Embodiment

[0041] Such as figure 1 As shown, the driver's face positioning system based on the fusion of distance images and intensity images includes an image acquisition device, an image processing device, and a positioning device. The image acquisition device includes a distance image sensor, 2 infrared cameras, and 1 CMOS camera. The device is installed above the dashboard of the vehicle. Based on the frontal face image of the driver facing the front of the vehicle, the vehicle starts Finally, the camera is used to obtain the distance image sequence and the intensity image sequence to obtain the state information of the driver's head and the vicinity of the head in real time. A range image sensor and two infrared cameras are used to acquire range image sequences; a CMOS camera is used to acquire intensity image sequences.

[0042] The image processing device adopts a DSP processing system, and the DSP processing system uses an image processing-based method to process video images. ...

Abstract

The invention discloses a driver's face positioning system based on distance images and intensity images, which includes an image acquisition device, an image processing device and a positioning device, and is characterized in that the image acquisition device includes at least one distance image sensor, one A CMOS camera and 2 infrared cameras are used to collect the intensity image and the distance image of the driver in real time, and transmit the intensity image and the distance image collected to the image processing device; the image processing device is used to collect the driver's image The intensity image and the distance image are processed; the positioning device is used to identify the driver's face position and size according to the processed intensity image and distance image, and to track the face image and locate the driver's face position. Based on the fusion of distance images and intensity images, the system improves the accuracy of driver's face location.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a driver's face positioning system based on distance images and intensity images. Background technique [0002] With the continuous development of social economy and the continuous growth of car ownership data, the issue of car safety is particularly important. Automobile safety can be divided into passive safety and active safety: passive safety refers to minimizing the damage of passengers and pedestrians after traffic accidents; active safety refers to avoiding accidents by taking precautions in advance. Passive safety technology developed early, such as airbag technology, which has already entered the mature stage of technology and has been widely used; with the great progress of computer, machine vision, electronics, communication and other technologies, research in the field of active safety has also developed rapidly. Among them, since the d...
