Embodiment Construction

[0024] At present, research on bionic eyes and visual platforms at home and abroad has its own emphasis and characteristics. Most of the research programs are based on the visual platform based on rotating motors. The present invention uses linear motors with high speed, high precision, and high responsiveness. As a drive unit, and a new design for the structure of the bionic eye movement platform. According to the mechanism of human eye movement, linear motors can be used to replace eye muscles to simulate eyeball rotation and realize the vision movement of the bionic eye movement platform.

[0025] Below in conjunction with accompanying drawing and example the present invention is described in further detail.

[0026] The bionic vision platform driven by multi-axis linear motors provided by the present invention includes a base frame 9, a host computer 1, an image acquisition card 2, a camera 8, a motion control card 11, a first driver 3, a second driver 10, a vertical linea...

Abstract

The invention provides a bionic vision platform driven by a multi-axis linear motor, including a host, a motion control card, a motion mechanism, a camera and an image acquisition card. The above-mentioned parts are connected in series to form a closed loop, and the host controls the motion mechanism through the motion control card. , the motion mechanism drives the camera to rotate, the camera collects images, and outputs them to the host computer through the image acquisition card. The motion control card controls the movement of the vertical and horizontal linear motors. The mover of the horizontal linear motor is vertically fixed to the stator of the vertical linear motor. The connecting block is connected to the mover of the vertical linear motor. Two connecting rods are arranged in parallel. One end of the connecting rod is connected with the connection block, and the other end is connected with the camera. The platform controls the two degrees of freedom of the bionic eye through two linear motors, and the rapid movement of the two linear motors ensures that the camera can capture dynamic objects and targets, and can well complete various posture adjustments of the bionic eye, and is capable of dealing with complex work requirements in the environment.

Description

technical field [0001] The invention belongs to the technical fields of machine vision technology and linear motor control, and in particular relates to a bionic vision platform driven by multi-axis linear motors. Background technique [0002] Machine vision is a comprehensive technology including digital image processing technology, mechanical engineering technology, control technology, electric light source lighting technology, optical imaging technology, computer software and hardware technology and human-machine interface technology. Because the machine vision system can quickly acquire a large amount of information, and is easy to integrate with design information and processing control information, machine vision technology has increasingly attracted people's attention as a means of detection and control and has been widely used in industrial control. application. [0003] Linear motor is a transmission device that directly converts electrical energy into linear motio...
