Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
Example 1
The embodiment 1 of the invention provides a method for acquiring spatial information. Fig. 1 is a flowchart of a method of acquiring spatial information according to embodiment 1 of the present application. As shown in fig. 1, the method includes:
step 101: acquiring data of a moving part of equipment in a space through an electromagnetic wave sensor, and acquiring distance data representing the distance between the moving part and the electromagnetic wave sensor and angle data representing the angle of the moving part and the electromagnetic wave sensor in a specified time; and
Step 102: and generating the height information of the space according to the distance data and the angle data.
According to the above embodiment, by performing data acquisition on the moving parts of the equipment in the space using the electromagnetic wave sensor, the height information of the space is generated from the distance data and the angle data acquired in the prescribed time, whereby, for example, the problem of privacy leakage caused by using the camera can be avoided, and since the depth uses the electromagnetic wave sensor that detects the approach of the person, the cost of acquiring the height information can be reduced, and the accuracy of the height information can be improved.
In some embodiments, the space may be various indoor spaces, such as a room, office, conference room, classroom, stadium, restaurant, mall, and the like.
In some embodiments, the device may be various devices for use indoors, such as an air treatment device.
In some embodiments, the moving component may be a component that performs periodic movement. Therefore, when detection is performed by the electromagnetic wave sensor, the received signal reflected by the moving member exhibits a periodic echo characteristic. Since other moving bodies in the space, for example, living bodies, do not have a rule of periodic movement, moving parts in the space can be distinguished from other moving bodies according to echo characteristics of a received signal of the electromagnetic wave sensor, so that a detection result is more accurate. However, the present application is not limited thereto, and the moving member may be a member having another movement law as long as it can be distinguished from the non-detection object.
In some embodiments, the moving part may be disposed at or near the top of the space. Thereby, the height information of the space can be acquired by detecting the height of the moving member.
In some embodiments, for an air treatment device disposed within a space, for example, the moving component may be at least one of the following components of the air treatment device: wind pendulum, fan, air outlet's ribbon.
In some embodiments, the electromagnetic wave sensor may be a doppler effect based electromagnetic wave sensor; the electromagnetic wave sensor may be a microwave sensor.
In some embodiments, the electromagnetic wave sensor may be various electromagnetic wave sensors capable of detecting moving parts, for example, may be one of a pulsed doppler radar, a frequency modulated continuous wave radar, and a multi-frequency continuous wave radar. However, the present application is not limited thereto, and the electromagnetic wave sensor may be other types of sensors.
In addition, the specific principle of obtaining the distance data and the angle data based on the detection of the moving component by the electromagnetic wave sensor may refer to the related art, and will not be described herein.
In some embodiments, in step 102, the coordinate system may be utilized to generate altitude information for the space from the distance data and the angle data. Fig. 2 is a flow chart of a method of implementing step 102 of embodiment 1 of the present application. As shown in fig. 2, step 102 may include:
Step 201: setting a coordinate system and a coordinate origin;
step 202: converting the distance data and the angle data into coordinate information of coordinate points; and
step 203: and determining the height information of the space according to the coordinate information of the coordinate points.
In some embodiments, the coordinate system may be various coordinate systems, e.g., it may be a cartesian coordinate system or an angular coordinate system, etc.; as another example, it may be a two-dimensional coordinate system or a three-dimensional coordinate system, etc., such as a two-dimensional rectangular coordinate system, a three-dimensional rectangular coordinate system, a polar coordinate system, a spherical coordinate system, or the like.
In some embodiments, the origin of the coordinates may be the location point where the electromagnetic wave sensor is located. Thus, coordinate information can be more conveniently calculated from the distance data and the angle data. However, the present application is not limited thereto, and the origin of coordinates may be other position points.
In some embodiments, in step 202, the distance data and the angle data of the moving part with respect to the electromagnetic wave sensor, the origin of coordinates, and the position of the coordinate axes may be converted into coordinate information of the moving part in a coordinate system.
