Leg pad 1-7 is fixed on first connecting rod 1-84, and pedal pad 1-15 is fixed on radar mounting base 1-82, and such first
Link mechanism and second connecting rod mechanism can pad 1-7 by leg and drive movement, the number of power source can so be effectively reduced, so that control
It makes relatively simple.
Automatic butt method, based on the above-mentioned bed chair Split type nursing bed with docking mechanism, the method includes such as
Lower step S301-S303:
Step S301 obtains the image of image acquisition units 1-9 acquisition；
Whether step S302 judges in described image comprising positioning auxiliary image 2-4；
Step S303, when including positioning auxiliary image 2-4 in described image, even if utilizing the positioning auxiliary image 2-4
The pose in the wheelchair portion 1；
Step S304 calculates control strategy according to the pose in the wheelchair portion 1, and the power wheel 1-2 is driven to rotate.
After the pose for completing wheelchair portion 1 for the first time calculates, real-time locating and tracking can be realized by Kalman filtering algorithm,
So that controller 103 can be moved and be compensated to its position deviation in continuous control wheelchair portion 1 under the auxiliary of vision, until
The pose in wheelchair portion 1 meets docking condition, i.e., it is directed at the slot 2-1.It is fixed in real time to be carried out using Kalman filtering algorithm
Position tracking can save subsequent calculation amount.
As shown in Fig. 9, the background color of the positioning auxiliary image 2-4 is white, is painted with dark border, dark border thereon
Wire frame there is one fixed width, there are four the auxiliary positioning dots of black (to be also possible to other numbers for tool in the dark border
Amount), four setting circle point symmetries are arranged in dark border, and dark border is that the pass of edge extracting is carried out in image processing process
Key element, the gradient value at edge is maximum and the border width of the collected dark border of image acquisition units 1-9 corresponding to
Number of pixels substantially determines, is conducive to the extraction that controller 1-3 carries out target area (region i.e. in dark border), is controlling
After device 1-3 extracts the corresponding image in target area, precise positioning is carried out using the setting circle point in target area and determines wheel
The pose in chair portion 1.
Specifically, even if including using the pose in the wheelchair portion 1 positioning auxiliary image 2-4 described in step S303
Following steps step S401-S403:
Step S401 obtains the marginal information in described image using Boundary extracting algorithm；
Step S402 obtains obtaining image using the edge that Morphological scale-space obtains target area；
Step S403 calculates the acquisition image using gray scale centroid method, obtains the pose in the wheelchair portion 1.
In above-mentioned steps S401, the gradient based on pixel in image carries out edge detection to target area, to get
Marginal information in whole image uses object-oriented edge acquisition methods in the present invention, based in positioning auxiliary image 2-4
The feature of edge gradient maximum gets marginal information, wherein the marginal information got includes the interior outside of dark border
Edge, detailed process comprise the following steps S501-S503:
Step S501 carries out convolution algorithm using gradient operator and described image；
Step S502 calculates gradient image grey level histogram, obtains in gradient image n-th maximum value as threshold value T,
Middle N is setting value；
Step S503 carries out binary conversion treatment to gradient image as threshold value using T and obtains the marginal information in image.
In step S402, Morphological scale-space is namely based on a series of images processing operation of shape, most basic morphology
Processing has corrosion and expansion, and both this uses extensively, is mainly used for eliminating noise, the independent pictorial element of segmentation and connection phase
Adjacent element, in the present invention, based on the relatively determining feature of the corresponding number of pixels of width on every one side of dark border to step
The image that rapid S401 is obtained first carries out dilation operation and carries out erosion operation again, has effectively removed the information of background, has obtained target
The frame in region, and the intramarginal part of target area is partitioned into as acquisition figure from image based on the edge of target area
Picture.Wherein, the width of the frame of target area is 1-2 pixel, and corresponding lines correspond roughly to original position assistant images 2-4
Dark border inward flange.
In step S403, gray scale centroid method is used to calculate the center position for obtaining each dot in image, and according to four
The center position of a dot calculates the center of entire positioning auxiliary image 2-4, can calculate the offset distance in wheelchair portion 1 accordingly
From can calculate the deflection angle in wheelchair portion 1 according to the distribution situation of the central point of four dots, wheelchair portion 1 can be calculated accordingly
Pose.
Of the invention bed chair Split type nursing bed and automatic butt method with docking mechanism passes through in the middle part of bed body portion
Slot for accommodating wheelchair is set, and being arranged includes docking directive wheel to make docking operation with the docking facilities for docking guided way
Simply, and this reasonable in design, patient separates and patient when docking without being substantially moved in wheelchair portion on nursing bed
Do not fall risk, automatic butt method can realize automatically docking for wheelchair portion and bed body portion using vision algorithm, without medical care
Personnel's operation, can save medical care resource, improve the autonomous actions ability of patient.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
