[0023] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0024] In order to address the problems of poor interactive experience and insufficient visual appeal of the AVM floating window animation display technology used in the existing QNX system, this invention provides an AVM floating window animation display method for QNX.
[0025] This embodiment provides a method for displaying AVM floating window animation effects in QNX, such as... Figure 1 As shown, it includes the following steps: S10. Call the QNX Screen graphics system to create a floating window.
[0026] This step enables the creation of an AVM floating window for QNX on the QNX automotive-grade platform. Based on the subsequent animation implementation scheme, smooth animation effects of the AVM floating window are achieved on the QNX automotive-grade platform.
[0027] S20. Continuously monitor specific vehicle-mounted trigger signals, and trigger the floating window display upon detecting the floating window trigger signal.
[0028] In this step, the in-vehicle application continuously listens for specific trigger signals from the vehicle bus or system. These trigger signals correspond to driving scenarios that require displaying the vehicle's surroundings. When a floating window trigger signal is detected, the floating window is triggered to display.
[0029] This step specifically involves: continuously monitoring specific trigger signals in the vehicle; upon receiving any floating window trigger signal, triggering the floating window animation interface corresponding to the floating window trigger signal to start the floating window display; The floating window animation interface includes a floating window fade-in animation interface and a floating window fade-out animation interface; the floating window trigger signals include the R gear signal, the turn signal, and / or the radar warning signal.
[0030] The R gear signal is triggered when the vehicle is engaged in reverse gear; The turn signal is triggered when the left or right turn signal is activated; A radar warning signal is triggered when the vehicle's radar detects a nearby obstacle.
[0031] S30. Start the floating window animation loop, execute the preset animation variables, and make the floating window change from the first state animation effect to the second state.
[0032] The animation variables include the duration of the floating window animation, the animation update time interval, the cumulative value of transparency, and the value of position change.
[0033] In this step, the first state and the second state represent the state before and after the change in the floating window animation effect.
[0034] After the floating window animation loop starts, based on the floating window animation duration, animation update time interval, cumulative transparency value, and position change value, the floating window changes from the first state animation effect to the second state during the floating window animation duration.
[0035] This embodiment provides a method for displaying AVM floating window animation effects for QNX. It creates a floating window based on QNX's native Screen graphics interface. Upon detecting a floating window trigger signal, it executes a floating window animation loop using preset animation variables, thereby achieving a fade-in or fade-out animation effect. This method for displaying AVM floating window animation effects for QNX enables smooth AVM floating window animation effects on the QNX automotive-grade platform without relying on the Android framework, ensuring the high real-time performance and reliability of the automotive-grade system, and enhancing user interaction and visual appeal.
[0036] This embodiment, as a preferred embodiment, optimizes the specific implementation process of calling the QNX Screen graphics system to create a floating window.
[0037] In this embodiment, the QNX Screen graphics system is invoked to create a floating window, specifically including: Call the native API functions of the QNX Screen graphics system to create a floating window for displaying the AVM screen; Associating the floating window with the graphics rendering context prepares for subsequent rendering of the AVM video stream; Set the initial state of the floating window, which is the starting point for implementing the animation.
[0038] In this embodiment, the initial state includes the display size, initial transparency, and initial position.
[0039] The display size is set to the width and height of the floating window; the initial transparency of the floating window is set to 0, that is, completely transparent and invisible; the initial position of the floating window is set outside the visible area of the screen, that is, outside the left or right side of the screen, and the initial position of the floating window is used as the starting point of the animation.
[0040] This embodiment, as a preferred embodiment, optimizes the specific implementation process of the floating window changing from the first state animation effect to the second state.
[0041] In this embodiment, as Figure 2 As shown: The floating window animation loop is started, and preset animation variables are executed to change the floating window from the first state to the second state, specifically including: S301. Determine the first and second states of the floating window.
