An embodiment of the present invention provides an image display method, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of an image display method according to the present invention.
In this embodiment, the image display method includes the steps of:
step S10: and when a meeting request instruction is received, determining a target image display mode according to the meeting request instruction, and acquiring current meeting participating target information.
It should be noted that the execution subject of the present embodiment may be an image display device, where the image display device may be a controller of a video conference device, for example: personal computer, control chip, etc., and may also be other device controllers capable of performing video conference, and this embodiment is not limited in particular.
It can be understood that the conference request instruction may be a request instruction for controlling the video conference device to start operating, which is input by a user through a button of the video conference device, a remote controller, or a mobile phone APP, and the conference request instruction may include a start signal of a conference initial mode.
It should be noted that, in this embodiment, the video conference device includes five modules: 1. a microphone array module; 2. a motor and a driving module; 3. a lens module; 4. a sensor module; 5. a controller; the microphone array module is used for collecting sound signals of a user during a video conference and sending the sound signals to the controller for detecting a sound direction, and in order to make the collected sound signals more complete and clear, the microphone array may be a multi-microphone array, for example: 4 wheat array, 6 wheat array, 8 wheat array, etc., and the embodiment is not limited in particular.
The motor and the driving module are used for rotating according to a signal sent by the controller, so that the lens can rotate and the adjustment of the position of the lens is realized.
In this embodiment, the lens in the lens module may be an image capturing lens capable of capturing an image at an angle of 220 °, or may be another lens capable of implementing the same or similar function; the sensor module is used for detecting the detection of the direction of the lens when the motor and the driving module control the lens to rotate so as to judge whether the rotation operation is finished.
It should be noted that the target image display mode may be a panoramic mode, a wide-angle mode, a private mode, and the like, and the video conference device controller may start the corresponding target image display mode according to a conference request instruction input by a user.
It can be understood that the current conference target information may be information such as the number of people currently participating in the conference, face information, and conference participation degree.
Step S20: and determining the orientation of the lens according to the target image display mode, and adjusting the orientation of the lens according to the orientation of the lens.
It should be noted that, the lens orientations corresponding to different target image display modes are different, in this embodiment, referring to fig. 3,1 shows a panoramic mode, and the lens orientation corresponding to the panoramic mode is that the lens faces upward; 2, a wide-angle mode, wherein the lens orientation of the wide-angle mode is that the lens faces forwards; and 3, a privacy mode, the privacy mode lens being oriented with the lens facing downward.
In a specific implementation, after the lens orientation is determined according to the target image display mode, the lens is controlled to rotate according to the motor and the driving module, so that the lens is rotated to the lens orientation corresponding to the target image display mode determined according to a conference request instruction input by a user.
Step S30: and determining a target image display strategy based on the lens position and the current meeting target information.
It should be noted that, in this embodiment, the image display policy may be a multi-person conversation image display policy, a moderator image display policy, a VIP image display policy, an alternate speech image display policy, and the like in the panoramic mode, or may also be a normal image display policy, and the like in the wide-angle mode, and in this embodiment, a specific target image display policy is determined according to the lens orientation and the current meeting target information.
It can be understood that, before determining the target image display strategy, the lens orientation is determined by the image display mode, so in this embodiment, according to three different target image display modes, the lens of the video conference device has three orientations, which are: lens up, lens forward, and lens down.
Step S40: and when the lens rotates to the lens direction, displaying a preset privacy image or a current target image acquired by the camera according to the target image display strategy.
It should be noted that the current target image may be a conference image acquired by a camera when the video conference device is in a panoramic mode or a wide-angle mode.
Further, in order to make the image collected by the camera more suitable for displaying, before step S40, the method further includes:
acquiring a current participating target image through a camera, and starting a microphone;
performing image segmentation on the current participating target image through a preset image segmentation model to obtain a segmented image;
and carrying out image processing on the segmented image to obtain a current target image.
It should be noted that the preset image segmentation model may be used to perform image segmentation on a target image acquired by a camera, extract a person image in the target image, and mark the person image as a segmented image.
It can be understood that the current target image is an expanded view obtained after the target image is expanded according to the target image acquired by the camera, and in the process of expanding, an expansion point needs to be determined first, in this embodiment, the determination of the position of the expansion point may be by determining a segmentation initial point of the current participant target image based on the lens position; and performing image segmentation on the current participating target image through a preset image segmentation model based on the segmentation initial point and a preset direction to obtain a segmented image.