In some embodiments, in step 203, in the case where the direction of one coordinate axis of the coordinate system is the same as the height direction, the height information of the space may be calculated from the coordinate information of the moving part on the coordinate axis. For example, in the case where the electromagnetic wave sensor is located on the ground and the moving member is located on the top of the space, the height of the space may be the coordinate value of the moving member on the coordinate axis. For another example, in the case where the electromagnetic wave sensor is located at a preset height and the moving member is located at the top of the space, the height of the space may be the sum of the coordinate value of the moving member on the coordinate axis and the preset height.
The coordinate information may be corrected according to actual conditions to obtain spatial height information. For example, in the case where the electromagnetic wave sensor is located on the ground, the device is located near the top of the space, and the moving member is located at the lower part of the device (for example, the device is a wall-mounted air conditioner, the moving member is a wind pendulum located at the lower side of the wall-mounted air conditioner, or the like), the height of the space may be the sum of the coordinate value of the moving member on the coordinate axis and the height of the device. For another example, in the case where the electromagnetic wave sensor is located at a preset height, the apparatus is located near the top of the space, and the moving member is located at the lower part of the apparatus, the height of the space may be the sum of the coordinate value of the moving member on the coordinate axis, the height of the apparatus, and the preset height.
In some embodiments, in steps 101 and 102, spatial elevation information may be generated using distance data and angle data acquired over one or more longitudinal detection ranges.
In some embodiments, one electromagnetic wave sensor may be provided, or a plurality of electromagnetic wave sensors may be provided.
For example, an electromagnetic wave sensor may have a longitudinal detection range, and the height information may be calculated based on the detection result within the longitudinal detection range. Alternatively, one electromagnetic wave sensor may have a plurality of longitudinal detection ranges, and the height information may be calculated based on the detection results in the plurality of longitudinal detection ranges. For example, the electromagnetic wave sensor may be located at a certain height in space (e.g., a height of 1m, 1.5m, 1.8m, etc. from the ground), and the plurality of intersecting longitudinal detection regions may be formed by rotating the electromagnetic wave sensor.
For another example, a plurality of electromagnetic wave sensors may correspond to a plurality of intersecting longitudinal detection ranges, and the height information may be calculated from detection results within the plurality of longitudinal detection ranges. For example, at a certain height in space (for example, a height of 1m, 1.5m, 1.8m, etc. from the ground), a plurality of electromagnetic wave sensors are installed, by which a plurality of intersecting longitudinal detection ranges are formed. Alternatively, a plurality of electromagnetic wave sensors are installed at a plurality of heights in space (for example, a height of 1m, 1.5m, 1.8m, etc. from the ground), thereby forming a plurality of intersecting longitudinal detection ranges.
In some embodiments, the longitudinal detection range of one electromagnetic wave sensor may include a first detection range and a second detection range different from the first detection range. Wherein the electromagnetic wave sensor has higher detection accuracy and/or higher detection sensitivity for moving parts located in the first detection range than for moving parts located in the second detection range. For example, the distance data and the angle data acquired in the first detection range are more accurate than the distance data and the angle data acquired in the second detection range; or the distance data and the angle data of the moving part can be acquired in the first detection range, and the distance data and the angle data of the moving part can not be acquired in the second detection range.
In some embodiments, the first detection range of the electromagnetic wave sensor may be a range having a generally conical shape and a predetermined conical angle with a vertex at which the electromagnetic wave sensor is located, and the second detection range may be a certain range located at a periphery of the first detection range.
In some embodiments, the moving part may be judged to be in the first detection range or in the second detection range according to the received signal of the electromagnetic wave sensor. For example, when the intensity of the received signal of the electromagnetic wave sensor is greater than a predetermined value, it is determined that the moving member is located within the first detection range, and otherwise, it is determined that the moving member is located within the second detection range. Alternatively, the determination may be made based on angle data generated by the received signal, for example, when the angle data is smaller than the taper angle of the first detection range, it is determined that the moving member is within the first detection range, or else it is determined that the moving member is within the second detection range.
