Problems solved by technology

However, in practical applications, it is found that unless there is an accurate angle measurement device, the user is not sensitive to the angle, and it is difficult to determine the angle accurately; the size of the target object is difficult to accurately determine, especially in some applications where the target object needs to be replaced frequently. A lot of extra work is required, and professional equipment is required to accurately measure irregular targets
Measurement errors lead to camera position setting errors, which will affect the speed and effect of acquisition and synthesis; the accuracy and speed need to be further improved

Abstract

The present invention provides a 3D intelligent vision device, comprising a rotating device for driving the acquisition area of ​​the image acquisition device to generate relative motion with the target object; the image acquisition device is used for collecting a group of images of the target object through the above-mentioned relative motion; The optical axis of the collection device and the rotation plane of the rotation device have an included angle γ. For the first time, it is proposed to collect the target image by rotating the camera optical axis and the turntable at a certain angle rather than parallel, so as to realize 3D synthesis and modeling without rotating around the target, which improves the adaptability of the scene.

Description

technical field [0001] The invention relates to the technical field of shape measurement, in particular to the technical field of 3D shape measurement. Background technique [0002] At present, when using a visual method for 3D acquisition and measurement, the camera is usually rotated relative to the target object, or multiple cameras are set around the target object for simultaneous acquisition. For example, the Digital Emily project of the University of Southern California uses a spherical bracket, and hundreds of cameras are fixed at different positions and angles on the bracket, so as to realize 3D acquisition and modeling of the human body. However, in either way, the distance between the camera and the target object needs to be short, at least within the range that can be arranged, so that the camera can collect images of the target object at different positions. [0003] However, in some applications, it is not possible to collect images around the target object. F...
