Embodiment Construction

[0045] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0046] Road traffic sign detection and recognition methods, such as figure 1 shown, including the following steps:

[0047] In one embodiment, the region of interest is extracted, and the region of interest of traffic signs is extracted from the input image to be detected; in this embodiment, common bans, instructions and warning signs in domestic urban roads are used as research objects, common prohibitions, instructions The colors of warning signs and warning signs are mainly red, blue and yellow. When the light is too bright or too dark, the blue component of the blue area in the RGB image is very close to the value of the green component. Preferably...

Abstract

The present invention provides a road traffic sign detection and identification method. The method comprises the steps of: extracting a region of interest; performing multi-scale sliding traversal; merging image features; and identifying a traffic sign. The method specifically comprises: performing extraction of a region of interest of the traffic sign on an input to-be-detected image; convertingthe to-be-detected image into a gray-scale image; constructing a binary mask image of the region of interest of the traffic sign; performing multi-scale sliding traversal on the gray-scale image and the binary mask image to obtain position coordinates of a detected target; merging the extracted local texture features, local image region features and global features of the to-be-detected image; andclassifying and identifying the merged image features by using a classifier. The present invention relates to an electronic device and a readable storage medium for performing the road traffic sign detection and identification method; and the present invention also relates to a road traffic sign detection and identification system. The technical scheme of the present invention has a high detection rate, a high identification rate, a fast calculation speed, a low false detection rate and good robustness.

Description

technical field [0001] The invention relates to the technical field of vehicle assisted driving, in particular to a road traffic sign detection and recognition method, an electronic device, a storage medium and a system. Background technique [0002] With the development of society and economy and the improvement of people's living standards, vehicles have been widely popularized. The traffic sign recognition (Traffic Sign Recognition, TSR) system is a key component of the driver assistance system (Driver Assistance Systems, DAS) and the automatic driving system (Autonomous Driving Systems, ADS). The incidence of traffic accidents is of great significance. The road traffic conditions in the driving environment are complex and changeable, and are affected by the speed of the vehicle, which makes the detection and recognition of traffic signs more difficult. The current traffic sign detection and recognition methods have the following deficiencies: the traffic sign detection...
