Description

Technical Field

[0001] The present application relates to the technical field of head-up display, and in particular to a head-up display method and device. Background Art

[0002] AR-HUD (Augmented Reality-Head Up Display) is an augmented reality head-up display technology that reasonably superimposes navigation instructions, lane departure warnings, adaptive cruise control and other information in the driver's field of vision, integrating the HUD virtual image with the real road scene, which not only ensures driving safety, but also enhances the fun and comfort of driving. However, in the process of using AR technology, more computing power and hardware resources are required in software operation.

[0003] In the prior art, specific modules or fixed computing units are used to process specific tasks. Using a single fixed computing unit to process a specific task often consumes the computing power of a certain computing unit and causes anomalies in scenarios with high resource consumption. Even if hardware resources and computing power are sufficient, a computing unit may be overloaded while other computing units may be underloaded, which is a waste of hardware resources. Summary of the invention

[0004] The embodiments of the present application provide a head-up display method and device, which can determine a computing unit that performs a head-up display task from multiple computing units through computing power matching, thereby avoiding a situation where one computing unit among the multiple computing units is overloaded while other computing units are underloaded.

[0005] In a first aspect, an embodiment of the present application provides a head-up display method, the method comprising:

[0006] Get the heads-up display task;

[0007] The head-up display task is processed by a first computing unit among multiple computing units, and the first computing unit is determined from multiple computing units based on a predicted computing power consumption value when each computing unit in the multiple computing units executes the head-up display task and a first remaining computing power value of each computing unit.

[0008] It can be seen that in the embodiment of the present application, the first computing unit is determined from multiple computing units according to the predicted computing power consumption value when each computing unit performs the head-up display task and the first remaining computing power value of each computing unit, and the head-up display task is processed by the first computing unit. In this way, it is possible to avoid the situation where one computing unit among the multiple computing units is overloaded while other computing units are underloaded, thereby giving full play to the hardware resources.

[0009] In a feasible embodiment, the plurality of computing units include at least two different types of computing units. Selecting the first computing unit from the plurality of computing units means selecting the first computing unit from all computing units available in the head-up display device, not just a single type of computing unit, so that the hardware resources of the head-up display device can be fully utilized.

[0010] Furthermore, in a feasible embodiment, the multiple computing units are of different types.

[0011] In a feasible embodiment, the predicted value of computing power consumption when each computing unit performs a head-up display task is determined according to a mapping table of computing power consumption predictions between the task type of the head-up display task and multiple computing units. This facilitates determining the predicted value of computing power consumption when each computing unit performs a head-up display task.

[0012] In a feasible embodiment, the method also includes: determining at least one second computing unit based on the predicted computing power consumption value of the head-up display task and the remaining computing power values ​​corresponding to multiple computing units respectively; determining the first computing unit from at least one second computing unit; wherein the target difference between the remaining computing power value of the second computing unit and the predicted computing power consumption value when the second computing unit performs the head-up display task is greater than a first preset threshold.

[0013] By determining the first computing unit using the method shown in the embodiment of the present application, it is possible to avoid overloading a single computing unit, thereby improving the operating performance of the head-up display device.

[0014] In a feasible embodiment, determining the first computing unit from at least one second computing unit includes: if there is one second computing unit, determining the second computing unit as the first computing unit; if there are multiple second computing units, determining the first computing unit from multiple second computing units according to a selection strategy.

[0015] In an embodiment of the present application, if it is determined that the target difference between the predicted value of the computing power consumption of the second computing unit to perform the head-up display task and the remaining computing power value of the second computing unit is greater than a preset threshold, the second computing unit is determined to be the first computing unit to perform the head-up display task. This can avoid excessive load on a single computing unit, thereby improving the operating performance of the head-up display device.

[0016] In a feasible embodiment, the first computing unit is a computing unit pre-set to perform the head-up display task among the plurality of second computing units; or the first computing unit is a computing unit with the largest target difference among the plurality of second computing units. In this way, the hardware resources of the head-up display device can be fully utilized.

