Description
Technical field
The present invention relates to human body recognition technology, accurately know method for distinguishing particularly to human body in a kind of air conditioning applications.
Background technology
The issue of Changhong CHiQ air-conditioning, has overturned tradition, and it is based on unique body state cognition technology, changed to software definition air-conditioning by hardware definition air-conditioning on the one hand, realize working in coordination with between people and the interaction of air-conditioning, equipment, while ensureing human comfort, energy-saving and cost-reducing；On the other hand from user's request angle, meet user's request by plurality of application scenes pattern rather than pure function.Therefore, the traditional air conditioner theory of " hardware+function " overturned by Changhong CHiQ air-conditioning, has started the development new direction of " software+application scenarios pattern ".
Changhong CHiQ air-conditioning is according to the man-machine distance of perception identification, crowd's quantity, position etc., for zones of different, automatically adjusts the parameters such as air-out mode, wind speed, wind direction, dynamically adjusts the comfort level of each subregion.More marvellous is, people can set VIP people's mode of priority for ad-hoc location within the scope of air-conditioning wind-force angle of radiation, when user is when preferential comfort zone, CHiQ can carry out temperature, humidity, wind speed and direction adjustment targetedly, and old friend's body state Intelligent Identify is the function of Changhong CHiQ air-conditioning core the most.
For reducing cost, Changhong CHiQ air-conditioning adopts the low resolution non-brake method mid-infrared sensor of 4*16 to replace the infrared camera of high score ratio high cost, and realizes human body information identification under certain algorithm.Usually, human body presents three kinds of postures before air-conditioning, namely stance, sitting posture, sleeping position, although CHiQ air-conditioning room temperature refrigeration and high wind refrigeration under be easy to be identified to stance, sitting posture and sleeping position, but when high wind freezes, sleeping position is just very easy to the situation that leakage identifies occur.
Summary of the invention
The invention aims to solve in prior art, when air-conditioning high wind freezes, the problem that number leakage is known easily occurs when human body is in sleeping position.
For reaching above-mentioned purpose, the present invention provides the method for the lower Intelligent Recognition human body sleeping position of a kind of high wind refrigeration, it is characterised in that comprise the steps:
Step one, when air-conditioning high wind refrigerating operaton, infrared sensor rotate carry out progressively scanner uni data acquisition；
Step 2, the data collected are arranged in temperature pattern by according to certain rule, and obtain the variance of temperature pattern；
The data of interpolation processing are analyzed for step 3, utilization medium filtering and medium filtering processes；
Data after Filtering Processing are carried out contrast process by step 4, variance in conjunction with described temperature pattern, obtain human body temperature under sleeping position and quantity information；
Step 5, relation by temperature and distance obtain the distance between people and air-conditioning.
Specifically, in step one, the low resolution non-brake method mid-infrared sensor adopting resolution to be 4*16 carries out progressively scanner uni data acquisition.
Specifically, described infrared sensor carries out progressively scanning and data acquisition by 1 ° of-1 ° of-1 ° of-13 ° of rotation.
Specifically, to carry out the concrete grammar of medium filtering process as follows for step 3:
Pixel in plate being ranked up according to the size of pixel value, what generate monotone increasing is one-dimensional data sequence, then exports one-dimensional medium filtering:
G (x)=med{f (x-k), (k ∈ W) }
Wherein, f (x), g (x) respectively original image and image after processing, W is one-dimensional template, its in length and breadth the value respectively excursion on direction be 1*7 and 1*21 region.
The invention has the beneficial effects as follows: original image is carried out variance and middle finger Filtering Processing, utilize the difference extraction human body information of the image after asking variance and medium filtering and original image, even if under high wind freezes, ensure that human body stance and sitting posture information obtain the information of human body sleeping position when can recognize that, eliminate situation about Lou identifying, improve the human body information discrimination of air-conditioning.
Detailed description of the invention
Hereinafter technical scheme is described in further detail.
The present invention is directed in prior art, when air-conditioning high wind freezes, the problem that number leakage is known easily occurs when human body is in sleeping position, it is provided that the method for the lower Intelligent Recognition human body sleeping position of a kind of high wind refrigeration, comprise the steps:
Step one, when air-conditioning high wind refrigerating operaton, infrared sensor rotate carry out progressively scanner uni data acquisition；
Step 2, the data collected are arranged in temperature pattern by according to certain rule, and obtain the variance of former temperature pattern；
The data of interpolation processing are analyzed for step 3, utilization medium filtering and medium filtering processes；
Data after Filtering Processing are carried out contrast process by step 4, variance in conjunction with described image, obtain human body temperature under sleeping position and quantity information；
Step 5, relation by temperature and distance obtain the distance between people and air-conditioning.
Medium filtering is based on a kind of nonlinear signal processing technology that can effectively suppress noise that sequencing statistical is theoretical, the ultimate principle of medium filtering is that the Mesophyticum of each point value in a neighborhood of this point of the value of any in digital picture or Serial No. is replaced, allow the actual value that the pixel value of surrounding is close, thus eliminating isolated noise spot.Because the data in the present invention are relatively fewer in the vertical, it is contemplated that the DeGrain of process, therefore only it is filtered data transversely processing.For accelerating arithmetic speed, present invention employs a kind of one-dimensional sleiding form being continually changing, pixel in plate be ranked up according to the size of pixel value, what generate monotone increasing is one-dimensional data sequence, then exports one-dimensional medium filtering:
G (x)=med{f (x-k), (k ∈ W) }
Wherein, f (x), g (x) respectively original image and image after processing, W is one-dimensional template, its in length and breadth the value respectively excursion on direction be 1*7 and 1*21 region.
In order to eliminate the situation that Conventional median filtering method occurs that in high wind refrigeration situation leakage identifies, before underway value filtering, present invention employs the way that original image is asked variance, contrast original image and variance image thereof, being not difficult to find out there is the place of people in original image, variance yields shows relatively large, utilize this characteristic, then carry out contrast with the image of medium filtering and effectively can must fall the information of human body.
Embodiment
Under high wind freezes, respectively to when there being a people to fall asleep in the radiation scope of air-conditioning, a people falls asleep when stand with a people, when a people is sleeping, a people is seated and a people stands, after gathering data and processing, it is possible to the accurately errorless characteristic information providing human body.Through Multiple-Scan, identify checking, identify (identifying less than people) and misrecognized (being people by object or other thermal source identification) without leakage.
