Description

Technical Field

[0001] The embodiments of the present application relate to the field of identification technology, and in particular, to an identification method, apparatus, device and storage medium. Background Art

[0002] For some recognition devices, there is an optimal recognition distance, that is, when the distance between the object to be recognized and the recognition device meets the preset target distance, the recognition device can achieve the best recognition of the object to be recognized. For example, the recognition device includes a camera, and the recognition device obtains the recognition result through the image captured by the camera. At this time, if the object to be recognized is too far away from the camera, the image captured by the camera is darker and smaller. If the object to be recognized is too close to the camera, the image captured by the camera is overexposed or the complete image cannot be captured. It can be seen that when the object to be recognized is far or close to the recognition device, the recognition result will be inaccurate. Therefore, in order to ensure the recognition accuracy of the recognition device, the distance between the object to be recognized and the recognition device needs to meet the target distance.

[0003] Currently, voice or other prompting methods are used to prompt the object to be identified to move so that the distance between the object to be identified and the identification device reaches the target distance. However, in this prompting method, since the moving distance cannot be determined each time the object to be identified moves, the object to be identified needs to move multiple times to reach the target distance, resulting in low recognition efficiency.

[0040] The recognition method provided in the embodiment of the present application can be applied to any scenario that has requirements on the recognition distance, that is, the present application can be applied to any recognition scenario that requires the distance between the object to be recognized and the recognition device to meet the target distance, including but not limited to cloud technology, artificial intelligence, smart transportation, assisted driving, etc.

[0041] In order to facilitate understanding of the embodiments of the present application, an application scenario of the embodiments of the present application is first introduced.

[0042] Figure 1 Schematic diagram of an identification application scenario involved in the embodiment of the present application. Figure 1 As shown, it includes an object to be identified and an identification device. In some embodiments, Figure 1 As shown, the identification device also includes a distance measuring device, a collection device, a wind pressure generator, etc.

[0043] It should be noted that Figure 1 This is just an example, showing that the distance measuring device, the collection device and the wind pressure generator are all installed on the identification device. In some embodiments, at least one of the distance measuring device, the collection device and the wind pressure generator may not be installed on the identification device. In other words, the embodiment of the present application does not limit the specific installation position of the distance measuring device, the collection device and the wind pressure generator, and the identification device, which can be determined according to actual conditions.

[0044] The above-mentioned distance measuring device is used to measure the distance between the object to be identified and the identification device. The embodiment of the present application does not limit the specific type of the distance measuring device, for example, it can be any distance measuring device such as an infrared distance measuring device, a sound wave distance measuring device, a radar distance measuring device, etc.

[0045] The wind pressure generator is used to generate wind pressure acting on the object to be identified. The embodiment of the present application does not limit the specific type of the wind pressure generator. For example, the wind pressure generator includes at least one air outlet, and outputs wind of a certain pressure through the air outlet to act on the object to be identified.

[0046] The acquisition device is used to acquire characteristic information of the object to be identified, such as acquiring an image of the object to be identified. The embodiment of the present application does not limit the specific type of the acquisition device, for example, it can be a scanning device, a camera or other acquisition device.

[0047] The recognition device is used to analyze the characteristic information of the object to be recognized collected by the collection device to obtain the recognition result of the object to be recognized.

[0048] The embodiments of the present application do not limit the specific communication connection method between the ranging device, the collection device, the wind pressure generator and the identification device.

[0049] In some embodiments, if the wind pressure generator has computing capability, the distance measuring device can be connected to the wind pressure generator by communication, for example, by wired or wireless connection. In this way, the distance measuring device can send the measured distance to the wind pressure generator. The wind pressure generator adjusts the wind pressure acting on the object to be identified according to the measured distance, so that the object to be identified moves to the target distance according to the felt wind pressure.

[0050] In some embodiments, the distance measuring device and the identification device are connected in communication, for example, by wired or wireless means. In this way, the distance measuring device can send the measured distance to the identification device, for example, to a processor in the identification device. The identification device determines the wind pressure acting on the object to be identified based on the measured distance, and controls the wind pressure generator to output the wind pressure to the object to be identified, so that the object to be identified moves according to the felt wind pressure, thereby making the distance between the object to be identified and the identification device reach the target distance.

[0051] In some embodiments, the recognition device communicates with the collection device, for example, by wired or wireless connection. When the recognition device determines that the distance between the object to be recognized and the recognition device reaches the target distance, the recognition device controls the collection device to collect feature information of the object to be recognized. The collection device sends the collected feature information to the recognition device, for example, to a processor in the recognition device, and the processor analyzes the collected feature information to obtain a final recognition result.

[0052] The technical solutions of the embodiments of the present application are described in detail below through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0053] Figure 2 A flowchart of an identification method provided in an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0054] S201: Obtain the distance between the object to be identified and the identification device.

