Abstract

The invention discloses an optimized display device and an optimized display method for a range-gating super-resolution three-dimensional imaging distance map. The device comprises a pulse laser device, a gating and imaging apparatus, a time sequence controller, a PC (personal computer), a three-dimensional imaging module and an optimized display module. Based on the device, the invention discloses the optimized display method for the range-gating super-resolution three-dimensional imaging distance map, wherein a slice image with low bit depth is replaced with a slice image with high bit depth to obtain a three-dimensional grey distance map with high bit depth, and the distance resolution is improved; in order to vividly show more details, during pseudo-color processing of the distance map with high bit depth, the distance map with high bit depth is linearly normalized to 256-level grey level, and equal-density pseudo-color coding is performed. On the basis of improving the three-dimensional imaging distance resolution to the greatest extent, equal-density pseudo-color coding display of the range-gating super-resolution three-dimensional imaging technology is realized.

Description

technical field

[0001] The invention relates to the technical field of three-dimensional imaging, in particular to a device and method for optimizing and displaying distance maps of range-gated super-resolution three-dimensional imaging. Background technique

[0002] Range-gated super-resolution 3D imaging technology is widely used in terrain mapping, remote sensing, intelligent monitoring, underwater imaging and It has important application prospects in fields such as automatic obstacle avoidance navigation.

[0003] There are two 3D reconstruction methods in range-gated super-resolution 3D imaging technology. One is in 2007, by Martin Laurenzis et al. from the German-French St. Louis Institute in "optical letter" Vol. The distance gating super-resolution 3D imaging method based on the trapezoidal space energy envelope proposed in ; the other is the triangular space energy envelope based on the triangular space energy envelope reported in 2012 by Wang Xinwei, Institute of ...