[0017] In a feasible embodiment, when the head-up display task is multiple tasks, the method further includes: determining the first calculation unit from multiple calculation units according to the matching orders corresponding to the multiple head-up display tasks respectively, and the matching order is determined according to the priority of the task categories corresponding to the multiple head-up display tasks respectively.

[0018] In the embodiment of the present application, when there are multiple head-up display tasks, the order in which each head-up display task matches the first computing unit from multiple computing units is determined by the priorities corresponding to the multiple head-up display tasks. This not only allows the head-up display tasks with high priorities to be processed in advance, but also avoids the problem of a single computing unit being overloaded when multiple head-up display tasks simultaneously match the first computing unit from multiple computing units.

[0019] In a feasible embodiment, the corresponding first computing units are matched from the multiple computing units according to the matching orders corresponding to the multiple head-up display tasks, including: for the i-th head-up display task among the multiple head-up display tasks, the second remaining computing power value of each computing unit is obtained, the second remaining computing power value of each computing unit is determined based on the first remaining computing power value and the computing power required for each computing unit to process the first i-1 head-up display tasks among the multiple head-up display tasks, and the matching order of the i-th head-up display task is less than the matching order of the first i-1 head-up display tasks; the first computing unit is determined from the multiple computing units according to the predicted computing power consumption value when each computing unit executes the head-up display task and the second remaining computing power value of each computing unit.

[0020] In the embodiment of the present application, the aforementioned method is used to solve the problem that the remaining computing power values ​​of multiple computing units cannot be accurately determined when the computing power of multiple head-up display tasks are simultaneously matched.

[0021] In a feasible embodiment, when the head-up display task consists of multiple tasks, the method further includes: determining the first computing unit of the head-up display task in the target task set based on a comparison relationship between the first computing power value and the remaining computing power value of the third computing unit; wherein the target task set is one of at least one task set, and at least one task set is obtained by dividing multiple head-up display tasks, and the computing units with the highest priority for executing the head-up display tasks belonging to the same task set are of the same type, the first computing power value is the sum of the predicted computing power consumption values ​​corresponding to the third computing unit executing the head-up display tasks in the target task set, and the third computing unit is the computing unit with the highest priority for executing the head-up display tasks in the target task set among the multiple computing units.

[0022] In the embodiment of the present application, multiple head-up display tasks are divided according to the different priorities of the multiple computing units corresponding to the multiple head-up display tasks to determine at least one task set, and the head-up display tasks in each task set are matched with the computing units corresponding to the task set. In this way, the time for computing power matching of multiple head-up display tasks can be reduced, thereby improving the efficiency of head-up display task processing.

[0023] In a feasible embodiment, the first computing unit of the head-up display task in the target task set is determined based on the comparison relationship between the first computing power value and the remaining computing power value of the third computing unit, including: when the first computing power value is less than the remaining computing power value of the third computing unit, determining the third computing unit as the first computing unit to execute the head-up display task in the target task set; when the first computing power value is not less than the remaining computing power value of the third computing unit, eliminating at least one target head-up display task from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, and the second computing power value is the sum of the computing power consumption prediction values ​​corresponding to the head-up display tasks in the target task set after eliminating at least one target head-up display task from the target task set.

[0024] By determining the first computing unit corresponding to the head-up display task in the target task set using the method shown in the embodiment of the present application, the time for computing power matching of multiple head-up display tasks can be reduced, thereby improving the efficiency of head-up display task processing.

[0025] In a feasible embodiment, at least one target head-up display task is eliminated from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, including: randomly eliminating a target number of head-up display tasks from the head-up display tasks in the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, and the difference between the remaining computing power value of the third computing unit and the second computing power value is less than a second preset threshold; wherein the target number is determined based on the difference between the first computing power value and the remaining computing power value of the third computing unit and the average computing power value, and the average computing power value is determined based on the first computing power value and the number of head-up display tasks in the target task set.

