Abstract

The invention relates to a system for measuring a stereo object, comprising a base, a plane scanning device arranged on the base, a first light source emitting device, a second light source emitting device, an image capture device and a control device. The first light source emitting device, the second light source emitting device and the image capture device are connected to the plane scanning device, the control device is used for controlling the plane scanning device to do a planar motion, the first light source emitting device and the second light source emitting device respectively project light sources to the object alternatively and controlling the image capture device to capture images of the object; the first light source emitting device comprises a first light emitting element and a first lens, and the first light emitting element projects the first light source to the object; the second light source emitting device comprises a second light emitting element and a second lens, and the second light emitting element projects the second light source to the object; when the first or second light source is projected to the object and used for capturing a plurality of images ofthe object, the image capture device is located between the first light source emitting device and the second light source emitting device and comprises an induction chip module and a telecentric lens. According to the system for measuring the stereo object, dynamic acceleration and deceleration changes can be avoided.

Description

technical field [0001] The invention relates to a measuring system, especially a system for measuring three-dimensional objects. Background technique [0002] The measurement of a three-dimensional object usually requires an optical system including a "projection device" and an "imaging device". In short, the projection device projects structured light on a three-dimensional object to generate structured light and shadow, and the imaging device takes a picture of the three-dimensional object and simultaneously shoots the structured light and shadow of the three-dimensional object, thereby calculating the height of the three-dimensional object and using it 3D image display. [0003] It is becoming more and more common to apply 3D measurement technology to circuit board manufacturing inspection to improve production efficiency. In order to obtain 3D information, a current method is to project a periodic fringe pattern on the object to be measured. The periodic fringe phase ...
