Embodiment Construction

[0080] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0081] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The invention discloses an image processing system, apparatus and method for a displacement sensor. The system comprises a linear array light-sensitive chip and an FPGA processing chip, wherein the linear array light-sensitive chip is connected with an FPGA processing chip; and the FPGA processing chip comprises a receiving module and an image processing module, wherein the receiving module is used for receiving image signals from the linear array light-sensitive chip, and the image processing module is used for filtering the image signals received by the receiving module, determining the position of the center point of an image contour according to the filtered image signals and determining a relative displacement value. According to the system provided by the invention, real-time image processing is completely realized by the FPGA; the relative displacement value is determined based on the center point of the image contour; and therefore, the use of large-sized equipment can be avoided, and installation and use can be facilitated, and the method used in image processing can be effectively applicable to the linear array sensing chip, and thus, the precision of displacement sensing can be ensured, the complexity, cost and energy consumption of the system can be reduced, the hardware requirement of the system can be lowered, and real-time performance can be ensured.

Description

technical field [0001] The present invention relates to the technical field of image acquisition and processing, and in particular, relates to an image processing system, device and method for a displacement sensor. Background technique [0002] Optical sensors are instruments that measure based on optical principles. This type of sensor has many advantages, such as non-contact and non-destructive measurement, almost uninterrupted measurement, high-speed transmission, and telemetry and remote control. [0003] Optical sensors include many types, among which the non-contact laser triangular displacement sensor is a CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) or CCD (Charge-coupled Device, charge-coupled device) sensor that uses a laser as a light source A precision measuring instrument as a receiver. This kind of sensor can accurately measure the position, displacement and other changes of the measured object without contact, and c...
