ABSTRACT
In order to improve the efficiency and accuracy of manual detection of automotive
dashboard testing, it is particularly important to use computer vision-related technology to
identify pointer readings and icon information of automobile dashboard in automotive
dashboard function detection. In this paper, the traditional computer vision technology is
applied to identify the automobile dashboard. The pointer reading is recognized by the
Hough line detection, and the template matching is applied in each ROI area to determine
the lighting and extinguishing of the dashboard indicator. The method realizes the reading
of the tread gauge, the speedometer and other pointer instruments of the auto dashboard, as
well as the lighting and extinguishing of the steering lights, fog lights and other automotive
indicators. The experimental results show that the accuracy of the algorithm's recognition of
pointer readings on the dashboard is more than 90%, the accuracy of the identification of
indicators is more than 75%, and the average time of frame processing is currently 4.516s, which still needs to be improved.
