Detailed Description
The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, the reverse display method provided in the embodiment of the present invention may be applied to displaying a reverse image, and the reverse display method may be executed by the reverse display device provided in the embodiment of the present invention, and the reverse display device may be implemented in a software and/or hardware manner, and in a specific application, the reverse display device may be a car machine. In this embodiment, taking an execution main body of the reverse display method as an example, the reverse display method includes the following steps:
Step S101: when a reverse gear signal is monitored, acquiring recorded target image information of the vehicle when the vehicle is reversed last time; the target image is at least one frame image closest to the current time;
here, the vehicle may be a motor vehicle such as an automobile or a non-motor vehicle such as an electric vehicle, and in the present embodiment, the vehicle is taken as an example of an automobile. In practical application, the car machine may monitor system data of the vehicle in real time to detect whether a reverse gear signal is monitored, for example, the car machine reads OBD data of the vehicle in real time to detect whether the OBD data contains the reverse gear signal. It should be noted that, the implementation process of monitoring the reverse gear signal by the vehicle in this embodiment may be the same as the implementation process of monitoring the reverse gear signal by the vehicle in the prior art.
It is understood that the vehicle machine may record image information of the vehicle during each reversing process, and the image information may include the image itself, corresponding acquisition time, acquisition location, and vehicle surrounding environment information. The image refers to an image behind the vehicle during reversing, and generally refers to an image including contents such as scenes in a certain range behind the vehicle, where the range is generally limited by factors such as hardware parameters, installation positions, and number of rear cameras (also referred to as reversing cameras) of the vehicle. The acquisition time refers to the time corresponding to the image acquired, and may be the time when the rear camera of the vehicle acquires the image, or the time when the vehicle acquires the image acquired by the rear camera of the vehicle. The acquisition position refers to the position of the vehicle when the image is acquired, and when the vehicle machine acquires an image acquired by a rear camera of the vehicle, the vehicle machine can simultaneously read the position of the vehicle through a positioning device of the vehicle, such as a global positioning navigation system, a Beidou satellite navigation system and the like, and the position is used as the acquisition position corresponding to the image. The vehicle surrounding environment information refers to information such as light brightness and weather conditions of the environment where the vehicle is located when the image is collected, and can be acquired through collection devices such as a light sensor, a rainwater sensor and a temperature sensor which are installed on the vehicle.
It can be understood that when the image information of the last vehicle reversing is recorded in the vehicle machine, the vehicle machine can determine that the vehicle needs to perform the reversing operation when the vehicle machine currently monitors a reverse signal, and at this time, at least one frame of image information closest to the current time is obtained from the recorded image information of the last vehicle reversing. Here, the target image may be one frame image closest to the current time, or may be two or more frames images closest to the current time. In this embodiment, the target image is taken as an example of a frame image closest to the current time.
Step S102: and when the target image meets the preset condition according to the target image information, displaying the target image firstly, and then displaying the image behind the vehicle, which is acquired by a rear camera of the vehicle.
Specifically, the vehicle machine detects whether the target image meets a preset condition according to the target image information obtained in step S101 when the vehicle is backed last time, and if the target image meets the preset condition, the vehicle machine displays the target image first, and then displays an image behind the vehicle, which is acquired by a rear camera of the vehicle; and if the target image does not meet the preset condition, directly connecting the rear camera of the vehicle and displaying the image behind the vehicle, which is acquired by the rear camera of the vehicle.
It can be understood that, if the time, and/or the position, and/or the ambient environment information of the vehicle during the current reverse driving is possibly the same as or similar to the time, and/or the position, and/or the ambient environment information corresponding to the previous reverse driving, the car machine may first display at least one frame of image that is closest to the current time during the previous reverse driving of the vehicle, so as to avoid a short black screen phenomenon on a screen of the car machine, that is, avoid a delay phenomenon that occurs between the vehicle receiving the reverse signal and displaying the reverse image on the screen of the car machine. However, if the time and/or position of the vehicle during the current reverse operation and/or the ambient environment information is different from the corresponding time and/or position and/or ambient environment information during the previous reverse operation, the vehicle-mounted device displays at least one image closest to the current time during the previous reverse operation of the vehicle and then displays the image behind the vehicle acquired by the rear camera of the vehicle, which may cause the problem of mismatch between the environments displayed by the front and rear images, for example, the vehicle-mounted device displays the image of the vehicle in the underground parking lot first and then may display the image of the vehicle in the ground parking lot. Therefore, the preset conditions can be set according to actual requirements. In an embodiment, the preset condition includes that the acquisition time and the current time corresponding to the image satisfy a preset time condition and/or the acquisition position and the current position corresponding to the image satisfy a preset position condition. Here, the time condition and the position condition may be set as needed in an actual situation. Therefore, when the acquisition time and the current time corresponding to the image meet the preset time condition and/or the acquisition position and the current position corresponding to the image meet the preset position condition, the target image is displayed first, so that the matching of the displayed image is improved, and the use experience of a user is further improved.
