[0057] The following will describe the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0058] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining authorization from the owner of the corresponding device.

[0059] First, the application scenario of the present disclosure will be introduced. The present disclosure is applied in the scenario of vehicle lane change. With the increase in the vehicle ownership rate, the incidence of traffic accidents has also been increasing year by year. For example, when a vehicle changes lanes, it is easily affected by the blind spot of vision, resulting in traffic accidents.

[0060] During the process of a vehicle changing lanes, the user needs to observe the environment around the vehicle and the positions of other vehicles to determine the best lane-changing position, so as to ensure driving safety. However, when the user observes the environment around the vehicle, the line of sight is easily blocked, resulting in a blind spot of vision and the inability to comprehensively understand the information of the surrounding environment, thus leading to traffic accidents. For example, when a vehicle changes lanes to the right, the user can observe the information of other vehicles on the right rear of the vehicle through the interior rearview mirror. However, the headrest of the rear seat of the vehicle will block the user's line of sight, creating a blind spot of vision, making the user unable to understand the information of other vehicles on the right rear, unable to determine the best lane-changing position, and easily colliding with other vehicles, increasing the probability of accidents.

[0061] To solve the above problems, the present disclosure provides a method, apparatus, storage medium, and electronic device for determining line-of-sight occlusion; obtaining focus information of a user's eyes; determining mirror focus information corresponding to the focus information in the vehicle's interior rearview mirror; determining a target visible area of the interior rearview mirror and the headrest of the vehicle's rear seat on a preset plane according to the mirror focus information; determining the occlusion of the headrest on the user's line of sight according to the target visible area and the lane width of the target lane; the target lane includes the current lane in which the vehicle is traveling and the adjacent lane of the current lane; the occlusion situation indicates whether the headrest occludes the user's line of sight; through the above technical solution, the target visible area behind the vehicle can be determined through the user's eyes, the vehicle's interior rearview mirror, and the headrest, and the determination of the occlusion of the headrest on the user's line of sight can be realized according to the target visible area, so that the user can understand the occlusion of the headrest on the line of sight and improve driving safety.

[0062] Figure 1 is a flowchart of a method for determining line-of-sight occlusion shown according to an exemplary embodiment. As Figure 1 shown, the method may include the following steps:

[0063] S101. Obtain focus information of the user's eyes.

[0064] Exemplarily, the focus information may include left-eye focus information and right-eye focus information; the focus information may include position information of the focus.

[0065] S102. Determine mirror focus information corresponding to the focus information in the vehicle's interior rearview mirror.

[0066] Exemplarily, based on the interior rearview mirror, a mirror image point corresponding to the focus information can be determined, and the mirror image point is used as the mirror focus information.

[0067] S103. Determine a target visible area of the interior rearview mirror and the headrest of the vehicle's rear seat on a preset plane according to the mirror focus information.

[0068] Exemplarily, the preset plane may be a reference plane set by the user for determining the projection areas of the interior rearview mirror and the headrest, so that the target visible area can be determined according to the projection areas.

[0069] S104. Determine the occlusion of the headrest on the user's line of sight according to the target visible area and the lane width of the target lane.

[0070] Wherein, the target lane includes the current lane in which the vehicle is traveling and the adjacent lane of the current lane; the occlusion situation indicates whether the headrest occludes the user's line of sight.

[0071] Exemplarily, the lane width can be a marking line of the lane width at a preset distance behind the vehicle; the preset distance can be set by the user and is not limited herein.

[0072] Through the above technical solution, the target visible area behind the vehicle can be determined through the user's eyes, the interior rearview mirror of the vehicle, and the headrest, and the determination of the blocking situation of the headrest on the user's line of sight can be realized according to the target visible area, enabling the user to understand the blocking situation of the headrest on the line of sight and improving driving safety.

[0073] Figure 2 is based on Figure 1 The flowchart of a method for determining line-of-sight occlusion shown in an exemplary embodiment of. As Figure 2 shown, the above step S103 may include:

[0074] S1031. For each eye of the user, according to the mirror focus information, determine the visible area corresponding to each eye of the interior rearview mirror and the headrest on the preset plane.

[0075] S1032. Take the union of the visible areas corresponding to each eye as the target visible area.

[0076] In some embodiments, the mirror focus information may include left-eye mirror focus information or right-eye mirror focus information; the visible area may include a left-eye visible area or a right-eye visible area. The left-eye visible area corresponding to the left eye of the interior rearview mirror and the headrest on the preset plane can be determined according to the left-eye mirror focus information. The right-eye visible area corresponding to the right eye of the interior rearview mirror and the headrest on the preset plane can be determined according to the right-eye mirror focus information. Take the union of the left-eye visible area and the right-eye visible area as the target visible area. In this way, the corresponding visible areas can be determined respectively according to the mirror focus information of the two eyes, and thus the target visible area can be determined according to the visible areas.

[0077] In some other embodiments, the above step of, for each eye of the user, according to the mirror focus information, determining the visible area corresponding to each eye of the interior rearview mirror and the headrest on the preset plane may include: determining the first projection area of the interior rearview mirror on the preset plane according to the mirror focus information; determining the second projection area of the headrest in the first projection area according to the mirror focus information; projecting the second projection area relative to the ground according to the mirror focus information to obtain a third projection area; and taking the third projection area as the visible area.

