Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the present disclosure, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions, and the terms "comprise," "include," or any other variation thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The application is operational with numerous general purpose or special purpose computing device environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet devices, multiprocessor devices, distributed computing environments that include any of the above devices or devices, and the like.
The embodiment of the application provides a data processing method which can be independently applied to a TOF sensor or can be applied to various electronic devices provided with the TOF sensor, namely, an execution main body of the data processing can be the TOF sensor or the electronic device provided with the TOF sensor. The flow chart of the data processing method is shown in fig. 1, and specifically includes:
s101: and obtaining an induction signal.
In this embodiment, the sensing signal is obtained first.
In one embodiment, if the execution body is a separate TOF sensor, the sensing signal is a return signal received by the separate TOF sensor after sending out a detection signal, it will be understood that if the detection signal sent by the separate TOF sensor is a laser signal, the obtained sensing signal is also a laser signal, and if the detection signal sent by the separate TOF sensor is an ultrasonic signal, the obtained sensing signal is also an ultrasonic signal, and the type of the TOF sensor is not limited in this embodiment. When the detection signal is an ultrasonic signal, a plurality of continuous periods of sensing signals can be combined to determine the gesture of the user, for example, in a first-aid scene, the equipment is far away from the user, but the ultrasonic signal can be sent to judge whether the user sends a distress gesture or not so as to alarm.
In another embodiment, if the execution body is an electronic device provided with a TOF sensor, the sensing signal is corresponding depth information calculated by the TOF sensor in the electronic device after sending a detection signal and receiving a return signal, and the TOF sensor outputs the depth information to a processor of the electronic device, and the processor obtains the sensing signal to obtain the corresponding depth information output by the TOF sensor.
It should be noted that, the sensing signal obtained in this step is a return signal corresponding to the same detection signal, and a longer detection period may be set before transmission, so as to ensure that the return signal corresponding to one detection signal must be corresponding in one detection period.
S102: and if in the first mode, responding based on the sensing signal and a first processing mechanism.
In this embodiment, after the sensing signal is obtained, different processing mechanisms are further adopted according to different modes, and at least two modes exist: a first mode and a second mode, the first mode and the second mode belonging to different modes. It will be appreciated that the first mode may be a mode of a separate TOF sensor or a mode of an electronic device provided with a TOF sensor.
Specifically, if in the first mode, a response is based on the sense signal and a first processing mechanism.
In one embodiment, if the executing body is a separate TOF sensor, the first mode is a mode of the separate TOF sensor. In the first mode, if the separate TOF sensor obtains one sensing signal, the separate TOF sensor outputs one depth information or does not output the depth information, and if the separate TOF sensor obtains at least two sensing signals, the separate TOF sensor still outputs one depth information or does not output the depth information. In the second case, the TOF sensor screens out one of the at least two sensing signals as a return signal corresponding to the detection signal, so as to be used as a basis for calculating depth information, and the other sensing signals are discarded as noise. That is, in the first mode, the individual TOF sensor outputs at most only one depth information, regardless of the acquisition of several sensing signals. This is the response of the separate TOF sensor based on the sensing signal and the first processing mechanism in the first mode. In summary, there are two forms of response based on the sensing signal and the first processing mechanism, one is that the TOF sensor outputs one depth information or does not output when one sensing signal is obtained, and the other is that the TOF sensor still outputs one depth information or does not output when at least two sensing signals are obtained.
In another embodiment, if the execution body is an electronic device provided with a TOF sensor, the mode is a mode of the electronic device, if the mode is a mode of the electronic device, the processor of the electronic device selects a corresponding processing mechanism according to the mode in which the electronic device is located, and specifically if the electronic device is in the first mode, the processor of the electronic device responds based on the sensing signal and the first processing mechanism. It should be noted that if the execution body is an electronic device provided with a TOF sensor, the modes of the electronic device may be two cases, one considers only the physical mode of the electronic device, and one considers both the physical mode of the electronic device and the mode of the TOF sensor on the electronic device, and the different cases correspond to different modes.