[0055] The execution subject of the embodiment of the present application is a device with a specific identification function, hereinafter referred to as an identification device, which can be Figure 1 The identification device shown can also be Figure 1 The part of the identification device shown is, for example, a processor in the identification device.

[0056] For the convenience of description, the following explanation is given by taking the execution subject as an identification device as an example.

[0057] In the embodiment of the present application, during the identification process, the distance between the object to be identified and the identification device is obtained in real time, and the wind pressure acting on the object to be identified is adjusted in real time based on the distance, so that the distance of movement of the object to be identified is controlled under the action of the wind pressure. In the embodiment of the present application, the wind pressure acting on the object to be identified is determined based on the distance between the object to be identified and the identification device, and therefore, the object to be identified can obtain an accurate moving distance based on the wind pressure it feels, so that the object to be identified can move to the target distance in a few moves, thereby improving the recognition efficiency and the recognition performance.

[0058] The embodiments of the present application do not limit the specific type of the object to be identified, which is determined according to the application scenario.

[0059] Exemplarily, the object to be identified may be a part of an object, such as a head, a face, a palm, etc. Optionally, the object to be identified may also be a whole object, such as a whole body, etc.

[0060] The embodiment of the present application does not limit the wake-up method of the identification device.

[0061] In some embodiments, the identification device is turned on by touch. For example, a power button is installed on the identification device, and the identification device is turned on by touching the power button. For another example, the identification device is awakened by touching the touch screen of the identification device.

[0062] After the identification device wakes up, the distance measuring device can measure the distance from the object to be identified located in front of the identification device to the identification device.

[0063] In some embodiments, when the distance measuring device detects that the object to be identified is located directly in front of the identification device and stays there for a preset time, the distance between the object to be identified and the identification device is measured.

[0064] Next, the distance measuring device sends the measured distance between the object to be identified and the identification device at the current moment to the identification device.

[0065] The embodiments of the present application do not limit the specific type of the ranging device. For example, it can be any ranging device such as an infrared ranging device, a sound wave ranging device, a radar ranging device, etc.

[0066] S202: If the distance is not equal to the target distance, the wind pressure acting on the object to be identified is adjusted according to the distance, so that the distance between the object to be identified and the identification device reaches the target distance.

[0067] After the recognition device obtains the distance between the object to be recognized and the recognition device at the current moment, it determines whether the distance between the object to be recognized and the recognition device is equal to the preset target distance. If the distance between the object to be recognized and the recognition device at the current moment is equal to the target distance, the object to be recognized is directly recognized to obtain the recognition result. For example, if the distance between the object to be recognized and the recognition device at the current moment is equal to the target distance, the recognition device controls the acquisition device to collect the characteristic information of the object to be recognized. Then, the acquisition device sends the collected characteristic information to the recognition device for analysis to obtain the recognition result.

[0068] If the distance between the object to be identified and the identification device at the current moment is not equal to the target distance, the identification device adjusts the wind pressure acting on the object to be identified according to the distance between the object to be identified and the identification device at the current moment, so that the object to be identified moves according to the felt wind pressure until the distance between the object to be identified and the identification device reaches the target distance.

[0069] In the embodiment of the present application, the wind pressure acting on the object to be identified is determined according to the distance between the object to be identified and the identification device at the current moment.

[0070] For example, when the object to be identified is far away from the identification device, the wind pressure generator is controlled to generate a large negative wind pressure, which can be understood as the wind pressure that pulls the object closer to the identification device. In this way, the object to be identified moves toward the identification device under the action of the negative wind pressure. In the process of the object to be identified moving toward the identification device, the wind pressure felt by the object to be identified gradually decreases. When the object to be identified moves to the point where it can no longer feel the wind pressure, the object to be identified stops moving.

[0071] For example, when the object to be identified is close to the identification device, the wind pressure generator is controlled to generate a larger positive wind pressure, which can be understood as the wind pressure that pushes the object away from the identification device. In this way, the object to be identified moves away from the identification device under the action of the positive wind pressure. In the process of the object to be identified moving away from the identification device, the wind pressure felt by the object to be identified gradually decreases. When the object to be identified moves to the point where it can no longer feel the wind pressure, the object to be identified stops moving.

[0072] Generally, the object to be identified can be moved to the target distance in one movement according to the wind pressure. Therefore, in some embodiments, the identification device directly identifies the object to be identified without measuring the distance between the object to be identified and the identification device after the movement.

[0073] In some embodiments, in order to further improve the accuracy of recognition, after each movement of the object to be recognized, the distance between the object to be recognized and the recognition device is measured. At this time, the wind pressure acting on the object to be recognized is adjusted according to the distance in S202 so that the distance between the object to be recognized and the recognition device reaches the target distance, which may include the following steps:

[0074] S202-A, adjusting the wind pressure acting on the object to be identified according to the distance;

[0075] S202-B, obtaining the distance between the object to be identified and the identification device when the adjusted wind pressure acts on the object to be identified;

[0076] S202-C: If the distance is not equal to the target distance, the wind pressure acting on the object to be identified continues to be adjusted according to the distance until the distance between the object to be identified and the identification device reaches the target distance.

