After the description of the cup holder body and the driving mechanism, the description of the control method of the controller will be continued by taking the door of the driver's seat as an example, that is, the description of the method for controlling the retractable cup holder in the vehicle shown in fig. 3 provided by the present application is provided, and the method is applied to the controller; the cup holder body is movably arranged in the mounting position of the vehicle door (the mounting position refers to the area where the first cavity 3 and the second cavity 4 of the cup holder body and the driving mechanism are arranged); the method comprises the following steps:
step S31, acquiring a first real-time image acquired by image acquisition equipment; wherein the first real-time image is an image of the cup holder body not being ejected from the mounting position.
The image acquisition equipment is arranged near the top of a front windshield in front of the driver seat, faces the driver seat, and is always arranged in a picture of the image acquisition equipment. And monitoring the vicinity of the mounting position by using an image acquisition device, and acquiring a first real-time image (the first real-time image is an image of the cup bracket body which is stored in the mounting position and is not popped up). The controller acquires the first real-time image from the image pickup device (or the image pickup device transmits the first real-time image to the controller) to perform step S32.
Step S32, comparing the first real-time image with the original image to obtain the distinguishing image characteristics; wherein, the original image is: under the condition that the cup stand body is not popped out from the mounting position and the image change does not occur within a first preset time, the image is acquired by the image acquisition equipment.
The controller acquires an original image in advance, wherein the original image refers to an image of the cup holder body which is stored in the mounting position and has no change in picture within a first preset time (for example, 10S). The controller receives the first real-time image, compares the first real-time image with the original image, and when the first real-time image and the original image have no difference, namely no image characteristic difference exists between the first real-time image and the original image, the controller considers that the picture has no change, and the user does not intend to place a cup, so that no action is needed, and the user only needs to continue to monitor the position close to the installation position by the image acquisition equipment.
When there is a difference between the first real-time image and the original image, that is, there is a difference image feature between the first real-time image and the original image, it is considered that there is a change in the picture of the image capturing apparatus, and a cup may appear, and in order to further determine whether there is a cup in the picture captured by the image capturing apparatus, step S33 is continuously performed.
In step S33, it is determined whether the difference image feature matches the cup-like object image feature.
The cup-shaped object image characteristics are obtained in advance according to the shape characteristics of various types of water cups. The distinguishing image characteristics are matched with the cup-shaped object image characteristics, whether a cup exists in a picture acquired by the image acquisition equipment or not can be determined according to a matching result, and when the cup exists in the picture, the cup can be placed.
The cup-shaped object image recognition method and the cup-shaped object image recognition device have the advantages that the first real-time image and the original image are compared, so that the distinguishing image characteristics can be rapidly acquired when the image changes, the distinguishing image characteristics are compared with the cup-shaped object image characteristics, and then whether the cup exists in the image of the image acquisition device or not is determined. Because the background of the picture scene shot by the image acquisition equipment is unchanged after the installation position and the angle of the image acquisition equipment are fixed, the first real-time image is compared with the original image to obtain the distinguishing image characteristics, and then the distinguishing image characteristics are compared with the cup-shaped object image characteristics, so that all the image characteristics in the first real-time image can be prevented from being compared with the cup-shaped object image characteristics one by one, the matching time is further shortened, and the computing resources are saved.
When the scene of the cup-shaped object appears in the picture of the image acquisition equipment, the cup is held by hands, the hands can shield the cup, the matching degree of the distinguishing image characteristics obtained by the controller and the image characteristics of the cup-shaped object is not high, the controller possibly considers that the distinguishing image characteristics are not matched with the image characteristics of the cup-shaped object, and then the driving mechanism is not controlled to pop out the cup holder body from the installation position. In order to avoid this, step S33 may specifically include (i.e., step S331 to step S334):
in step S331, the similarity ratio of the distinguishing image feature and the cup-shaped object image feature is determined.
The similarity between the distinguishing image features and the cup-shaped object image features is determined first, and when the similarity is low, it cannot be accurately analyzed whether the first real-time image has the intention of placing the cup, so step S332 is executed for further analysis and judgment. When the degree of similarity is high, it can be determined that there is an intention to place a cup in the first real-time image, i.e., step S334 is performed.
Step S332, when the similarity proportion does not exceed a preset proportion threshold value, judging whether the human body gesture in the first real-time image is a preset human body gesture;
and comparing the similar proportion with a preset proportion threshold value to determine the similarity degree. When the similarity ratio does not exceed the preset ratio threshold, the similarity degree is considered to be low, and whether the human body gesture is the preset human body gesture of holding the cup by hand needs to be further judged. When the human body gesture is not the preset human body gesture, it means that the cup does not exist in the first real-time image, and therefore, the distinguishing image feature may be considered to be not matched with the cup-shaped object image feature.
