[0050] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B", and may include only A, only B, or A and B. The singular terms "one" and "the" may also include plural forms.

[0052] At present, the temperature measurement baby monitoring products on the market use traditional temperature measurement sensors, and the temperature detection can only detect the temperature within a point range; at the same time, due to the installation location, the detected temperature value reflects the temperature around the baby, rather than the temperature of the measured target, and there is a temperature difference of 2 to 4 degrees, which sometimes leads to incorrect judgment of the baby's body temperature, false detection or missed detection. In addition, since the baby may turn over when sleeping, the baby will appear in the blind area of ​​the temperature measurement sensor, resulting in the temperature measurement sensor being unable to detect the baby's body temperature in time, and it is difficult to achieve detailed and accurate temperature detection during the baby care process.

[0053] To this end, the present invention provides a method for detecting abnormal conditions of infants, the method comprising: obtaining a temperature array collected by an infrared array sensor; constructing a temperature array binary map based on the temperature array; and determining whether the infant is in an abnormal condition based on the temperature array binary map. The present invention first collects the temperature array through an infrared array sensor, and then constructs a temperature array binary map based on the temperature array, and obtains information through the temperature array binary map whether the infant is currently in an abnormal condition. The temperature collection of the present invention covers the detection blind spots caused by the infant's turning over and other behaviors, has a wide monitoring range, and makes more accurate judgments. It can detect the infant's abnormal behavior in a timely manner, and achieve a more detailed and safe care function when the infant is sleeping at night or the caregiver is not around.

[0054] See attached Figure 1 , Figure 1 1 is a flow chart of main steps of a method for detecting abnormal conditions of infants according to an embodiment of the present invention.

[0055] like Figure 1 As shown, the method for detecting abnormal conditions of infants in the embodiment of the present invention mainly includes the following steps S100 to S300.

[0056] Step S100: Acquire a temperature array collected by an infrared array sensor.

[0057] In this embodiment, the temperature array is first collected by using an infrared array sensor. The infrared array sensor can be a thermopile infrared array sensor. The temperature distribution of the crib can be collected by the thermopile infrared array sensor. Each temperature corresponds to the temperature of the area projected by a pixel. The temperature collected by the crib is changed from the temperature value of the detection point to the temperature value of the detection area. The detection content is more substantial and the amount of data is larger.

[0058] Step S200: constructing a temperature array binary image based on the temperature array.

[0059] In this embodiment, a temperature array binary map is constructed based on the collected temperature array, and data matching the human body temperature and the ambient temperature in the temperature array are distinguished to construct the temperature array binary map.

[0060] Step S300: determining whether the baby has an abnormal condition based on the temperature array binary image.

[0061] In this embodiment, whether the baby is currently in an abnormal condition is analyzed based on the obtained temperature array binary image, and further processing is performed on the abnormal condition.

[0062] Based on the above steps S100 to S300, by collecting the temperature array and constructing a temperature array binary map according to the temperature array, and then judging whether the baby is in an abnormal condition based on the temperature array binary map, the baby's abnormal behavior can be detected in time, and a more detailed and safe care function can be achieved when the baby is sleeping at night or the caregiver is not around. In addition, the use of infrared array sensors for temperature collection can cover the detection blind spots caused by the baby's turning over and other behaviors, with a wide monitoring range and more accurate judgment.

[0063] The above steps S100 to S300 are further explained below.

[0064] In one embodiment, for step S100, a temperature array collected by an infrared array sensor is obtained. Specifically, the temperature distribution of the crib can be collected by the thermopile infrared array sensor, and each temperature corresponds to the temperature of the area projected by a pixel, thereby avoiding the problem that a traditional temperature measurement crib usually uses a single temperature measurement sensor to monitor the temperature of the crib, and when the baby appears in the blind area of ​​the temperature measurement sensor due to rolling over or other behaviors, the temperature measurement sensor cannot detect the baby's body temperature change in time.

[0065] For step S200, in one embodiment, constructing a temperature array binary image based on the temperature array includes: binarizing the temperature array based on a preset temperature threshold to obtain a first preset value and a second preset value; using the first preset value as a foreground pixel and the second preset value as a background pixel; and constructing a temperature array binary image based on the foreground pixels and the background pixels.

[0066] Specifically, the collected temperature array T is processed according to the preset temperature threshold. ij Binarization is performed. In this embodiment, the preset temperature threshold is set to 35°, and 35° is used to distinguish the temperature array T ij The human body temperature and the ambient temperature in the temperature array are greater than 35°T ij The value of is set to the first preset value, the first preset value is 1, and the T values ​​less than 35° in the temperature array are ij The value of is set to a second preset value, the second preset value is 0, and then the pixels of the first preset value are used as foreground pixels, and the pixels of the second preset value are used as background pixels. It can be understood that the pixel color of the first preset value is white, and the pixel color of the second preset value is black, and then a temperature array binary image is constructed based on the foreground pixels and the background pixels.

