Embodiment Construction

[0034] like figure 1 As shown, the present invention provides a method for controlling a safe vehicle speed based on image recognition, comprising the following steps:

[0035] (1) Obtain the live image of the driving direction;

[0036] (2) Convolutional neural network is used to identify the speed limit sign from the live image to obtain the speed limit value;

[0037] (3) Comparing the current vehicle speed and the speed limit value, if overspeed, execute step (4), otherwise execute step (5);

[0038] (4) Control the vehicle to decelerate so that the current vehicle speed is lower than the speed limit;

[0039] (5) Return the speed limit value through the visualization device.

[0040] In the above method, the speed limit sign and the speed limit value are more efficiently and accurately identified through the convolutional neural network.

[0041] Optionally, in step (3), the current vehicle speed is acquired through OBD (ie on-board automatic diagnosis system).

Abstract

The invention provides a safe vehicle speed control method based on image identification. The safe vehicle speed control method includes the following steps that (1) a live image in the driving direction is obtained; (2) a convolutional neural network is used, a speed limiting identification is identified from the live image, and a speed limiting value is obtained; (3) the current vehicle speed is compared with the speed limiting value, if overspeed, a step (4) is executed, otherwise, a step (5) is executed; (4) an automobile is controlled to subjected to the deceleration operation, and thus the current vehicle speed is below the speed limiting value; and (5) the speed limiting value is returned through visualization equipment. Compared with the prior art, the safe vehicle speed control method has the beneficial effects that through the convolutional neural network, the speed limiting sign and the speed limiting value are identified more efficiently and accurately, and a vehicle is effectively controlled to conduct reasonable deceleration processing.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to an image recognition-based safe vehicle speed control method and system thereof. Background technique [0002] With the sharp increase in car ownership and vehicle travel, traffic safety issues have become increasingly prominent. In order to solve various traffic problems arising from this, the industry began to vigorously develop ITS intelligent transportation system (Intelligent Transportation System). The core technology of ITS intelligent transportation system involves digital signal processing, communication technology, image processing, pattern recognition, artificial intelligence, such as unmanned driving is its typical application. [0003] A key technology of the ITS intelligent transportation system is road traffic sign recognition, especially the information collection and recognition of vehicle speed limit signs that appear on the road while the vehicle is drivi...