Additionally, in some embodiments, the moving component may perform a position-changing motion, e.g., a reciprocating motion. Thus, the following may be present: the moving part is located within the first detection range during the whole movement; alternatively, the moving member is located within the first detection range during part of the movement and within the second detection range during part of the movement; alternatively, the moving part is located within the second detection range during the entire movement.
In some embodiments, in the case where the moving part is located within the first detection range throughout the movement period, the distance data and the angle data detected by the electromagnetic wave sensor within the first detection range may be used to generate the height information of the space, that is, the height information of the space is generated from the distance data and the angle data acquired within one longitudinal detection range. However, the present application is not limited thereto, and even when the moving member is located in the first detection range, for example, the calculation of the height information may be performed in combination with the detection results in other longitudinal detection ranges, thereby further improving the accuracy of the calculated height information. The plurality of longitudinal detection ranges may be obtained in accordance with the manner as described above, for example, by providing a plurality of electromagnetic wave sensors or rotating one electromagnetic wave sensor to obtain a plurality of intersecting longitudinal detection ranges.
In some embodiments, in the case that the moving part is located in the second detection range during part or the whole movement, the accuracy of the detected data obtained in the second detection range is low or the detected data is missing in the second detection range due to low detection sensitivity, so that the distance data and the angle data acquired in other longitudinal detection ranges can be combined to generate the spatial height information, thereby being capable of improving the accuracy of the calculated height information. Wherein the plurality of longitudinal detection ranges may be obtained in accordance with the manner as described above, for example, by providing a plurality of electromagnetic wave sensors or rotating one electromagnetic wave sensor to obtain a plurality of intersecting longitudinal detection ranges.
Fig. 3 is another flowchart of a method of implementing step 102 of embodiment 1 of the present application. In some embodiments, when generating height information of a space from distance data and angle data acquired within at least 2 intersecting longitudinal detection ranges, as shown in fig. 3, step 102 may include:
The method of generating the height information in step 301 may refer to the method shown in fig. 2, that is, the height information is calculated using a coordinate system, but the present application is not limited thereto, and the height information may be generated in other ways.
In step 302, when generating the height information of the space from the height information corresponding to each longitudinal detection range, calculation such as averaging or weighting may be performed on each height information, and the calculation result may be regarded as the height information of the space. The weighting value corresponding to each height information can be set according to the actual situation.
For example, the weighting value may be set according to the power of the received signal of the electromagnetic wave sensor, and when the received signal power of the electromagnetic wave sensor in one longitudinal detection range is large, the weighting value of the height information corresponding to the longitudinal detection range may be set to be large. For another example, the weight value may be set based on the received signal angle data (angle of the moving member with respect to the electromagnetic wave sensor), and when the angle of the moving member with respect to the electromagnetic wave sensor is smaller than a certain angle, the weight value of the height information corresponding to the longitudinal detection range may be set to be large.
Fig. 4 is another flowchart of a method of implementing step 102 of embodiment 1 of the present application. In some embodiments, when generating height information of a space from distance data and angle data acquired within at least 2 intersecting longitudinal detection ranges, as shown in fig. 4, step 102 may include:
In step 401, for example, when the distance data and the angle data acquired in the plurality of longitudinal detection ranges are synthesized, the distance data and the angle data may be synthesized according to the positional relationship between the plurality of longitudinal detection ranges. For example, when a plurality of longitudinal detection ranges are formed by rotating the electromagnetic wave sensor, the plurality of distance data may be averaged or weighted according to the angle between the plurality of longitudinal detection ranges to obtain synthesized distance data, and the plurality of angle data may be averaged or weighted to obtain synthesized angle data. When a plurality of electromagnetic wave sensors are provided to form a plurality of vertical detection ranges, the plurality of distance data may be averaged or weighted according to the distance between the plurality of electromagnetic wave sensors and the angle between the plurality of vertical detection ranges to obtain synthesized distance data, and the plurality of angle data may be averaged or weighted to obtain synthesized angle data.