[0077] In this embodiment, the distance between the object to be identified and the identification device is monitored in real time, and the wind pressure acting on the object to be identified is adjusted in real time according to the real-time monitored distance until the distance between the object to be identified and the identification device reaches the target distance.

[0078] For example, the distance measuring device measures the distance 1 between the object to be identified and the identification device at time t1, and sends the distance 1 to the identification device, and the identification device determines whether the distance 1 is equal to the target distance. If the distance 1 is equal to the target distance, the object to be identified is directly identified. If the distance 1 is not equal to the target distance, the wind pressure generator is controlled according to the distance 1 to adjust the output wind pressure to wind pressure 1. The object to be identified moves to position 1 under the action of wind pressure 1. Next, the distance measuring device measures the distance 2 between the object to be identified at position 1 and the identification device, and sends the distance 2 to the identification device, and the identification device determines whether the distance 2 is equal to the target distance. If the distance 2 is equal to the target distance, the object to be identified is directly identified. If the distance 2 is not equal to the target distance, the wind pressure generator is continued to be controlled according to the distance 2 to adjust the output wind pressure to wind pressure 2. The object to be identified moves to position 2 under the action of wind pressure 2. The distance measuring device measures the distance 3 between the object to be identified at position 2 and the identification device. And so on, until the distance between the object to be identified and the identification device reaches the target distance.

[0079] In this embodiment, after each movement of the object to be identified, it is determined whether the distance between the object to be identified and the identification device after the movement is equal to the target distance. If it is not equal to the target distance, the wind pressure acting on the object to be identified is continuously adjusted according to the distance between the object to be identified and the identification device after the movement, so that the object to be identified continues to move under the action of the wind pressure until the distance between the object to be identified and the identification device reaches the target distance, thereby ensuring that the object to be identified finally moves to the target distance, thereby improving the recognition accuracy.

[0080] The embodiment of the present application does not limit the specific method of adjusting the wind pressure acting on the object to be identified according to the distance.

[0081] In some embodiments, if the object to be identified is far away or close to the identification device, a larger wind pressure can be first applied to the object to be identified so that the object to be identified moves to a preset position range. It is understandable that if the object to be identified moves to the preset position range, the distance between the object to be identified and the identification device is near the target distance. Next, the distance between the object to be identified and the identification device within the preset position range is measured, and the wind pressure acting on the object to be identified is fine-tuned according to the distance, so that the object to be identified moves to the target distance under the action of the fine-tuned wind pressure. That is to say, in this embodiment, the wind pressure acting on the object to be identified is roughly adjusted and fine-tuned according to the distance between the object to be identified and the identification device, so that the object to be identified moves quickly to the target distance from the identification device, thereby increasing the moving speed of the object to be identified.

[0082] In some embodiments, adjusting the wind pressure acting on the object to be identified according to the distance may further include the following steps:

[0083] S202-A1, determining the distance difference between the distance and the target distance;

[0084] S202-A2. Adjust the wind pressure acting on the object to be identified according to the distance difference.

[0085] In this embodiment, the distance difference between the distance between the object to be identified and the identification device measured at the current moment and the target distance is calculated, and then the wind pressure acting on the object to be identified is adjusted according to the distance difference.

[0086] The embodiment of the present application does not limit the specific method of adjusting the wind pressure acting on the object to be identified according to the distance difference in the above S202-A2.

[0087] In some embodiments, the preset wind pressure gear is the corresponding relationship between the distance differences. It should be noted that the corresponding relationship can be obtained through experimental measurement. In this way, the gear corresponding to the distance difference at the current moment can be determined based on the distance between the object to be identified and the identification device measured at the current moment and the distance difference between the target distance, and then the wind pressure can be adjusted to the corresponding gear.

[0088] In one example, one level of wind pressure corresponds to a fixed distance difference, for example, one level of wind pressure corresponds to distance difference a. Thus, if the distance difference between the distance between the object to be identified and the identification device measured at the current moment and the target distance is distance difference b, and distance difference b is c times of distance difference a, the wind pressure generator is controlled to adjust the level of the output wind pressure at the current moment to level c.

[0089] In another example, different distances correspond to different wind pressure levels. For example, the corresponding relationship between the wind pressure level and the distance difference is shown in Table 1:

[0090] Table 1

[0091] Wind pressure level Distance Difference Gear 1 Distance difference 1 Gear 2 Distance Difference 2 …… …… Gear position Distance difference n

[0092] In Table 1, the distance difference refers to the distance between the object to be identified and the identification device, and the distance difference between the distance and the target distance. Among them, if the distance difference is greater than 0, it means that the distance between the object to be identified and the identification device is greater than the target distance. If the distance difference is less than 0, it means that the distance between the object to be identified and the identification device is less than the target distance. In Table 1, different distance differences correspond to different wind pressure gears. In this way, according to the distance difference determined at the current moment, the corresponding wind pressure gear can be queried in the above Table 1, and then the gear of the wind pressure generator can be adjusted to the queried wind pressure gear.

