Background

When a video is shot, because a shot target (such as a person, an animal and the like) is often in a moving state, a focus created at the initial stage of video shooting is easily incapable of being focused with the target in time due to the movement of the target, and because the focus is not continuously focused in the whole process, the main body in the video is fuzzy, so that the quality of the shot video is low.

For example, when there is a blocking object (wall, etc.) between the camera and the object to be photographed, the camera loses focus when the object to be photographed is blocked by the blocking object, and the camera cannot determine and focus the object in time even after the object is separated from the blocking object; especially at night, when the light is not good, the target body cannot be focused accurately and continuously.

Detailed descriptions of known functions and known components are omitted in the present application in order to keep the following description of the embodiments of the present application clear and concise.

The embodiment of the application provides electronic equipment which can shoot videos and can ensure real-time focusing of a target object in the shooting process, and even if the target object is shielded by a shielding object, focusing of the target object can be achieved to a certain extent, and the purpose of improving the video quality is achieved.

Specifically, as shown in fig. 1, the electronic device provided in the embodiment of the present application includes a main body 1, and the main body 1 serves as a support or a carrier to carry various components of the electronic device, so as to ensure that the circuits of the electronic device can be normally connected.

Further, the electronic device further comprises a radar component 2, wherein the radar component 2 is arranged on the body 1. The radar component 2 corresponds to an induction area, and the induction area is an area where the radar component 2 can acquire radar data; further, the sensing area covers a first range, and the radar component 2 is used for collecting and processing radar data collected by the radar component 2 in the first range.

Here, the first range is a range determined by the obstacle, and at this time, even if the object is blocked by the blocking object, radar data corresponding to the object can be acquired through the radar component 2; of course, the first range may also be a range corresponding to the entire sensing area, and at this time, even if the object is blocked by the blocking object, the radar data corresponding to the object may be collected by the radar component 2.

Specifically, the radar assembly 2 includes a transmitter 21, a receiver 22, and a band microprocessor 23. The transmitter 21 is connected to a transmitting antenna, and in a specific implementation, the transmitter 21 modulates the millimeter-wave signal according to a preset rule, and transmits the millimeter-wave signal to the sensing area through the connected transmitting antenna. Then, the receiving antenna acquires the echo signal returned based on the millimeter wave signal in real time, where the receiver 22 is connected to the receiving antenna, and the receiving antenna transmits the acquired echo signal to the receiver 22. Thereby, the acquisition of radar data is accomplished by the transmitter 21, the transmitting antenna, the receiver 22 and the receiving antenna.

It is worth mentioning that the speed measurement is based on the frequency doppler effect principle of the radar unit 2 due to the relative motion between itself and the target. The frequency of the echo signal received by the radar component 2 is different from the frequency of the millimeter wave signal, the difference between the two is called doppler frequency, one of the main information extractable from the doppler frequency is the rate of change of the distance between the radar component 2 and the object, and even if the object and the interference clutter exist in the same spatial resolution unit of the radar component 2 at the same time, the radar component 2 can detect and track the object from the interference clutter by using the difference of the doppler frequency. Therefore, the embodiment of the present application preferably employs the radar component 2 to acquire radar parameters for the purpose of tracking an object and continuously focusing the object.

The transmitter 21 transmits the millimeter wave signal to the strip microprocessor 23 while transmitting the millimeter wave signal to the sensing region through the connected transmitting antenna, and likewise, the receiver 22 transmits the echo signal to the strip microprocessor 23 after receiving the echo signal. It should be noted that there are cases where millimeter wave signals are continuously transmitted, and therefore, the received echo signals need to establish a correspondence relationship with the millimeter wave signals to ensure accuracy of radar data, where the correspondence relationship may be set based on transmission time, transmission order, preset tags, and the like.

After receiving the millimeter wave signal and the echo signal corresponding to the millimeter wave signal, the band microprocessor 23 obtains the relative parameter of the object in the first range with respect to the electronic device based on the modulated millimeter wave signal and the echo signal, and in a specific implementation, the band microprocessor 23 may obtain the relative parameter by performing an analog-to-digital conversion operation, and of course, may also perform signal noise reduction and other processing as long as it can ensure that the relatively accurate relative parameter is obtained. Wherein, the relative parameters at least comprise at least one of the following parameters: the first range of objects is relative distance, relative velocity, heartbeat, and/or respiratory rate with respect to the electronic device. Here, the relative parameter is taken as a radar parameter.

