Problems solved by technology

However, due to the large volume and complex processing of the existing three-dimensional calibration objects, it is difficult to achieve on-site calibration with high practical requirements; at the same time, the existing three-plane calibration targets can only obtain three-dimensional data points in three vertical coordinate planes, and cannot obtain spatial coordinates 3D data points of general location in intrasystem space

Abstract

The invention discloses a camera three-dimensional truss calibrating target for an automotive visual detection system. The camera three-dimensional truss calibrating target for the automotive visual detection system aims at solving the problems that the existing three-dimensional calibrating object is large in size and complex in machining, cannot obtain three-dimensional data points of spatial general positions in a space coordinate system and is difficult to achieve site calibrating which is high in requirement for practicability. The camera three-dimensional truss calibrating target for the automotive visual detection system is mainly formed by target balls (1) and connecting rods (2). The camera three-dimensional truss calibrating target for the automotive visual detection system has the advantages of being simple in structure, high in detection accuracy, small in accumulative error, complete in function, simple in operation, easy to install, strong in universality, low in cost and reliable in performance and satisfying an automotive detection industry requirement for visual detection of an automobile body.

Description

technical field [0001] The invention relates to an inspection device in the field of automobile industry, more specifically, it relates to a camera three-dimensional truss calibration target of an automobile visual inspection system. Background technique [0002] In order to ensure the safe driving of automobiles, it is one of the main inspection items in the field of automobile inspection to detect the overloading and size modification of automobiles reasonably and quickly, and to carry out visual measurement of various geometric dimensions and angles of automobiles. At present, the measurement of vehicle size and angle is mainly based on manual meter ruler measurement, which has low efficiency, poor accuracy and high labor intensity for staff. The use of machine vision measurement technology for non-contact detection of automotive geometric parameters is expected to solve the above technical bottlenecks due to its characteristics of fast, accurate and high reliability. Si...
