Multi-device calibration process automatic guiding method and system based on calibration board identification

Abstract

The invention relates to the technical field of calibration, in particular to a multi-device calibration process automatic guiding method based on calibration plate recognition, which comprises the following steps: acquiring an image of at least one camera in real time, and acquiring a calibration plate in the image; analyzing the position and posture of the calibration plate in the camera image in real time; mapping the position and the attitude to a discretized multi-dimensional position and attitude space, and determining corresponding space cells; maintaining a coverage state table for recording the acquisition state of each space cell in the multi-dimensional position attitude space; according to the coverage state table, judging whether a space cell corresponding to the current position and posture is acquired or not; if not, automatically capturing and storing a current image; by integrating real-time image analysis, an intelligent guiding strategy and a coverage rate monitoring mechanism, the problems that in a traditional calibration process, operation subjectivity is high, efficiency is low, and data quality is difficult to guarantee are remarkably solved.