[0093] In some embodiments, the gear position corresponding to the distance difference greater than 0 in the above Table 1 is the gear position corresponding to the negative wind pressure. That is, if the distance from the object to be identified to the identification device at the current moment is greater than the target distance, then according to the distance difference at the current moment, the gear position corresponding to the distance difference is queried in Table 1, and when the wind pressure generator is adjusted according to the gear position, the wind pressure generator outputs negative wind pressure, so that the object to be identified is close to the identification device under the action of the negative wind pressure. The gear position corresponding to the distance difference less than 0 in the above Table 1 is the gear position corresponding to the positive wind pressure. That is, if the distance from the object to be identified to the identification device at the current moment is less than the target distance, then according to the distance difference at the current moment, the gear position corresponding to the distance difference is queried in Table 1, and when the wind pressure generator is adjusted according to the gear position, the wind pressure generator outputs positive wind pressure, so that the object to be identified is away from the identification device under the action of the positive wind pressure. That is to say, in the embodiment shown in Table 1, when adjusting the wind pressure acting on the object to be identified according to the distance difference, regardless of whether the distance difference is greater than 0 or less than 0, the corresponding wind pressure level is directly queried in Table 1, and the wind pressure output by the wind pressure generator is adjusted according to the queried wind pressure level.

[0094] In some embodiments, the wind pressure acting on the object to be identified is adjusted according to whether the distance difference is greater than 0 or less than 0.

[0095] For example, if the distance difference is greater than 0, the wind pressure acting on the object to be identified is adjusted to a negative wind pressure so that the object to be identified is brought closer to the identification device.

[0096] For another example, if the distance difference is less than 0, the wind pressure acting on the object to be identified is adjusted to a positive wind pressure so that the object to be identified is away from the identification device.

[0097] In this embodiment, the wind pressure acting on the object to be identified is adjusted according to whether the distance difference is greater than 0 or less than 0.

[0098] In one example, if the distance difference is greater than 0, it means that the distance between the object to be identified and the identification device at the current moment is greater than the target distance. At this time, the wind pressure generator is controlled to output negative wind pressure to act on the object to be identified, so that the object to be identified moves in the direction close to the identification device under the action of the negative wind pressure, so that the distance between the object to be identified and the identification device is equal to the target distance. In this embodiment, the negative wind pressure output by the wind pressure generator can be adjusted to different gears according to the distance difference. For example, first determine the correspondence between the distance difference and the different gears of negative wind pressure as shown in Table 1 above, and then according to the distance difference at the current moment, obtain the gear of the negative wind pressure corresponding to the distance difference by looking up the table, and adjust the wind pressure generator according to the gear of the negative wind pressure so that the wind pressure generator outputs negative wind pressure, so that the object to be identified is close to the identification device under the action of the negative wind pressure. Of course, other adjustment methods can also be used to adjust the negative wind pressure acting on the object to be identified, and the embodiment of the present application does not limit this.

[0099] In another example, if the distance difference is less than 0, it means that the distance between the object to be identified and the identification device at the current moment is less than the target distance. At this time, the wind pressure generator is controlled to output positive wind pressure to act on the object to be identified, so that the object to be identified moves in the direction away from the identification device under the action of the positive wind pressure, so that the distance between the object to be identified and the identification device is equal to the target distance. In this embodiment, the positive wind pressure output by the wind pressure generator can be adjusted to different gears according to the distance difference. For example, first determine the correspondence between the distance difference and the different gears of positive wind pressure as shown in Table 1 above, and then according to the distance difference at the current moment, obtain the gear of the positive wind pressure corresponding to the distance difference by looking up the table, and adjust the wind pressure generator according to the gear of the positive wind pressure so that the wind pressure generator outputs positive wind pressure, so that the object to be identified is away from the identification device under the action of the positive wind pressure. Of course, other adjustment methods can also be used to adjust the positive wind pressure acting on the object to be identified, and the embodiment of the present application does not limit this.

[0100] In some embodiments, the wind pressure acting on the object to be identified may also be adjusted according to the following steps S202-A21 and S202-A22:

[0101] S202-A21, determining the target wind pressure according to the distance difference;

[0102] S202-A22, adjusting the wind pressure acting on the object to be identified to the target wind pressure.

[0103] In this embodiment, the target wind pressure acting on the object to be identified is directly determined based on the distance difference at the current moment, and then the wind pressure generator is controlled to adjust the wind pressure acting on the object to be identified to the target wind pressure. That is, in this implementation, the target wind pressure is directly determined based on the distance difference instead of determining the wind pressure level, and there is no need to determine the corresponding relationship shown in Table 1, thereby reducing the complexity of identification.

