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 a handheld 3D information collecting device and method, and the device comprises an image collecting device which can be held by a hand and is used for collecting a group of images of a target object through relative movement; and a sensor which is used for measuring the moving linear distance of the image acquisition device during two times of acquisition. When a user movesthe image acquisition device, an alarm is given to the user when the moving linear distance does not meet the condition; or the moving distance of the user is prompted in real time. The invention provides a method for improving the synthesis effect and shortening the synthesis time by limiting the moving distance of a camera for two times.

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...