[0026] In the embodiment of the present application, the above method is adopted to randomly remove the target number of head-up display tasks from the head-up display tasks in the target task set, so that the second computing power value is greater than the remaining computing power value of the third computing unit, and the difference between the remaining computing power value of the third computing unit and the second computing power value is less than the second preset threshold value. This can not only reduce the time for the head-up display task to perform computing power matching, but also improve the efficiency of the head-up display task processing.

[0043] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] See also Figure 1 , Figure 1 A schematic diagram of the structure of a head-up display device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the head-up display device 100 includes a data processing unit 101 and a plurality of computing units 102 .

[0045] Among them, the data processing unit 101 can be one of the multiple computing units 102, but the data processing unit 101 does not participate in the processing of the head-up display task. The multiple computing units 102 may include at least two types of computing units. In addition, the types of the multiple computing units 102 may also be different. The types of the computing units include but are not limited to central processing units (CPU), graphics processing units (GPU), micro controller units (MCU) or other special computing units, such as network processing units (NPU), video processing units (VPU), digital signal processing chips (DSP), field programmable gate array chips (FPGA).

[0046] In addition, the data processing unit 101 and the plurality of computing units 102 together constitute a controller, which may also be a domain controller independent of the head-up display device, in which some of the plurality of computing units 102 may constitute a plurality of system-on-chips (SoCs), and each SoC includes a plurality of computing units 102 of different types, such as CPUs and GPUs. The domain controller is used to drive the head-up display device, and a head-up display task in the head-up display device may be processed by a plurality of SoCs or other computing units in the domain controller.

[0047] The head-up display device 100 receives head-up display related data and head-up display tasks from the device bus, wherein the bus may be a CAN bus or an ETH bus in a car, and the head-up display related data may be ADAS data, DMS data, navigation data, etc. in the car. The head-up display tasks include data processing tasks, image processing tasks, rendering tasks, display tasks, etc. When processing some head-up display tasks, corresponding algorithms need to be called, such as image quality optimization algorithms, AR fusion algorithms, and distortion correction algorithms.

[0048] In a specific application, after obtaining a head-up display task, the data processing unit 101 in the head-up display device 100 determines a corresponding first computing unit from the multiple computing units 102 to process the head-up display task based on the predicted computing power consumption of the multiple computing units 102 for executing the head-up display task and the remaining computing power values ​​of the multiple computing units 102. This can avoid the situation where one of the multiple computing units 102 is overloaded while other computing units are underloaded, thereby giving full play to the hardware resources of the head-up display device 100.

[0049] Based on this, an embodiment of the present application provides a head-up display method, and the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0050] See also Figure 2 , Figure 2 A schematic diagram of a head-up display method provided in an embodiment of the present application, wherein the head-up display method is applied to Figure 1 The data processing unit 101 shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0051] Step 201, obtaining a head-up display task.

[0052] Among them, the head-up display task may include rendering tasks, image processing tasks, display tasks, etc. Refers to the related tasks that need to be completed before the head-up display related information is projected.

[0053] Step 202 : Processing a head-up display task by a first computing unit among a plurality of computing units.

[0054] Among them, the first computing unit is determined from multiple computing units based on the predicted computing power consumption value of each computing unit when performing the head-up display task and the first remaining computing power value of each computing unit. And the predicted computing power consumption value of each computing unit when performing the head-up display task shown in this embodiment can be determined according to the task type of the head-up display task and the computing power consumption prediction mapping table between multiple computing units. This makes it easy to determine the predicted computing power consumption value of each computing unit when performing the head-up display task.

[0055] For example, please refer to Table 1, which is a computing power consumption prediction mapping table. The computing power consumption prediction value of each computing unit when executing the head-up display task can be obtained based on experience or after deep learning based on historical computing power consumption values.