[0104] The specific methods of determining the target wind pressure according to the distance difference in the present application embodiment include but are not limited to the following:

[0105] Method 1, multiply the distance difference by a preset value to obtain a product, and determine the product as the target wind pressure, or process the product, such as correcting the product to obtain the target wind pressure. The predicted value can be understood as the wind pressure adjustment corresponding to a unit (such as 1m) of distance difference. Optionally, the predicted value can be obtained through experiments or is an empirical value. In this way, the target wind pressure can be determined based on the product of the distance difference at the current moment and the preset value.

[0106] Method 2: By determining the pressure adjustment value, the target wind pressure can be determined according to the distance difference and the pressure adjustment value.

[0107] The pressure adjustment value may be an adjustment pressure that can be felt by human power according to actual testing.

[0108] In one example, the pressure adjustment value is a fixed value.

[0109] In another example, the pressure adjustment value is determined according to the attributes corresponding to the object to be identified. For example, assuming that the object to be identified is a palm, the size and force perception of an adult's palm is different from that of a minor's palm, so a pressure adjustment value is set for adults and a pressure adjustment value is set for minors. In some embodiments, a more detailed division can be achieved for different attributes, such as setting different pressure adjustment values ​​for different age groups and different genders. In this way, the pressure adjustment value corresponding to the object to be identified can be determined based on the attributes corresponding to the object to be identified. When determining the target wind pressure based on the pressure adjustment value corresponding to the object to be identified and the distance difference, the accuracy of determining the target wind pressure can be improved.

[0110] The embodiment of the present application does not limit the specific method of determining the target wind pressure based on the distance difference and the pressure adjustment value in the above-mentioned method 2.

[0111] In a possible implementation, the product of the distance difference and the pressure adjustment value is determined as the target wind pressure.

[0112] In another possible implementation, first determine the first wind pressure value based on the distance difference and the pressure adjustment value; determine the second wind pressure value based on the preset sensitivity and the force area of ​​the object to be identified; and determine the target wind pressure based on the first wind pressure value and the second wind pressure value.

[0113] In this implementation, in the process of determining the target wind pressure, the wind pressure required to overcome the resistance of the object to be identified is taken into account. In this embodiment, the wind pressure required to overcome the resistance of the object to be identified is recorded as the second wind pressure. In this way, when determining the target wind pressure, first, according to the distance difference and the pressure adjustment value, the first wind pressure value is determined, for example, the product of the distance difference and the pressure adjustment value is determined as the first wind pressure value, or the product of the distance difference and the pressure adjustment value is adjusted, multiplied or divided by a certain coefficient, and the adjusted product is determined as the first wind pressure value.

[0114] Next, the second wind pressure value is determined according to the preset sensitivity and the force-bearing area of ​​the object to be identified. The embodiment of the present application does not limit the specific size of the preset sensitivity, for example, the preset sensitivity is equal to the reverse force of the gravity of the object to be identified. Exemplarily, if the object to be identified is a palm, the sensitivity is the sensitivity of human power when the palm is placed horizontally. In one example, the sensitivity is a fixed value, and in one example, the sensitivity can be determined according to the attribute corresponding to the object to be identified. For example, assuming that the object to be identified is a palm, the size and force perception of the palm of an adult and the palm of a minor are different, so a sensitivity is set for adults and a sensitivity is set for minors. In some embodiments, more detailed divisions can be achieved for different attributes, such as setting different sensitivity for different age groups and different genders. In this way, the sensitivity corresponding to the object to be identified can be determined according to the attribute corresponding to the object to be identified. When the second wind pressure value is determined according to the sensitivity corresponding to the object to be identified and the force-bearing area of ​​the object to be identified, the accuracy of determining the second wind pressure value can be improved.

[0115] In the embodiment of the present application, there is no limitation on the specific method of determining the second wind pressure value according to the preset sensitivity and the force-bearing area of ​​the object to be identified.

[0116] In one example, the ratio of the sensing force to the force-bearing area of ​​the object to be identified is determined as the second wind pressure value.

[0117] In another example, the drag coefficient corresponding to the object to be identified is determined; the product between the drag coefficient and the force-bearing area of ​​the object to be identified is determined; and the ratio between the sensing force and the product is determined as the second wind pressure value. The drag coefficient is used to indicate that when the object to be identified is in relative motion with the air, the object to be identified will be subject to air resistance. The embodiment of the present application does not limit the specific method of determining the drag coefficient corresponding to the object to be identified, and it can be calculated by referring to any existing method of calculating the drag coefficient.