In specific implementation, in the process of segmenting the current meeting target image collected by the camera, the current meeting target image needs to be detected according to a preset human face detection model and a human shape detection model, and incomplete target images caused by cutting complete people into half are avoided.
In addition, after the target image display strategy shows the current target image acquired by the preset privacy image or the camera, the participant who speaks when the video conference is carried out can be marked, so that the user can know who speaks more intuitively, and better experience can be realized.
Further, after step S40, the method further includes:
carrying out mouth shape detection on the current target image through a preset mouth shape detection model to obtain an initial speaker image;
acquiring a current sound signal through a microphone, and determining speaker information according to the current sound signal;
and determining a target speaker image according to the speaker information and the initial speaker image, and marking the target speaker image.
It should be noted that the preset mouth detection model is used for detecting the mouth movement of the participant target in the current participant target image, when the participant target speaks, the mouth moves, so as to determine the participant target speaking, and meanwhile, since the possible participant target does not send a sound signal, but detects the mouth movement, the initial speaker information can be obtained through the preset mouth detection model.
It can be understood that the sound signal obtained by the microphone is subjected to direction prediction through a preset direction prediction model and initial speaker information, so that an accurate target speaker can be determined, and the target speaker image is marked.
It should be noted that the marking of the target speaker may be to increase the brightness of the target speaker image in the display image, mark different colors, or the like, or may be other marking methods with the same or similar marking functions, and this embodiment is not limited in particular.
In the embodiment, when a meeting request instruction is received, a target image display mode is determined according to the meeting request instruction, current meeting-participating target information is acquired, a lens orientation is determined according to the target image display mode, the lens orientation is adjusted according to the lens orientation, a target image display strategy is determined based on the lens orientation and the current meeting-participating target information, and when the lens orientation is rotated to the lens orientation, a preset privacy image or a current target image acquired by a camera is displayed according to the target image display strategy. The embodiment determines the target image display mode through a conference request instruction input by a user, adjusts different lens positions according to different target image display modes, is suitable for image display in multiple scenes, selects a proper target image display strategy according to the combination of the lens positions and current conference participating target information, and possibly selects different image display modes according to the difference of the conference participating target information, thereby avoiding the technical problems that the video session can only be used in a single application scene, the conference mode can not select different display modes according to the number of participants, and the user experience is poor.
Referring to fig. 4, fig. 4 is a flowchart illustrating an image display method according to a second embodiment of the present invention.
Based on the foregoing first embodiment, in this embodiment, the step S30 includes:
step S301: and if the lens position is that the lens faces upwards, acquiring the number of the conference targets and the conference participation degree in the current conference target information.
It should be noted that the conference participation degree may be obtained by calculating the total number of the sound signals collected by the microphone array of the video conference device and the sources of the sound signals, and when the conference participation degree is obtained by processing the sound signals, the total number of the sound signals may be larger, the conference participation degree may be higher, the number of the sources of the sound signals may be larger, and the conference participation degree may be higher.
Step S302: and determining a target image panoramic display strategy according to the lens position, the number of the conference participating targets and the conference participation degree.
It should be noted that, when the lens is facing upward, the target image panoramic display strategy includes four target image display strategies: 1. a VIP image display strategy; 2. a host image display policy; 3. a multi-person conversation image display policy; 4. an alternate-talk image display strategy; and selecting a proper target image display strategy according to the specific number of the conference targets and the conference participation degree.
Further, since the number of conference targets is different and the conference participation degree is different, when the image display policy is selected, it is necessary to select a different image display policy, that is, step S301 includes:
when the lens position is that the lens faces upwards, acquiring the number of conference participating targets and the conference participation degree in the current conference participating target information;
judging whether host information exists in the current participating target information;
if the conference participation degree exists, comparing the conference participation degree with a first preset value, and comparing the conference participation target number with a second preset value;
when the conference participation degree exceeds a first preset value and the number of the conference targets is greater than a second preset value, determining a VIP image display strategy according to the conference request instruction, the number of the conference targets and the conference participation degree;
when the conference participation degree does not exceed a first preset value and the number of the conference targets is smaller than a second preset value, determining a host image display strategy according to the conference request instruction, the number of the conference targets and the conference participation degree;
it can be understood that the host information can be a participating target image which needs to be displayed for a long time, the host information can be a conference host, an organizer or a person needing to be fixedly displayed, the person right in front of the video conference equipment can also be used as a default host, in actual operation, the host information can be manually switched to the host by adjusting the placement of the video conference equipment, the host can also be switched through keys, a remote controller, a mobile phone APP and the like on the video conference equipment, and the embodiment is not particularly limited.
