The invention discloses an image splicing method based on grating scale encoder positioning and weight fusion, and belongs to the field of image processing. The method comprises a system calibration stage and a real-time splicing stage, wherein the system calibration stage comprises calibration data acquisition, camera pose calculation and mapping relation establishment; the real-time splicing stage comprises workpiece image acquisition, real-time coordinate mapping, image relative displacement calculation, weight accumulation to a global buffer area, judgment of processing states of all sub-images and normalized fusion output. The splicing process is completely independent of matching of image features, that is, the image content is not required, the splicing speed is high, and the real-time performance is high. A direct mapping relation between encoder readings and camera world poses is established through global motion calibration, and each sub-image is positioned based on absolute coordinates. No accumulated error exists, and the precision of the global image can be ensured. As long as the mechanical structure is kept stable, one-time calibration can be achieved, and then the calibration data can be used for multiple times of jigsaw puzzle in the follow-up process.

The application relates to a coaxial connector dynamic assembly control method based on time domain reflection feedback. The method comprises the following steps: constructing a target impedance model; calibrating an assembly zero point; driving a shielding shell to quickly approach a preset safe depth; performing a fine regulation cycle of step-by-step pressing and impedance detection to obtain an instantaneous impedance characteristic value; and stopping pressing and fixing the position of the shielding shell when the instantaneous impedance characteristic value falls within the target impedance parameter range. The application controls the mechanical assembly depth through the electrical performance feedback closed loop, effectively eliminates the influence of the manufacturing tolerance on the characteristic impedance, solves the impedance dispersion problem in the assembly of special-shaped terminals, and significantly improves the high-frequency performance consistency and assembly yield of the connector.