[0118] According to the above steps, the first wind pressure value and the second wind pressure value are determined, and the target wind pressure is determined according to the first wind pressure value and the second wind pressure value. For example, the sum of the first wind pressure value and the second wind pressure value is determined as the target wind pressure. For another example, different weights are set for the first wind pressure value and the second wind pressure value, and then the first wind pressure value and the second wind pressure value are weighted to obtain the target wind pressure. Other similar methods can also be used to process the first wind pressure value and the second wind pressure value to obtain the target wind pressure. The embodiment of the present application does not limit the specific method of determining the target wind pressure according to the first wind pressure value and the second wind pressure value.

[0119] In one example, the target wind pressure is determined according to the following formula (1):

[0120] P=L*Fa+(f / (A*Cd)) (1)

[0121] Where P is the target wind pressure, L*Fa is the first wind pressure value, and f / (A*Cd) is the second wind pressure value. L is the distance difference, Fa is the pressure adjustment value, f is the sensitivity, A is the force area of ​​the object to be identified, Cd is the resistance coefficient corresponding to the object to be identified, and "*" represents the multiplication sign and " / " represents the division sign.

[0122] In the embodiment of the present application, according to the above steps, after the target wind pressure is determined, the wind pressure acting on the object to be identified is adjusted to the target wind pressure.

[0123] In the embodiment of the present application, the specific method of adjusting the wind pressure acting on the object to be identified to the target wind pressure is not limited, and is specifically determined according to the wind pressure adjustment method of the wind pressure generator.

[0124] In some embodiments, if the wind pressure generator can directly adjust the output wind pressure according to the target wind pressure, then the wind pressure generator can be directly controlled to output the target wind pressure. For example, the recognition device sends the target wind pressure to the wind pressure generator, and the controller in the wind pressure generator controls the wind pressure generator to output the target wind pressure.

[0125] In some embodiments, the wind pressure generator adjusts the output wind pressure by adjusting the output wind speed. At this time, the above-mentioned adjusting the wind pressure acting on the object to be identified to the target wind pressure includes: determining the target wind speed according to the target wind pressure; and adjusting the wind pressure acting on the object to be identified to the target wind pressure by adjusting the wind speed to the target wind speed.

[0126] There is a corresponding relationship between wind pressure and wind speed. For example, Table 2 shows the correspondence between wind level, wind speed and wind pressure:

[0127] Table 2

[0128]

[0129]

[0130] In some embodiments, the target wind speed corresponding to the target wind pressure can be queried in Table 2 according to the corresponding relationship between wind pressure and wind speed shown in Table 2.

[0131] In some embodiments, the corresponding target wind speed can be calculated by the target wind pressure.

[0132] Wind pressure is the pressure exerted by the wind on a plane perpendicular to the airflow direction. The relationship between wind pressure and wind speed is derived from the Bernoulli equation. Among them, wind pressure is also called the dynamic pressure of wind.

[0133] In one example, the relationship between wind pressure and wind speed is shown in formula (2):

[0134] P=0.5·ρ·v 2 (2)

[0135] Where P is wind pressure [kN / m2], ρ is air density [kg / m3], and v is wind speed [m / s]. Since the relationship between air density (ρ) and gravity (r) is r = ρ·g, ρ = r / g. Using this relationship in formula (2), the relationship between wind pressure and wind speed is shown in formula (3):

[0136] P=0.5·r·v 2 / g (3)

[0137] Under standard conditions (air pressure is 1013hPa, temperature is 15℃), air weight r=0.01225[kN / m3]. Gravity acceleration at latitude of 45° is g=9.8[m / s2]. Therefore, the relationship between wind pressure and wind speed can be simplified as shown in formula (4):

[0138] P=v 2 / 1600 (4)

[0139] It should be noted that air weight and gravitational acceleration vary with latitude and altitude. Generally speaking, ρ is smaller on plateaus than on plains, which means that the same wind speed at the same temperature will produce less wind pressure on plateaus than on plains.

[0140] In this way, the target wind speed corresponding to the target wind pressure can be calculated according to the relationship between wind pressure and wind speed shown in the above formulas (2) to (4), and then the wind speed of the wind pressure generator can be adjusted to the target wind speed to achieve the regulation of the wind pressure output by the wind pressure generator.

[0141] In an embodiment of the present application, if the distance between the object to be identified and the identification device is not equal to the target distance, the wind pressure acting on the object to be identified is adjusted based on the distance through the above method so that the distance between the object to be identified and the identification device reaches the target distance.

[0142] In some embodiments, on the basis of adjusting the wind pressure acting on the object to be identified according to the distance, voice can also be used to assist in reminding the distance. For example, if the object to be identified is far away from the identification device, that is, when the distance difference between the object to be identified and the identification device and the target distance is greater than 0, a sound of the first frequency is emitted to remind the object to be identified to approach the identification device. If the object to be identified is close to the identification device, that is, when the distance difference between the object to be identified and the identification device and the target distance is less than 0, a sound of the second frequency is emitted to remind the object to be identified to stay away from the identification device. In this way, on the basis of adjusting the wind pressure according to the distance, combined with language reminders of the distance between the object to be identified and the identification device, the object to be identified can be further quickly moved to the target distance, thereby further improving the recognition efficiency.

