Abstract

One aspect of the present invention provides a 3D acquisition control method, step 1: set the rotation speed of the servo motor: set the rotation speed of the servo motor according to the number N of shots taken by the image acquisition device and the shot interval Δt; step 2: set the rotation speed of the servo motor Motor acceleration time t up ; Step 3: Start the servo motor to drive the image acquisition device to rotate; Step 4: The image acquisition device starts to collect the image of the target object. For the first time, it is proposed to improve the synthesis speed and synthesis accuracy by optimizing the camera rotation control algorithm.

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...
