3D projection scanning test device

Abstract

The invention discloses a 3D projection scanning test equipment, comprising a frame, a reference measurement platform, an X-axis mechanism, two parallel Y-axis mechanisms, a Z-axis mechanism and a 3D scanner, a reference measurement platform, a reference measurement platform and a Y-axis mechanism Both are set on the frame, the X-axis mechanism is slidingly set on two parallel Y-axis mechanisms, the Z-axis mechanism is slidingly set on the X-axis mechanism, and the 3D scanner is set on the Z-axis mechanism. The 3D scanner includes a 3D scanning system and an industrial vision module. And the screw rod, the screw rod is connected to the output end of the servo motor of the Z-axis mechanism, the 3D scanning system is connected to the screw rod, and the 3D scanning system and the industrial vision module correspond to the benchmark measurement platform. Place the required product on the reference measurement platform, start the equipment to make the X-axis mechanism, Y-axis mechanism and Z-axis mechanism linkage, the 3D scanning system and industrial vision module on the Z-axis mechanism will measure the product, and the measured data will be fed back to The control system performs the export at the end.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a 3D projection scanning testing equipment. Background technique [0002] The earliest appeared was the contact measurement method, represented by the three-dimensional coordinate measuring machine. Although the accuracy reached the micron level (0.5mm), its application field was limited due to the shortcomings of huge volume, high cost and inability to measure soft objects. [0003] So there are non-contact measurement methods, which are mainly divided into two categories: [0004] One is the passive method, which does not require a specific light source and relies entirely on the natural light conditions of the object for scanning. Binocular technology is often used, but the accuracy is low, and only objects with geometric features can be scanned, which cannot meet the requirements of many fields. ; [0005] The other is the active method, which is to project specif...

Problems solved by technology

[0004] One is the passive method, which does not require a specific light source and relies entirely on the natural light conditions of the object for scanning. Binocular technology is often used, but the accuracy is low, and only objects with geometric features can be scanned, which cannot meet the requirements of many fields. ;

[0005] The other is the active method, which is to project specific light to the object, which represents the technology of laser line scanning, which has relatively high precision, but because only one light can be projected at a time, the scanning speed is slow

In addition, because the laser will cause damage to living organisms and more precious objects, it cannot be applied to certain specific fields.