[0143] S203, identifying the object to be identified within the target distance of the distance identification device to obtain an identification result.

[0144] For example, when the distance between the object to be identified and the identification device is determined to be the target distance, the acquisition device is controlled to collect feature information of the object to be identified to obtain feature information of the object to be identified. Then, the feature information of the object to be identified is identified to obtain an identification result.

[0145] In one example, if the object to be identified is a palm, when it is determined that the palm is at the target distance, the acquisition device (e.g., a camera) is controlled to acquire an image of the palm. Then, the acquired palm image is analyzed, for example, the palm image is compared with a stored palm image. If the acquired palm image matches a stored palm image, the recognition result is successful. If the acquired palm image matches each stored palm image, the recognition result is failed.

[0146] The identification method provided in the embodiment of the present application obtains the distance between the object to be identified and the identification device; if the distance is not equal to the target distance, the wind pressure acting on the object to be identified is adjusted according to the distance so that the distance between the object to be identified and the identification device reaches the target distance; the object to be identified whose distance to the identification device is the target distance is identified to obtain an identification result. In the embodiment of the present application, the wind pressure acting on the object to be identified is determined according to the distance between the object to be identified and the identification device. Therefore, the object to be identified can obtain an accurate moving distance according to the felt wind pressure. In this way, the object to be identified can be moved to the target distance through a few movements, thereby improving the recognition efficiency and the recognition performance.

[0147] Figure 3 A flowchart of an identification method provided in an embodiment of the present application, such as Figure 3 As shown, the method comprises the following steps:

[0148] S301, identification preparation.

[0149] In the embodiment of the present application, identification preparation can be understood as turning on the identification device, and the object to be identified is located directly in front of the identification device.

[0150] S302: Obtain the distance between the object to be identified and the identification device.

[0151] For example, the distance measuring device is controlled to measure the distance between the object to be identified and the identification device.

[0152] S303: Determine whether the distance is equal to the target distance.

[0153] If the distance is equal to the target distance, the following step S316 is executed.

[0154] If the distance is not equal to the target distance, the following step S304 is executed.

[0155] S304: Determine the distance difference between the distance and the target distance.

[0156] S305: Determine whether the distance difference is less than 0.

[0157] If the distance difference is less than 0, the following steps S306 to S309 are executed.

[0158] If the distance difference is greater than 0, the following steps S310 to S313 are executed.

[0159] S306 , determining a target wind pressure according to the distance difference, and controlling the wind pressure generator to generate a positive wind pressure of the target wind pressure to act on the object to be identified, so as to keep the object to be identified away from the identification device.

[0160] If the distance difference is less than 0, it means that the object to be identified is close to the identification device. At this time, positive wind pressure needs to be generated to keep the object to be identified away from the identification device.

[0161] In the embodiment of the present application, the specific method of determining the target wind pressure based on the distance difference is not limited.

[0162] Exemplarily, the pressure adjustment value is determined; the target wind pressure is determined according to the distance difference and the pressure adjustment value. For example, a first wind pressure value is determined according to the distance difference and the pressure adjustment value; a second wind pressure value is determined according to a preset sensitivity and a force-bearing area of ​​the object to be identified; and the target wind pressure is determined according to the first wind pressure value and the second wind pressure value.

[0163] Among them, the specific method of determining the target wind pressure according to the distance difference can refer to the specific implementation method of the above S202-A1, which will not be repeated here.

[0164] After the identification device determines the target wind pressure, the wind pressure generator is controlled to output a positive wind pressure whose output value is the target wind pressure to act on the object to be identified, so as to keep the object to be identified away from the identification device.

[0165] S307: Determine whether the distance between the object to be identified and the identification device increases.

[0166] S308. Increase positive wind pressure.

[0167] S309. Reduce positive wind pressure.

[0168] In the embodiment of the present application, the distance between the object to be identified and the identification device is monitored in real time, and the wind pressure is adjusted in real time according to the distance. For example, it is determined whether the distance between the object to be identified and the identification device increases. If it increases, the positive wind pressure is reduced. If the distance between the object to be identified and the identification device does not increase, the positive wind pressure is increased.

[0169] S310: Determine a target wind pressure according to the distance difference, and control a wind pressure generator to generate a negative wind pressure of the target wind pressure to act on the object to be identified, so that the object to be identified is close to the identification device.

[0170] If the distance difference is greater than 0, it means that the object to be identified is far away from the identification device. At this time, negative wind pressure needs to be generated to bring the object to be identified closer to the identification device.

[0171] In the embodiment of the present application, the specific method of determining the target wind pressure according to the distance difference can refer to the specific implementation method of S202-A1 above, which will not be repeated here.

[0172] After the identification device determines the target wind pressure, the wind pressure generator is controlled to output a negative wind pressure of the target wind pressure to act on the object to be identified, so that the object to be identified is brought close to the identification device.