[0056] Table 1

[0057] Heads-up display tasks The first type of computing unit computing power consumption The second type of computing unit computing power consumption …… Heads-up display task 1 1.5K DMIPS 1.2G Flops …… Heads-up display task 2 2.5K DMIPS 2.2G Flops …… Heads-up display task 3 5.6K DMIPS 5.2G Flops …… …… …… …… ……

[0058] According to the predicted value of computing power consumption when each computing unit executes the head-up display task and the remaining computing power value of each computing unit, the computing unit that is easiest to process the head-up display task among multiple computing units can be determined, thereby improving the operating performance of the entire head-up display device.

[0059] The multiple computing units include at least two different types of computing units, and different types of computing units have different computing methods for the same head-up display task. For example, when the GPU and the CPU process and calculate the same head-up display task, the GPU's computing method is to split the required operations into small, simple operations, and then process them in parallel; while the CPU directly processes the required operations. In other words, the number of computing units of a single type in the multiple computing units may be multiple.

[0060] In addition, the types of the multiple computing units may be different. Selecting the first computing unit from the multiple computing units means selecting a computing unit from multiple different types of computing units as the first computing unit. For example, selecting a computing unit from a CPU and a GPU as the first computing unit.

[0061] In a feasible embodiment, the method also includes: determining at least one second computing unit based on the predicted computing power consumption value of the head-up display task and the remaining computing power values ​​corresponding to multiple computing units respectively; determining the first computing unit from at least one second computing unit; wherein the target difference between the remaining computing power value of the second computing unit and the predicted computing power consumption value when the second computing unit performs the head-up display task is greater than a first preset threshold.

[0062] Among them, in order to give full play to hardware resources and balance the load of hardware resources, this embodiment determines the first computing unit from multiple computing units through the predicted value of computing power consumption when each computing unit executes the head-up display task and the first remaining computing power value of each computing unit. Specifically, the target difference between the predicted value of computing power consumption when the second computing unit executes the head-up display task and the remaining computing power value of the second computing unit in each computing unit is determined. If the target difference is greater than the first preset threshold, it can be determined that the second computing unit is relatively idle, and processing the head-up display task by the second computing unit will not cause the second computing unit to be overloaded, and the first preset threshold can be determined separately according to different computing units. Determining the first computing unit by the method shown in the embodiment of the present application can avoid overloading a single computing unit, thereby improving the operating performance of the head-up display device.

[0063] Furthermore, in a feasible embodiment, determining the first computing unit from at least one second computing unit includes: if there is one second computing unit, determining the second computing unit as the first computing unit; if there are multiple second computing units, determining the first computing unit from multiple second computing units according to a selection strategy.

[0064] Among them, a second computing unit whose target difference is greater than a first preset threshold is selected from multiple computing units. There may be multiple second computing units. At this time, it is necessary to select one second computing unit from the multiple second computing units as the first computing unit according to the selection strategy.

[0065] In an embodiment of the present application, if it is determined that the target difference between the predicted value of the computing power consumption of the second computing unit to perform the head-up display task and the remaining computing power value of the second computing unit is greater than a preset threshold, the second computing unit is determined to be the first computing unit to perform the head-up display task. This can avoid excessive load on a single computing unit, thereby improving the operating performance of the head-up display device.

[0066] In a feasible embodiment, the first computing unit is a computing unit pre-set to perform the head-up display task among the plurality of second computing units; or, the first computing unit is a computing unit with the largest target difference among the plurality of second computing units.

[0067] Each of the plurality of computing units has a pre-set category of a head-up display task for execution, and the pre-set computing units for executing the head-up display task are all computing units that are most suitable for the head-up display task category.

