Problems solved by technology

[0008] The technical problem to be solved by the present invention is: to provide a method for establishing a database containing visible light images and infrared images of vehicles, respectively collect visible light images and infrared images of the same type of vehicles, mark the rectangular area containing the vehicle in the collected images, and adjust the rectangular area. The area is a square area, and the vehicle image is intercepted in a square area, and adjusted to a square image with a specified side length of 20 to 120 pixels. The visible light image and infrared image of the same vehicle type are stored in their own folders, which overcomes the existing technology. The vehicle image database cannot reflect the visible and infrared features of the vehicle at the same time, and has the defect of focusing on the visible light features of the vehicle and ignoring the infrared features of the vehicle, or focusing on the infrared features of the vehicle and ignoring the visible light features of the vehicle

Embodiment 1-1

[0109] The vehicle described in this embodiment is a car.

[0110] Step 1, prepare the visible light image of the vehicle:

[0111] Step 1-1, collect the original visible light image of the vehicle:

[0112] Through the photographing method, the visible light image of the vehicle including the background is collected as the original image of the visible light image of the vehicle processed in the following steps. In addition to the specified type of visible light image of the vehicle, other visible light images of the vehicle are allowed in the original image of the visible light image of the vehicle , and can identify the specified vehicle shape in the vehicle image database to be prepared;

[0113] figure 2 It is a schematic diagram of the original visible light image of a car collected in this embodiment.

[0114] figure 2 It shows that the real sample of this picture is the effect picture of the color photo of the real scene after grayscale transformation and edge ex...

Embodiment 1-2

[0181] The vehicle described in this embodiment is a car.

[0182] Step 1, prepare the visible light image of the vehicle:

[0183] Step 1-1, collect the original visible light image of the vehicle:

[0184] With embodiment 1-1.

[0185] Step 1-2, initially mark the rectangular area containing the vehicle in the collected original visible light image of the vehicle:

[0186] With embodiment 1-1.

[0187] Steps 1-3, determine whether it is necessary to adjust the original visible light image of the vehicle to initially mark the rectangular area containing the specified type of vehicle as a square area and the processing method:

[0188] Set the original visible light image of the vehicle to initially mark the rectangular area containing the specified type of vehicle. The horizontal length of the upper side and the lower side is a, the vertical length of the left side and the right side is b, and the unit of a and b is pixel. Compare The length of a and b is processed as fol...

Abstract

The invention includes a method for establishing a database of visible light images and infrared images of vehicles, and relates to a traffic control system for road vehicles. The method collects visible light images and infrared images of vehicles of the same type respectively, and marks a rectangular area containing the vehicle in the collected images. Adjust the rectangular area to a square area, intercept the vehicle image with the square area, and adjust it to a square image with a specified side length of 20 to 120 pixels. The visible light image and infrared image of the same vehicle type are stored in their own folders, which overcomes the existing technology. The vehicle image database in the system cannot reflect the visible light characteristics and infrared characteristics of the vehicle at the same time, and has the defect of focusing on the visible light characteristics of the vehicle and ignoring the infrared characteristics of the vehicle, or focusing on the infrared characteristics of the vehicle and ignoring the visible light characteristics of the vehicle.

Description

technical field [0001] The technical proposal of the invention relates to a traffic control system of road vehicles, specifically a method for establishing a database of visible light images and infrared images of vehicles. Background technique [0002] With the increase of the number of vehicles, traffic control in intelligent transportation needs to identify vehicle types, and vehicle identification is also an important direction of intelligent driving. The increase in the number of vehicles provides convenience for people to travel, but also increases the difficulty of traffic control. It is necessary to effectively detect vehicle types and control traffic flow, analyze traffic congestion, quickly find vehicles that cause trouble, and determine the type of vehicles passing through toll stations. Therefore, vehicles Type detection has become an important part of intelligent transportation, and it has also become a development direction for intelligent driving transportatio...
