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.

Claims

1. A vehicle speed warning system for acquiring images of a speedometer, the system comprising:

a speedometer image acquisition means, being mounted and used to acquire the images of the speedometer;

an image converter means to convert the images acquired by said speedometer image acquisition device into digital image data;

a processor means with image processing and judgment capability to receive said digital image data from the image converter, analyzing a rotating angle of said speedometer;

or digital changes of said speedometer;

a memory means to store a program and digital image data of said speedometer;

a display screen means to display speed value or judgment result or both analyzed by the processor means;

a setting unit setting warning threshold of the pointer angle of speedometer; and

a warning means, being linked to the processor means, when the pointer angle of said speedometer exceeds a warning threshold set by a driver, a warning device sending a warning signal.

2. The system defined in claim 1, wherein the speedometer image acquisition device implements through CMOS (Complementary Metal-Oxide Semiconductor) or CCD (Charge Coupled Device).

3. The system defined in claim 1, wherein said warning means comprises a loudspeaker or a buzzer.

4. A vehicle speed warning method for acquiring images of a speedometer, comprising:

mounting a speedometer image acquisition device corresponding to the speedometer of an existing panel and acquiring images of the speedometer;

converting the images acquired by the speedometer image acquisition device into digital image data for output using an image converter;

receiving digital image data from the image converter, processing and judging the images, and analyzing a rotating angle of the pointer of said speedometer or digital changes of speedometer using a processor;

storing a program of a vehicle speed warning system and digital image data of the speedometer in a memory;

displaying said pointer angle of the speedometer or judgment result of speed analyzed by the processor or both, using a display screen;

setting warning thresholds of pointer angles or digital changes of speedometer by a setting unit; and

sending a warning signal, when said pointer angle of the speedometer exceeds a warning threshold.