[0042] In this embodiment, the first state is the initial state, and the second state is the display state; Alternatively, the first state is the display state, and the second state is the initial state.
[0043] Therefore, this step determines the initial state and the display state.
[0044] The initial state includes the display size, initial transparency, and initial position; The display status includes display size, target transparency, and target position.
[0045] In this embodiment, the initial display size is the same as the display size in the current display state, that is, the display size before and after the floating window animation effect changes.
[0046] Set the target transparency of the floating window to 255, which is completely opaque.
[0047] S302. Start the floating window animation loop, so that the floating window updates the current transparency and current position once every animation update time interval based on the accumulated transparency value and the position change value.
[0048] In this step, the cumulative transparency value is calculated using the duration of the floating window animation, the animation update time interval, and the maximum transparency value; the position change is calculated using the duration of the floating window animation, the animation update time interval, and the total position displacement; and the total position displacement is calculated using the initial position and the target position of the floating window.
[0049] That is, the cumulative transparency value is how much the transparency needs to increase or decrease within each animation update interval in order to linearly increase from 0 to 255, or linearly decrease from 255 to 0, over the entire duration of the floating window animation.
[0050] The position change is the number of pixels the floating window needs to move within each animation update interval so that the floating window can move linearly from its initial position to its target position, or from its target position to its initial position, throughout the entire duration of the floating window animation.
[0051] This embodiment, as a preferred embodiment, optimizes the specific implementation process of updating the current transparency and current position of the floating window once every animation update time interval based on the cumulative transparency value and the position change value.
[0052] Specifically, when the first state is the initial state and the second state is the display state, the floating window updates its current transparency and position once every animation update interval based on the accumulated transparency value and the position change value, specifically including: The floating window increments the current transparency value and the current position value every time the animation updates.
[0053] When the first state is the display state and the second state is the initial state, the floating window updates its current transparency and position once every animation update interval based on the accumulated transparency value and the position change value. Specifically, this includes: The floating window performs an animation update every time interval, decreasing the current transparency by the accumulated transparency value and decreasing the current position by the position change value.
[0054] S303. When the current transparency of the floating window reaches the target transparency and the current position of the floating window coincides with the target position, terminate the animation loop and put the floating window into the second state.
[0055] That is, in this step, when the first state is the initial state and the second state is the display state, the floating window executes the current transparency increment value and the current position increment value once every animation update time interval. When the current transparency increases linearly from 0 to 255 during the entire floating window animation cycle, it becomes completely opaque, and the floating window moves linearly from the initial position to the target position. The loop ends, the floating window animation is completed, and it is clearly and stably displayed at the target position, realizing the floating window fade-in animation effect.
[0056] When the first state is the display state and the second state is the initial state, the floating window executes the current transparency increment value and the current position change value once every animation update time interval. When the current transparency linearly increases from 255 to 0 during the entire animation cycle of the floating window, it becomes completely transparent, and the floating window moves linearly from the target position to the initial position or moves out of the visible area of the screen. The loop ends, the floating window is no longer visible, and the floating window fade-out animation effect is realized. The animation is completed, so that the floating window can be safely hidden or destroyed.
[0057] In some optional embodiments, the present invention also discloses an AVM floating window animation display system for QNX, which uses any one of the above-described AVM floating window animation display methods for QNX to achieve a floating window fade-in and fade-out animation display.

[0061] The floating window trigger module 200 is used to continuously monitor specific trigger signals in the vehicle. When the floating window trigger signal is detected, the floating window is triggered to display.
[0062] In this embodiment, the floating window trigger module 200 continuously monitors the specific trigger signal of the vehicle. When the floating window trigger signal is detected, the specific implementation process of triggering the floating window display is described in step S20 of the above-mentioned AVM floating window animation display method for QNX. This embodiment will not repeat the description.
[0063] The floating window animation execution module 300 is used to start the floating window animation loop, execute preset animation variables, and make the floating window change from the first state animation effect to the second state.
