Embodiment 1

[0051] In order to solve the above technical problems, an embodiment of the present invention provides a 3D information acquisition / measurement device. Such as figure 1 As shown, it specifically includes: a track 101, an image acquisition device 201, an image processing device 100, a mechanical moving device 102, the image acquisition device 201 is installed on the mechanical moving device 102, and the mechanical moving device 102 can move along the track 101, so that the image acquisition The collection area of ​​the device 201 is constantly changing, forming multiple collection areas in different spatial positions over a period of time, forming a collection matrix, but at a certain moment there is only one collection area, so the collection matrix is ​​"virtual". Since the image acquisition device 201 is generally composed of cameras, it is also called a virtual camera matrix. However, the image acquisition device 201 can also be a video camera, CCD, CMOS, camera, mobile p...

Embodiment 2

[0083] In addition to the above-mentioned way of forming a virtual matrix through orbital movement, it can also be realized through camera rotation.

[0084] Please refer to image 3 with Figure 4 , the 3D information acquisition device includes: an image acquisition device 201, which is used to collect a group of images of the target object through the relative motion of the acquisition area of ​​the image acquisition device 201 and the target object; The area and the target object generate relative motion; the acquisition area moving device 400 is a rotating shaft device in the rotating device, so that the image acquisition device 201 rotates along a central axis;

[0085] The image acquisition device 201 is a camera, the camera is fixedly installed on the camera holder on the revolving seat, the revolving seat is connected with a rotating shaft, the rotating shaft is controlled by the rotating shaft driving device, and the rotating shaft driving device and the camera are ...

Embodiment 3

[0091] The virtual matrix can be a one-dimensional matrix or a two-dimensional matrix. When forming a two-dimensional matrix, it can be realized by setting multiple tracks (but not limited to this).

[0092] Please refer to Figure 5 , specifically includes: a first track 1011 , a second track 1012 , a first image acquisition unit 2011 , a second image acquisition unit 2012 , and an image processing device 100 . It also includes a servo motor, which can drive the first image acquisition unit 2011 and the second image acquisition unit 2012 to move on the corresponding first track 1011 and second track 1012 . When the above two collection units collect photos that can be used for 3D synthesis on the corresponding tracks, their positions are the matrix points. A two-dimensional matrix of points arranged in space can be formed by the two tracks, that is, a two-dimensional virtual matrix can be formed.

[0093] Of course, forming a two-dimensional matrix is ​​not limited to pass...

Abstract

The invention provides a measuring device based on a virtual matrix and a related device, wherein, the measuring device comprises an image acquisition device, which is used for providing an acquisition area and acquiring corresponding images; a collection-area move device, wherein the image acquisition device is used for driving the acquisition area of the image acquisition device to move to different positions to form other acquisition areas, so that a virtual image acquisition matrix composed of a plurality of acquisition areas is formed in a certain time space, and the image acquisition device obtains images of different directions of the target object from the plurality of acquisition areas; the image acquisition device is used for driving the acquisition areas of the image acquisitiondevice to move to different positions to form other acquisition areas; an image processing device that processes the image obtained by the virtual image acquisition matrix to obtain 3D information ofthe object; a measuring device measuring a geometric size of a target object according to 3D information of the target object. For the first time, the problem of low resolution of multi-camera matrixacquisition due to the camera volume is noticed and put forward. It is proposed that the resolution can reach pixel level by forming virtual camera matrix in a certain period of time to improve the acquisition resolution.

Description

technical field [0001] The invention relates to the technical field of 3D measurement of objects, in particular to the technical field of 3D acquisition of objects by using pictures and measurement of geometric dimensions such as length. Background technique [0002] At present, 3D acquisition / measurement equipment is mainly aimed at a specific object. After the object is determined, multiple cameras simultaneously collect multiple photos of the object to synthesize a 3D image of the object, and use the 3D point cloud data to measure the length and contour of the object. [0003] However, the use of multiple cameras makes the entire device bulky. And because the size of the lens and body of the current camera itself is fixed, the distance between adjacent cameras has a limit value (determined by the geometric size of the camera). In this case, the acquisition intervals of multiple cameras are relatively large, so that the final 3D point cloud or image synthesis effect is po...
