Problems solved by technology

Because passive 3D imaging has a great dependence on the prior knowledge of illumination and object shape, it has great limitations in some occasions.
Moreover, passive 3D imaging will also lose information due to different viewing angles and occlusion of objects, which will have a negative impact on the accuracy of its restoration.

Abstract

The invention provides an actively imaging laser camera and imaging method thereof. The actively imaging laser camera includes a laser generator, a light sensor and a control chip, the laser generator and the light sensor are connected with the control chip, the imaging method includes the following steps: 1. collecting a three-dimensional spherical coordinate (phi, theta, r) of an object relative to a focal point of the camera and 2. performing image conversion. The actively imaging laser camera and the imaging method thereof has the advantage that in the same scene, only one image needs to shot in one position, so that three-dimensional information of a spatial point can be obtained. The actively driving laser camera and imaging method thereof have no dependency on priori knowledge of the illumination and object shape, information is not lost due to difference of a three-dimensional imaging angle of view and shielding of the object, the recovery precision is high.

Description

technical field [0001] The present invention relates to special equipment for photography, relates to the combination of camera and electronic flash equipment, especially an imaging method of an active imaging laser camera head. Background technique [0002] Traditional 3D imaging can be called passive 3D imaging, which is modeled on the way humans use binocular cues to perceive distance. It needs to take two or more images at different positions in the same scene, and calculate the parallax of the spatial points in the two images. , to obtain the three-dimensional information of the spatial point. Because passive 3D imaging has a great dependence on the prior knowledge of illumination and object shape, it has great limitations in some occasions. Moreover, passive 3D imaging will also lose information due to different viewing angles and occlusion of objects, which will have a negative impact on the accuracy of its restoration. Contents of the invention [0003] Aiming at...