[0078] Exemplarily, the mirror focus information may include left-eye mirror image focus information or right-eye mirror image focus information; the visible region may include a left-eye visible region or a right-eye visible region. The first projection region of the interior rearview mirror on the preset plane may be determined according to the left-eye mirror image focus information; the second projection region of the headrest in the first projection region may be determined according to the left-eye mirror image focus information; the second projection region may be projected relative to the ground according to the left-eye mirror image focus information to obtain a third projection region; and the third projection region may be used as the left-eye visible region. The first projection region of the interior rearview mirror on the preset plane may be determined according to the right-eye mirror image focus information; the second projection region of the headrest in the first projection region may be determined according to the right-eye mirror image focus information; the second projection region may be projected relative to the ground according to the right-eye mirror image focus information to obtain a third projection region; and the third projection region may be used as the right-eye visible region. In this way, the visible region of the user can be determined by combining the interior rearview mirror and the headrest, improving the accuracy of determining the visible region.

[0079] Figure 3 is a schematic diagram of a visible region shown according to an exemplary embodiment. As Figure 3 shown, the visible region includes region S, region K1, and region K2; region S may be the projection region of the interior rearview mirror on the preset plane; region K1 may be the left-eye visible region determined on the projection region of the interior rearview mirror according to the left-eye mirror image focus information; and region K2 may be the right-eye visible region determined on the projection region of the interior rearview mirror according to the right-eye mirror image focus information.

[0080] Figure 4 is according to Figure 3 of an exemplary embodiment shown. As Figure 4 shown, the visible region may include region N1 and region N2. Region N1 may be the left-eye projection region obtained by projecting the left-eye visible region K1 onto the ground according to the left-eye mirror image focus information; and region N2 may be the right-eye projection region obtained by projecting the right-eye visible region K2 onto the ground according to the right-eye mirror image focus information. The union of region N1 and region N2 may be the target visible region behind the vehicle.

[0081] Figure 5 is according to Figure 2 of an exemplary embodiment shown in another flowchart of a method for determining line-of-sight occlusion. As Figure 5 shown, step S104 above may include:

[0082] S1041. Determine the distance corresponding to the intersection position of the target visible region and the lane width marking line according to the mirror focus information.

[0083] Exemplarily, the intersection position between the boundary line of the target visible area and the marking line of the lane width can be determined, and the distance of the intersection position can be determined.

[0084] S1042. Determine the blocking situation of the headrest on the user's line of sight according to the distance.

[0085] In some embodiments, the determining the blocking situation of the headrest on the user's line of sight according to the distance may include: when it is determined that the distance is greater than or equal to a preset distance threshold, determining that the headrest does not block the user's line of sight; or, when it is determined that the distance is less than the preset distance threshold, determining that the headrest blocks the user's line of sight.

[0086] Exemplarily, the preset distance threshold may be a threshold determined according to the lane width of the adjacent lane of the current lane; the preset distance threshold may be half of the width of a single lane. For example, the preset distance threshold may be in the range of 1.5 - 2.0 m, such as 1.5 m, 1.75 m or 2.0 m, etc., which is not limited herein. In this way, the blocking situation of the headrest on the user's line of sight can be determined according to the positional relationship between the target visible area and the lane width, so that the user can timely understand whether there is a visual blind area.

[0087] Figure 6 is a schematic diagram of a method for determining line-of-sight occlusion shown according to an exemplary embodiment. As Figure 6 shown, at the vehicle position, according to the mirror focus information, the interior rearview mirror and the headrest of the vehicle are projected relative to the ground to obtain an invisible area and a target visible area. The target visible area includes a partial area of the current lane and a partial area of the adjacent lane. It can be Figure 6 seen that the distance between the intersection positions of the target visible area and the marking line of the lane width and the boundary line of the adjacent lane (the boundary line refers to the boundary line where the adjacent lane meets the current lane) is D; when it is determined that the distance D is greater than or equal to the preset distance threshold, it is determined that the headrest does not block the user's line of sight; or, when it is determined that the distance D is less than the preset distance threshold, it is determined that the headrest blocks the user's line of sight.

[0089] S105. When it is determined that the occlusion situation is that the headrest blocks the user's line of sight, output a prompt message.

[0090] Wherein, the prompt message is used to prompt that the headrest blocks the user's line of sight.

[0091] Exemplarily, the prompt message can be an audio prompt message or a text prompt message. The prompt message can be output through the multimedia device of the vehicle. For example, an audio device or a display device, etc., which is not limited herein. In this way, when it is determined that the headrest blocks the user's line of sight, the user can be prompted in a timely manner, so that the user can timely understand the occlusion of the headrest on the user's line of sight and reduce the occurrence of traffic accidents.

[0092] It should be noted that a prompt message can also be output when it is determined that the occlusion situation is that the headrest does not block the user's line of sight. In this way, the user can timely understand the occlusion of the headrest on the user's line of sight.

[0093] Figure 8 is a flowchart of another method for determining line-of-sight occlusion shown according to an exemplary embodiment. As Figure 8 shown, the method may include the following steps:
