[0031] Under normal circumstances, the cameras arranged in the towing vehicle of a towed trailer are calibrated based on the vehicle itself. However, during driving, users may not be able to observe the status of the trailer, which may cause safety problems such as collisions. To address this issue, embodiments of the present disclosure provide a method for observing the trailer status, which will be introduced below in conjunction with specific embodiments.

[0032] Figure 1 FIG. is a flowchart of a method for observing the trailer status provided by an embodiment of the present disclosure. This method can be executed by a trailer status observation device, which can be implemented in software and / or hardware and can be configured in an electronic device, such as a server or a terminal. Specifically, the terminal includes a vehicle head unit, a computer, a tablet computer, etc.

[0033] As Figure 1 shown, the method for observing the trailer status provided in this embodiment includes the following steps.

[0034] S110. In response to meeting a preset condition, control a target camera to rotate so that the target camera rotates to a target position and capture a target image. The target camera is a surround-view camera, and the target image is an image including the environment around the trailer or the trailer hitch.

[0035] In embodiments of the present disclosure, the preset condition includes at least one of a user's selection operation for the trailer perspective, a user's selection operation for the trailer hitch perspective, reaching a first preset time interval, and reaching a preset driving distance.

[0036] The target camera can be a surround-view camera, specifically including side-view cameras and a rear-view camera. Among them, the side-view cameras are respectively installed on the left and right rearview mirrors of the towing vehicle; the rear-view camera is installed at the rear of the towing vehicle and in the middle position left and right, such as on the trunk or spare tire, etc., and is specifically set according to different vehicle models.

[0037] The target position can be understood as the best position to observe the trailer status.

[0038] The target image can be an image including a part of the trailer (such as the lower part of the trailer) and the road around the trailer, an image including the trailer hitch, a part of the trailer adjacent to the trailer hitch, and the road around the trailer hitch, etc.

[0039] Specifically, in response to meeting the preset condition, the electronic device controls the target camera corresponding to the preset condition to rotate, rotates the target camera to the best position to observe the trailer status, and then controls the target camera to capture an image. After the target camera captures the image, it uploads the image to the electronic device.

[0040] S120. Receive the target image uploaded by the target camera and display it for the user to view the trailer status.

[0041] In the embodiment of the present disclosure, the electronic device receives the target image uploaded by the target camera and displays the target image through a display device such as a vehicle control display screen, etc., for the user such as the driver to understand the environment around the trailer through the target image and determine the trailer status.

[0042] Among them, the electronic device can display the target images collected by the target camera within a preset time period in the form of images.

[0043] In the embodiment of the present disclosure, in response to meeting the preset conditions, the target camera can be controlled to rotate so that the target camera rotates to the target position and captures the target image. The target camera is a surround-view camera, and the target image is an image including the environment around the trailer or the trailer hitch; receive the target image uploaded by the target camera, and display the target image after receiving the target image for the user to view the trailer status. Thus, by adjusting the angle of the target camera, an image including the environment around the trailer or the trailer hitch is obtained and displayed, so that the user can view the status of the trailer during vehicle driving, thereby avoiding collisions, etc., and improving driving safety.

[0044] Based on the above embodiment of the present disclosure, by utilizing the electrically adjustable feature of the surround-view camera, the user can independently select the viewing angle of the trailer, and the camera can automatically adjust to the target position and output the image, facilitating the user to observe the trailer status from different perspectives.

[0045] In some embodiments of the present disclosure, when the preset condition is the user's selection operation of the trailer viewing angle, the target camera is a side-view camera. Specifically, as Figure 2 shown, when the preset condition is the user's selection operation of the trailer viewing angle, controlling the target camera to rotate so that the target camera rotates to the target position may specifically include the following steps:

[0046] S210. Determine the first angle for observing the trailer status.

[0047] In the embodiment of the present disclosure, the first angle can be understood as the best angle for observing the trailer status.

[0048] Furthermore, determining the first angle for observing the trailer status may specifically include: obtaining the trailer type corresponding to the trailer and the target parameters corresponding to the trailer; based on the target parameters and the correspondence between the trailer parameters and the trailer status observation angle, determining the first angle.

[0049] In the embodiments of the present disclosure, the trailer types may include conventional trailers, cars, trucks, boats, temporary vacation homes, horse carriages, etc.

[0050] The target parameters mainly include the length and width of the trailer.

[0051] The correspondence between the trailer parameters and the observation angle of the trailer state is the pre-set correspondence between different trailer parameters and the optimal angle for the camera to observe the trailer state.

[0052] Specifically, the electronic device may obtain the trailer type and the corresponding target parameters of the trailer from the preset database based on the identification information of the vehicle to be observed. After obtaining the target parameters, it obtains the correspondence between the trailer parameters and the observation angle of the trailer state from the preset database, determines the optimal observation angle of the trailer corresponding to the target parameters based on this correspondence, and determines this angle as the first angle.

