Problems solved by technology

[0002] The pulsed 3D lidar based on the time-of-flight method is widely used in the fields of 3D modeling and environmental perception due to the use of pulsed lasers as the light source, which has the characteristics of long measurement distance, high frequency, and low power consumption. The horizontal resolution of the laser detection part in the system is low, and the image sensor device has a high horizontal resolution for obtaining two-dimensional images, but it does not have the ability of direct three-dimensional imaging
In the prior art, the lidar point cloud data and image data are usually obtained separately, and then the two are fused. High requirements and complex algorithms

Abstract

The invention relates to a laser radar point cloud and image fusion-type detection system, which comprises a laser emitting component, a spectroscope, a beam deflection component, a first laser detection component, a coaxial optical receiving component, a second laser detection component and an image detection component. Through adopting the coaxial optical receiving component, third returning light received by the second laser detection component and fourth returning light received by the image detection component are both from first returning light comprising reflection light generated when the second laser illuminates the target object and reflection light generated when a background lighting source illuminates the target object, or, when the system is adopted, the laser radar point cloud information and the image information can be acquired synchronously, subsequent fusion between the laser radar point cloud information and the image information is facilitated, and the calculation complexity is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of laser radar, in particular to a laser radar point cloud and image fusion detection system. Background technique [0002] The pulsed 3D lidar based on the time-of-flight method is widely used in the fields of 3D modeling and environmental perception due to the use of pulsed lasers as the light source, which has the characteristics of long measurement distance, high frequency, and low power consumption. The horizontal resolution of the laser detection part in the laser detection device is low, and the image sensor device does not have the ability of direct three-dimensional imaging, although the horizontal resolution is high for obtaining two-dimensional images. In the prior art, the lidar point cloud data and image data are usually obtained separately, and then the two are fused. The requirements are high and the algorithm is complex. Contents of the invention [0003] In view of this, the pre...
