Problems solved by technology

[0004] However, when the acquisition device collects the image of the target object through the transparent plate, the quality of the collected image is not high and the definition is low. Using the above image for 3D synthesis affects the synthesis effect, and cannot be applied in the field of fine measurement and high image precision requirements

Embodiment 1

[0055] In order to solve the above technical problems, an embodiment of the present invention provides a device for acquiring / measuring 360° 3D information of an object. Such as figure 1 As shown, it specifically includes: an image acquisition device 1, a rotation device 2, a transparent carrying platform 3 installed on the rotation device 2, and a processing unit 4 connected to the image acquisition device 1, and the image acquisition device 1 is arranged on the transparent carrying platform 3- side.

[0056]During the use of the device, the target object is placed on the transparent carrying platform 3, the image acquisition device 1 passes through the transparent carrying platform 3 from the side of the transparent carrying platform 3, and collects the image of the target object, and the rotating device 2 rotates to drive the transparent carrying platform 3 Rotate, so that the target object also rotates correspondingly, and the rotating device 2 drives the carrying platfo...

Embodiment 2

[0095] In order to solve the above technical problems, an embodiment of the present invention also provides a device for acquiring 360° 3D information of an object. Specifically, it includes an image acquisition device 1 , a rotating device 2 , a transparent carrying platform 3 and a processing unit 4 .

[0096] The image acquisition device 1 is installed on the rotation device 2 and rotates with the rotation device 2; the rotation device 2 drives the image acquisition device 1 to rotate, and the transparent carrying platform 3 is fixed on one side of the image acquisition device 1, and the image acquisition unit and the processing unit 4 connect.

[0097] During the use of the device, the target object is set on the transparent carrying platform 3 and does not move. The image acquisition device 1 rotates with the rotating device 2 to collect images around the target object, and collects an image every time it rotates at a certain angle. A group of images of the target object...

Embodiment 3

[0103] In order to solve the above technical problems, an embodiment of the present invention also provides a device for acquiring 360° 3D information of an object. Concretely comprise: image acquisition device 1, rotation device 2, mesh structure carrying platform 31, image acquisition device 1 is installed on the rotation device 2, mesh structure carrying platform 31 is arranged on the collection direction of image acquisition device 1, rotation device 2 The image acquisition device 1 is driven to rotate around the mesh bearing platform and the target placed on the platform. The image acquisition device 1 collects multiple images of the target during the rotation process. The mesh structure can make the target object contact with the mesh structure. Most of the images of the area are captured by the image capture device 1 . At the same time, the mesh structure can also be used as a ruler to accurately measure the size of the target object.

[0104] The grid shape of the mes...

Abstract

The invention provides a 360° 3D measurement device for a target, which includes an image acquisition device for collecting a group of images of the target through its relative motion with the target; a rotating device for making the target and the image acquisition device produce a relative Movement; the transparent carrying platform is used to carry the target object, so that the image acquisition device can collect the image of the contact part between the target object and the transparent carrying platform; the reflective processing device is used to remove the noise effect caused by the reflection of the light-transmitting structure; the processing unit, It is used to obtain 3D information of the target object according to multiple images in the above group of images; the measuring unit is used to measure the geometric size of the target object according to the calibrated size and the 3D information of the target object. Through the method of removing the above-mentioned reflective noise after collecting the image, the measurement accuracy of the target object is improved.

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, the camera rotates around the object to collect multiple photos of the object, thereby synthesizing the 3D image of the object, and using the 3D point cloud data to measure the length and contour of the object. [0003] Ordinary 3D acquisition / measurement equipment, if the carrier plate used to place the target uses an ordinary platform, the target is placed on the platform for acquisition or measurement, and the contact area between the target and the platform is blocked by the platform, which means that the device cannot collect the contact. Image information for the region. Therefore, some e...
