Description

technical field [0001] The invention relates to the technical field of laser three-dimensional imaging, in particular to a range-gated super-resolution three-dimensional imaging device and method. Background technique [0002] Aiming at the short range (such as structured light imaging, binocular stereo vision imaging) and low spatial resolution (such as flash lidar imaging) of traditional 3D imaging technology, people have developed range-gated 3D imaging technology. The range-gated 3D imaging technology is a new type of 3D imaging technology. It uses the range-gated imaging technology to obtain target spatial slice images, and based on this, inverts the 3D spatial information of the target. It has high spatial resolution (the number of pixels can be greater than 1000 ×1000), long range (several kilometers), fog-breaking, rain-snow imaging and other characteristics, it has a wide range of applications in the fields of robot vision, virtual reality, target reconnaissance, sp...

Problems solved by technology

However, in the inversion of distance information, the dynamic range of the gray ratio between adjacent slices is small, which makes it sensitive to background noise disturbance. A small change in the gray ratio will cause a large distance inversion error, thereby reducing the The range resolution is affected, which affects its application in the fields of low-contrast target detection, long-range identification, reverse engineering, and spacecraft soft landing.