[0067] The above is the description of step S100 and step S200 , and the following will further describe step S300 .

[0068] With respect to step S300, in one embodiment, determining whether the infant has an abnormal condition based on the temperature array binary image includes: obtaining a connected area of ​​the infant's exposed body parts based on the temperature array binary image; calculating the area of ​​the connected area; and judging whether the infant has an abnormal condition based on the area of ​​the connected area.

[0069] Specifically, the obtained temperature array binary image is first marked by a one-step marking method to obtain the connected area of ​​the exposed body parts of the infant, and then the area of ​​the connected area of ​​the exposed body parts of the infant is calculated, and based on the area of ​​the connected area, it is determined whether the infant has an abnormal condition.

[0070] The one-step labeling method specifically includes the following steps:

[0071] (1) Starting from the first pixel in the temperature array binary image, set the label of the current pixel to 1 and execute step (2).

[0072] (2) If this pixel is a foreground pixel but has not been labeled, label it with the current label and add it as the first element in the queue, then perform step (3). If it is a background pixel or has been labeled, repeat step (2) for the next pixel in the image.

[0073] (3) Pop an element from the queue and check its neighborhood. If the neighborhood is a foreground pixel and has not been labeled, give it the current label and add it to the queue. Repeat step (3) until there are no more elements in the queue.

[0074] (4) Return to step (2) to obtain the next pixel in the image and increase the current label by 1. Calculate the area S of the connected region based on the labeled temperature array binary map:

[0075] S = ∫∫b(x,y)dxdy

[0076] Among them, b(x,y) represents the value of each coordinate pixel of the temperature array binary image, which is 1 or 0. 1 represents the exposed body part of the baby, and 0 represents the baby's no exposed body part. dx,dy represent the width and length of the pixel.

[0077] In one embodiment, the abnormal condition includes a kicking-off condition; the judging whether the infant has an abnormal condition based on the area of ​​the connected region includes: determining the exposed body parts of the infant; obtaining a corresponding first preset threshold based on the exposed body parts of the infant; judging whether the area of ​​the connected region is greater than the first preset threshold; and if so, determining that the infant has kicked-off the quilt.

[0078] In one embodiment, the method further includes: determining the exposed body part of the infant; judging whether the exposure time of the body part is greater than a second preset threshold; and if so, determining that the infant is kicking off the quilt.

[0079] Specifically, multiple first preset thresholds are preset according to different exposed body parts. For example, when the exposed parts are arms or legs except the baby's head, the first preset threshold is appropriately increased; when the exposed parts are the trunk, the first preset threshold is appropriately reduced. The trunk includes the abdomen, chest, and pelvis. When the arms or legs are exposed, the impact on the baby's sleep is small. The exposure of the abdomen, chest, pelvis and other trunk parts will cause diarrhea, waist pain and other conditions in the baby. Therefore, each body part corresponds to a second preset threshold. When it is determined that the exposed body part of the baby is the arms or legs, the corresponding second preset threshold should be appropriately increased; when it is determined that the exposed body part of the baby is the trunk, the corresponding second preset threshold should be appropriately reduced.

[0080] The connected area of ​​the baby's exposed body parts is obtained through the temperature array binary map, and then the area of ​​the baby's exposed body parts is calculated through the connected area. Finally, it is determined whether the baby is in a kicking-off state based on the area of ​​the exposed body parts. The baby's kicking-off behavior can be detected in time, and it is judged whether the exposed body parts will affect the baby's health, thereby achieving more meticulous care functions.

[0081] After the exposed body parts of the baby are determined, the exposure time of the exposed body parts of the baby is obtained to determine whether the exposure time exceeds a second preset threshold corresponding to the exposed body parts. If so, it is determined that the baby has kicked off the quilt.

[0082] The connected area of ​​the baby's exposed body parts is obtained through the temperature array binary map, and then the area of ​​the baby's exposed body parts is calculated through the connected area. The baby's exposed body parts are determined according to the area and circularity of the exposed body parts, and combined with the exposure time of the exposed body parts, it is judged whether the baby is in a kicking quilt state. The kicking quilt detection accuracy is improved, the baby's kicking quilt behavior can be detected in time, and it can be judged whether the exposed body parts will affect the baby's health, realizing more meticulous care functions.

[0083] In one embodiment, the abnormal condition includes a condition where the head is covered; the judging whether the infant is in an abnormal condition based on the area of ​​the connected region includes: determining the exposed body parts of the infant; when the body parts do not include the head, obtaining the length of time the head is not exposed; judging whether the length of time the head is not exposed exceeds a third preset threshold; if so, determining that the infant's head is covered.

[0084] Specifically, first determine the exposed body parts of the baby. If the exposed body parts of the baby do not include the head, obtain the length of time the baby's head is not exposed. When the length of time the baby's head is not exposed exceeds a third preset threshold for the head being covered, determine that the baby is in a head-covered condition.

