Embodiment Construction
[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0029] The present invention proposes to generate a detection template picture offline for each illustrated road condition SVG template, and perform pixel comparison with the illustrated road condition picture generated online, and find out whether there is an unexpected color value in the illustrated road condition through comparison. Then evaluate the rendering quality of the illustrated road conditions.

The invention provides an automatic detection method and system of graphic representation road condition. The method comprises that a detection template picture is generated offline; the detection template picture is compared with a graphic representation road condition picture online; and whether the graphic representation road condition picture is rendered successfully is determined according toa comparison result, and foreground pixels of the graphic representation road condition picture are re-rendered when rendering fails. An online comparison method comprises that the detection templatepicture and the graphic representation road condition picture are scanned synchronously, an error proportion of background and foreground pixels in the graphic representation road condition picture are determined, if the error proportion is beyond a set threshold range, it is determined that picture rendering fails, and otherwise, it is determined that picture rendering succeeds. The automatic detection method for the generation quality of a graphic representation road condition product based on pixel comparison is provided, a distributed graphic representation road condition rendering systemcan be detected and corrected effectively when substandard products appear, and the user experience is improved.
Description
technical field [0001] The invention relates to the fields of computer technology and intelligent transportation, in particular to a method and means for detecting the quality of generated road condition products based on automation. Background technique [0002] With the continuous development of dynamic traffic information services, the product forms of traffic information services are also constantly enriched and improved, and the illustrated road conditions are one of the more common service forms. [0003] Based on the technology disclosed in the invention patent "Automatic Generation Method and System for Graphical Road Conditions" (invention patent application number 201110399132.2, such as figure 1 As shown, the illustrated road condition is a product form that simulates and displays the content of the traffic variable message sign (Variable Message Signs, VMS) on the vehicle navigation terminal. Compared with the VMS equipment built on the roadside, the illustrated...
