Abstract
The invention provides a kind of method of three-dimensional on-site data gathering, comprise the following steps：Three-dimensional laser scanner is set up at the scene, and colour point clouds are obtained by the camera built in three-dimensional laser scanner, three-dimensional scenic is reduced into；The top view at scene is obtained by cloud data, and measurement data is output in modeling, so as to obtain the sketch at scene；Sketch is imported into Perspective Analysis system generation simulation scene, comprehensive online viewing is carried out to scene with the first visual angle in the Perspective Analysis system.The present invention can carry out scene reproduction by above-mentioned technical proposal to the scene of the accident, help personnel in charge of the case to be fully understood by the details at scene in kind；In addition using Z+F Laser Control criminal investigations version module cloud data can also can be used to carry out bullet trajectory analysis, by the various data of acquisition, to carry out crime deduction, to prove the reliability of various reasonings.
Description
Technical field
3-D scanning field of the present invention, more particularly to a kind of method of three-dimensional on-site data gathering.
Background technology
We are frequently seen among movie and television play, and the police reduce scene of a crime, analysis case by various high-tech means
Feelings, so as to quickly catch offender.So, the police are to employ what black science and technology, carry out scene of a crime reproductionWe are together
Go to take off.
Scene of a crime includes a series of information, including victim position, victim's posture, bloodstain posture, bullet shell case
The information such as position, currently for the record at crime incident scene, be still in photo, video, tape measure and cartographical sketching mainly
Existing original appearance.
Conventional method drawback：
1st, it is difficult to record these complicated information using traditional method, not only needs the substantial amounts of record time, and
Easily there is the incomplete situation of information, many times often carry out scene of a crime record by the working experience of personnel in charge of the case,
So as to delay the best opportunity solved a case.
2nd, the information error that traditional approach is obtained is larger, some parameter informations can only be showed roughly, simultaneously because various sides
The data that formula is obtained are problematic to integrate into together, it is necessary to check each repeatedly when later stage personnel in charge of the case analysis crime incident is live
Plant the data such as video, picture, sketch.
3rd, no clue is sometimes scouted by scene, and the initial data of scene of a crime repeatedly divided by the later stage
Analysis just can obtain some clues and traces, so this is just with greater need for there is high-tech instrument that scene of a crime can be digitized to guarantor
Deposit, so that the later stage can therefrom obtain more multi thread.
The content of the invention
The invention provides a kind of method of three-dimensional on-site data gathering, comprise the following steps：

The top view at scene is obtained by cloud data, and measurement data is output in modeling, so as to be showed
The sketch of field；
Sketch is imported into Perspective Analysis system generation simulation scene, with the first visual angle to scene in the Perspective Analysis system
Carry out comprehensive online viewing.
The method of above-mentioned three-dimensional on-site data gathering, wherein, methods described also includes：
Live part is taken multiple scan and found a view, to improve the point cloud definition and precision that collect.
The method of above-mentioned three-dimensional on-site data gathering, wherein, using Z+F IMAGER 5010C three-dimensional laser scanners
Scene is scanned.
The method of above-mentioned three-dimensional on-site data gathering, wherein, sketch is imported into Perspective Analysis system generation simulation scene,
So as to obtain the RGB point cloud that splicing is completed, plane line layout figure and the victim position at scene are obtained by the point cloud of splicing
Put, victim's posture, bullet shell case positional information.
The method of above-mentioned three-dimensional on-site data gathering, wherein, sketch is imported to Z+F pretreatment software Laser
Control criminal investigations version module carries out data processing, to generate simulation scene.
The method of above-mentioned three-dimensional on-site data gathering, wherein, the top view at scene is obtained by cloud data, and will survey
Data output is measured into AUTO-CAD modelings.
