Abstract

The invention discloses an automobile detection non-common-field-of-view camera global calibration system and method based on a surface light field, and aims to solve the problem of automobile detection non-common-field-of-view camera global calibration based on the surface light field. The automobile detection common-field-of-view-free camera global calibration system based on the surface light field is mainly composed of a laser plate box (1), a laser plate box support (2), a left camera (3), a left camera support (4), a right camera (5), a right camera support (6), a surface laser (7) and acylindrical target (8). The invention discloses an automobile detection non-common-view-field camera global calibration method based on a surface light field. The method comprises the steps of acquiring an image, resolving a homography matrix converted from the cylindrical target (8) to a coordinate system of the left camera (3) according to the image acquired by the left camera (3), and the like. The automobile detection non-common-field-of-view camera global calibration system and method based on the surface light field are simple in structure and reliable in performance.

Description

technical field

[0001] The invention relates to a measurement device and a measurement method in the field of vehicle detection, more specifically, it is a system and method for global calibration of a vehicle detection non-common field of view camera based on a surface light field. Background technique

[0002] Automobile inspection is one of the important research contents of automobile passability and driving safety inspection, and visual inspection has gradually become a key technology to improve the efficiency and accuracy of automobile inspection due to its advantages of non-contact, low cost and high precision in recent years. Machine vision can be used to detect vehicle wheel alignment parameters, vehicle wheelbase difference detection, vehicle shape detection, multi-axle axle deflection detection, vehicle model identification, overloading and many other fields. However, currently commonly used visual inspection methods, such as single-camera systems, cannot meet the...
