The invention discloses a velocity-limiting mark recognizing and vehicle-velocity control method and system based on a vehicle traveling recording instrument. The method includes the steps that the vehicle traveling recording instrument collects an image through a camera in real time and carries out intensification and de-noising processing on the image; the processed image is compared with a pre-stored database template with a road velocity-limiting mark to judge whether the velocity-limiting mark exists in the image or not, and if the velocity-limiting mark exists in the image, the velocity-limiting mark is recognized to obtain the velocity-limiting velocity; the current vehicle velocity is adjusted according to the obtained velocity-limiting velocity. According to the velocity-limiting mark recognizing and vehicle-velocity control method and system, the vehicle-traveling velocity-limiting mark exists in a current road section is automatically recognized through the vehicle traveling recording instrument of a vehicle, a control command is output according to the recognition result, and the vehicle velocity is automatically controlled; meanwhile, a driver learns the velocity-limiting information of a road in real time, the driving safety of the driver is improved, and unnecessary traffic accidents are reduced.
