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 invention provides high-speed acquisition and measurement equipment for 3D information of a target object. The high-speed acquisition and measurement equipment comprises an image acquisition device, a rotating device and a background plate, wherein the rotating device is used for driving the image acquisition device to rotate and driving the background plate to rotate; the background plate andthe image acquisition device are kept oppositely arranged in the rotating process, so that the background plate becomes a background pattern of an image acquired by means of the image acquisition device during acquisition; and the background plate is required to meet preset conditions. The high-speed acquisition and measurement equipment proposes a mode that the background plate rotates along with a camera to be added for the first time to improve the synthesis speed and the synthesis precision at the same time. By optimizing the size of the background plate, the synthesis speed and the synthesis precision can be improved at the same time while the rotation burden is reduced.

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] When performing 3D measurement, 3D information needs to be collected first. The currently commonly used methods include using machine vision to collect pictures of objects from different angles, and matching and splicing these pictures to form a 3D model. When collecting pictures from different angles, multiple cameras can be set at different angles of the object to be tested, and pictures can also be collected from different angles by rotating a single or multiple cameras. But no matter which of these two methods, it involves the problems of synthesis speed and synthesis accuracy. To some extent, the synthesis speed and synthesis accuracy are a pair of contradictions. The increase of the synthesis speed will lead to the decrease of the final 3D synthesis accuracy; to improve the 3D synthesis a...
