Positionable panoramic three-dimensional imaging system and positioning method thereof

Abstract

The invention belonging to the image acquisition system field provides a positionable panoramic three-dimensional imaging system and a positioning method thereof. The panoramic three-dimensional imaging system comprises camera shooting control equipment, at least two spherical camera shooting devices, and a data processing unit. Each spherical camera shooting device comprises at least three lens groups and an image sensor for receiving optical signals of the lens groups. The camera shooting control equipment is used for controlling all the spherical camera shooting devices to shoot target points at the same time; the two spherical camera devices form a first panorama and a second panorama respectively, the first panorama and the second panorama have an shooting overlapping area, and a target point is located in the shooting overlapping area. Therefore, problems that when a target positioning point and an imaging system are located on the two sides of a transparent object, laser or structured light can be reflected and refracted after passing through the surface of the transparent object and the intensity or direction of the laser or structured light is affected, and thus errors occur in measurement of the target positioning point, and the target point with the visible actual view cannot be located are solved.

Description

technical field [0001] The invention relates to an image acquisition system, in particular to a positionable panoramic three-dimensional imaging system and a positioning method. Background technique [0002] At present, in the field of forensic science / in case scene investigation / in the process of criminal photography, the main way to record and reproduce the court scene / case scene / crime scene is to use various camera systems (machines) to The shooting and recording of the real scene is a two-dimensional video image recording, and the data, information and traces are all two-dimensional. my country's public security and other law enforcement agencies urgently need to use 3D panoramic image technology in on-site inspection scenes to make up for the shortcomings of traditional criminal photography in 2D images, and improve the efficiency of case analysis, case study and judgment, and joint case investigation. [0003] The invention patent of the existing application publicati...

Problems solved by technology

[0005] However, the above-mentioned technical solution has the following problems: when the target positioning point and the imaging system are on both sides of a transparent object (such as glass), since the laser light or structured light passes through the surface of the transparent object, reflection and refraction will occur, affecting the intensity or intensity of the laser light or structured light. direction, resulting in an error in the measurement of the target positioning point, and it is impossible to locate the target point that is visible in the actual field of view, so it needs to be improved
