摘  要
本次毕业设计主要内容是在CATIA和AUTOCAD软件平台上完成对车载双目视觉系统的机械结构设计。整个设计的核心在于要实现车载双目摄像机系统的横摆运动以及俯仰运动，以便传送给汽车的中央处理器更加清晰准确的画面，用来判断汽车行进道路上的障碍物体。本次设计的主要模块有摄像机模块、俯仰运动机构、横摆运动机构、减振器四个大的部分。利用三相步进电机和直线式步进电机来分别提供俯仰运动和横摆运动的动力，通过一定减速机构来增加步进电机输出的扭矩，使扭矩满足系统的需要，通过减振器来连接汽车车顶与整个车载双目系统，从而减少汽车行进时汽车传给车载双目系统的振动，最大程度的保证车载双目视觉系统的稳定性，通过以上四部分来保证车载双目视觉系统功能的完整性和稳定性。

Abstract
The main content of this graduation design is to complete the mechanical structure design of the vehicle-mounted binocular vision system on the CATIA and AUTOCAD software platforms. The core of the entire design is to achieve the horizontal movement and pitch movement of the vehicle-mounted binocular camera system so that the central processor of the car can send a clearer and more accurate picture to determine the obstacle objects on the road of the car. The main modules of this design are camera module, pitch motion mechanism, pendulum motion mechanism, shock absorber four large parts. Three-phase stepper motor and linear stepper motor are used to provide the power of pitch motion and horizontal pendulum motion, respectively, and the torque of stepper motor output is increased by a certain deceleration mechanism, so that the torque meets the needs of the system. The vibration absorber is used to connect the car roof with the entire vehicle binocular system, thus reducing the vibration of the car to the vehicle binocular system when the car is moving, and ensuring the stability of the vehicle binocular vision system to the maximum extent. The above four parts are used to ensure the vehicle binocular system.Three-phase stepper motor and linear stepper motor are used to provide the power of pitch motion and horizontal pendulum motion, respectively, and the torque of stepper motor output is increased by a certain deceleration mechanism, so that the torque meets the needs of the system.
