Problems solved by technology
[0003] In the related art, the camera used in the non-contact optical active 3D imaging device is an infrared camera. Although it can filter out visible light, its half-bandwidth (generally above 30nm) is still relatively small compared to the half-bandwidth of emitted light (generally within 1nm). It is very wide, so in the outdoor situation, there will still be a lot of stray interference light entering the camera and causing imaging failure

The invention relates to the technical field of 3D detection, and discloses a three-dimensional camera and 3D detection equipment. The three-dimensional camera comprises a lens element, a photosensitive element and a filtering element, wherein the half bandwidth of the filtering element is greater than 0 nm and less than 30 nm, and the filtering element, the lens element and the photosensitive element are arranged in sequence; or the lens element, the filtering element and the photosensitive element are arranged in sequence. According to the three-dimensional camera, the light filtering element is arranged, the half bandwidth of the light filtering element is larger than 0 nm and smaller than 30 nm; the light filtering element, the lens element and the photosensitive element are sequentially arranged, or the lens element, the light filtering element and the photosensitive element are sequentially arranged, so that natural light interference is reduced, the signal-to-noise ratio is greatly increased, and the imaging quality of the three-dimensional camera is improved.
Description
technical field [0001] The present invention generally relates to the technical field of 3D detection, and in particular to a 3D camera and 3D detection equipment. Background technique [0002] Traditional 2D imaging devices, such as cameras, can only obtain plane information of objects; while 3D imaging devices can also obtain depth information of objects to build a three-dimensional 3D model, so 3D imaging devices are widely used in industrial measurement, part modeling , medical diagnosis, security monitoring, machine vision, biometrics, augmented reality AR, virtual reality VR and other fields, has great application value. [0003] In the related art, the camera used in the non-contact optical active 3D imaging device is an infrared camera. Although it can filter out visible light, its half-bandwidth (generally above 30nm) is still relatively small compared to the half-bandwidth of emitted light (generally within 1nm). It is very wide, so in the outdoor situation, there...
