[0002] A Head Up Display (HUD) can project images on the windshield of a vehicle in real time, avoiding the driver from looking down at the dashboard, thereby improving driving safety. Before the HUD is put into use, the distortion parameters of the HUD need to be calibrated.

[0078] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0079] The following describes a method and apparatus for correcting distortion parameters, a vehicle, an electronic device, and a storage medium according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0080] Figure 1 A flowchart of a method for correcting distortion parameters provided in an embodiment of the present disclosure is provided.

[0081] like Figure 1 As shown, the method is applied to a vehicle computer, and the method comprises the following steps:

[0082] Step 101, in response to a vehicle being powered on, determining whether a first serial number of a target head-up display is consistent with a second serial number of a currently installed head-up display, wherein the first serial number is a serial number stored in the vehicle.

[0083] In order to better understand the correction of distortion parameters, such as Figure 2 As shown, Figure 2A flow chart of distortion parameter transmission provided for an embodiment of the present application; in order to ensure the accuracy of the distortion parameters of the HUD, it is necessary to determine whether the HUD has been replaced. The serial number of each HUD is different, so by comparing whether the serial numbers are consistent, it can be determined whether the HUD has been replaced; in the vehicle, the vehicle computer and the HUD are connected, and each time the vehicle is powered on, the vehicle computer obtains the second serial number of the currently installed HUD, and compares the second serial number with the first serial number of the target HUD stored in the vehicle computer, and determines whether the first serial number is consistent with the second serial number, so as to prepare for the subsequent correction of the distortion parameters, wherein the target HUD is the HUD installed for image distortion correction at the vehicle manufacturer.

[0084] Step 102: If it is determined that the first serial number is inconsistent with the second serial number, the first serial number is updated to the second serial number.

[0085] Before transmitting the first distortion parameter to the currently installed HUD, it is necessary to determine that the first serial number is inconsistent with the second serial number. The vehicle computer converts the first serial number and the second serial number into corresponding hash values ​​respectively by calling a hash function. If the hash value corresponding to the first serial number is not equal to the hash value corresponding to the second serial number, it is determined that the first serial number is inconsistent with the second serial number, and the first serial number stored in the vehicle computer is deleted, and the second serial number is stored in the vehicle computer, that is, the first serial number is updated to the second serial number. However, it should be clear that this statement is not intended to limit the method of determining the inconsistency between the first serial number and the second serial number.

[0086] Step 103: Transmit the first distortion parameter to the currently installed head-up display so that the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, wherein the first distortion parameter is a parameter of image distortion caused by the target windshield, and the second distortion parameter is a parameter of image distortion caused by the curved mirror of the currently installed head-up display.

[0087] The target HUD is replaced with the currently installed HUD, and the currently installed HUD only has the parameters of image distortion caused by the curved mirror of the currently installed HUD, but does not have the first distortion parameters, resulting in poor image distortion correction effect. The first distortion parameters stored in the vehicle computer need to be transmitted to the Electrically Erasable Programmable Read Only Memory (EEPROM) in the currently installed HUD, so that the currently installed HUD can perform distortion correction on the image data according to the first distortion parameters and the second distortion parameters. However, it should be clear that this statement is not intended to limit the first distortion parameters to be stored only in the EEPROM.

[0088] The present disclosure provides a method for correcting distortion parameters. In response to the vehicle being powered on, it is determined whether the first serial number of the target head-up display is consistent with the second serial number of the currently installed head-up display, wherein the first serial number is the serial number stored in the vehicle; if it is determined that the first serial number is inconsistent with the second serial number, the first serial number is updated to the second serial number; the first distortion parameter is transmitted to the currently installed head-up display, so that the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, wherein the first distortion parameter is the parameter of the image distortion caused by the target windshield, and the second distortion parameter is the parameter of the image distortion caused by the curved mirror of the currently installed head-up display. Compared with the related art, the embodiment of the present application transmits the first distortion parameter to the current head-up display during the replacement of the target head-up display, and the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, so that the image distortion correction effect remains unchanged after the replacement of the target head-up display.

