Three-dimension imaging device, system and method

Abstract

The invention provides a three-dimension imaging device, system and method. The method comprises the steps of obtaining images shot by two shooting units of one shooting module, recognizing base point light spot images corresponding to base point light spots from injection light spot pattern images according to preset base point light spot judging rules, using the base point light spot images as reference and the preset measuring light spot determining rules to determine all measuring light spot images, identifying all the light spot images, determining the relevance of the same measuring light spot in measuring light spot images of different images, calculating the detecting distance of the base point light spots and the detecting distance of all the measuring light spots according to all the image base point light spot images and all the measuring light spot images, and constructing a three-dimension image according to the detecting distance of the base point light spots and the detecting distance of all the measuring light spots. The invention further provides a three-dimension imagining device and a three-dimension imaging system, and three-dimension images can be constructed quickly and accurately.

Description

technical field [0001] The present invention relates to a three-dimensional imaging device, system and method, in particular to a three-dimensional imaging device, system and method combining laser spot with camera. Background technique [0002] At present, the 3D imaging technology is widely used in various electronic devices, such as 3D photography, somatosensory game control, somatosensory remote control, or precision industrial manufacturing. [0003] A general three-dimensional imaging technology is to use two camera units with different camera angles to capture an image at the same time, and combine the two images into a three-dimensional image. However, in this technology, how to determine all the same points in the image obtained by the camera unit a and the image obtained by the camera unit b is a difficult problem. Therefore, it is basically necessary to manually carry out the same point correlation. [0004] Another method is to use TOF (Time-of-flight) technolo...

Problems solved by technology

When the inventor thinks that there are many deficiencies in this optical encoding technology, for example: (1) to store images of light spots at different distances, when the number of light spots is large and the distance requirement is very fine, a lot of images will be stored; (2) when the light spots When the number is large, it is very difficult to ensure that the projected image of any spot at any different distance is different
