Stereo Analysis

What is Stereo Analysis?

2D technology has been playing an important role in the image processing market. However, the trend towards 3D solutions has become increasingly significant due to the growth of AI applications in recent years. 3D information is used in particular when volumes, shapes or 3D positions of objects are analyzed. It can also be used to handle tasks in examining defects in objects and images that do not have enough contrast for 2D but shows recognizable difference in spatial data.


Advantages of this solution compared to 2D cameras:

Filters shadow and background interference
Object segmentation
Distance, height, depth, judgment, and target positioning

3D motion tracking and estimation


The Dahua Stereo Analysis adopts two lenses to capture two images of the same scene and computes "optical parallax" of spatial points in two images, providing 3D information of the scene it observes. Combining deep learning algorithm, it can recognize people’s behavior that can help secure unguarded scenarios 24/7.




Benefits

  • Strand Detection

    Detect a target person who stays in the area for too long
  • People Approach

    Detect the distance between a person and approaching people or pedestrians.
  • Fall Detection

    Detect and alert when a person suddenly falls to the ground in the monitored scene.
  • People No. Error Detection

    Detect abnormal number of people in the area and send an alarm.
  • Violent Detection

    Detect violent movement or fight in the area and send an alarm.
  • 3D-Perception

    Combining binocular vision measuring system with deep learning algorithm, it can provide 3d-perception.

Solutions and Products

Highlights

·Low requirements for network bandwidth, significantly reducing transmission pressure

·High cost performance value

Product selection

Typical Scenarios

  • ATM

    People Approach helps prevent suspicious individuals from approaching/following other people in the ATM machine area. Violence Detection detects fighting inside the monitored area, and sends real-time alarm.

  • Prison

    Fights easily break out among prisoners. Violence Detection detects this kind of behavior and sends real-time push notifications to alert the guards regarding the situation.

  • Nursing home

    In case of an accident like falling down, the Fall Detection can detect it immediately and alert the nurses to act accordingly, ensuring the safety of the elderly residents.
