The invention provides a display method of graphs in a reversing image system and the reversing image system. A graph grade signal screening module analyzes radar signal grades from received radar signals; the graph azimuth signal screening module analyzes radar signal grade and azimuth information from the received radar signals; the graphic level signal screening module generates graphic control signals corresponding to each radar signal level and sends the graphic control signals to the display refreshing module; wherein the graph control signal is used for controlling the refresh frequency of the graph to be displayed; the graphic orientation signal screening module determines graphic display information of a corresponding to-be-displayed graphic according to each radar signal grade and orientation information, and sends the graphic display information to the display refreshing module; and the display refreshing module calls and displays the to-be-displayed graph according to the graph display information under the control of the graph control signal. Therefore, a plurality of graphs with the same radar signal level can be synchronously displayed, and the refresh frequencies of the graphs are consistent.
本申请提供了一种倒车影像系统中图形的显示方法及倒车影像系统,图形等级信号分筛模块从接收到的雷达信号中解析出雷达信号等级;图形方位信号分筛模块从接收到的雷达信号中解析出雷达信号等级和方位信息;图形等级信号分筛模块生成每种雷达信号等级对应的图形控制信号,并发送给显示刷新模块;其中,图形控制信号用于控制待显示图形的刷新频率;图形方位信号分筛模块根据每种雷达信号等级和方位信息确定对应的待显示图形的图形显示信息,并发送给显示刷新模块;显示刷新模块在图形控制信号的控制下,根据图形显示信息调取待显示图形并显示。这样,能够同步显示相同雷达信号等级的多张图形并保证图形的刷新频率一致。