[0089] In actual applications, the first distortion parameter and the third distortion parameter may be lost, so it is necessary to transmit the first distortion parameter and the third distortion parameter to the server for backup. Please continue to refer to Figure 2, before determining whether the first serial number of the target head-up display is consistent with the second serial number of the currently installed head-up display, the vehicle computer receives the third distortion parameter and the first serial number sent by the target HUD; after the target windshield is installed in the vehicle factory, the debugging personnel use professional camera equipment to collect the first distortion parameter, and transmit the first distortion parameter to the vehicle computer, and the vehicle computer obtains the vehicle identification code and the first distortion parameter of the vehicle; the vehicle computer binds the first serial number with the third distortion parameter to obtain the first binding data of the target head-up display; the vehicle computer binds the vehicle identification code with the first distortion parameter to obtain the second binding data of the vehicle; the vehicle computer stores the first binding data and the second binding data in the memory of the vehicle computer, and transmits the first binding data and the second binding data to the server. When the vehicle computer is replaced or the first binding data and the second binding data in the vehicle computer are lost, the vehicle computer sends a request message for obtaining the first binding data and the second binding data to the server, and the server transmits the first binding data and the second binding data to the vehicle computer according to the request message.

[0090] As a refinement of step 102, when updating the first serial number to the second serial number, it can be implemented in the following manners but not limited to: Figure 3 As shown, Figure 3 A flowchart of a method for updating a sequence number and distortion parameters provided in an embodiment of the present application includes:

[0091] Step 201: Obtain a second distortion parameter.

[0092] In order to ensure that the second distortion data is not lost, the second distortion data needs to be backed up, the vehicle computer is connected to the currently installed HUD, and the vehicle computer obtains the second distortion parameter stored in the currently installed HUD.

[0093] Step 202: Update the first serial number to the second serial number, and update the third distortion parameter to the second distortion parameter, respectively, wherein the third distortion parameter is a parameter of image distortion caused by the curved mirror of the target head-up display.

[0094] In order to avoid too many serial numbers and distortion parameters in the vehicle computer, resulting in insufficient memory of the vehicle computer, it is necessary to back up the serial numbers and distortion parameters by updating and replacing them, delete the first serial number and the third distortion parameter stored in the vehicle computer, and store the second serial number and the second distortion parameter in the vehicle computer. However, it should be clear that this statement is not intended to limit the update method of the serial number and distortion parameters.

[0095] In actual applications, the first distortion parameter and the third distortion parameter in the vehicle computer may be missing. For example, replacement of the vehicle computer may cause the first distortion parameter and the third distortion parameter to be missing, and the first distortion parameter and the third distortion parameter need to be re-acquired. Before determining whether the first serial number of the target head-up display is consistent with the second serial number of the currently installed head-up display, the vehicle computer determines whether the first distortion parameter and the third distortion parameter are missing; if the infotainment control determines that the first distortion parameter is missing, a request message for obtaining the second binding data is sent to the server based on the vehicle identification code to obtain the first distortion parameter in the second binding data; if the vehicle computer determines that the third distortion parameter is missing, a request message for obtaining the second distortion parameter is sent to the currently installed head-up display based on the second serial number to obtain the second distortion parameter.

[0096] In actual applications, the windshield of the vehicle may be damaged and need to be replaced. Since the distortion parameters of each windshield causing image distortion are different, it is necessary to manually delete the first distortion parameter in the target head-up display, the first distortion parameter in the vehicle computer, and the first distortion parameter in the server. After sending a request message for the second binding data to the server based on the vehicle identification code, if it is determined that the second binding data does not exist in the server, the first distortion parameter is updated to an uncalibrated parameter, and a prompt message that the first distortion parameter is unavailable is output, wherein the uncalibrated parameter does not include the distortion parameter; if it is determined that the first serial number is updated to the second serial number, the first serial number in the vehicle computer is updated to the second serial number, and the third distortion parameter is updated to the second distortion parameter, but the server does not have the updated first serial number and the updated third distortion parameter, it is necessary to transmit the updated first serial number and the updated third distortion parameter to the server for backup

[0097] Figure 4 A flowchart of a method for correcting distortion parameters provided in an embodiment of the present disclosure is provided.

