Abstract

The present invention provides a vehicle speed warning system and method for acquiring the images thereof. There is a speedometer image acquisition device, mounted correspondingly to the speedometer of the existing panel, and used to acquire the images of the speedometer. An image converter converts the images acquired by a speedometer image acquisition device into digital image data. A processor is used to receive digital image data and analyze the rotating angle of the pointer of speedometer. A memory stores the program of the vehicle speed warning system and digital image data of the speedometer. A display screen displays the speed value and/or the judgment result analyzed by the processor. The setting unit sets the warning threshold of the pointer angle of speedometer. A warning device, used to send a warning signal when the pointer angle of the speedometer exceeds the warning threshold set by the driver.
