Detailed Description
The present invention will be further described in detail with reference to the following specific embodiments in conjunction with the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
Referring to fig. 1 to 3, the wrist type smart terminal includes a band part 100, an input device 200, an output device 210, a storage device 230 of the wrist type smart terminal, a computing device 220, and a power supply battery 240, which are disposed inside a housing of the wrist type smart terminal, as a whole, and are not visible from the outside.
Wherein the input device 200 comprises a plurality of infrared camera means, which are divided into two groups a and B. The first group a is disposed on a side surface of the main housing of the wrist type intelligent terminal, for example, fig. 2 shows that two infrared camera devices are disposed on each side surface of the main housing as input devices. The design is adopted because in the practical application process, the wearing habit of the watch is different for each person, for example, the person likes to wear the left hand and the person is used to wear the right hand, so that in order to increase universality, input devices are arranged on two side surfaces of the main shell. The above description is not limited to two input devices per side, and in practical application, a larger number of input devices may be added according to the requirement of the actual gesture recognition, and of course, the increase of the input devices entails the increase of manufacturing cost. In addition, according to wearing habits of the wrist type device, one prefers to wear the output device, that is, the display screen, on the wrist on the back side of the hand, and one prefers to wear the display screen on the wrist on the side of the hand; some people like the wrist to be flat for gesture operation, such as finger impact, and some people like the wrist to be slightly tilted for gesture operation. In order to adapt to the condition that the infrared camera device serving as the input device can completely and clearly obtain the infrared image during gesture operation under various wearing modes and operating modes, a second group of input devices B are also arranged. The infrared camera device B is arranged on the side surface of the part of the belt component opposite to the main shell of the wrist type intelligent terminal. Correspondingly, the inside of the belt component or the inside of the wrist buckle adjacent to the area can comprise a flexible PCB board for completing power supply and information data communication of the infrared camera device B.
The infrared camera device A and the infrared camera device B are both used for collecting infrared image data of the wearing hand, and as the actual position of the infrared camera device B is arranged in the middle of the belt part, a flexible PCB (printed Circuit Board) is required to be arranged in the belt part or in the nearby wrist buckle for sending the collected image data to the computing equipment for processing, and likewise, an operation command, a control command and the like are also transmitted through the flexible PCB. The infrared camera device A and the infrared camera device B are used as input equipment, the positions of the input equipment are different, the input equipment is not divided into primary and secondary parts, the infrared camera device A and the infrared camera device B can be used for completing infrared image acquisition, the structures of the input equipment and the infrared camera device B can be identical or different, and preferably, the belt part comprises a clamping part, and the infrared camera device B is integrated with the clamping part of the belt part, so that the whole device is simpler and more attractive in appearance.
The wrist type intelligent terminal specifically works as follows:
1. the wrist type intelligent terminal is awakened in various modes, such as a button type mode, an acceleration induction type mode and the like. After waking up the wrist intelligent terminal, the input device starts infrared shooting, and the output device is lightened.
At this time, the wrist intelligent terminal is worn on the hand, and in the initializing process, the initial judgment is firstly carried out according to the image obtained by the input device, so as to judge whether the wrist intelligent terminal is worn on the left hand or the right hand, and whether the output device faces the back hand direction or the palm hand direction. After the direction is determined, the infrared camera device capable of obtaining clear gesture images is adaptively enabled to be in a working state. For example, when the wrist type intelligent terminal is worn on the left hand and the output device faces the palm direction, the input device on the right side face of the main shell of the wrist type intelligent terminal enters a shooting state, and other input devices enter a dormant state. Such operations are used to save power and system computing/storage resources or to improve recognition accuracy.
2. The input device entering the shooting state collects infrared image data of the wearing hand and transmits the influence data to the computing device.
3. The computing equipment performs image processing on the acquired infrared image data, and computes gesture operation information in the acquired infrared image data.