[0068] In addition, if there is no computing unit pre-set to perform the head-up display task among the multiple second computing units, the computing unit with the highest priority for performing the head-up display task among the multiple second computing units can be determined as the first computing unit. The priority of performing the head-up display task among the multiple computing units can be determined by the historical number of times the head-up display task of this type is performed among the multiple computing units. The more historical numbers of times the target computing unit among the multiple computing units performs the head-up display task of this type, the higher the priority of the target computing unit for performing the head-up display task. The reason why the first computing unit is determined according to the priority of performing the head-up display task is that after the processor processes a task, the residual information of the task will be retained in the state of the processor (i.e., the processor cache). If the same type of task is handed over to the processor for processing next time, the processor will process the task more efficiently. Therefore, determining the computing unit with the highest priority for performing the head-up display task from the multiple second computing units as the first computing unit can make the processing of the head-up display task more efficient.

[0069] In addition, the priority of executing the head-up display task among multiple computing units can also be determined according to the processing characteristics of each computing unit among the multiple computing units. For example, the GPU's ability to process image data is stronger than the CPU's ability to process image data. Therefore, for image data processing tasks, the GPU's priority is higher than the CPU.

[0070] In addition, the calculation unit with the largest corresponding target difference in the second calculation unit may be selected as the first calculation unit, so that the hardware resources of the head-up display device can be fully utilized.

[0071] In a feasible embodiment, when the head-up display task is multiple tasks, the method further includes: determining the first calculation unit from multiple calculation units according to the matching orders corresponding to the multiple head-up display tasks respectively, and the matching order is determined according to the priority of the task categories corresponding to the multiple head-up display tasks respectively.

[0072] Among them, when the head-up display task consists of multiple tasks, since the first computing unit selected from multiple computing units to execute the head-up display task is determined based on the predicted computing power consumption value when each computing unit executes the head-up display task and the first remaining computing power value of each computing unit, if the first computing units corresponding to the multiple head-up display tasks are selected from multiple computing units at the same time, there may be multiple head-up display tasks that select the same computing unit at the same time, and the remaining computing power value of the computing unit is less than the sum of the predicted computing power consumption values ​​corresponding to the multiple head-up display tasks. Therefore, this embodiment determines the matching order corresponding to the multiple head-up display tasks respectively by the priorities corresponding to the multiple head-up display tasks respectively. Avoid the above situation caused by the simultaneous computing power matching of multiple head-up display tasks.

[0073] The priorities corresponding to the multiple head-up display tasks are determined according to the priorities of the task categories corresponding to the multiple head-up display tasks, wherein the priorities of the task categories corresponding to the head-up display tasks can be determined according to the size of the average computing power consumption prediction value of the head-up display tasks under the task category, that is, if the average computing power consumption prediction value of the head-up display tasks under the first task category is larger, the priority corresponding to the first task category is higher. In addition, the priorities corresponding to the task categories can also be set by the user.

[0074] This embodiment can classify the two conditions of the priority of the character categories corresponding to the multiple head-up display tasks and the size of the predicted computing power consumption corresponding to the multiple head-up display tasks into primary and secondary categories. Exemplarily, when the priority of the character categories corresponding to the multiple head-up display tasks is the main condition for evaluating the priority of the multiple head-up display tasks, after the first sorting according to the priority of the task categories corresponding to the multiple head-up display tasks, there will be multiple head-up display tasks of the same task category corresponding to the same priority. At this time, the priority between the multiple head-up display tasks of the same task category is determined according to the predicted computing power consumption value of each head-up display task in the multiple head-up display tasks of the same task category. At this time, the larger the predicted computing power consumption value of the target head-up display task among the multiple head-up display tasks of the same task category, the higher the priority of the target head-up display task.

[0075] In the embodiment of the present application, when there are multiple head-up display tasks, the order in which each head-up display task matches the first computing unit from multiple computing units is determined by the priorities corresponding to the multiple head-up display tasks. This not only allows the head-up display tasks with high priorities to be processed in advance, but also avoids the problem of a single computing unit being overloaded when multiple head-up display tasks simultaneously match the first computing unit from multiple computing units.