In step 402, the manner in which the height information is generated may be referred to as that shown in fig. 2, that is, the height information is calculated using a coordinate system.
Fig. 5 is another flowchart of a method of acquiring spatial information according to embodiment 1 of the present application. As shown in fig. 5, the method includes:
According to the above embodiment, the three-dimensional information of the space can be generated from the height information and the lateral section information of the space, and since the height information is generated from the distance data and the angle data acquired in the prescribed time by the electromagnetic wave sensor which performs data acquisition on the moving parts of the equipment in the space, the electromagnetic wave sensor itself can also be used for detection of the approach of a conventional person, the cost of acquiring the three-dimensional information of the space can be reduced and the accuracy of the three-dimensional information of the space can be improved by the depth utilization of one kind of sensor.
Step 501 and step 502 may refer to step 101 and step 102, and are not described herein.
For steps 503 and 504, in some embodiments, detection may be performed using one or more electromagnetic wave sensors, and lateral cross-sectional information of the space is obtained from the detected data, thereby generating three-dimensional information of the space.
For example, data detection may be performed using one electromagnetic wave sensor, and three-dimensional information of a space may be generated from the detected data. For example, the detection direction and detection range thereof can be changed by rotating the electromagnetic wave sensor. The electromagnetic wave sensor can detect living bodies in a transverse section of a space and moving parts of equipment in a longitudinal section, can generate transverse section information of the space according to first distance data and first angle data of the living bodies relative to the electromagnetic wave sensor in a specified time, and can generate height information of the space according to second distance data and second angle data of the moving parts relative to the electromagnetic wave sensor in the specified time. In the case where one detection range of the electromagnetic wave sensor can cover a lateral cross section and a height range of a space, three-dimensional information of the space can be generated from the first distance data, the first angle data, the second distance data, and the second angle data within the detection range. In addition, the electromagnetic wave sensor may be rotated to form a plurality of detection ranges capable of covering a lateral cross section and a height range of the space, and three-dimensional information of the space may be generated based on the first distance data, the first angle data, the second distance data, and the second angle data within the plurality of detection ranges.
For example, data detection may be performed using a plurality of electromagnetic wave sensors, and three-dimensional information of a space may be generated from the detected data. For example, a living body in a lateral cross section of a space may be detected by one electromagnetic wave sensor, and lateral cross section information of the space may be generated based on first distance data and first angle data of the living body with respect to the electromagnetic wave sensor within a predetermined time; the moving member in the longitudinal section of the space is detected by another electromagnetic wave sensor, and the height information of the space is generated based on the second distance data and the second angle data of the moving member with respect to the electromagnetic wave sensor in a predetermined time.
In the embodiment of the invention, a specific method for generating the transverse section information of the space according to the first distance data and the first angle data of the organism relative to the electromagnetic wave sensor in the specified time is that, for example, the position point and/or the motion track of the organism in the specified time are determined according to the first distance data and the first angle data; and determining transverse section information according to the position point and/or the motion track of the organism in the specified time.
In some embodiments, the electromagnetic wave sensor may be various sensors capable of detecting movement of moving parts, for example, the electromagnetic wave sensor may be an electromagnetic wave sensor based on the doppler effect. On the one hand, the moving parts can be accurately detected by the electromagnetic wave sensor based on the doppler effect, and on the other hand, the electromagnetic wave sensor based on the doppler effect is arranged in the application device (for example, an air processing device or the like), so that the data can be acquired by utilizing the original electromagnetic wave sensor in the device, and the hardware cost of the application device is not increased.
