In the above step S502, the refrigerator 10 may start the configuration mode when receiving a configuration instruction, wherein the configuration instruction may be issued to the refrigerator 10 by a user.
Before the step S504 and after the step S502, the configuration method further includes: the driving module 220 is started, and the driving module 220 is controlled to drive the camera 210 to be screwed out of the gap of the top wall 111 of the storage compartment 110. The curved arrow in fig. 4 shows the unscrewing path of the camera head 210. The drive module 220 may include a drive motor 221 and a transmission assembly 222. The driving motor 221 may be, but is not limited to, a stepping motor. The transmission assembly 222 may be in transmission connection with the output shaft of the driving motor 221 and the camera 210, and may be a gear set, for example. Those skilled in the art should easily know the specific structure of the driving module 220 based on the embodiment, and the detailed description is omitted here.
After determining that the refrigerator 10 enters the configuration mode, the driving module 220 is controlled to drive the camera 210 to screw out or screw in the gap of the top wall 111 of the storage compartment 110, so that the camera 210 of the embodiment can flexibly switch the working state, and under the condition that the camera 210 is in the non-working state, the camera 210 is embedded in the gap of the top wall 111 of the storage compartment 110, so that the storage space occupied by the camera 210 can be reduced or avoided, and the storage space utilization rate of the refrigerator 10 is improved.
Under the condition that camera 210 need switch into operating condition, through unscrewing camera 210 roof 111 breach, can make camera 210 switch over to operating condition fast, "live in the head and shoot the article of storing in storing room 110" to shoot comprehensive storing information "lightly and easily".
The step S504 may include: it is determined that the camera 210 is at a preset first viewing angle, and the driving module 220 is controlled to drive the camera 210 to rotate from the first viewing angle toward a preset second viewing angle, wherein an included angle between the first viewing angle and the second viewing angle is greater than or equal to 90 °. The included angle between the first visual angle and the second visual angle is set to be greater than or equal to 90 degrees, so that the storage condition of the storage chamber 110 can be comprehensively reflected by the image shot by the camera 210 in the rotating process.
When the camera 210 is at the first predetermined viewing angle, the shooting viewing angle of the camera 210 horizontally faces the inner side of the storage compartment 110, and the horizontal direction is parallel to the front-back direction of the refrigerator 10. When the camera 210 is at the preset second viewing angle, in this embodiment, the shooting viewing angle of the camera 210 may be vertically toward the inner side of the storage compartment 110, wherein the vertical direction is parallel to the height direction of the refrigerator 10, so that the included angle between the first viewing angle and the second viewing angle is equal to 90 °. In some optional embodiments, the included angle between the first viewing angle and the second viewing angle may be any value greater than 90 °, for example, 120 ° or 150 °, and at this time, the gap of the top wall 111 of the storage compartment 110 needs to be correspondingly deepened, and the rotatable range of the camera 210 may be increased.
The step S506 may include: whether a preset first identifier 500 exists in an image shot by the camera 210 or not is judged, if yes, the shooting visual angle of the camera 210 is obtained and recorded, and a first boundary of the shooting boundary is determined according to the shooting visual angle. Wherein an image in which the preset first identifier 500 exists may be named a first image. The shooting angle of view of the camera 210 is a shooting angle of view when the camera 210 shoots the first image, and may be named as a first shooting angle of view. In some further embodiments, the first capturing perspective may also refer to the capturing perspective of the camera 210 when the first marker 500 is centered in the first image.
The step S506 may further include: and judging whether a preset second identifier 600 exists in the image shot by the camera 210, if so, acquiring and recording the shooting visual angle of the camera 210, and determining a second boundary of the shooting boundary according to the shooting visual angle. Wherein, an image in which the preset second identifier 600 exists may be named as a second image. The shooting angle of view of the camera 210 is a shooting angle of view when the camera 210 shoots the second image, and may be named as a second shooting angle of view. In some further embodiments, the second capturing perspective may also refer to the capturing perspective of the camera 210 when the second marker 600 is centered in the second image.