S103: responding, if in a second mode, based on the sense signal and a second processing mechanism; the sensing signals corresponding to the second mode are determined based on at least two different sensing signals aiming at the same detection signal; wherein the first mode is different from the second mode.
In this embodiment, the first processing mechanism corresponds to a first mode, and the second processing mechanism corresponds to a second mode, and similarly, the second mode may be a mode of a separate TOF sensor or a mode of an electronic device provided with a TOF sensor.
Specifically, if in the second mode, a response is based on the sense signal and a second processing mechanism.
In one embodiment, if the executing body is a separate TOF sensor, the second mode is a mode of a separate TOF sensor. In the second mode, if the separate TOF sensor obtains at least two sensing signals, the separate TOF sensor outputs at least two depth information at which time the sensing signals corresponding to the second mode are determined based on at least two different sensing signals for the same detection signal. That is, in the second mode, the separate TOF sensor obtains several sensing signals, which output several depth information. This is the response of the separate TOF sensor based on the sensing signal and a second processing mechanism in the second mode.
In another embodiment, if the execution body is an electronic device provided with a TOF sensor, the second mode is a mode of the electronic device. If the electronic device is in the second mode, the processor of the electronic device will respond based on the sensed signal and the second processing mechanism.
It can be seen that, in the embodiment of the present application, the sensing signal is obtained first, if in the first mode, based on the sensing signal and the first processing mechanism response, and if in the second mode, based on the sensing signal and the second processing mechanism response; the sensing signals corresponding to the second mode are determined based on at least two different sensing signals aiming at the same detection signal; wherein the first mode is different from the second mode. Aiming at the TOF sensor or the device carrying the TOF sensor, through the steps, the TOF sensor and the device carrying the TOF sensor can have various optional processing mechanisms, different processing mechanisms are triggered under different modes to realize functional response, and the defects of limited functions, reduced user experience and the like caused by adopting a single processing mechanism under any condition are avoided.
In this embodiment, at least two different sensing signals for the same detection signal characterize the target optical signal as having a second medium on a propagation path formed in the first medium by the target object. That is, the detection signal passes through the second medium before reaching the target object, the second medium is located between the target object and the emission source for emitting the detection signal, the second medium may be an object mainly reflecting or an object mainly transmitting, if the object mainly reflecting, the second medium may be a mirror or the like, and the reflection of the mirror is utilized to make the same detection signal have at least two different sensing signals; if the transmission is the main, the second medium may be glass or the like, and the transmission of the glass is used to make the same detection signal have at least two different sensing signals.
The embodiment of the application provides a specific data processing method, an execution main body is an electronic device provided with a TOF sensor, a flow chart of the method of the data processing method is shown in fig. 2, and the method specifically comprises the following steps:
s201: the target optical signal is emitted.
S202: a first induced signal is obtained, the first induced signal being the target optical signal for a first return of the target optical signal.
S203: a second induced signal is obtained, the second induced signal being the target optical signal for a second return of the target optical signal.
S204: and determining a sensing signal based on the first sensing signal and the target optical signal, wherein the sensing signal is used for representing a first distance.
S205: and determining a sensing signal based on the second sensing signal and the target optical signal, wherein the sensing signal is used for representing a second distance, and the sensing signal comprises a first distance and a second distance.
In this embodiment, the detection signal is a laser detection signal, and the TOF sensor in the electronic device first emits a target optical signal, and for the target optical signal, the TOF sensor obtains two sensing signals, where the two sensing signals belong to two different moments of the same acquisition period for the target optical signal. Specifically, a first sensing signal is obtained first, wherein the first sensing signal is the target optical signal returned for the first time of the target optical signal, and then a second sensing signal is obtained, and the second sensing signal is the target optical signal returned for the second time of the target optical signal. The energy of the target optical signal represented by the first sensing signal is different from the energy of the target optical signal represented by the second sensing signal, and the obtaining of the first sensing signal and the obtaining of the second sensing signal belong to two different moments of the same acquisition period for the target optical signal. It will be appreciated that the energy of the target optical signal characterized by the first sensing signal must be different from the energy of the target optical signal characterized by the second sensing signal, as the energy of the same detection signal must be different before and after reflection or before and after transmission.
