Abstract

The invention discloses a 3D structured light measurement method and device. The 3D structured light measurement method comprises the following steps: acquiring a first speckle pattern and a second speckle pattern; according to a definition parameter and a brightness parameter, synthesizing a first light spot at a preset position in the first speckle pattern and a second light spot at a preset position in the second speckle pattern to obtain a third light spot at a preset position in a third speckle pattern; and obtaining the position information of the target object by using a third light spot in the third speckle pattern. According to the invention, the definition parameter and the brightness parameter serve as synthesis processing rules, the first light spot and the second light spot are synthesized to obtain the third light spot, the spatial position information of the target object is obtained according to the third light spot, interference of natural light on the spatial position information is avoided, and accurate spatial position information can be obtained.

Description

technical field [0001] The present invention generally relates to the technical field of 3D structured light, and in particular to a method and device for measuring 3D structured light. Background technique [0002] With the development of science and technology, traditional 2D measurement methods are difficult to meet the requirements of spatial position information and high measurement accuracy. Coupled with the continuous rise of the artificial intelligence industry in modern society, the requirements for real-time and remoteness of measurement technology are put forward, and the defects of traditional 2D measurement are becoming more and more prominent. 3D measurement technology, especially 3D structured light technology, is widely used due to its advantages of high precision, low cost, and low power consumption. [0003] In the related art, the device using 3D structured light technology, in the natural strong light environment, the light spot emitted by the transmitte...