In step S333, if yes, the distinguishing image feature is matched with the cup-shaped object image feature.
When the human body gesture is the preset human body gesture, the cup-shaped object does exist in the first real-time image, and only the cup is shielded by the human hand, so that the distinguishing image feature can be considered to be matched with the cup-shaped object image feature.
In step S334, when the similarity ratio exceeds the preset ratio threshold, the distinguishing image feature is matched with the cup-shaped object image feature.
When the similarity ratio exceeds a preset ratio threshold, the similarity degree is high, and the matching of the distinguishing image features and the cup-shaped object image features can be directly determined.
Step S34, if matching, judging whether the cup-shaped object is in the preset imaging area and keeping a second preset time; and the corresponding imaging area of the installation position in the first real-time image is in a preset imaging area.
In case the distinguishing image features match with the cup-shaped object image features, meaning that the cup is indeed present in the first real-time image, but needs to be placed, further analysis is needed. In order to determine whether a cup-shaped object appearing in the first real-time image needs to be placed, the method and the device set a preset imaging area, and the preset imaging area surrounds the corresponding imaging area of the installation position in the first real-time image. For example, if the imaging area corresponding to the installation position in the first live image is a circle (denoted as a first circle), the preset imaging area is a circle (denoted as a second circle) larger than the installation position, and the first circle is included in the second circle.
When the cup-shaped object is in the preset imaging area and is kept for a second preset time (for example, 3 seconds), the cup-shaped object in the first real-time image is considered to have a placement requirement, and step S35 is executed. When the cup-shaped object is not in the preset imaging area, or when the cup-shaped object is in the preset imaging area but is not kept for the second preset duration, the cup-shaped object in the first real-time image is not required to be placed, no action is performed, and only the new first real-time image needs to be continuously acquired through the image acquisition equipment.
Before performing step S35, in order to determine whether the size of the cup-shaped object matches the size of the cup holder body, the following steps (including step 1 and step 2) may be performed:
step 1, determining the pixel proportion of the cup-shaped object in the first real-time image.
Whether the size of the cup-shaped object is matched with the size of the cup holder body or not can be estimated through the pixels occupied by the cup-shaped object in the first real-time image and the pixels occupied by the cup holder body in the first real-time image. And the background in the picture acquired by the image acquisition equipment after the position is fixed is determined, so that the number of pixels occupied by each object in the background is determined, namely the number of pixels occupied by the installation position is determined. Therefore, it is possible to determine whether the size of the cup-shaped object matches the size of the cup holder body by determining the pixel proportion of the cup-shaped object in the first real-time image.
And 2, when the pixel ratio exceeds the first ratio threshold and does not exceed the second ratio threshold, executing a step of controlling the driving mechanism to pop the cup holder body out of the mounting position. Wherein the first duty ratio threshold is less than the second duty ratio threshold.
When the pixel ratio is between the first ratio threshold and the second ratio threshold, it means that the size of the cup-shaped object matches the size of the cup holder body, the cup-shaped object can be placed on the cup holder body, and the step S35 can be continued. When the pixel proportion is lower than the first proportion threshold, it means that the cup-shaped object is too small, and if the cup-shaped object is placed on the cup holder body, the cup-shaped object may roll over when shaking occurs during the driving of the automobile, and there is a safety hazard, and therefore, the cup holder body cannot be ejected, and step S35 cannot be executed. When the pixel proportion exceeds the second proportion threshold, it means that the size of the cup-shaped object is too large to be placed on the cup holder body, and it is not necessary to perform step S35.
And step S35, if yes, controlling the driving mechanism to eject the cup holder body from the mounting position, so that the cup holder body bears the cup-shaped object.
When the cup-shaped object is in the preset imaging area and keeps the second preset duration, which means that the cup-shaped object in the first real-time image has a placing requirement, the driving mechanism can be controlled to pop the cup bracket body out of the mounting position, so that the cup bracket body can place the cup-shaped object.
This application sets up cup bracket body in the door, acquires near the first real-time image of mounted position through image acquisition equipment to whether cup object appears in the picture in the certain picture of dependence on first real-time image, when cup object appears, whether the cup object in the first real-time image of analysis has the demand of placing, when having the demand of placing, control actuating mechanism pops out cup bracket body from the door in, in order to accept cup object. The cup holder body which is not used can be stored in the vehicle door, so that the space in the vehicle is saved; whether personnel have the intention of placing the cup in can also the automatic identification car, when having the intention of placing the cup, pop out the cup bracket body from the door in the automation, and then can make things convenient for personnel in the car to place the cup, also can avoid the driver to drive the in-process because of can't opening the cup bracket body of accomodating and be distracted, improve and drive the security.
