摘要
Abstract
The issue of screen lag when speedometer images are drawn in full LCD instrumentation systems is addressed by proposing a display anti-lagging technology based on an image format mapping strategy.The optimization of speedometer image loading rate is taken as the entry point for the establishment of the image format mapping function,which in turn yields the parameters of the image header information structure by format preprocessing.The descending order of pixels is then realized based on the number of color occurrences to determine the main color of the image,and the color segmentation parameters are further obtained based on the characteristics of the main color.Meanwhile,the automatic preloading mode characteristics are clarified,and the working mechanism of asynchronous loading image resources is revealed.The test results show that the optimized speedometer has no lag when drawing images,its accuracy rate of display is 98.9%,its average response time of vehicle speed increase and decrease is reduced by 0.14 s and 0.12 s,respectively,and its response time under various working conditions is lower than that of the speedometer before optimization,which verifies that the designed anti-lagging technology can improve the image loading rate and system performance effectively.关键词
