Problems solved by technology
The target intensity image acquired by traditional laser radar is the reflectance image of the target to a single laser emission wavelength, which can classify the target to a certain extent, but cannot accurately classify the target
[0003] In the existing color laser radar technology, patent CN201410217364.5 uses multiple detectors to receive, and the optical system is relatively complicated; patents CN201610199300.6 and CN201711432927.2 use CCD cameras only as detectors to obtain target color point cloud information and distance information It needs to be calculated and measured by other detectors
So far, no technology has been found that can achieve high-precision color imaging of the target with only one camera

The invention provides a color laser radar imaging device and method. A time-sharing distribution mode of different laser is adopted, delayed reception is realized by the same camera, a computer calculates and synthesizes an image, wherein the adopted laser is three-primary color laser of red, green, and blue. While the laser of a color is triggered, a signal generator generates a scanning signalsynchronously, target reflected echoes are also received in the order of triggering, and in a receiving process, an image intensifier is triggered in a delayed manner and is triggered for one more time.
Description
technical field [0001] The invention relates to the technical field of laser remote sensing, in particular to a color laser radar imaging device and an imaging method. Background technique [0002] Lidar is an active imaging technology that can acquire target intensity images and distance information around the clock, and is widely used in military, civilian and other fields. The target intensity image acquired by traditional laser radar is the reflectance image of the target to a single laser emission wavelength, which can classify the target to a certain extent, but cannot accurately classify the target. [0003] In the existing color laser radar technology, patent CN201410217364.5 uses multiple detectors to receive, and the optical system is relatively complicated; patents CN201610199300.6 and CN201711432927.2 use CCD cameras only as detectors to obtain target color point cloud information and distance information Calculation and measurement by other detectors are then r...
