Problems solved by technology

In this way, the function of automatic guidance is not realized at all. The amount of terrain data that needs to be marked manually is large, and the universality of the terrain cannot be taken into account. The performance of terrain recognition depends on the terrain sample library. Due to the variety of terrain, the terrain sample library is difficult to cover all types. Terrain, the correct rate of terrain recognition is greatly affected by the training process of the classifier, basically all conventional terrain classifiers have such problems

Embodiment Construction

[0019] Below with reference to accompanying drawing and in conjunction with embodiment, structural feature and technical implementation process of the present invention are described in detail:

[0020] like figure 1 As shown, the system uses the trinocular vision system to collect images of the terrain, and the three cameras of the trinocular stereo vision system are placed in the same direction and at the same distance. The trinocular stereo vision system has a narrow baseline of 0.12m using the left and middle cameras and a wide baseline of 0.24m using the left and right cameras. A narrow baseline increases the common field of view of both cameras, and a wide baseline has a larger maximum field of view per viewing distance. The three cameras of the trinocular stereo vision system shoot three terrain images from different angles, and then use the stereo vision matching algorithm to obtain the depth information of the terrain. After obtaining the 3D information of the terra...

Abstract

The invention discloses a landform classification method based on a trinocular visual system, which comprises the following steps firstly sampling the landform and outputting abundant 3D data by a trinocular three-dimensional visual system; then transmitting 3D data to a geometrical classifier, and in consideration of color characteristics of the landform, finally differentiating the landform through a color classifier. The landform classification method has functions of realizing simple and quick vehicle automatic guiding based on the trinocular visual system, preventing large-data-volume training, and realizing no requirement for manual landform marking. The trinocular visual system can be used as a supplement for a complicated vehicle automatic guiding system, and furthermore can be prepared to a simple object transport trolley automatic guiding system. The landform classification method has good market prospect.

Description

technical field [0001] The invention relates to a vehicle automatic guidance device, in particular to a terrain classification method based on a trinocular vision system. Background technique [0002] Vehicle automatic guidance is the core research part of vehicle automatic driving. The development of modern artificial intelligence technology makes vehicle automatic guidance technology more mature. Since Electronic launched the first automatic guided vehicle system and put it into industrial production, the automatic guidance of the vehicle has gradually entered the industrial and agricultural production and terrain detection, the transportation of goods in the warehouse, the automatic driving of the Mars rover and other applications have been familiar to everyone . At the same time, the technology of terrain detection using image recognition has gradually attracted attention, but there are still deficiencies in the design of classifiers. Traditional classifiers cannot aut...