[0076] In a feasible embodiment, the corresponding first computing units are matched from the multiple computing units according to the matching orders corresponding to the multiple head-up display tasks, including: for the i-th head-up display task among the multiple head-up display tasks, the second remaining computing power value of each computing unit is obtained, the second remaining computing power value of each computing unit is determined based on the first remaining computing power value and the computing power required for each computing unit to process the first i-1 head-up display tasks among the multiple head-up display tasks, and the matching order of the i-th head-up display task is less than the matching order of the first i-1 head-up display tasks; the first computing unit is determined from the multiple computing units according to the predicted computing power consumption value when each computing unit executes the head-up display task and the second remaining computing power value of each computing unit.

[0077] Among them, when multiple head-up display tasks match the first computing unit from multiple computing units according to their corresponding matching order, if the first head-up display task successfully matches the first computing unit, then when the subsequent head-up display tasks are matched, the remaining computing power value of the first computing unit needs to be the initial remaining computing power value minus the predicted computing power consumption value of the first computing unit when executing the first head-up display task. This can solve the problem that the remaining computing power values ​​of multiple computing units cannot be accurately determined when multiple head-up display tasks are performing computing power matching at the same time.

[0078] In addition, in a feasible embodiment, when the head-up display task consists of multiple tasks, the method further includes: determining a first computing unit of the head-up display task in the target task set based on a comparison relationship between the first computing power value and the remaining computing power value of the third computing unit; wherein the target task set is one of at least one task set, and at least one task set is obtained by dividing multiple head-up display tasks, and the computing units with the highest priority for executing the head-up display tasks belonging to the same task set are of the same type, the first computing power value is the sum of the predicted computing power consumption values ​​corresponding to the third computing unit executing the head-up display tasks in the target task set, and the third computing unit is the computing unit with the highest priority for executing the head-up display tasks in the target task set among the multiple computing units.

[0079] Furthermore, in a feasible embodiment, the first computing unit of the head-up display task in the target task set is determined based on the comparison relationship between the first computing power value and the remaining computing power value of the third computing unit, including: when the first computing power value is less than the remaining computing power value of the third computing unit, determining the third computing unit as the first computing unit to execute the head-up display task in the target task set; when the first computing power value is not less than the remaining computing power value of the third computing unit, eliminating at least one target head-up display task from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, and the second computing power value is the sum of the computing power consumption prediction values ​​corresponding to the head-up display tasks in the target task set after eliminating at least one target head-up display task from the target task set.

[0080] Among them, when the number of head-up display tasks is too large, it will waste too much time to match the first computing unit from multiple computing units according to the matching order corresponding to each head-up display task in the multiple head-up display tasks. Therefore, this embodiment divides the multiple head-up display tasks according to the different priorities of the multiple computing units corresponding to the multiple head-up display tasks to obtain at least one task set, wherein the computing units with the highest priority for executing the head-up display tasks belonging to the same task set are of the same type. Therefore, each task set corresponds to a different computing unit, and at this time, the head-up display tasks in each task set can be matched with the computing units corresponding to the task set at the same time.

[0081] For example, if the multiple head-up display tasks include task A, task B, task C and task D, where the computing unit with the highest priority for executing tasks A and task C is the GPU, and the computing unit with the highest priority for executing tasks B and task D is the CPU, then the multiple head-up display tasks are divided to obtain two task sets, where the first task set includes tasks A and task C, and the second task set includes tasks B and task D.

[0082] Specifically, for the target task set in at least one task set, it is necessary to determine the sum of the predicted computing power consumption values ​​corresponding to the head-up display tasks in the target task set executed by the third computing unit corresponding to the target task set, and determine whether to use the third computing unit as the first computing unit to execute the head-up display tasks in the target task set based on the size relationship between the sum of the predicted computing power consumption values ​​and the remaining computing power value of the third computing unit. If the sum of the predicted computing power consumption values ​​is less than the remaining computing power value of the third computing unit, the third computing unit can be used as the first computing unit to execute the head-up display tasks in the target task set. If the sum of the predicted computing power consumption values ​​is not less than the remaining computing power value of the third computing unit, it is necessary to consider eliminating some of the head-up display tasks in the target task set so that the sum of the predicted computing power consumption values ​​corresponding to the eliminated target task set is less than the remaining computing power value of the third computing unit.

