Embodiment Construction

[0055] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0056] to combine figure 1 , the invention provides a method for colorizing a three-dimensional reconstruction of a vehicle-mounted infrared image, comprising the following steps:

[0057] Step 1. Acquiring a plurality of vehicle-mounted infrared original images and classification images corresponding to each vehicle-mounted infrared original image;

[0058] Step 2. Use the Rolls mask to perform multi-scale feature extraction of base pixels on the original vehicle-mounted infrared image, and form a colorized training set with the corresponding classified images;

[0059] Step 3. Use the colorized training set to train a random forest classifier;

[0060] Step 4, use the Rolls mask to perform multi-scale feature extraction of base pixels on the vehicle-mounted infrared image to be tested, and then input it into the trained random...

Abstract

The invention discloses a vehicular infrared image colorization and three-dimensional reconstruction technology which is characterized in that a colorization algorithm based on a random forest classifier and a three-dimensional reconstruction algorithm based on panel parameter estimation are integrated to perform three-dimensional reconstruction on a vehicular infrared image. The method of the invention has the following advantages: an infrared image colorization technology and an infrared image three-dimensional reconstruction technology are integrated, which enables an infrared image to be displayed more visually; the method is applicable to colorization of a variety of vehicular infrared scenes and can obtain a good colorization result; and the method is applicable to changing road scenes.

Description

technical field [0001] The invention relates to a colorized three-dimensional reconstruction method of a vehicle-mounted infrared image based on a random forest and a panel parameter Markov model. Background technique [0002] With the popularization of vehicle-mounted infrared assisted driving systems in the civilian field, the research work on vehicle-mounted infrared has gradually attracted people's attention. Depth estimation of infrared images has become a research hotspot in recent years. [0003] Since the vehicle-mounted infrared image is a grayscale image, it has the characteristics of low contrast and low recognition, which is not convenient for the driver to observe this type of image. In order to make the vehicle-mounted infrared image easier to express all the information contained in the vehicle driving, it is necessary to use image processing technology to process the vehicle-mounted infrared image to make it more in line with human visual habits. [0004] W...
