Description
Technical Field
The invention relates to the field of mechanical cable jumping monitoring, in particular to a cushion supply system and method applying ankle detection.
Background
The machine rope jump, also known as a bungee, is a very exciting outdoor recreational activity that has emerged in recent years. The skipper stands more than about 40 meters (a high bridge, a tower top, a high building, a crane or even a hot air balloon, ties a long rubber strip fixed at one end at the ankle joint, then stretches the two arms, closes the two legs, and jumps with the head down.
The rubber band tied to the ankle of the jumper is long enough to allow the jumper to enjoy a few seconds of "free fall" in the air. When the human body falls to a certain distance from the ground, the rubber rope is pulled and tightened to prevent the human body from continuously falling, when the human body reaches the lowest point, the rubber is bounced again, the human body is pulled, and then the human body falls again, so that the bungee jumping process is repeated for many times until the elasticity of the rubber rope disappears.
Bungee has high requirements on physical quality, and people with heart and brain diseases cannot participate in the bungee. When the user is deeply myopic, the user should take care because the head of the user faces downwards when the hard bungee jumps down, and the user falls down at the acceleration of 9.8 m/s, so that the brain is easy to be congested and the retina falls off. Before jumping down, the patient should fully move all parts of the body to prevent sprain or strain. The dress should be as concise and fit as possible, and not wear clothes which are easy to fly or catch wind, otherwise, the exposure can be without the help of people. After jumping out, the user should take care to control the body and not to make the neck or arm be curled up by the elastic cord.

In addition, image filtering, namely, suppressing the noise of the target image under the condition of keeping the detail features of the image as much as possible, is an indispensable operation in image preprocessing, and the effectiveness and reliability of subsequent image processing and analysis are directly affected by the quality of the processing effect.
Due to the imperfections of the imaging system, the transmission medium, and the recording device, the digital images are often contaminated by various noises during the formation, transmission, and recording processes thereof. In addition, noise may also be introduced into the resulting image at some point in the image processing when the input image object is not as expected. These noises often appear as an isolated pixel or block of pixels on the image that causes a strong visual effect. In general, the noise signal is not correlated with the object to be studied-it appears in the form of useless information, disturbing the observable information of the image. For digital image signals, the noise table is more or less extreme values, and the extreme values act on the real gray values of image pixels through addition and subtraction to cause bright and dark point interference on the image, so that the image quality is greatly reduced, and the follow-up work of image restoration, segmentation, feature extraction, image identification and the like is influenced. Two basic issues must be considered to construct an effective noise suppression filter: the noise in the target and the background can be effectively removed; meanwhile, the shape, the size and the specific geometric and topological structure characteristics of the image target can be well protected.
One of the commonly used image filtering modes is a non-linear filter, generally speaking, when the signal spectrum and the noise spectrum are mixed or when the signal contains non-superimposed noise, such as noise caused by system nonlinearity or the presence of non-gaussian noise, etc.), the conventional linear filtering techniques, such as fourier transform, while filtering out noise, always blur the image details (such as edges, etc.) in some way, thereby causing the positioning accuracy of the image linear features and the extractability of the features to be reduced. The nonlinear filter is based on a nonlinear mapping relation of an input signal, a specific noise can be mapped to be zero approximately, the main characteristic of the signal is reserved, and therefore the nonlinear filter can overcome the defects of the linear filter to a certain extent.
Finally, it should be noted that each functional device in the embodiments of the present invention may be integrated into one processing device, or each device may exist alone physically, or two or more devices may be integrated into one device.
