptual intuition scene information for the case analysis and punishment.




2. investigation and evidence-taken
when it is adverse for human power to make field investigation due to the big investigation area, complex terrain and the limitation of social factors, the drone can undertake the task of investigation and evidence gathering instead of manpower.

The drone can be used for investigation and evidence gathering when mounted with camera, low-light night vision device, infrared scanner and radar device. During criminal investigation process, the crowed residential area or inside the high-rise building within the community will restrict the further development of criminal investigation work to some extent. Under such circumstance, the suspects are very alert to the detectives, which increases the detection difficulty. On the contrary, the government can use drones to conduct aerial reconnaissance in high-rise buildings or dense residential areas, and analyze the suspects living environment, even the indoor circumstance by analyzing the real-time video and images information transmitted by the drones, which reduces the exposure rate effectively.



3. tracking and monitoring
Suspects gang crime often appears in some heavy and big series cases which usually require the investigators to learn about the organization structure, criminal law and foothold of the gang members. In fact, property loss cases often take place in urban dense area with big people flow and more complex situation, demanding for more government force. Worse, the suspects are easy to disappear into the crowd once something goes wrong. Under such circumstance, the drone can make aerial tracking on the suspects with face recognition and feature locking according to the position information and the video images, so as to identify the suspect targets. In some complex environment, the drone can carry out monitoring and capture scheme by combining the geographical information with the video information and position data.

4. arrest assistance
The drone plays an increasingly important role in arresting the suspects. The criminal suspects choose to run away at night in complex areas with rare people, which increases the arresting difficulty greatly. Multimedia acquisition system and HD camera are optional according to the tasks features. Under such circumstance, the drone with infrared camera can fast arrive at the incident scene for high quality thermal image and real-time audio gathering of the scene, which offers basis for commanders decision making All in all, the drone plays a crucial role in criminal investigation by greatly enhancing the scene treatment ability and improving the information acquisition security and stability.

The three dimensional prevention and combating system are big trends for future investigative work. The drone plays an irreplaceable role in criminal investigation, such as the timely detection of the case, precise guidance for the government and related affair, real time monitoring on the scene and posture, the unique view on the evidence and scene reconstruction, the catch of case tracks and routes, the suspects locking and arrest and so on.
