Computer vision is transforming how we prepare for and respond to natural disasters. Below are notable real-world applications of computer vision in this area.

• Disaster prediction: By analyzing satellite images, drone footage, and ground-level visuals, computer vision systems can detect early warning signs - like shifts in cloud patterns, rising water levels, or lava flows - enabling accurate weather forecasting and timely alerts.
• Optimizing relief resources: In disaster-prone areas, computer vision helps track the path of hurricanes, wildfires, and floods, supporting evacuation planning and the strategic allocation of relief resources before the crisis hits. Once a disaster occurs, computer vision tools can assess the extent of the damage by comparing pre- and post-event imagery, estimating repair costs and guiding recovery efforts.
• Search and rescue: Computer vision for drones has transformed how rescue teams locate survivors. Thermal imaging, powered by computer vision, can detect heat signatures in low-visibility conditions like smoke or darkness, helping identify survivors in hard-to-reach zones. Additionally, object detection algorithms enable rescue robots and drones to pinpoint missing persons by analyzing visual data for human shapes or specific features like clothing. With the integration of geospatial data and advanced image analysis, search and rescue teams can rapidly assess areas, ensuring swift and accurate operations to save lives.

11. Robotics

Computer vision is the eyes of modern robotics, empowering machines to perceive, understand, and interact with their surroundings.

• Object detection and recognition: Robots use 2D and 3D imaging powered by computer vision to identify and locate objects for tasks like sorting, inventory management, and assembly. In industrial settings, vision-guided robots perform high-precision tasks, from installing car components to conducting quality inspections, with greater speed and accuracy.
• Autonomous navigation and mapping: By combining data from cameras, LiDAR, and other sensors, robots build real-time 3D maps of their environment. This allows delivery bots, autonomous vehicles, and drones to detect obstacles, track movement, and navigate safely even in complex, dynamic environments.
• Gesture and pose recognition: Computer vision enables robots to respond to human body language or hand signals. For example, facial and emotion recognition helps service robots - such as those assisting the elderly - understand emotional cues and offer appropriate responses. Robots can even identify which object a person is holding and provide support or relevant information.

12. Sports analytics

Computer vision is changing the game - literally - by offering smarter ways to analyze athletic performance, team strategies, and game dynamics.

• Automated video analysis: Footage from computer vision systems can be valuable when it comes to game analytics. Coaches and athletes can review movement patterns, assess techniques, and identify areas for improvement. This doesn’t just apply to one’s own team - it also helps analyze opponents to gain a competitive edge.
• Player tracking: Using key-point annotations and bounding boxes, computer vision systems follow individual players or entire teams across the field. These systems recognize actions like running, passing, or defending and can even suggest optimal player positioning. This makes it easier to visualize performance gaps and fine-tune strategies during training or live games.
• Ball tracking: In ball-based sports like tennis, cricket, or soccer, ball tracking is crucial. Computer vision models detect and trace the ball’s motion in 3D, predict its trajectory, and determine key moments - like whether it hit the wicket or crossed a line. Even in fast-paced games where the ball disappears behind players, advanced models handle the complexity with surprising accuracy.