After the cup is placed on the popped up cup holder body, a driver can directly take off the cup from the cup holder body for drinking, and in order to identify whether the cup is temporarily separated from the cup holder body, the application provides a further optimization scheme on the basis of the technical scheme, and the scheme is as follows:
after controlling the drive mechanism to eject the cup holder body from the mounting position such that the cup holder body carries the cup-shaped object, the method further comprises:
step S41, acquiring a second real-time image acquired by the image acquisition equipment; wherein, the second real-time image is: the image after the cup holder body is ejected from the mounting position.
And recording the image after the cup holder body is popped out from the mounting position as a second real-time image. The controller obtains a second real-time image acquired by the image acquisition equipment to determine the time for recovering the cup bracket body into the installation position.
In step S42, it is determined whether the cup-shaped object is within the preset imaging area.
According to the method and the device, whether the cup-shaped object is in the preset imaging area is judged by judging whether the cup-shaped object has the image characteristics of the cup-shaped object in the preset imaging area in the second real-time image. When the cup-shaped object leaves the preset imaging area, it means that the cup holder body may no longer be required and needs to be retrieved into the vehicle door. To further determine whether to retract the cup holder body into the door, the process proceeds to step S43. When the cup-shaped object stays in the preset imaging area, the cup bracket body needs to be used continuously and cannot be recovered into the vehicle door, and the cup bracket body is kept in the popped state.
And step S43, if not, judging whether the duration that the cup-shaped object is not in the preset imaging area reaches a third preset duration.
When the cup-shaped object is not in the preset imaging area, the cup-shaped object may not be required to be placed in the cup holder body any more, and then the cup-shaped object needs to be recycled into the vehicle door. The present application performs step S44 by monitoring the time period during which the cup-shaped object leaves the preset imaging area, and when the time period exceeds a third preset time period (for example, 10S), this means that the cup-shaped object does not need to be placed on the cup holder body. When the time length of the cup-shaped object leaving the preset imaging area does not exceed the third preset time length, the cup-shaped object returns to the preset imaging area, which means that the cup-shaped object still needs to be placed on the cup stand body, and the cup stand body does not need to be recovered into the vehicle door.
And step S44, controlling the driving mechanism to recover the cup holder body into the mounting position when the time length that the cup-shaped object is not in the preset imaging area reaches a third preset time length.
When the time length that the cup-shaped object is not in the preset imaging area reaches the third preset time length, the controller controls the driving mechanism to recover the cup holder body into the mounting position, and executes the step S31 again to obtain the first real-time image and monitor whether the cup-shaped object appears in the first real-time image.
Whether a cup to be placed exists near the mounting position is monitored through the image acquisition equipment, the cup holder body is popped out of the mounting position when the cup is required to be placed, and the cup holder body is recovered to the mounting position when the cup is not required to be placed, so that the cup holder body is recovered to the mounting position when the cup holder body is not required, and the internal space of an automobile is saved; on the other hand, the controller automatically controls the cup bracket body to be retracted or popped up through image analysis, so that the distraction of a driver due to the fact that the cup bracket body which is stored cannot be opened in the driving process can be avoided, and the driving safety is improved.
On the basis of the above technical solution, before acquiring the first real-time image acquired by the image acquisition device, the method further includes:
and step S51, acquiring a third real-time image acquired by the image acquisition device.
And step S52, judging whether the third real-time image has a face image.
And step S53, if yes, executing the step of acquiring the first real-time image acquired by the image acquisition device.
When there is no person in the automobile or no person in the driver seat of the automobile, there is no need to compare the first real-time image with the original image, and at this time, the controller may be set to the sleep mode. In the sleep mode, in order to save the calculation resources of the controller, the controller only needs to judge whether the acquired third real-time image has a face. When the third real-time image does not have a human face, which means that no person is currently in the driver seat, the controller may continue to be in the sleep mode. When the controller recognizes that the third real-time image contains the face image, the controller is awakened, the sleep mode is switched to the working mode, and the steps S31-S35 are executed to determine whether the cup holder body needs to be ejected from the installation position.
By monitoring whether a human face exists in the picture of the image acquisition equipment or not, the controller is controlled to switch between the sleep mode and the working mode, the calculation load of the controller can be reduced, and calculation resources and automobile energy (such as electric energy) can be saved.
