Abstract
The invention provides a device for up and down calibrating of a vision system of a double-visual-field machine. The device comprises an upper cylinder, a lower cylinder, an upper pressing plate, a lower pressing plate and a V-shaped block, wherein a circular hole for calibrating vision is formed in one end face of each one of the upper cylinder and the lower cylinder; the circular holes and cylindrical faces have high coaxiality; the upper cylinder is mounted on the V-shaped block through the upper pressing plate and the lower cylinder is mounted on the V-shaped block through the lower pressing plate; the upper pressing plate and the lower pressing plate are fixed on the V-shaped block through screws; the lower cylinder is mounted at the lower part of the V-shaped block and the upper cylinder is mounted at the upper part of the V-shaped block; upper and lower positions of the cylinders are adjusted through positions of the pressing plates, relative to the V-shaped block; the vision system of the double-visual-field machine is mounted between the upper cylinder and the lower cylinder; and the position on the upper cylinder is adjusted, so that two cameras in the vision system of the double-visual-field machine obtain suitable circular hole images. The device disclosed by the invention is applicable to calibrating the relative positions of the two cameras in the vision system of the double-visual-field machine.
Description
Technical field
The invention belongs to machine vision calibration technique field, the mode that adopts bicylindrical to be combined with vee-block is used for demarcating two camera relative positions of the Vision Builder for Automated Inspection of double vision open country about having.
Background technology
In the automatic assembling process of micro parts, in order two parts accurately to be located, can adopt the Vision Builder for Automated Inspection with last downward view the position of two parts is measured, according to measurement result the part relative position is accurately adjusted then.Before the Vision Builder for Automated Inspection of last downward view detects the part relative position, need the relative position of two cameras in the vision system is demarcated, can accurately measure preassembled part.This application has designed a kind of device for the wild Vision Builder for Automated Inspection demarcation of double vision, by adjusting the position of demarcating cylinder in the caliberating device, can demarcate the camera relative position in the wild Vision Builder for Automated Inspection of the double vision of different parameters.
Summary of the invention
The present invention is applicable to the demarcation of the relative position of two cameras in the wild Vision Builder for Automated Inspection of double vision.
Technical scheme of the present invention is as follows:
This device comprises cylinder in the round-meshed demarcation of end face, following cylinder, top board, lower platen, vee-block.
Demarcate two cylinders of usefulness through Precision Machining, have higher geometric accuracy; A circular hole that end face has vision calibration to use of last cylinder and following cylinder, circular hole and the face of cylinder have high-axiality; Last cylinder adopts top board to be installed on the vee-block, and following cylinder adopts lower platen to be installed on the vee-block, and last lower platen is fixed on the vee-block by screw; Wherein descend cylinder to be installed on the bottom of vee-block; Following cylinder is installed on the bottom of vee-block, and last cylinder is installed on vee-block top, by adjusting pressing plate with respect to the position of vee-block, adjusts the upper-lower position of this cylinder.
Before assembling, can adopt coordinate measuring machine respectively the relative position of cylinder and circular hole in two cylinders accurately to be measured; Analyze the relative position of two circular holes after the cylinder assembling on the two cylinder end faces.The wild Vision Builder for Automated Inspection of double vision can be placed on up and down between two cylinders, by adjusting the relative position of two cylinders, make two cameras obtain the circular hole image of high definition, by computing machine the relative position of the circular hole image that obtains is carried out analyzing and processing, can reach the purpose of demarcating two camera relative positions.