[0083] As for the eliminated head-up display tasks, computing power matching can be directly performed through other computing units that do not correspond to at least one task set to determine the first computing unit used to execute the eliminated head-up display tasks; the remaining computing power of the third computing unit can also be detected in real time. When there are completed tasks in the target task set, the remaining computing power value of the third computing unit will increase. When the remaining computing power of the third computing unit can meet the requirements of executing the eliminated head-up display tasks, the eliminated head-up display tasks are processed by the third computing unit.

[0084] In the embodiment of the present application, multiple head-up display tasks are divided according to the different priorities of the multiple computing units corresponding to the multiple head-up display tasks to determine at least one task set, and the head-up display tasks in each task set are matched with the computing units corresponding to the task set. In this way, the time for computing power matching of multiple head-up display tasks can be reduced, thereby improving the efficiency of head-up display task processing.

[0085] Specifically, in a feasible embodiment, at least one target head-up display task is eliminated from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, including: randomly eliminating a target number of head-up display tasks from the head-up display tasks in the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, and the difference between the remaining computing power value of the third computing unit and the second computing power value is less than a second preset threshold; wherein the target number is determined based on the difference between the first computing power value and the remaining computing power value of the third computing unit and the average computing power value, and the average computing power value is determined based on the first computing power value and the number of head-up display tasks in the target task set.

[0086] Among them, if it is necessary to propose at least one target head-up display task from the target task set, it is necessary to first determine the number of target head-up display tasks and eliminate them according to the corresponding data. If the number of target head-up display tasks is not determined and then eliminated, a lot of trial and error time will be wasted. In this embodiment, the average computing power value is determined according to the first computing power value and the number of head-up display tasks in the target task set, and the target number of target head-up display tasks is determined according to the difference between the first computing power value and the remaining computing power value of the third computing unit and the average computing power value. After the target number of target head-up display tasks is determined, the target number of head-up display tasks are randomly eliminated from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit, and the difference between the remaining computing power value of the third computing unit and the second computing power value is less than the second preset threshold.

[0087] Exemplarily, if the head-up display tasks in the target task set include task 1, task 2, task 3 and task 4, the predicted computing power consumption values ​​corresponding to the execution of the head-up display tasks by the third computing unit are task 1 (30), task 2 (40), task 3 (36) and task 4 (30), respectively. If the remaining computing power value of the third computing unit is 80 at this time, then the remaining computing power value of the third computing unit 80 is less than the first computing power value 136. At this time, at least one head-up display task needs to be removed from the target task set so that the second computing power value is greater than the remaining computing power value of the third computing unit. If the removal is performed directly, it is necessary to continuously try and error, that is, first continuously remove one of the head-up display tasks. If it is found that removing one head-up display task cannot achieve a second computing power value greater than the remaining computing power value of the third computing unit, then remove two of the head-up display tasks. However, after this embodiment determines that the target number is 2 through the difference 56 between the first computing power value 136 and the remaining computing power value 80 of the third computing unit and the average computing power value 36, it can be directly determined that two head-up display tasks need to be removed from the target task set so that the second computing power value is less than the remaining computing power value of the third computing unit.

[0088] In the embodiment of the present application, the above method is adopted to randomly remove the target number of head-up display tasks from the head-up display tasks in the target task set, so that the second computing power value is less than the remaining computing power value of the third computing unit, and the difference between the remaining computing power value of the third computing unit and the second computing power value is less than the second preset threshold value. This can not only reduce the time for the head-up display task to perform computing power matching, but also improve the efficiency of the head-up display task processing.

