Description

technical field [0001] The invention relates to the technical field of measurement data processing, in particular to a method and device for vectorizing measurement data of a unidirectional scanning sensor. Background technique [0002] In the measurement technology, the scanning sensor (i.e. scanning sensor) has a remarkable feature compared with the trigger sensor, which has a strong data acquisition ability, and can acquire a large amount of data on the surface of the measured feature in a short period of time, which is conducive to fine-tuning. It has the ability of continuous data acquisition, can realize uninterrupted measurement, and has a significant efficiency advantage for the measurement of continuous characteristics. Therefore, scanning sensors have good application prospects in fine evaluation, continuous feature measurement, and large-scale high-density measurement scenarios.

Problems solved by technology

[0003] Due to the consideration of price and technical difficulty, the more commonly used scanning sensor is the one-way scanning sensor, which can only realize one-way measurement, and the obtained measurement data is one-dimensional scalar data of the measured feature, reflecting the actual characteristics of the measured feature The comprehensive change of the profile relative to the theoretical profile, but cannot provide the specific change of the actual profile point of the measured feature in each direction relative to the theoretical profile point, that is, the single-direction scanning sensor can only provide the change of the measured feature, but cannot provide The direction of change of the measured feature

[0004] Based on this, the unidirectional scanning sensor can only be used for the measurement of simple features with a clear direction of change, or the measurement of features that do not pay attention to the direction of change, but cannot be used for the measurement of complex features, such as free curves, free Curved surfaces, etc., which severely limit the application scenarios of unidirectional scanning sensors, and it is difficult to give full play to their advantages

Moreover, since the unidirectional scanning sensor can only provide one-dimensional scalar information about the measured feature, but cannot provide its corresponding direction information, the contour obtained according to the one-dimensional scalar information has a large deviation compared with the actual contour, which affects subsequent processing. the accuracy of