The sensing signal is used to determine a distance (i.e. depth information) and thus, when the first sensing signal is obtained, a sensing signal is determined based on the first sensing signal and the target light signal, where the sensing signal is used to characterize the first distance. And determining a sensing signal based on the second sensing signal and the target optical signal when the second sensing signal is obtained, wherein the sensing signal is used for representing a second distance. At this time, the TOF sensor generates two distance information (the first distance and the second distance), that is, the sensing signal finally generated by the TOF sensor includes the first distance and the second distance, but the TOF sensor may not necessarily output all the signals, and the processor of the subsequent electronic device may select different processing mechanisms according to the output situation of the TOF sensor.
It is understood that the first distance reflects the distance between the second medium and the TOF sensor and the second distance reflects the distance between the target object and the TOF sensor.
S206: if the sense signal includes a single set of distance values, a target instruction is determined based on the sense signal and a first threshold range.
S207: if the sense signal includes two sets of distance values, a target instruction is determined based on the sense signal and a second threshold range, the second threshold range being the same as the first threshold range.
In this embodiment, if the sense signal includes a single set of distance values, a target instruction is determined based on the sense signal and a first threshold range. Specifically, if the sensing signal output by the TOF sensor has only one set of distance values, which indicates that the TOF sensor is in the first mode, the TOF sensor selects one set of the first distance and the second distance to output in the first mode, and the processor obtains one set of the first distance and the second distance, at this time, the processor determines the target instruction based on the sensing signal and the first threshold range, that is, determines the target instruction based on the set of distance values and the first threshold range. When determining a target instruction based on the sensing signal and the first threshold range, a single set of distance values is compared with the first threshold range.
In this embodiment, if the sensing signal includes two sets of distance values, the target instruction is determined based on the sensing signal and the second threshold range. Specifically, if the sensing signal output by the TOF sensor has two sets of distance values, which indicates that the TOF sensor is in the second mode, and indicates that the TOF sensor outputs the first distance and the second distance in the second mode, the processor obtains the first distance and the second distance, and at this time, the processor determines the target instruction based on the sensing signal and the second threshold range, that is, determines the target instruction based on the two sets of distance values and the second threshold range at the same time. When the target instruction is determined based on the sensing signal and the second threshold range, the difference value of the two sets of distance values is mainly compared with the second threshold range, and the difference value of the two sets of distance values reflects the distance between the target object and the screen. On this basis, the second threshold range is identical to the first threshold range.
That is, in this embodiment, the threshold range for determining the target instruction is unchanged regardless of the mode in which the TOF sensor is in. The following describes a specific scenario as an example, where the scenario is an automatic screen locking scenario, the target instruction is used for screen locking control, the first threshold range and the second threshold range are distance ranges between the target object (user) and the screen, and when the target object is located in the distance range, screen locking is not performed, and when the target object is located outside the distance range, screen locking is performed. At this time, if the sensing signal includes a single set of distance values, a target instruction for performing screen locking control is determined based on the sensing signal and a first threshold range, and if the sensing signal includes two sets of distance values, a target instruction for performing screen locking control is determined based on the two sets of distance values and a second threshold range, the second threshold range being the same as the first threshold range. When the TOF sensor is in the first mode and outputs a single set of distance values, if the single set of distance values is within 50cm, the user is not locked in front of the screen. When the TOF sensor is in the second mode outputting two sets of distance values, if the difference between the two sets of distance values is within 50cm, it is indicated that the user is not performing screen locking in front of the screen.
It can be understood that for the automatic screen locking function, the screen locking distance can be set to different gear positions, such as a Near gear, a Middle gear and a Far gear Far, where the different gear positions indicate that the distance of the user in front of the screen is different, and the threshold ranges corresponding to the different gear positions are different, which is not limited in this embodiment.
