Special vehicle auxiliary driving system based on stereoscopic vision

Abstract

The invention discloses a special vehicle auxiliary driving system based on stereoscopic vision. The special vehicle auxiliary driving system comprises a binocular stereoscopic vision detection unit,a video image processing unit, a stereoscopic display helmet and a connecting cable. The binocular stereoscopic vision detection unit is arranged outside a vehicle and used for observing the externalenvironment, the binocular stereoscopic vision detection unit comprises a binocular camera and a two-axis holder, and the binocular camera is installed on the two-axis holder; and the binocular cameratransmits the obtained video to a video image processing unit located in the vehicle, and the video image processing unit performs three-dimensional reconstruction on the video image and then transmits the video image to a three-dimensional display helmet for display. According to the invention, the road condition information outside the vehicle can be obtained in real time, and meanwhile, the image processing unit in the vehicle enables the obtained video image to have the functions of fog penetration, low illumination enhancement and the like through an image processing algorithm, thereby improving the environmental adaptability of the vehicle.

Description

technical field [0001] The invention belongs to the field of vehicle auxiliary driving, and in particular relates to a special vehicle auxiliary driving system based on stereo vision. Background technique [0002] The driving of special vehicles generally adopts two kinds of auxiliary driving devices: periscope and camera device. A periscope refers to a device that protrudes from the sea surface to the sea surface or from a low-lying tunnel to spy on activities on the sea surface or on the ground. Its structure is the same as that of ordinary ground telescopes, except that two additional reflectors are added to make the object light reflect twice and then turn toward the eyes. Periscopes are often used in submarines, tunnels and tanks to observe the enemy's situation, and are also used in special vehicles to assist driving. At present, the periscope is still the most widely used auxiliary driving device for special vehicles, but the field of view of the periscope is narrow...

Problems solved by technology

[0004] However, according to feedback from drivers who use camera-assisted driving devices to drive vehicles, due to the poor sense of distance in the front two-dimensional images acquired by the camera device, it cannot provide accurate information on the distance of obstacles, so that drivers need to slow down in advance when they find obstacles. moving, which affects the driving speed