[0053] S220. Control the side-view camera to rotate based on the first angle so that the side-view camera rotates to the target position, where the trailer body image in the target image corresponding to the target position occupies a first preset ratio of the width of the target image, or the trailer body image occupies a second preset ratio of the length of the target image.

[0054] In the embodiments of the present disclosure, the first preset ratio and the second preset ratio vary according to the vehicle's shape, the camera arrangement position, height, etc.

[0055] Specifically, after the electronic device obtains the first angle, it controls the side-view camera to rotate based on the first angle so that the side-view camera rotates to the position corresponding to the first angle, that is, the target position, and controls the side-view camera to collect the target image at the target position. Depending on the vehicle driving state, the target image collected at the target position corresponding to the first angle is different.

[0056] In some examples, when the vehicle is in a straight driving state, the trailer body image in the target image collected at the target position occupies one-third of the width of the target image.

[0057] In other examples, when the vehicle is in a turning driving state, the trailer body image in the target image collected at the target position occupies one-sixth of the length of the target image.

[0058] In the embodiments of the present disclosure, when responding to the user's selection operation of the trailer view angle, it is possible to control the side-view camera to rotate to the optimal angle for observing the trailer according to the type of the trailer and parameters such as the length and width of the trailer, obtain the target image corresponding to the target position at the angle, and display the target image, enabling the user to observe the trailer state in a timely and accurate manner, improving the flexibility of observing the trailer state and driving safety.

[0059] In some other embodiments of the present disclosure, when the preset condition is the user's selection operation on the trailer hitch perspective, the target camera is a rear-view camera. As Figure 3 shown, when the preset condition is the user's selection operation on the trailer hitch perspective, control the target camera to rotate so that the target camera rotates to the target position and collect a target image. Specifically, it may include the following steps:

[0060] S310. Determine the type of the trailer ball on the trailer hitch.

[0061] In the embodiments of the present disclosure, the types of trailer balls include two types: the position of the trailer ball is fixed and the position of the trailer ball is not fixed. When the trailer hitch is a factory-supplied trailer hitch, such as an electric trailer hitch, the relative position of the trailer ball is fixed, that is, the position of the trailer ball is fixed; if the manufacturer only provides a square opening of the trailer hitch, the user can install different styles of trailer hitches at will. At this time, the relative position of the trailer ball is not fixed, that is, the position of the trailer ball is not fixed.

[0062] Specifically, the electronic device can obtain the information of the trailer ball from the preset database based on the identification information of the trailer, and then determine the type of the trailer ball on the trailer hitch. When the relative position of the trailer ball is not fixed, execute steps S320 - S330; when the relative position of the trailer ball is fixed, execute steps S340 - S370.

[0063] S320. When the position of the trailer ball on the trailer hitch is not fixed, control the rear-view camera to rotate and collect a trailer image, and perform recognition on the trailer image to obtain a recognition result.

[0064] Specifically, when the electronic device determines that the type of the trailer ball is that the position of the trailer ball is not fixed, control the rear-view camera to rotate, and during the rotation, control the rear-view camera to collect an image to obtain a trailer image, perform recognition on the trailer image, determine whether the trailer image contains a trailer ball, and when the trailer ball is included, the position of the trailer ball in the trailer image, so as to obtain a recognition result. Among them, the recognition of the trailer image can be any existing method for recognizing target objects in an image, such as extracting features from the trailer image through a machine learning model for recognition, etc., which is not limited herein.

[0065] S330. When the recognition result is that the trailer image contains the trailer ball on the trailer hitch, and the trailer ball is centered horizontally in the trailer image and the distance from the lower edge accounts for a third preset ratio of the total width of the image, determine the position corresponding to when the trailer image is collected as the target position, and determine the trailer image as the target image.

[0066] In the embodiments of the present disclosure, the third preset ratio may be different according to different vehicle shapes, camera arrangement positions, heights, etc. Exemplarily, the third preset ratio may be one-fifth.

[0067] Further, when the trailer ball is not included in the recognition result and / or the position of the trailer ball in the trailer image does not meet the preset requirements, the rear-view camera continues to rotate and capture the trailer image until the trailer ball is included in the recognition result and the position of the trailer ball in the trailer image meets the preset requirements.

[0068] S340. When the position of the trailer ball of the trailer hitch is fixed, obtain the first position of the trailer ball on the trailer and the second position of the rear-view camera.

[0069] Specifically, when the electronic device determines that the type of the trailer ball is that the position of the trailer ball is fixed, it obtains the first position of the trailer ball on the trailer and the second position of the rear-view camera from the preset database based on the identification information of the trailer and the identification information of the rear-view camera.

[0070] S350. Determine the relative position relationship between the trailer ball and the rear-view camera based on the first position and the second position.