The electronic device further comprises a camera assembly 3, and the camera assembly 3 is also arranged on the body 1. The camera component 3 corresponds to the acquisition area, the acquisition area covers the second range, the camera component 3 is used for acquiring and processing the acquisition data acquired by the camera component 3 in the second range, and similarly, the process of processing the acquisition data by the camera component 3 also involves analog-to-digital conversion, denoising and the like, which is not described herein in detail. Further, the first range in the embodiment of the present application covers the second range to determine that the radar component 2 can completely acquire radar data in the second range, so as to achieve subsequent focusing on the target object.

The electronic equipment provided by the embodiment of the application further comprises a processor 4, wherein the processor 4 is directly or indirectly connected with the radar component 2, so that radar data collected and processed by the radar component 2 can be acquired in real time; meanwhile, the processor 4 is also directly or indirectly connected with the camera component 3, so as to acquire the collected data collected and processed by the camera component 3 in real time. After the radar data and the collected data are acquired, the processor 4 calibrates the target object in the collected data after the radar data is processed.

Specifically, the processor 4 includes a first processing module 41, and after the radar data and the collected data are acquired, the first processing module 41 calibrates an object corresponding to a first range in the collected data based on a relative parameter, that is, the radar data. Specifically, the object in the second range may be determined according to a preset calibration rule, for example, an image corresponding to the first range is determined based on the collected data, and the image is identified, analyzed, and the like, so as to calibrate the object in the first range; then, the distance between the object and the camera assembly 3 is determined based on the acquired data and the camera assembly 3, and the position of the object in the first range is determined and calibrated based on the distance and the relative distance in the relative parameters. Of course, the calibration may also be performed based on the relative speed in the relative parameter, or may also be performed based on the relative distance and the relative speed, which is not specifically limited in this embodiment of the application. The object may be a person, an animal, a vehicle, or the like.

Further, the processor 4 further includes a second processing module 42, after completing calibration of the object in the first range, determining a living object based on the relative parameters of the object corresponding to the first range in the acquired data, specifically, checking whether the relative parameters corresponding to each calibrated object include a heartbeat and/or a respiratory frequency, or checking whether the heartbeat and/or the respiratory frequency is not 0, and if so, determining that the object is the living object. After the living object is determined, the display of the acquired data through the display screen and the display of a living mark of the living object, for example, the addition of a heart shape or the like on the living object, are controlled.

In a specific implementation, there is a case where only one object needs to be tracked within the first range, at this time, the second processing module 42 acquires a preset heartbeat and/or a breathing frequency pre-stored in the electronic device, compares the preset heartbeat and/or breathing frequency with the heartbeat and/or breathing frequency of each living object, determines that a living object corresponding to the same heartbeat and/or breathing frequency as the preset heartbeat and/or breathing frequency is a target object, differently sets a living mark of the target object to a living mark of another living object, for example, sets a living mark of another living object to be a heart shape, and sets a living mark of the target object to be a red heart shape.

The processor 4 further comprises a third processing module 43, the third processing module 43 predicts a focus position based on the relative parameter of the object corresponding to the first range in the acquired data, and controls the camera assembly 3 based on the focus position. Specifically, the third processing module 43 determines that the living body object corresponding to the heartbeat and/or respiratory rate identical to the preset heartbeat and/or respiratory rate is the target object, and then predicts the focusing position based on the relative speed of the target object.

In a specific implementation, there may also be a plurality of target objects having the same preset heartbeat and/or respiratory frequency, and at this time, the final target object may be further determined by the relative speed of each target object, that is, the preset speed stored in advance is compared with the relative speed of each target object, the target object corresponding to the same relative speed as the preset speed is determined as the final target object, and the focusing position is predicted based on the target object corresponding to the same relative speed as the preset speed.

Specifically, the movement locus of the target object within the first range, which is finally determined, is calculated, the focus position at each time is determined based on the movement locus and the relative speed of the target object, and the image pickup assembly 3 is controlled to perform focus shooting at the determined focus position.

The electronic equipment of the embodiment of the application utilizes the radar component 2 to collect and process radar data, and calibrates the target object based on the processed radar data through the processor 4, so as to ensure continuous focusing on the target object, avoid the situation that the target object is fuzzy due to discontinuous focusing, and improve the video quality.