In this embodiment, on the basis of steps S201 to S205, there are two schemes in parallel with step S206, scheme 1: and if the attribute of the sensing signal characterizes the sensing signal to be determined based on the primary sensing signal of the optical signal, determining a target instruction based on the sensing signal and a first threshold range. Scheme 2: determining a target induction signal by using the induction signal to represent that the energy of the target optical signal is larger than an energy threshold value; and determining a sensing signal based on the target sensing signal and the target optical signal, wherein the sensing signal is used for representing the distance.
In this embodiment, on the basis of steps S201 to S205, there are two schemes in parallel with step S207, scheme 1: and if the attribute of the sensing signal characterizes the sensing signal is determined based on the twice sensing signals of the optical signal, determining a target instruction based on the sensing signal and a second threshold range, wherein the second threshold range comprises the first threshold range. Scheme 2: determining an induced signal based on the first induced signal and the target optical signal, the induced signal being used to characterize a first distance; and determining a sensing signal based on the second sensing signal and the target optical signal, wherein the sensing signal is used for representing a second distance, and the sensing signal comprises a first distance and a second distance.
The embodiment of the application provides a specific data processing method, an execution main body is an electronic device provided with a TOF sensor, a flow chart of the method of the data processing method is shown in fig. 3, and the method specifically comprises the following steps:
s301: the target optical signal is emitted.
S302: a first induced signal is obtained, the first induced signal being the target optical signal for a first return of the target optical signal.
S303: a second induced signal is obtained, the second induced signal being the target optical signal for a second return of the target optical signal.
S304: and determining the target induction signal by using the energy of the target optical signal, which is characterized by the induction signal, to be larger than an energy threshold value.
S305: and determining a sensing signal based on the target sensing signal and the target optical signal, wherein the sensing signal is used for representing the distance.
In this embodiment, the detection signal is a laser detection signal, and the TOF sensor in the electronic device first emits a target optical signal, and for the target optical signal, the TOF sensor obtains two sensing signals, where the two sensing signals belong to two different moments of the same acquisition period for the target optical signal. Specifically, a first sensing signal is obtained first, wherein the first sensing signal is the target optical signal returned for the first time of the target optical signal, and then a second sensing signal is obtained, and the second sensing signal is the target optical signal returned for the second time of the target optical signal. The obtaining the first sensing signal and the obtaining the second sensing signal belong to two different moments of the same acquisition period for the target optical signal. It will be appreciated that the energy of the target optical signal characterized by the first sensing signal must be different from the energy of the target optical signal characterized by the second sensing signal, as the energy of the same detection signal before and after reflection or transmission must be different.
Likewise, the first distance reflects a distance between the second medium and the TOF sensor, and the second distance reflects a distance between the target object and the TOF sensor. Unlike the previous embodiment, in this embodiment, the TOF sensor does not output all or randomly select a set of distance values after obtaining the first sensing signal and the second sensing signal, but determines the target sensing signal by using the sensing signal that the energy of the target optical signal is greater than the energy threshold, that is, the TOF sensor outputs a distance value with large energy in the two sets of distance values, where the distance value with large energy reflects the distance between the target object and the TOF sensor.
S306: a target instruction is determined based on the sense signal and a first threshold range.
S307: a target instruction is determined based on the sense signal and a second threshold range, the second threshold range including the first threshold range.
In this embodiment, the TOF sensor is in a first mode and only outputs a distance value related to the position of the target object, if the electronic device is in the first mode at this time, the processor of the electronic device determines the target instruction based on the sensing signal and a first threshold range, and if the electronic device is in a second mode at this time, the processor of the electronic device determines the target instruction based on the sensing signal and a second threshold range, which in this embodiment includes the first threshold range, that is, the second threshold range must be larger than the first threshold range, unlike the previous embodiment.
It should be noted that the first mode and the second mode of the TOF sensor are virtual modes, the first mode of the TOF sensor means that the TOF sensor does not output or only outputs one distance value characterized by one sensing signal, and the second mode of the TOF sensor means that the TOF sensor outputs two distance values characterized by two sensing signals. The first mode and the second mode of the electronic device are physical modes of the device, the first mode of the electronic device meaning that the electronic device is in a first device pose and the second mode of the electronic device meaning that the electronic device is in a second device pose.
