Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0049] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of a range-gated super-resolution three-dimensional imaging distance map optimization display device provided by the present invention. Module 6 is displayed. Among them, the pulsed laser 1 emits laser pulses under the trigger of the first TTL trigger signal generated by the timing controller 3, illuminates the target, and forms a backward propagating echo signal; Under the triggering of the second TTL trigger signal generated, control the opening and closing of the gate, realize the acquisition of the target echo signal, and return the two-dimensional slice image obtained by the acquisition to the PC 4; the timing controller 3 is controlled...

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 ...
