Image composite debugging method and system for laser radar echo signal simulation device

Abstract

The invention provides a laser radar echo signal simulation device image composite debugging method and system. The method comprises the following steps: S1, carrying out region segmentation and numbering on a light modulation device; s2, setting a debugging calibration device according to the working wave band of the illumination laser source; s3, debugging the imaging position of the central segmentation area and the imaging of the adjacent segmentation areas; and S4, judging whether the four adjacent imaging areas meet a preset standard or not, if so, not repeatedly debugging, otherwise, repeatedly debugging until all the areas meet the preset standard. According to the invention, the problems that each imaging area of the light modulator is not coaxial with the corresponding micro-lens array and the spatial compound precision of the image is greatly reduced due to errors between the actual processing position and theory of each micro-lens array of the image compound module are solved, the simulation quality of the laser radar echo signal is improved, and the simulation precision of the laser radar echo signal is improved. And the requirement of the system on imaging quality is met.

Description

technical field [0001] The invention relates to the field of optics, in particular, to a debugging method for a three-dimensional image simulation device, and more particularly, to a method and system for composite image debugging of a laser radar echo signal simulation device. Background technique [0002] Lidar is based on laser ranging technology. It emits laser pulse signals to illuminate the target and receives echo signals from different effective optical sections of the target by the detector. According to the time of flight of the laser signal to each target point and return, an angle-angle is formed. - The distance image is then constructed to construct a three-dimensional image of the target. With the rapid development of lidar detection devices, lidar has gradually become the focus of domestic and foreign military and civil fields due to its high resolution, high detection accuracy, strong anti-interference and many other advantages. So far, lidar has been widely...

Problems solved by technology

However, this invention does not solve the problem that due to the error between the actual processing position of each microlens array of the image composite module and the theory, the imaging area of ​​the light modulation device is not in the same axis as the corresponding microlens array, and the spatial composite accuracy of the image will be greatly reduced.