[0085] By determining whether the exposed body parts of the infant include the head, and obtaining the length of time the head is not exposed when the head is not exposed, when the length of time the head is not exposed exceeds the preset length of time, it is determined that the infant is currently in a state of having its head covered, and further reminder operations are taken. This can promptly remind the guardian of the infant's abnormal condition and avoid dangers such as suffocation caused by the infant's head being covered.

[0086] In one embodiment, determining the exposed body part of the infant includes: calculating the perimeter of the connected area; determining the circularity of the connected area based on the area and the perimeter of the connected area; and determining the exposed body part of the infant based on the area and the circularity of the connected area.

[0087] Specifically, the area S of the connected area is first used to calculate the perimeter of the connected area of ​​the exposed body part. The perimeter of the connected area is the total length of the outer boundary pixels of the area S of the connected area, which is defined as P. Then, the circularity C of the connected area is calculated using the area S and the perimeter P of the connected area through the circularity calculation formula. The circularity is an indicator to measure the circularity of the connected area, which is between 0 and 1. The calculation formula of the circularity is:

[0088] C=4π·S / P 2

[0089] When C is 1, the connected area is a circle; the smaller C is, the greater the difference between the connected area and the circle. The circularity C of the connected area can be used to distinguish whether the exposed body part is an arm, a leg or a torso. The circularity of the arm is the smallest, followed by the leg and the torso, and the circularity of the head is the largest. The exposed body part of the baby is determined based on the area of ​​the connected area and the first preset threshold of the preset multiple exposed body parts, as well as the circularity of the connected area and the circularity range of the corresponding body part.

[0090] For example, set the roundness thresholds of the head, arms, legs, and torso to σ respectively. 头部 , σ 手臂 , σ 腿部, σ 躯干 , the body part area threshold is γ 手臂 , γ 腿部 , γ 躯干 , γ 头部 .

[0091] When σ 躯干 < C < σ 头部 , and S > γ 躯干 , determine that the exposed body part is the torso.

[0092] When σ 腿部 < C < σ 躯干 , and S > γ 腿部 , determine that the exposed body part is the leg.

[0093] When σ 手臂 < C < σ 腿部 , and S > γ 手臂 , determine that the exposed body part is the arm.

[0094] When σ 头部 < C < 1, and S > γ 头部 , determine that the exposed body part is the head.

[0095] In one embodiment, the abnormal condition further includes a fever condition; the method further includes: determining whether the temperature array is greater than a preset temperature threshold; if so, determining that the infant has a fever condition.

[0096] In this embodiment, the preset temperature threshold is 37°. When the collected temperature array T ij is greater than 37°, it is determined that the infant has a fever condition, and the guardian needs to take further care, for example, cooling the infant in time or sending the infant to the hospital, etc., to avoid greater harm to the infant's physical health due to delayed illness.

[0097] In one embodiment, after determining that the infant has an abnormal condition, the method further includes: sending body temperature information, real-time video information, and / or alarm information to the user's mobile terminal.

[0098] Specifically, when it is determined that the infant is in an abnormal condition of kicking the quilt, covering the head, or having a fever, the state information of the infant, such as body temperature information, real-time video information, and alarm information, is sent to the guardian's mobile phone through the wireless communication module preset in the crib and an alarm is issued to prompt the caregiver to pay attention. It can remind the guardian in time when an abnormal condition occurs when the infant is sleeping at night or the caregiver is not around, realizing more meticulous and safe care.

[0099] Refer to the appendix Figure 2 , Figure 2It is a schematic diagram of the detailed step process of the baby abnormal condition detection method according to an embodiment of the present invention.

[0103] Step S03: Based on the temperature array T ij construct a binary image of the temperature array.

[0104] Specifically, judge whether T ij is greater than 35. If so, T ij is the first preset value, and the first preset value is 1; if not, then T ij is the second preset value, and the second preset value is 0; take the pixels of the first preset value as foreground pixels and the pixels of the second preset value as background pixels. It can be understood that the pixel color of the first preset value is white and the pixel color of the second preset value is black, and then construct a binary image of the temperature array according to the foreground pixels and background pixels.

[0105] Step S04: Based on the binary image of the temperature array and the one-step labeling method, calculate the area S, perimeter P, and circularity C of the connected region of the baby's exposed body parts respectively.

[0113] Specifically, the roundness threshold σ of the legs and torso is preset 腿部 , σ 躯干 , kicking range threshold γ 腿部 Judgment, when σ 腿部 <C<σ 躯干 When S>γ 腿部 , the exposed part is judged to be the leg.

[0114] Step S10: Determine whether the duration of the baby's legs being exposed exceeds a preset leg exposure time threshold τ 腿部 If yes, execute step S13; if no, execute step S11.

[0115] Step S11: Based on the area S and circularity C of the connected area of ​​the baby's exposed body parts, determine whether the exposed part is an arm. If so, record the length of time the arm is exposed and execute step S12; if not, execute step S14.