4. The storage device stores a database of gesture operation information and a control command corresponding to the gesture operation information; the computing device compares the gesture operation information obtained through calculation with gesture operation information stored in the storage device, when the similarity reaches above a similarity level threshold, a control command corresponding to the gesture operation information is queried, and then the wrist type intelligent terminal or other terminal devices connected with the wrist type intelligent terminal are controlled according to the control command. And when the similarity does not reach the similarity level threshold, not performing operation, and continuing to perform image processing on the acquired infrared image data.
In the above process, the power supply device (such as a battery) supplies power to the input device, the output device, the computing device and the storage device.
In the implementation process, the computing device in step 3 performs image processing on the collected infrared image data, and calculates gesture operation information in the collected infrared image data, which is an important part of the whole implementation process, and determines whether the recognition accuracy of the finger can be refined. For convenience of description, the finger wearing the wrist type intelligent terminal is partitioned, 300-thumb fingertip joint is shown in fig. 4; 301,302, 303-first, second, third joints of index finger; 304,305, 306-first, second, third joints; 307,308, 309-ring finger first, second, third joints; 310,311, 312-first, second, third joints of the little finger, the simplest way of gesture operation from the physiological point of view of the human body is the spreading, collapsing or striking of the fingers. An example of a finger strike is a finger strike with the thumb being bent 90 degrees by accident with the other fingers, the third joint of the thumb tip and the other four fingers completing the finger strike operation. That is, any one of the thumb tip 300 and the third joint (303,306,309,312) of the other four fingers can perform the finger-clicking action, and of course, any one or more of the thumb tip joint 300 and the second joint (302,305,308,311) of the other four fingers can perform the finger-clicking action, and any one or more of the thumb tip joint 300 and the first joint (301,304,307,310) of the other four fingers can perform the finger-clicking action, which is not as convenient as the direct and third joints, but is not impossible to perform.
The infrared image data processing of the finger can be performed in the following two ways:
as shown in fig. 5, the image data of the tracked five-finger part is subjected to linear simulation, five fingers correspond to five folding lines, each linear part in each folding line corresponds to the joint of each finger in fig. 4, and corresponding gesture operation information is obtained through calculation of the relation between the five folding line data, for example, in fig. 6, a linear simulation diagram is shown when the joint of the thumb fingertip and the third joint of the index finger fingertip are contacted, and at this time, the joint of the thumb fingertip and the index finger fingertip are considered to complete one finger-tap gesture operation.
And secondly, carrying out contour simulation on the tracked image data of the five-finger part, wherein the five fingers correspond to five contour lines, and obtaining corresponding gesture operation information through calculating the relation between the five contour lines.
Further, the gesture motion itself may include a single motion, a double motion, a long press motion, and the like. For example, the computing device may detect two finger impacts in a short period of time through the input device and be identified as a double-click action.
For the control commands corresponding to each gesture action, the control commands can be set according to personal habits and favorites, for example, the finger-clicking actions of the thumb fingertip and the index finger fingertip are set to be 'certain', the finger-clicking actions of the thumb fingertip and the small finger fingertip are set to be 'returning' or 'withdrawing', the finger-clicking actions of the thumb fingertip and the middle finger fingertip are set to be 'last page' or 'last head', the finger-clicking actions of the thumb fingertip and the ring finger fingertip are set to be 'next page' or 'next head', the gathering operation of the five finger fingertips is set to be 'homepage', and the corresponding relation between other control commands and the finger-clicking actions can be added, modified and deleted according to personal wishes.
According to the method, the gesture actions are shot through the infrared camera device, the computing equipment performs linear simulation and contour simulation on the shot images, so that the reason why the gesture actions are caused can be rapidly and accurately judged, different control commands are corresponding to different gesture actions, namely, the wrist type intelligent device or other terminal equipment connected with the wrist type intelligent device is controlled by one hand through the gesture actions, the inconvenience that in the prior art, the hand wearing the wrist type intelligent terminal is only used as a carrier, the other hand is required to operate the intelligent terminal is overcome, the controllability and the operation convenience of the wrist type intelligent device and the corresponding terminal equipment are greatly improved, the computing equipment only processes the infrared images of fingers, the efficiency of identifying the gesture actions is improved, the linear simulation is further adopted, and the accuracy and the processing speed of identification are further improved.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