Optionally, the acquiring time corresponding to the image and the current time meet a preset time condition, including: and the difference value between the acquisition time corresponding to the image and the current time is smaller than a preset time threshold value. The time threshold may be set to 30 minutes, 60 minutes, 180 minutes, etc. It can be understood that when the difference between the acquisition time corresponding to the image and the current time is smaller than the preset time threshold, it indicates that the interval time between the current time and the last vehicle reversing is short, and it can be considered that the position of the vehicle, the ambient environment information and the like are not changed basically except for the time change, so that the vehicle machine can display at least one frame of image recorded when the vehicle is reversed last time and closest to the current time, so that the image is always displayed on the screen of the vehicle machine seen by the user when the vehicle reversing operation is started, and the difference between the images displayed before and after is small. Optionally, the acquiring time corresponding to the image and the current time meet a preset time condition, and the method further includes: the acquisition time corresponding to the image is in the same time interval as the current time. It can be understood that, in the daytime and at night, due to the influence of factors such as light intensity, the images for backing up at the same position may have a large difference, and the car machine may not be suitable for displaying the image when the vehicle backs up last time, that is, when the difference between the acquisition time corresponding to the image and the current time is smaller than the preset time threshold, if the acquisition time corresponding to the image and the current time are not in the same time interval, it is indicated that the acquisition time corresponding to the image and the current time do not meet the preset time condition, and the car machine may not be suitable for displaying the image when the vehicle backs up last time first. The time interval can be set according to the actual situation, for example, two time intervals of 6: 00-18: 00 and 18: 00-6: 00 in the morning can be set. Therefore, when the difference value between the acquisition time corresponding to the image and the current time is determined to be smaller than the preset time threshold value and the acquisition time corresponding to the image and the current time are in the same time interval, the target image is displayed first, so that the matching of the displayed image is improved, and the use experience of a user is further improved.
Optionally, the acquiring position corresponding to the image and the current position meet a preset position condition, including: the acquisition position corresponding to the image is the same as the current position or the distance between the acquisition position corresponding to the image and the current position is smaller than a preset distance threshold. It can be understood that, because of the influence of the positioning accuracy, the vehicle may be identified by the same position within a certain position range, or the environmental information within a certain area range of a position, such as parking spaces, flowers, trees, and the like, are substantially the same in plan, and it can be considered that only time has changed, so the car machine can display at least one frame of image that is recorded when the vehicle is backed last time and is closest to the current time, so that the screen of the car machine seen by the user when starting the operation of backing the car is always displayed with images, and the difference between the images displayed before and after is small. The distance threshold may be set according to actual requirements, for example, may be set to 10 meters, 50 meters, and the like. Therefore, when the acquisition position corresponding to the image is determined to be the same as the current position or the distance between the acquisition position corresponding to the image and the current position is smaller than a preset distance threshold value, the target image is displayed first, so that the matching of the displayed image is improved, and the use experience of a user is further improved.
In one embodiment, the image information further includes vehicle surrounding environment information corresponding to the image; the preset conditions further comprise that the vehicle surrounding environment information corresponding to the images and the current vehicle surrounding environment information meet the preset environment conditions. It can be understood that, when the acquisition time and the current time corresponding to the image satisfy the preset time condition and/or the acquisition position and the current position corresponding to the image satisfy the preset position condition, if at least one recorded image closest to the current time when the vehicle backs a car last time is acquired when the vehicle is in a rainy environment, and the current vehicle is in a non-rainy environment, at this time, if the vehicle machine displays at least one image closest to the current time when the vehicle backs a car last time first, and then displays an image behind the vehicle acquired by the rear camera of the vehicle, problems such as mismatch of the displayed environment of the image and the like will be caused, and the use experience of the user will be affected. Therefore, when the acquisition position corresponding to the image is determined to be the same as the current position or the distance between the acquisition position corresponding to the image and the current position is smaller than a preset distance threshold value, the target image is displayed first, so that the matching of the displayed image is improved, and the use experience of a user is further improved.
In summary, in the reverse display method provided in the embodiment, when the reverse signal is monitored and it is determined that the target image of the vehicle during the last reverse operation meets the preset condition, the target image is displayed first, and then the image at the rear of the vehicle, which is acquired by the rear camera of the vehicle, is displayed, so that the display of the reverse image is accelerated, a time delay phenomenon occurring when the vehicle receives the reverse signal and displays the reverse image on the screen of the vehicle machine is avoided, and the use experience of a user is effectively improved.
In one embodiment, the method further comprises: and acquiring and storing image information when the vehicle backs at set time intervals. Optionally, the acquiring and storing the image information when the vehicle is backed at the set time interval includes: and acquiring image information when the vehicle is backed at set time intervals, and refreshing and covering the image information acquired last time when the vehicle is backed according to the image information. Specifically, the car machine collects images of the car when the car is backed and information of the position, time and the like of the corresponding car, which are shot by a rear camera of the car at set time intervals, and refreshes and covers the image information of the last collected car when the car is backed according to the currently collected image information, so that the recording of the image information is realized, and the occupation of a storage space is effectively reduced. It should be noted that the car machine can also collect and store the image information of the car when backing the car in real time. So, through the image information of gathering and the current when backing a car of storage vehicle to show when backing a car next time, further promoted user's use and experienced.
