Abstract

The invention discloses an object 3D size simple measurement method based on binocular stereo vision. A handheld 3D scanner is included. The handheld 3D scanner comprises a casing and an electronic control device installed in the casing. The electronic control device comprises a power supply module, a processor which carries out central control, first and second infrared cameras connected to the processor, an infrared structure light generator, and a man-machine interface. The first and second infrared cameras are arranged at the front part of the casing, horizontally arranged at intervals and used for collecting infrared visual information. The infrared structure light generator is connected with the processor, arranged between the first and second infrared cameras and used for emitting net-shaped active infrared light. The man-machine interface is connected with the processor. The man-machine interface comprises buttons and an LCD and is used for command input and information display. The processor is internally provided with an environment depth calculation algorithm and an object 3D size measurement algorithm. A shooting angle can be intelligently identified by the object 3D size measurement algorithm, the 3D size of an object is measured from multiple angles, and the convenience and reliability of use are improved.

Description

technical field [0001] The invention relates to a simple method for measuring the three-dimensional size of an object based on binocular stereo vision, belonging to the field of measuring equipment. Background technique [0002] The geometric size information of objects is very important for transportation and storage, and can be used to solve the optimization problem of cargo stacking. In the actual operation process, in order to meet the scanning shooting requirements, the operator needs to select the angle around the goods, or move the goods to obtain the required shooting angle, which brings great difficulties to the actual operation. Contents of the invention [0003] The object of the present invention is to provide a simple method for measuring the three-dimensional size of an object based on binocular stereo vision. This solution uses stereo vision technology to quickly measure the three-dimensional size of the product, adopts an intelligent recognition algorithm,...