Secondly, when host information exists, different image display strategies are selected according to the conference participation degree and the number of participants, and in actual operation, when the conference participation degree exceeds a first preset value and the number of the participants is greater than a second preset value, the target image display strategy is a VIP image display strategy; when the conference participation degree does not exceed a first preset value, and when the number of the conference participating targets is smaller than a second preset value, the target image display policy is a moderator image display policy, where the first preset value and the second preset value may be values preset by a user, and this embodiment is not particularly limited.
It should be noted that in the VIP image display policy, one VIP location is set, and generally the VIP location is fixed at the upper left corner, and the other number and location may not be fixed, in this embodiment, the number of non-VIP locations is 5, and when a person is detected to speak, the target image corresponding to the speaking participant is extracted to the other locations by detection, and the target image is located in five frames of the non-VIP location clockwise with the VIP location as the starting point.
It should be understood that in the moderator image display strategy, all the acquired participant target images are integrated to obtain a panoramic image containing all the participant target images, the panoramic image is fixed at the lower end of the display image, and the moderator image is fixed at the upper end, so that a plurality of moderator information conditions may occur, and therefore, a plurality of moderator images can be placed at the upper end of the display image.
In addition, if the conference participation degree and the number of participants change in the video conference process, the change can be detected through a preset human shape detection model and a preset human face detection model, and the target image display strategy is changed according to different conference participation degrees and different numbers of participants.
In specific implementation, after the video conference equipment detects information of a host, the existing six people a, B, C, D, E and F confirm that a is the host, and when the conference participation degree exceeds a first preset value and the number of the conference participating targets is greater than a second preset value, the target image display strategy is a VIP image display strategy, so that the six people are shown in fig. 5 at video image display positions.
If the A is the host and the conference participation degree does not exceed the first preset value, and the number of the participating targets is smaller than the second preset value, the target image display strategy is the host image display strategy, and therefore the video image display positions of six people are shown in fig. 6.
Further, during the video conference, there is a possibility that there is no host, so step S302 further includes:
if not, comparing the number of the participating targets with a second preset value;
when the number of the conference participating targets does not exceed a second preset value, determining a multi-person conversation image display strategy according to the conference request instruction, the number of the conference participating targets and the conference participation degree;
and when the number of the conference participating targets exceeds a second preset value, determining an alternate speaking image display strategy according to the conference request instruction, the number of the conference participating targets and the conference participation degree.
It should be noted that, in the multi-person conversation image display strategy, the acquired meeting target images are integrated to obtain a panorama including all the meeting target images, the panorama is fixed at the lower end of the display image, three image frames are fixed at the upper end of the display image, when the meeting target is detected to speak, the display target image is adjusted, if the number of the meeting target in the panorama is not enough for three people, only the image frame corresponding to the number of people is displayed at the upper end of the display image, and a black frame is displayed when the number of people is not enough, in addition, the sequence of the three image frames is fixed, for example: at present, there are six people a, B, C, D, E, F, and which image frame display sequence at the upper end of the display image is: ABC, ABD, ABE, ABF, ACD, ACE, ACF, ADE, ADF, AEF in 10 sequences.
It should be understood that, in the alternative utterance image display strategy, there may not be a fixed number of image frames, and the display image may be cut according to the number of conference participating targets, where the cutting rule is:
when only 1 person exists, the picture for displaying the image only has one photo frame;
when only 2 persons exist, the picture for displaying the image is equally divided left and right, and 2 persons are displayed;
when only 3 people exist, the picture of the display image is divided into 4 parts according to the upper part, the lower part and the left part, 3 people are displayed, but the picture at the lower right corner is displayed by adopting a black screen;
when only 4 people exist, dividing the picture of the display image into 4 parts according to the upper part, the lower part, the left part and the right part, and displaying 4 people;
when only 5 people exist, dividing the picture into 6 parts as shown in figure 12, displaying 5 people, but displaying the picture at the lower right corner by adopting a black screen;
when there are only 6 persons, 6 are displayed as an equal division of 6 in fig. 12;
when only 7 people exist, the picture of the display image is divided into 9 parts according to the upper part, the lower part and the left part, 7 people are displayed, but 2 pictures at the lower right corner are displayed by adopting a black screen;
when only 8 people exist, the picture of the displayed image is divided into 9 parts according to the upper part, the lower part and the left part, 8 people are displayed, but the picture at the lower right corner is displayed by adopting a black screen;
when only 9 people exist, the picture of the display image is divided into 9 parts according to the upper part, the lower part, the left part and the right part, and 9 people are displayed;
when the number of people is more than 9, the picture display is only 9, the initially displayed people are respectively displayed clockwise according to the first speaking person, and when the 10 th person speaks, the last speaking person is replaced;
it can be understood that when the video conference equipment does not detect the information of the host, the number relation between the number of the participating targets and the second preset value is judged, and when the number of the participating targets does not exceed the second preset value, the target image display strategy is a multi-person conversation image display strategy; and when the number of the participating targets exceeds a second preset value, the target image display strategy is an alternate speaking image display strategy.
