In some possible implementations, the method may be implemented by a processor invoking computer readable instructions stored in a memory, as shown in fig. 1, and may include the steps of:
s11: raw data is acquired.
The raw data includes information obtained by the navigation device and the ADAS system, such as vehicle sensing information, IMU (e.g., position coordinates of an inertial sensor), front camera target detection information, map, and the like, where the vehicle sensing information includes instrument information such as vehicle speed, electric quantity, navigation, and the like.
S12: and processing the original data to obtain target data, wherein the target data is used for vehicle-mounted head-up display and is related to preset parameters of the vehicle-mounted head-up display, and the image refresh rate represented by the target data is smaller than the resolution of human eyes.
The obtained original data is processed, for example, the original data is converted into image source data by a processing unit, so that target data is obtained and is presented to human eyes after passing through an optical amplifier. The target data is used for on-board head-up display and is related to preset parameters of the on-board head-up display, such as optical parameters of on-board head-up display equipment, and the refresh rate of an image represented by the target data is smaller than the resolution of human eyes, for example, the target data can be a piece of video data, the refresh rate of an image in the video data is smaller than the resolution of human eyes, namely, the delay of a display picture is lower than the visual delay of human eyes.
S13: outputting and displaying the target data.
The original data is processed to obtain target data, and an image represented by the target data is output through an output device and can be projected on a surface to be displayed, such as a windshield of a vehicle.
In this embodiment, the obtained original data is processed to obtain the target data, where the target data is used for on-vehicle head-up display and is related to preset parameters of the on-vehicle head-up display, and an image refresh rate represented by the target data is smaller than a resolution of human eyes, so that the target data is output and displayed, and ghost images generated when the on-vehicle head-up display device images are eliminated.
In some embodiments, the processing includes a first process and a second process, processing the raw data, including: performing first processing on the original data to obtain display data, wherein the image refresh rate represented by the display data is smaller than the resolution of human eyes; and performing second processing on the display data to obtain target data for vehicle-mounted head-up display.
The raw data is processed, wherein the processing includes a first process and a second process. The first processing may be to integrate the vehicle data into the display data, where the display data may be video data or image data, and the display data may be characterized by an image refresh rate smaller than the human eye resolution, for example, the refresh rate of an image in the video data as the display data is smaller than the human eye resolution, i.e., the delay of the display screen is lower than the visual delay of human eyes. And performing second processing on the display data, for example, performing preset processing on the image in the video data, so as to obtain target data for vehicle-mounted head-up display, and outputting the image in the video data through an output device so as to project the image on a surface to be displayed, for example, a windshield of a vehicle.
In some embodiments, first processing the raw data includes: constructing an environment where a target object is located in original data based on the original data so as to acquire three-dimensional data of the target object; and converting the three-dimensional data into two-dimensional data according to preset parameters of the vehicle-mounted head-up display, and carrying out matching adjustment with a picture of the vehicle-mounted head-up display to generate video data.
The method comprises the steps of constructing an environment where a target object is located in original data based on the original data, for example, integrating data such as ADAS perception identification data and vehicle sensors, modeling the environment where a current vehicle is located to obtain three-dimensional data of the target object, for example, calculating the size and the position of the target object, lane lines and the like in a three-dimensional space coordinate system, wherein the target object can be a vehicle, a pedestrian, an obstacle and the like. According to preset parameters of the vehicle head-up display, three-dimensional data are converted into two-dimensional data, for example, three-dimensional space of corresponding environments can be converted into two-dimensional space according to optical parameters of a HUD optical machine, positions of eyes and the like, further, matching adjustment is carried out on the three-dimensional space and a frame of the vehicle head-up display, video data are generated, for example, according to resolution and size of the optical machine frame in the vehicle head-up display device, display frames are adapted, and accordingly video data are generated, so that projection can be carried out better.
Further, in some embodiments, performing the first processing on the raw data further includes: preprocessing video data by using an algorithm to obtain processed video data serving as display data, wherein the resolution and the frame rate of the processed video data are respectively larger than a preset resolution and a preset frame rate.
The video data is preprocessed by an algorithm to obtain processed video data as display data, for example, the video is cut to be suitable resolution and frame rate by the algorithm, and further the processed video data is obtained as display data, wherein the resolution and frame rate of the processed video data are respectively larger than the preset resolution and the preset frame rate, for example, the visual absolute delay perceived by the human body perceptron function is about 20ms, the preset resolution and the preset frame rate can be determined based on the visual absolute delay perceived by the human body perceptron function, namely, the resolution of the processed video data is larger than the preset resolution, and the frame rate of the processed video data is larger than the preset frame rate. The resolution and frame rate of the processed video data are respectively greater than the preset resolution and the preset frame rate, which can be understood as that the picture delay is lower than the limit resolution of human eyes and the visual delay of a sensing organ by improving the display response speed and the refresh frame number of the HUD image source.
In some embodiments, performing a second process on the display data includes: and carrying out warp correction on each frame of video data corresponding to the display data, thereby obtaining target data.
And (3) warp correction is carried out on each frame of video data corresponding to the display data, namely, in order to better project and display, warp correction is carried out on each frame of image of the video data corresponding to the display data, and the obtained video data after the second processing can be used as target data for outputting and displaying.
For ease of understanding, the effect of the target data output display is illustrated in fig. 2, and fig. 2 is a schematic view of the display effect according to the embodiment of the present application. Before processing the original data, that is, before the image source does not increase the refresh rate of the image through an algorithm, the edge light of the amplified virtual image has very low luminous intensity due to the thickness of the windshield, and the primary light and the secondary light have dislocation, so that ghost images caused by obvious contrast difference are very obvious, as shown in fig. 2 (a). After the original data is processed, that is, after the refreshing efficiency of the image source is improved from the image source system through an algorithm, for example, after the picture delay of a virtual image is lower than 20ms, the picture overlapping speed of an adjacent image generating unit is lower than the resolution limit of human eyes, the edge contrast of the original single image is low, the edge contrast of the original single image is rapidly overlapped by the next image, the edge contrast is obviously improved, the whole icon seen by the human eyes has no obvious difference in contrast, and therefore, the existence of double images is not visually perceived, as shown in fig. 2 (b).