In some embodiments, the electromagnetic wave sensor is a microwave sensor. The electromagnetic wave emitted by the electromagnetic wave sensor has a frequency range of 5GHz or more. Since the detection accuracy of the electromagnetic wave sensor is higher as the frequency of the electromagnetic wave is higher, for example, millimeter-sized detection can be performed using an electromagnetic wave of 77GHz, the detection accuracy of the electromagnetic wave sensor can be ensured by setting the frequency range of the electromagnetic wave emitted from the electromagnetic wave sensor to 5GHz or more.
In some embodiments, the electromagnetic wave sensor operates at a frequency in the range of 5GHz-80GHz. For example, the operating frequency of the electromagnetic wave sensor may be 5.8GHz or 24GHz or 77GHz.
In some embodiments, the electromagnetic wave sensor may have at least 1 transmit antenna and at least 2 receive antennas. By providing at least 2 receiving antennas, detection of the angle of the moving part can be achieved by the phase difference of the echo signals.
In some embodiments, the electromagnetic wave sensor may be a single point sensor or a multipoint sensor. The single-point sensor can detect the movement of one moving part at the same time, and the cost is low. The multipoint sensor can detect the activities of a plurality of moving parts at the same time, so that compared with the single-point sensor, the multipoint sensor can acquire more data in the same time length, thereby shortening the time for acquiring the space information and improving the detection efficiency.
In some embodiments, the electromagnetic wave sensor may perform data acquisition within a prescribed time. For example, it may collect motion data for moving parts of the device over a prescribed length of time (hours, days, weeks, etc.). For another example, the electromagnetic wave sensor may acquire data in a predetermined period, that is, after completing data acquisition for a predetermined period of time, the electromagnetic wave sensor may acquire data again for a predetermined period of time after a lapse of time, so that the spatial information can be known dynamically.
In some embodiments, the electromagnetic wave sensor may be fixedly disposed in the space. Since the electromagnetic wave sensor itself does not need to be moved, the electromagnetic wave sensor can be applied to various application scenes. However, the present application is not limited to this, and the electromagnetic wave sensor may be a sensor that performs data acquisition by itself movement.
In some embodiments, the electromagnetic wave sensor may be disposed at the bottom of the space or at a preset height. In the case where the electromagnetic wave sensor is provided at the bottom of the space, since the height of the electromagnetic wave sensor itself is negligible, the distance data and the angle data detected by the electromagnetic wave sensor can directly reflect the height information of the space. In this case, the electromagnetic wave sensor may be a device independently provided at the bottom of the space, or it may be provided in other devices on the ground.
In the case where the electromagnetic wave sensor is disposed at a preset height in space, it is also necessary to supplement the preset height at which the electromagnetic wave sensor is disposed on the basis of one of the height information calculated using the detected distance data and angle data. Since the electromagnetic wave sensor has a certain preset height, the distance between the electromagnetic wave sensor and the moving parts of the equipment at or near the top of the room is smaller, and the detected distance data and angle data are more accurate. In this case, the electromagnetic wave sensor may be a device independently disposed at a preset height of the space, for example, it may be disposed at a desk or the like in the space, or it may be disposed in other devices having a preset height, for example, in a cabinet air conditioner or the like.
In some embodiments, the electromagnetic wave sensor may perform data acquisition of moving parts of the device. The electromagnetic wave sensor can send the collected data to air processing equipment, a cloud server and the like connected with the electromagnetic wave sensor, and the air processing equipment, the cloud server and the like are used for processing the data to generate the height information of the space. However, the present application is not limited thereto, and the corresponding data processing may be performed by an electromagnetic wave sensor.
According to the embodiment, the electromagnetic wave sensor is adopted to collect data of the moving parts in the space, and the space information of the space is generated according to the distance data and the angle data collected in the specified time, so that the problem of privacy leakage can be avoided, the cost for acquiring the space information can be reduced, and the accuracy of the space information can be improved.