Still taking an automatic screen locking scene as an example, when the electronic device is in the first mode, the screen locking distance is assumed to be set to be 50cm, and if the distance output by the TOF sensor is within 50cm, the user is not locked in front of the screen. When the electronic device is in the second mode, the screen locking distance is set to be larger than that of the first mode, for example, 70cm, and if the distance output by the TOF sensor is within 70cm, the user is not locked in front of the screen.
In this embodiment, on the basis of steps S301-305, there is a scheme in parallel with step S306: determining a target induction signal by using the induction signal to represent that the energy of the target optical signal is larger than an energy threshold value; and determining a sensing signal based on the target sensing signal and the target optical signal, wherein the sensing signal is used for representing the distance. There is also a scheme in parallel with step S307: determining an induced signal based on the first induced signal and the target optical signal, the induced signal being used to characterize a first distance; and determining a sensing signal based on the second sensing signal and the target optical signal, wherein the sensing signal is used for representing a second distance, and the sensing signal comprises a first distance and a second distance.
The embodiment of the application provides a specific data processing method, an execution main body is an electronic device provided with a TOF sensor, a flow chart of the method for processing the data is shown in fig. 4, and the method specifically comprises the following steps:
s401: the sensing signal and the target parameter are obtained.
In this embodiment, a TOF sensor in the electronic device collects sensing signals, and a TOF sensor or other components in the electronic device collect target parameters, where the target parameters are parameters that can reflect a device posture of the electronic device, for example, a gravity sensor in the electronic device may collect relevant gravity parameters to determine the device posture of the electronic device.
S402: and if the target parameter meets a first condition, representing that the electronic equipment is in a first equipment posture, controlling the electronic equipment to be in the first mode, and responding based on the sensing signal and a first processing mechanism.
S403: and if the target parameter meets a second condition, representing that the electronic equipment is in a second equipment gesture, controlling the electronic equipment to be in the second mode, and responding based on the sensing signal and a second processing mechanism.
In this embodiment, if the target parameter satisfies a first condition, the electronic device is represented as being in a first device posture, and the electronic device is controlled to be in the first mode, based on the sensing signal and a first processing mechanism response. And if the target parameter meets a second condition, representing that the electronic equipment is in a second equipment gesture, controlling the electronic equipment to be in the second mode, and responding based on the sensing signal and a second processing mechanism. As described above, the first mode and the second mode of the electronic device are physical modes of the device, the first mode of the electronic device meaning that the electronic device is in a first device pose and the second mode of the electronic device meaning that the electronic device is in a second device pose.
In this embodiment, if the electronic device is in the second device posture, the light emitting angle of the light emitting unit of the detecting device may be adjusted so that the electronic device is in the second device posture, and it is easy to understand that the target light signal emitted by the detecting device is located in the target body of the electronic device when the electronic device is in the second device posture. The detection device is a TOF sensor, and the target light signal emitted by the light emitting unit of the TOF sensor can reach the body of the electronic equipment under the gesture of the second equipment. It should be noted that, in the second device posture, since there is reflection on the target body, if the energy of the target optical signal emitted by the light emitting unit of the TOF sensor is the same as the energy of the target optical signal emitted by the light emitting unit of the TOF sensor when there is no reflection at this time, the second sensing signal may not be returned due to the reflection energy loss, and in order to avoid this problem, the energy of the target optical signal emitted by the light emitting unit of the TOF sensor in the second device posture may be enhanced appropriately.