By presetting the first identifier 500 and the second identifier 600 in the refrigerator 10, determining the first boundary of the camera shooting boundary according to the shooting visual angle at which the camera 210 shoots the first identifier 500, and determining the second boundary of the camera shooting boundary according to the shooting visual angle at which the camera 210 shoots the second identifier 600, the camera shooting boundary and the camera shooting area can be determined only by judging whether the image shot by the camera 210 contains the specific identifier, which is beneficial to simplifying the configuration process of the camera shooting area of the refrigerator 10.
The camera 210 may be in data connection with the control device in advance, so that the image captured by the camera 210 may be transmitted to the control device for processing (e.g., recognizing the first identifier 500, the second identifier 600, the item information, or the characteristic parameters of the image, etc.).
After the second identifier 600 is shot by the camera 210, the camera 210 can be closed, and the driving module 220 can drive the camera 210 to reset to the gap of the top wall 111 of the storage compartment 110. After the camera 210 is reset, the driving module 220 may be turned off.
In some embodiments, after the step S508, the configuring method may further include: the view angle range of the camera 210 is determined according to the image pickup area, and the shooting frequency of the camera 210 for the image pickup area is configured according to the view angle range. The view angle range of the camera 210 refers to an included angle between the first photographing view angle and the second photographing view angle. The shooting frequency of the camera 210 refers to the number of times the camera 210 shoots an image per unit time.
Using the above method, after the configuration mode is started, the refrigerator 10 can configure not only the image pickup area but also the image pickup frequency of the camera 210. When the shooting area is wide and the camera 210 needs to continuously shoot a plurality of images, the overlapping rate between adjacent images can be reduced by reasonably configuring the shooting frequency of the camera 210, so that the visual effect of information display is guaranteed, the image processing difficulty of the subsequent process is reduced, and multiple purposes are achieved.
The step of configuring the shooting frequency of the camera 210 for the shooting area according to the angle of view range includes: and determining the driving parameters of the driving module 220 according to the viewing angle range, and determining the shooting frequency of the camera 210 according to the driving parameters. The driving parameter of the driving module 220 may refer to a rotation rate at which the driving module 220 rotates the camera 210. In the step of configuring the driving parameters of the driving module 220 according to the viewing angle ranges, the preset value ranges of a plurality of viewing angle ranges can be obtained, the value range of each viewing angle range is correspondingly provided with a driving parameter of the driving module 220, and the driving parameter corresponding to the value range of the viewing angle range of the camera 210 is used as the driving parameter of the driving module 220.
In the step of determining the shooting frequency of the camera 210 according to the driving parameters, the pre-stored view angle change range of a single image shot by the camera 210 can be obtained, the ratio between the rotation rate of the driving module 220 driving the camera 210 to rotate and the view angle change range of a single image shot by the camera 210 is calculated, and the ratio is used as the shooting frequency of the camera 210. The range of the angle of view of the single image captured by the camera 210 is an angle between the center of the camera 210 and two boundaries of the single image. For example, if the variation range of the viewing angle of a single image captured by the camera 210 is 5 °, and the rotation rate of the driving module 220 driving the camera 210 to rotate is 1 °/s, the capturing frequency of the camera 210 is 0.2 times/s.
In other embodiments, after step S508, the configuring method may further include: the characteristic parameters of the image shot by the camera 210 are obtained, the characteristic parameters include at least one of brightness, resolution and contrast, and shooting light rays for the shooting area are configured according to the characteristic parameters of the image. In the process of acquiring the characteristic parameters of the image captured by the camera 210, any one of the images may be selected for processing.
Each characteristic parameter is preset with a reference value. In the step of configuring the shooting light for the shooting area according to the characteristic parameters of the image, if the characteristic parameters of the image do not reach the corresponding preset reference values, the shooting light intensity of the shooting area can be correspondingly improved, which is beneficial to improving the shooting effect of the camera 210.