[0089] Among them, after the first computing unit is determined from multiple computing units, the head-up display task is processed by the first computing unit, which can avoid excessive load on a single computing unit, thereby improving the operating efficiency of the head-up display device. The head-up display task is processed by the first computing unit, often by calling the driver of the first computing unit or by calling the API provided by the first computing unit to receive the head-up display task. Exemplarily, in the drawing and rendering task, calling the OpenGL interface can select the computing unit GPU to complete the drawing and rendering task, calling the GDI graphics interface can select the computing unit CPU to complete the drawing and rendering task, and calling the driver of the graphics dedicated circuit can select the computing unit IPU to complete the drawing and rendering task.

[0090] For example, see Figure 3 , Figure 3 A schematic diagram of a head-up display task execution process provided in an embodiment of the present application is as follows: Figure 3 As shown, first start the bus data reading task, determine the computing unit that successfully matches the bus data reading task among multiple computing units according to the computing power matching, and execute the bus data reading task according to the successfully matched computing unit; then start the rendering task, determine the computing unit that successfully matches the rendering task among multiple computing units according to the computing power matching, and execute the rendering task according to the successfully matched computing unit; then start the image processing task, at this time, you can first load the image processing algorithm corresponding to the image processing task, determine the computing unit that successfully matches the image processing algorithm among multiple computing units according to the computing power matching, and execute the image processing algorithm according to the successfully matched computing unit. In addition, the head-up display task also includes many other tasks, such as display tasks, etc., which will not be elaborated this time.

[0091] It can be seen that in the embodiment of the present application, the first computing unit is determined from multiple computing units according to the predicted computing power consumption value when each computing unit performs the head-up display task and the first remaining computing power value of each computing unit, and the head-up display task is processed by the first computing unit. In this way, it is possible to avoid the situation where one computing unit among the multiple computing units is overloaded while other computing units are underloaded, thereby giving full play to the hardware resources.

[0092] In another feasible embodiment, the plurality of computing units include a plurality of computing units of different types, and the head-up display method includes:

[0093] Step 301, obtaining a heads-up display task.

[0094] Step 302, processing the head-up display task by a first computing unit among multiple types of computing units, where the first computing unit is determined from multiple types of computing units based on a predicted value of computing power consumption when each computing unit performs the head-up display task and a first remaining computing power value of each computing unit.

[0095] Among them, for a first computing unit among multiple types of computing units, the first computing unit may include multiple ones, and the first remaining computing power value of the first computing unit is the sum of the remaining computing power values ​​of the multiple first computing units.

[0096] Specifically, in the case where there are multiple first computing units, the head-up display task is processed by a first computing unit among multiple types of computing units, including: processing the head-up display task by multiple first computing units at the same time, or processing the head-up display task by a target computing unit, the target computing unit is one of the multiple first computing units, and the difference between the remaining computing power value of the target computing unit and the predicted computing power consumption value when the target computing unit performs the head-up display task is greater than a first preset threshold.

[0097] It can be understood that determining the first computing unit from multiple types of computing units can be performed according to the method for determining the first computing unit from multiple computing units shown in the above embodiment.

[0098] In this embodiment, a suitable computing unit is selected according to the computing capabilities of multiple types of computing units, which can avoid the situation where one computing unit among the multiple computing units is overloaded while other computing units are underloaded, thereby fully utilizing hardware resources.

[0110] In a feasible embodiment, a determination unit 403 is used to determine the first computing unit of the head-up display task in the target task set based on a comparison relationship between the first computing power value and the remaining computing power value of the third computing unit, including: when the first computing power value is less than the remaining computing power value of the third computing unit, determining the third computing unit as the first computing unit to execute the head-up display task in the target task set; a processing unit 402 is used to eliminate at least one target head-up display task from the target task set when the first computing power value is not less than the remaining computing power value of the third computing unit, so that the second computing power value is less than the remaining computing power value of the third computing unit, and the second computing power value is the sum of the computing power consumption prediction values ​​corresponding to the head-up display tasks in the target task set after eliminating at least one target head-up display task in the target task set.
