Image Acquisition and Processing for Laser Autocollimator

Abstract:

For the needs of laser autocollimator in image acquisition and processing, designed the hardware circuit based on FPGA and DSP as the control core, detailed the system hardware composition. Image sensor initialization and configuration were elaborated, cached the image data by double buffering technique. By reading the cache data, pretreatment, spot extraction, calculating barycentric coordinates and data fitting, the high precision of angle measurement was obtained. The system design is reasonable, the hardware circuit is reliable, and the video capture image is clear. The functionality of image acquisition and processing is achieved.
