Stair-climbing and window-turning theft behavior detection method and system based on optical flow method target tracking

Abstract: The invention discloses a stair-climbing and window-turning theft behavior detection method and system based on optical flow method target tracking. The method and system are mainly used for automatically detecting a moving target of a stair-climbing and window-turning in video monitoring. The method comprises the following steps: detecting and tracking a moving target in a monitoring video by adopting an optical flow method; calculating a behavior track of the moving target; And matching the behavior track of the moving object with a stair climbing theft behavior rule. The system comprises amoving target detection tracking module, a behavior track calculation module and a rule matching module. According to the technical scheme of the embodiment of the invention, the optical flow method is used for detecting the theft behavior of climbing stairs and turning windows at night. According to the invention, a moving target with stair climbing and window overturning behaviors in a video canbe rapidly detected, and an alarm can be given out in time, so that the method has a great practical value for early discovery of potential safety hazards, and provides scientific basis for protecting property and personal safety of residents, maintaining social security and attacking and preventing crimes.

Ring-type stair climbing assistance machine facilitating climbing stairs

Abstract: PROBLEM TO BE SOLVED: To facilitate climbing stairs safely and prevent an installed device from getting in the way of a walker. SOLUTION: By attaching a driving machine with a ring hanging down to a rail fixed on a ceiling, the device does not get in the way of a walker going up and down since the device is installed on the ceiling, and it is safe and easy for the walker to go up since the device is a ring type and is pulled before the device is pulled up.

Transformable intelligent stair climbing wheelchair

Abstract: The invention provides a transformable intelligent stair climbing wheelchair. The transformable intelligent stair climbing wheelchair mainly comprises a frame, a frame transformation mechanism, a manned upper platform, a front wheel assembly and a rear wheel assembly. The frame transformation mechanism is arranged in the center of the frame, the manned upper platform is arranged above the middle of the frame, the front wheel assembly is arranged at the bottom of the front end of the frame, and the rear wheel assembly is arranged at the bottom of the rear end of the frame. The transformable intelligent stair climbing wheelchair has the advantages that the mass is low, the structure is simple, space is reasonably utilized, the gravity center of the wheelchair is balanced, and stair going-up and going-down are quick. Stable and comfortable flat ground walking and stair climbing functions can be achieved, the safety mechanism effect exists in the stair climbing process, and personal safety is guaranteed to a larger degree. People with disabled lower limbs can live at home or independently travel in communities and climb stairs through the transformable intelligent stair climbing wheelchair, recovery of the physical function and confidence of people is promoted, people enjoy driving happiness just like normal people, and high social value is achieved.

Transportation robot with step climbing mechanism

Abstract: The utility model provides a transportation robot with a step climbing mechanism. The electric vehicle comprises a controller, a vehicle frame and wheels arranged at the bottom of the vehicle frame. the wheels are connected with a first motor; step climbing mechanisms are arranged on the left side and the right side of the frame correspondingly. The step climbing mechanism comprises an arch-shapedtelescopic leg, a linear guide rail and an air cylinder. the linear guide rail and a cylinder body of the air cylinder are respectively fixed on the frame; the arch-shaped telescopic leg is connectedwith the linear guide rail in a sliding manner; wherein a piston rod of the air cylinder is connected with the arch-shaped telescopic leg, the arch-shaped telescopic leg comprises a middle concave part, a front leg and a rear leg, the tail end of the front leg is connected with a front climbing step wheel, the tail end of the rear leg is connected with a rear climbing step wheel, the front climbing step wheel is higher than the rear climbing step wheel, and the controller is electrically connected with the first motor and the air cylinder. The automatic stair climbing device has the advantages of achieving automatic stair climbing, and being simple in structure and low in cost.