In a specific implementation, when the number of the participating targets does not exceed the second preset value, the target image display strategy is a multi-person conversation image display strategy, and the display image is as shown in fig. 7 for the existing six persons a, B, C, D, E, and F.
When the number of the participating targets exceeds a second preset value, the target image display strategy is an alternate speech image display strategy, and the display image according to the cutting rule is shown in fig. 8.
In the embodiment, when a meeting request instruction is received, a target image display mode is determined according to the meeting request instruction, current meeting-participating target information is obtained, a lens position is determined according to the target image display mode, the lens orientation is adjusted according to the lens position, if the lens position is that a lens faces upwards, the number of meeting-participating targets and the meeting participation degree in the current meeting-participating target information are obtained, a target image panoramic display strategy is determined according to the lens position, the number of meeting-participating targets and the meeting participation degree, and when the lens orientation rotates to the lens position, a preset privacy image or a current target image obtained by a camera is displayed according to the target image display strategy. The embodiment determines the target image display mode through a conference request instruction input by a user, adjusts different lens orientations according to different target image display modes, is suitable for image display in multiple scenes, selects a proper target image panoramic display strategy according to the combination of the lens orientations, the number of conference participating targets and the conference participation degree, and possibly selects different image display modes according to the difference of conference participating target information, thereby avoiding the technical problems that the video session can only be used in a single application scene, different display modes cannot be selected according to the number of the conference participating persons, and the user experience is poor.
Referring to fig. 9, fig. 9 is a flowchart illustrating an image display method according to a third embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
and S301A, if the lens position is that the lens faces forwards, determining a wide-angle display strategy of the target image according to the lens position and the current meeting information.
It can be understood that if the target display mode is the wide-angle mode, that is, the lens position is the lens forward, and if the lens position is the lens forward, the target image wide-angle display strategy is determined according to the lens position and the current conference participation information.
It should be noted that, in this embodiment, since the lens of the video conference device is capable of capturing an image in a wide angle range of 220 ° when the lens is facing forward, the larger the angles on both sides of the lens, the larger the distortion of the image, and in order to have a good image display effect, the angles on both sides of the obtained 220 ° picture can be cut off by 20 °, so as to achieve an effect of 180 ° image.
In a specific implementation, referring to fig. 10, four people a, B, C, and D are located in front of the video conference device, at this time, the camera acquires images of the four people, but since the positions of the two people B and C relative to the two people a and D are far from the lens, the portrait of the picture B and C displayed on the monitor is larger than that of the people a and D, so as to distinguish the distance relationship between the conference object and the video conference device, and finally show an image as reference fig. 11.
If three BCD people leave and only remain A and sit at the original position, the portrait of the A is correspondingly amplified and placed in the middle; when the ACD three persons leave and only remain B to sit at the original position, the position of the B is close to the side, so that the whole person B is preferentially kept in the display frame during amplification, and finally the position of the B is amplified to a certain extent and deviates to the left; when only two AD people exist on the whole conference table, the AD images are amplified in the same proportion and placed in the middle because the distances between the two AD people and the video conference equipment are the same; when only two BC persons exist on the whole conference table, the portrait is amplified in the same proportion after the B and the C are detected, but the amplification proportion of BC is smaller than AD because the two BC persons sit close to each other; when only two people including BD are on the whole conference table, the human figure and other scenes in the picture are amplified in the same proportion after B and D are detected, and because B is closer to the lens and is closer to the side, the position of B is detected simultaneously during amplification in the same proportion, and the body of B is prevented from exceeding the display picture.
