3D intelligent visual equipment

Abstract

The invention provides 3D intelligent visual equipment, which comprises a rotating device and an image acquisition device, wherein the rotating device is used for driving an acquisition region of theimage acquisition device to move relative to a target object; the image acquisition device is used for acquiring a group of images of the target object by means of the relative movement; and an optical axis of the image acquisition device and the rotating plane of the rotating device form an included angle gamma. The 3D intelligent visual equipment proposes for the first time that a camera opticalaxis and a rotary disc rotate at a certain included angle rather than in parallel to acquire images of the target object, thus 3D synthesis and modeling are realized without rotating around the target object, and the adaptability of a scene is improved.

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...

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