[0098] like Figure 4 As shown, the method is applied to the HUD of a vehicle, and the method comprises the following steps:

[0099] Step 301: receiving a first distortion parameter sent by a vehicle computer, where the first distortion parameter is a parameter of image distortion caused by a target windshield.

[0100] In order to better understand the target HUD's distortion correction of the projected image, Figure 5 As shown, Figure 5A schematic diagram of a projected image reflection provided in an embodiment of the present application; the target HUD sends a projected image through an image generation unit (Picture Generation Unit, PGU), and the image is projected onto the windshield after reflection by a plane mirror and a curved mirror. Since the target HUD does not perform distortion correction on the image distortion caused by the windshield, the target HUD needs to receive the first distortion parameter sent by the vehicle computer and store it in the EEPROM so that the target HUD can perform distortion correction on the image distortion caused by the windshield.

[0101] Step 302: Acquire a third distortion parameter, where the third distortion parameter is a parameter of image distortion caused by the curved mirror of the target head-up display.

[0102] When the target HUD leaves the parts factory, a distortion correction will be performed. The distortion parameters of the image distortion caused by the curved mirror of the target HUD are collected using professional camera equipment, and the distortion parameters of the image distortion caused by the curved mirror of the target HUD are stored in the memory of the HUD.

[0103] Step 303: Call a preset algorithm to perform distortion correction on the image data according to the first distortion parameter and the third distortion parameter.

[0104] The target HUD calls a preset algorithm to perform distortion correction on the image data according to the first distortion parameter and the third distortion parameter. The preset algorithm is not a fixed algorithm and can be set according to actual conditions in actual applications. The embodiment of the present application does not limit this.

[0105] The present disclosure provides a method for correcting distortion parameters. In response to the vehicle being powered on, it is determined whether the first serial number of the target head-up display is consistent with the second serial number of the currently installed head-up display, wherein the first serial number is the serial number stored in the vehicle; if it is determined that the first serial number is inconsistent with the second serial number, the first serial number is updated to the second serial number; the first distortion parameter is transmitted to the currently installed head-up display, so that the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, wherein the first distortion parameter is the parameter of the image distortion caused by the target windshield, and the second distortion parameter is the parameter of the image distortion caused by the curved mirror of the currently installed head-up display. Compared with the related art, the embodiment of the present application transmits the first distortion parameter to the current head-up display during the replacement of the target head-up display, and the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, so that the image distortion correction effect remains unchanged after the replacement of the target head-up display.

[0106] As a refinement of step 303, when executing the calling preset algorithm and performing distortion correction on the image data according to the first distortion parameter and the third distortion parameter, it can be implemented in but not limited to the following manner: performing distortion correction on the image data according to the sum of the first distortion parameter and the third distortion parameter.

[0107] In summary, the embodiments of the present disclosure can achieve the following effects:

[0108] 1. In the embodiment of the present application, during the replacement of the target head-up display, the first distortion parameter is transmitted to the current head-up display, and the currently installed head-up display performs distortion correction on the image data according to the first distortion parameter and the second distortion parameter, so that the image distortion correction effect remains unchanged after the target head-up display is replaced.

[0109] 2. The embodiment of the present application solves the problem that the HUD distortion effect becomes worse due to the inability to reuse professional camera equipment to collect distortion parameters when the HUD is replaced after sales, by replacing the HUD after sales without affecting the distortion effect of the HUD.
