Abstract

The invention discloses a structure device based on fusion of a monocular camera and a laser radar. The structure device comprises a base, a first fixed seat, a second fixed seat, a first sealing piece, a second sealing piece and a plano lens. The laser radar is hermetically connected to a top of the first fixed seat through the first sealing piece; a monocular camera module is fixed on a verticalsurface of the second fixed seat, the second fixed seat and the monocular camera module are fixed in an internal portion of the first fixed seat, a first through hole for light transmission of the camera is arranged in a side surface of the first fixed seat, and the plano lens is sealed at the first through hole; and a bottom of the first fixed seat is connected to the base in a sealed mode through the second sealing piece. The device has waterproof and dustproof functions, integrates the camera and the laser radar into a whole, and is compact in structure, high in stability, small and exquisite in overall appearance, small in occupied space during installation, simple in structure, easy to assemble and convenient to install.

Description

technical field [0001] The invention belongs to the field of unmanned driving, and relates to a structural device based on the fusion of a monocular camera and a laser radar. Background technique [0002] In the field of unmanned driving, sensors play a vital role. They sense the surrounding environment to obtain information such as images, distances, speeds, etc., so that the car can drive safely. Cameras and LIDAR are the most common sensors in cars, and they have their own strengths and weaknesses for sensing their surroundings. The advantage of the camera lies in the recognition of objects. It can perform detailed classification and recognition of license plates, signs, pedestrians, lane lines, etc.; Obtain the three-dimensional information of the object, and it has high stability and good robustness. The disadvantage of the camera is that it is difficult to accurately obtain the three-dimensional information of the object, and it is greatly affected by the ambient lig...