[0173] S311: Determine whether the distance between the object to be identified and the identification device is reduced.

[0174] S312. Increase negative wind pressure.

[0175] S313. Reduce negative wind pressure.

[0176] In the embodiment of the present application, the distance between the object to be identified and the identification device is monitored in real time, and the wind pressure is adjusted in real time according to the distance. For example, it is determined whether the distance between the object to be identified and the identification device is reduced. If it is reduced, the negative wind pressure is reduced. If the distance between the object to be identified and the identification device is not reduced, the negative wind pressure is increased.

[0177] In some embodiments, on the basis of adjusting the wind pressure acting on the object to be identified according to the distance, voice can also be used to assist in reminding the distance. For example, if the distance difference is greater than 0, a sound of the first frequency is emitted to remind the object to be identified to approach the identification device. If the distance difference is less than 0, a sound of the second frequency is emitted to remind the object to be identified to stay away from the identification device. In this way, on the basis of adjusting the wind pressure according to the distance, combined with language reminders of the distance between the object to be identified and the identification device, the object to be identified can be further quickly moved to the target distance, thereby further improving the recognition efficiency.

[0178] S314: Determine whether the distance between the object to be identified and the identification device is equal to the target distance.

[0179] After the above adjustment, it is determined whether the distance between the object to be identified and the identification device is equal to the target distance after the object to be identified moves. If the distance between the object to be identified and the identification device is equal to the target distance, the following steps S315 and S316 are executed.

[0180] If the distance between the object to be identified and the identification device is not equal to the target distance, the above step S304 is executed.

[0181] S315, controlling the wind pressure generator to stop outputting wind pressure.

[0182] S316: Identify the object to be identified and obtain an identification result.

[0183] The specific implementation method of the above S316 is the same as the specific implementation method of the above S203, which will not be repeated here.

[0184] In the embodiment of the present application, the distance between the object to be identified and the identification device is measured in real time, and the wind pressure acting on the object to be identified is adjusted in real time according to the real-time measured distance, so that the object to be identified can be quickly and accurately moved to the distance identification device, thereby improving the identification efficiency and accuracy.

[0185] The following uses the palm as an example of the object to be identified to introduce the identification method provided in the embodiment of the present application.

[0186] Figure 4 A schematic diagram of an identification device provided in an embodiment of the present application, such as Figure 4 As shown, the recognition device can be called a palm brushing device. The recognition device includes a wind pressure generator and a palm brushing camera, wherein the wind pressure generator includes a plurality of air outlets, and exemplarily, the air outlets of the wind pressure generator are located around the palm brushing camera.

[0187] Figure 5 A flowchart of an identification method provided in an embodiment of the present application, such as Figure 5 As shown, the method comprises the following steps:

[0188] S501: Obtain the distance between the palm and the recognition device.

[0189] The specific implementation process of the above S501 refers to the description of the above S201 and will not be repeated here.

[0190] S502: Determine whether the distance is equal to the target distance.

[0191] If the distance is equal to the target distance, step S504 is executed.

[0192] If the distance is not equal to the target distance, step S503 is executed.

[0193] S503: adjusting the wind pressure acting on the palm according to the distance so that the distance between the palm and the recognition device reaches the target distance.

[0194] Exemplarily, the distance difference between the distance and the target distance is determined; and based on the distance difference, the wind pressure acting on the object to be identified is adjusted.

[0195] For example, if the distance difference is greater than 0, the wind pressure acting on the palm is adjusted to negative wind pressure so that the object to be identified is closer to the identification device;

[0196] For another example, if the distance difference is less than 0, the wind pressure acting on the palm is adjusted to positive wind pressure to keep the object to be identified away from the identification device.

[0197] In some embodiments, on the basis of adjusting the wind pressure according to the distance difference, the distance can also be reminded by voice assistance. For example, if the distance difference is greater than 0, a sound of the first frequency is emitted to remind the palm to approach the recognition device, and if the distance difference is less than 0, a sound of the second frequency is emitted to remind the palm to move away from the recognition device. In this way, on the basis of adjusting the wind pressure according to the distance, combined with language reminders of the distance between the palm and the recognition device, the palm can be further moved to the target distance quickly, thereby further improving the recognition efficiency.

[0198] S504: Identify the palm at the target distance from the distance recognition device to obtain a recognition result.

[0199] For example, if the recognition device determines that the distance between the palm and the recognition device is the target distance, the palm-swiping camera is controlled to turn on to collect the palm image, and then the collected palm image is analyzed to obtain the recognition result.

[0200] In an embodiment of the present application, the wind pressure acting on the palm is adjusted by adjusting the distance between the palm and the recognition device, so that the object to be identified moves under the action of the wind pressure, so that the distance between the object to be identified and the recognition device reaches the target distance, thereby improving the palm brushing efficiency.
