Digital optical imaging measuring device and method

Abstract

A measuring device of digital optical image consists of multiple digital optical image picking up unit for picking up digital optical image of object and for transmitting picked up image, a power unit for driving said picking up unit, a operation unit for controlling actions of picking up unit and power unit, a processor being connected to said picking up unit and being used to receive image information as well as comparing similarity of obtained image information to create a decision result, and a display unit for displaying said decision result. The method for measuring digital optical image is also disclosed.

Description

technical field [0001] The present invention provides a digital optical image measurement method and its device. In the detection process, a group of images of standard objects are used to verify the degree of difference between the comparison objects, thereby achieving the effect of rapid comparison. Background technique [0002] At present, various printed circuit board (PCB, Printed Circuit Board) manufacturing processes, on a printed circuit board (Printed Circuit Board Panel), in response to the needs of various sizes or manufacturing processes, and manufacture multiple circuit boards, and their arrangement Also different. In addition, according to customer requirements or quality control regulations, there are different restrictions on the defect rate of circuit boards on each circuit board. For example, one circuit board may be allowed to be defective on the circuit board, or three circuit boards may be allowed on the circuit board. It is a defective product, that is...

Problems solved by technology

Among them, because the "observation device", "instrument" or "identification device" is used to move between several reference points to calculate the distance between several reference points, it takes a very long time to move the "observation device", "instrument" accurately ” or “identification device”, and if more reference points are needed to calculate the distance between reference points due to increased accuracy, the time required to move the “observation device”, “instrument” or “identification device” will be even greater

In addition, if the reference point is incomplete due to manufacturing errors or artificial damage during the product process, it will directly affect the accuracy, resulting in the inability to correctly detect whether the circuit board is located in the standard position of the circuit board and make the circuit boards on the market good. rate decline and damage to the goodwill of circuit board manufacturers

[0007] In the prior art, relative to the product inspection measurement method and its device, several reference points are used to measure alternately with each other, which may not be able to provide a comprehensive and complete solution for today's fast and convenient precise measurement requirements
