Optical Image Correction System

Abstract

The invention provides an optical image correction system which is mainly used for correcting an AOI drilling crew. The optical image correction system mainly comprises a dot matrix device and a correction device. The dot matrix device comprises a bottom plate and a dot matrix plate arranged on the bottom plate, and the dot matrix plate is provided with multiple rows of windows distributed in a dot matrix mode. The correction device mainly comprises a scanning unit, an adjusting unit and a storing unit, wherein the scanning unit is used for scanning the image of the dot matrix plate on the dot matrix device, the adjusting device is used for comparing the scanned image of the dot matrix plate and the windows of the dot matrix plate and updating and adjusting the position of an original point in the window at the lowermost right corner so that the windows of the dot matrix plate and the scanned image of the dot matrix plate can be overlapped, the storing unit is used for storing the updated position of the original point, and thus the correction process is completed. According to the optical image correction system, by means of correction, the real condition is presented in photos shot by the AOI drilling crew, the coordinates of an element model can be exactly matched with the actual element position, the purpose of correcting image deformation is achieved, and the problem that tools for correction are not available previously, the image deformation issue is generated, and using cannot be achieved is solved.

Description

technical field [0001] The invention relates to an image correction device, in particular to an optical image correction system. Background technique [0002] At present, during the test, if the image of the AOI machine used is blurred, it will seriously affect the test, which will cause the machine to report an error during the power-on self-test, making it unusable. [0003] Such as figure 1 As shown, the working principle of the AOI machine is as follows. The SAKI machine 10 mainly includes a linear camera 101, a reflection unit 102, a light source unit 103, and a prism 104 arranged in the light source unit 103. The light emitted by the light source unit 103 is printed After the circuit board 20 passes through the prism 104, the reflection unit 102, and the linear camera 101 in sequence, the image can be obtained after refraction. Since the camera image has multiple refractions, if the image is formed without correction, the image will be distorted. If necessary If it i...