[0071] In the embodiments of the present disclosure, the relative position relationship may include the horizontal distance and the vertical height difference between the trailer ball and the rear-view camera. Specifically, the method for determining the relative position relationship between the trailer ball and the rear-view camera is similar to the existing method for determining the relative position relationship between two objects, and will not be elaborated here.

[0072] S360. Calculate a second angle for observing the trailer state based on the relative position relationship and the parameters of the rear-view camera.

[0073] In the embodiments of the present disclosure, the second angle can be understood as the best angle for observing the trailer state through the trailer hitch. The target image corresponding to the position where the rear-view camera is at the second angle includes the trailer ball, and the trailer ball is centered horizontally in the target image and the distance from the lower edge accounts for a third preset ratio of the total width of the image.

[0074] Specifically, after the electronic device determines the relative position relationship between the trailer ball and the rear-view camera, it performs angle calculation based on the parameters of the rear-view camera such as the focal length and the field of view angle and the relative position relationship, and then obtains the second angle.

[0075] S370. Control the rear-view camera to rotate based on the second angle so that the rear-view camera rotates to the target position and captures the target image.

[0076] Specifically, after the electronic device obtains the second angle, it controls the rear-view camera to rotate based on the second angle so that the rear-view camera rotates to the target position and captures the target image.

[0077] In an embodiment of the present disclosure, when responding to a user's selection operation of the trailer hitch perspective, different methods can be selected to determine the optimal angle for observing the trailer according to the type of trailer ball on the trailer hitch for target image acquisition, so that the acquired target image can accurately reflect the state of the trailer and the environment around the trailer hitch, enabling the user to further understand the state of the trailer and further improving driving safety.

[0078] In some other embodiments of the present disclosure, when the preset condition is reaching a first preset time interval or reaching a preset driving distance, the target camera can be a side view camera and / or a rear view camera. The electronic device can control the target camera to rotate to determine the target angle for observing the trailer state and store the target angle; when responding to the user's selection operation of the trailer perspective and / or the user's selection operation of the trailer hitch perspective, the target angle is obtained, and based on the target angle, the corresponding target camera is controlled to rotate, and the output image is obtained for display.

[0079] In an embodiment of the present disclosure, after receiving the target image uploaded by the target camera and displaying it for the user to view the trailer state, the trailer state observation method may further include: in response to the user's selection operation of the tractor perspective or reaching a second preset time interval, controlling the target camera to rotate to the initial position.

[0080] In an embodiment of the present disclosure, after observing the trailer state, the target camera can be restored to the initial position by controlling the rotation of the target camera, so as to flexibly use the target camera to observe the state of the tractor.

[0081] Figure 4 It is a schematic structural diagram of a trailer state observation device provided by an embodiment of the present disclosure.

[0082] In an embodiment of the present disclosure, the trailer state observation device can be set in the electronic device and is understood as some functional modules in the above-mentioned electronic device. Specifically, the electronic device can be a server or a terminal, where the terminal specifically includes a car machine, a computer, a tablet computer, etc., which are not limited herein.

The target camera is a surround-view camera, and the target image is an image including the environment around the trailer or the trailer hitch; receive the target image uploaded by the target camera, and display the target image after receiving it for the user to view the trailer status. Thus, by adjusting the angle of the target camera, an image including the environment around the trailer or the trailer hitch is obtained and displayed, so that the user can view the status of the trailer during vehicle driving, thereby avoiding collisions and the like and improving driving safety.

[0087] In some embodiments of the present disclosure, the preset condition includes at least one of a user's selection operation for the trailer perspective, a user's selection operation for the trailer hitch perspective, reaching a first preset time interval, and reaching a preset driving distance. When the preset condition is a user's selection operation for the trailer perspective, the target camera is a side-view camera.

[0094] When the recognition result is that the trailer image contains a trailer ball on the trailer hitch, and the trailer ball is centered horizontally in the trailer image and the distance from the lower edge accounts for the third preset ratio of the total width of the image, the position corresponding to the acquisition of the trailer image is determined as the target position, and the trailer image is determined as the target image.

[0095] In some embodiments of the present disclosure, the camera control module 410 may further be specifically configured to, when the position of the trailer ball of the trailer hitch is fixed, obtain the first position of the trailer ball on the trailer and the second position of the rear-view camera;

[0098] Control the rear-view camera to rotate based on the second angle so that the rear-view camera rotates to the target position and acquires the target image.

[0099] In some embodiments of the present disclosure, the trailer state observation device 400 may further include a position restoration module.

[0100] The position restoration module may be configured to, after receiving the target image uploaded by the target camera and displaying it for the user to view the trailer state, in response to the user's selection operation for the tractor perspective or reaching the second preset time interval, control the target camera to rotate to the initial position.