Fig. 5 is a schematic diagram of the dual-screen notebook in the second device posture, where the target body is another screen. In this case, the data processing method of the present embodiment has a strong correlation with the structural design of the electronic device, and the electronic device further includes a first body and a second body. The first body comprises a first screen positioned on the first surface of the first body, the detection device is positioned in the first body, and a target light signal emitted by a light emitting unit of the detection device passes through the first surface; the returned detection signal received by the receiving unit of the detection device passes through the first indication. The first body is connected with the two bodies in a turnover way and comprises a second screen positioned on the second surface of the second body. On the basis, the processor is used for controlling the electronic equipment to be in the second mode if the target parameter meets a second condition to represent the electronic equipment to be in a second equipment posture, wherein the second equipment posture is that the first body and the second body are at a target angle, and the target light signal emitted by the detection device is located in the second screen.
Of course, besides the dual-screen notebook, the single-screen notebook, the mobile phone, the PAD and other devices can also have the second device gesture, for example, if the electronic device is the single-screen notebook, the target body is an output operation interface, and a device capable of reflecting light needs to be arranged on the output operation interface, so that the target light signal emitted by the detection device is located in the target body of the electronic device.
In this embodiment, if the target parameter characterizes that the electronic device is in the second device posture, a target distance is further required to be obtained based on a light emitting angle of the detection device and a deployment angle of the electronic device when the electronic device is in the second device posture, where the target distance characterizes a distance from a target light signal emitted by the detection device to a target body of the electronic device when the electronic device is in the second device posture. The target distance, that is, the first distance in the foregoing embodiment, may be calculated by a light emission angle of the TOF sensor and an unfolding angle (machine opening/closing angle) of the electronic device when the TOF sensor cannot output the distance value.
As shown in fig. 6, the unfolding angle of the electronic device is θ, a is a point (first emission point) indicated by the target sensor, la is a target optical signal of the TOF sensor, b is a point corresponding to the point a and emitted to the C-plane screen, and the actual calculation manner of the target distance La is as follows: the point a is a vertical auxiliary line L1 relative to the rotating shaft and generates an intersection point, and the intersection point is a vertical auxiliary line L2 on the C plane, so that the point of the L2 on the C plane is respectively connected with the auxiliary lines L3 and L4 obtained after the point a and the point b are mutually vertical. From this, it can be known that the triangle formed by L1, L2, L3, the included angle between L1 and L2 is θ, for this triangle, two sides and the included angle thereof are known, L3 can be obtained:
Triangles composed of L3, L4, la are right triangles, so La is:
on this basis, if in the first mode, the response based on the sense signal and the first processing mechanism comprises: a target instruction is determined based on the sense signal and a first threshold range. If in the second mode, responding based on the sense signal and a second processing mechanism includes: a target instruction is determined based on the sensed signal, the target distance, and a second threshold range, the second threshold range being the same as the first threshold range.
Further, in the case shown in fig. 5, the mode of the electronic device is not switched to the second mode at any time, and the mode of the electronic device is switched to the second mode only when the electronic device is in the second device posture and the target object to be detected is located at the target detection edge. The electronic device shown in fig. 7 is in the second device posture but the target object is not located at the target detection edge, and the second mode is not switched at this time, and the electronic device shown in fig. 8 is in the second device posture and the target object is located at the target detection edge, and the second mode is switched at this time, and the target detection edge or a place located beyond the edge needs to be detected by using the reflected target light signal.
In this embodiment, assuming that the target object is not located at the detection edge at first and moves to the detection edge during use, it is determined whether the target object is switched to the detection edge or not by the moving direction of the target object. Specifically, the moving direction of the target object can be judged by the bitmap information output by the TOF sensor, and the moving direction of the target object is determined according to the change of the bitmap information:
D b ＝{D L1 ,…,D L2 }∈D
wherein D is the bitmap information corresponding to the target area, and Db is the bitmap information corresponding to the covered part of the target object in the target area.
According to the depth change rate of the lattice information, a new region D 'can be obtained, and according to the position relation between D' and Db, the parameters for determining the movement of the target object are as follows:
as shown in fig. 9, the moving direction corresponding to fig. 9 is moving leftwards, and since the TOF sensor is disposed on the left screen, if the depth information of the parameter indicating the target object gradually becomes smaller until the depth information of the target object cannot be detected in the target area, the indicating target object moves leftwards from the target area until the target detection edge.
