Embodiment Construction

[0019] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0020] The main purpose of a vehicle-mounted infrared assisted driving system provided by the present invention is to improve the safety of automobile driving. The information of vehicles, road conditions and pedestrian conditions can be obtained through the infrared camera installed on the vehicle. The colorized result map finally realized by this system is as follows Drivers provide useful information.

[0021] Such as figure 1 As shown, the system structure provided by the present invention mainly includes: FLIRA615 vehicle-mounted night vision device, digital processor DSP DM642, vehicle-mounted screen, power supply and so on.

[0022] The image acquisition module composed of FLIR A615 infrared thermal imager and DSP DM642 is used for real-time image acquisition, and the collected data is quickly uploaded to DSP DM642 through...

Abstract

The invention relates to a vehicle mounted infrared image colorizing assistant driving system comprising an infrared thermal imaging device mounted on a vehicle. The device is connected to a digital processing unit mounted on the vehicle and acquires infrared images in real time to transmit to the digital processing unit, and infrared images are processed through the digital processing unit before being displayed through a display unit of the vehicle. According to the system, an infrared image colorizing scheme in a night vision environment is provided, the problem that pure infrared gray images are difficult to recognize in the prior art is overcome, the ability of a driver acquiring road information at night is improved, an important reference is provided for night driving, and the traffic accidents can be reduced greatly.

Description

technical field [0001] The invention relates to a vehicle-mounted infrared night vision auxiliary driving system, in particular to a colorization system for vehicle-mounted infrared night vision images. Background technique [0002] With the rapid development of the automobile market and the increasing awareness of security, people have higher and higher requirements for automobile safety technology, and the vehicle-mounted infrared assisted driving system has gradually entered our lives. It can acquire infrared images of scenes such as roads and roadside trees and buildings at night, but the infrared image has no color, it is a grayscale image without shadows, and the contrast is low, so for the human eye, the resolution is low and the visual effect is blurred . Since the color level that the human eye can distinguish is hundreds of times the gray level, if the vehicle-mounted infrared image is colored, it will greatly improve the visual understanding of the image and help...
