Background technology.
Engine link is the vitals for realizing cycle of engine work and energy conversion.Engine operationally,
At this moment piston is accomplished by making automobile bent by the effect of connecting rod due to the effect meeting line activities in the cylinder by gaseous-pressure
Axle is rotated, and needs outwards to export power by bent axle；And in air inlet, compression and exhaust process, flywheel
Can give off energy, so again can by the convert rotational motion of bent axle into piston up and down motion.In the middle of the process of acting,
Piston guarantees that piston can be moved along a straight line due to receiving the pressure that burning gases expansion is produced by connecting rod, and will be living
The transform linear motion of plug becomes the rotary motion of bent axle, and to outside output power.In Long-Time Service, connecting rod long-time
Under being operated in powerful machinery heavy burden and rugged environment so that connecting rod easily weares and teares, and the precision of connecting rod size is directly affected
The performance of engine.
The content of the invention
Accurate measurement is carried out in order to carry out big hole diameter and centre-to-centre spacing to connecting rod, the invention provides a kind of be based on machine
The connection rod of automobile engine geometric parameter detecting system of vision.
A kind of connection rod of automobile engine geometric parameter detecting system based on machine vision, including host computer, for host computer
Parameter input module, controller and the image pick-up card of reduced parameter are input into, the host computer can send control signal to institute
State image pick-up card and obtain geometric parameters after the upper computer module to gather the image information of connecting rod, and calculate through controller
Number.
Preferably, also including a drive module, then the drive module can convert control signal that controller sends
Transmit successively to one and be laterally fed motor, a CCD camera and described image capture card.
Preferably, the host computer includes the display module for display data.
Preferably, the system also includes that one can provide the LED/light source of light and for the system provide electricity for the system
The power module in source.
Machine vision refer to using vision sensor obtain picture and using image processing system carry out it is various measurement and
Judge.In industrial processes, the increasingly raising of the increasingly automated and product quality of production process, it is desirable to have more effectively,
The more detection means of accurate and high speed, the connection rod of automobile engine geometric parameter based on machine vision provided by the present invention
