CMOS sensor-based embedded correction system and correction method thereof

Abstract

The invention discloses a CMOS sensor-based embedded correction system and a correction method thereof. The CMOS sensor-based embedded correction system comprises a correction instrument and a control box, wherein the correction instrument comprises a bracket, an annular light source module, a shell, an STM32 main operation controller, a first Bluetooth module, a WiFi module, a CMOS image sensor, a state display and key control module and a TFT liquid crystal display module, wherein the annular light source module is fixed at the bottom of the bracket; the shell is fixed at the upper part of the bracket and located at the upper part of the annular light source module; the STM32 main operation controller, the first Bluetooth module and the WiFi module are arranged in the shell; the CMOS image sensor is arranged on the lower end surface of the shell; the state display and key control module is arranged on the upper end surface of the shell; and a motor drive module and a second Bluetooth module electrically connected with the motor drive module are arranged in the control box. Defect detection can be carried out on the edge of a strip before correction, so that the phenomenon of miscorrection is effectively prevented, the correction accuracy and reliability are improved and the CMOS sensor-based embedded correction system can adapt to comprehensive requirements of actual strip production.

Description

technical field [0001] The invention relates to an embedded deviation correction system and a deviation correction method based on a CMOS sensor. Background technique [0002] At present, visible light sensors, namely photoelectric sensors, are mainly used in domestic deviation correction control systems. Although there have been researches on infrared sensors and CCD sensors, there are not many applications in practice. The output of the visible light sensor is the switching signal of the offset, which can only indicate whether it is offset and the direction of the offset, which leads to the problems of vibration and low precision in the control; Poor, resulting in a relatively narrow scope of application; Finally, considering that there are inevitably certain defects at the edge of the actual industrial strip, if the strip is corrected for the edge defect, it will be counterproductive and even cause the strip to break. To sum up, the existing visible light sensor can no l...

The output of the visible light sensor is the switching signal of the offset, which can only indicate whether it is offset and the direction of the offset, which leads to the problems of vibration and low precision in the control; Poor, resulting in a relatively narrow scope of application; Finally, considering that there are inevitably certain defects at the edge of the actual industrial strip, if the strip is corrected for the edge defect, it will be counterproductive and even cause the strip to break

In summary, the existing visible light sensors can no longer meet the comprehensive requirements of actual strip production
