Abstract

The invention belongs to the technical field of intelligent automobiles, and provides a reflective strip and an intelligent automobile laser radar detection system. The intelligent automobile laser radar detection system comprises a reflective strip and two first static laser radars which are arranged at the front end of the body of an intelligent automobile and used for recognizing the reflectivestrip, wherein the two first static laser radars are respectively arranged at two sides of the front end of the body and set in a mode of facing towards the outer side of the front end of the body, the included angles between the two first static laser radars and the corresponding side surface of the body of the intelligent automobile are a first included angle, and the range of the first included angle is 1-18 degrees. Both sides of the front end of the body are provided with the first static laser radar at an appropriate angle, the road is provided with the reflective strip, and the reflective strip has a good diffuse reflecting ability for laser light emitted by the first static laser radars, so that the intelligent automobile can scan the reflective strip clearly and integrally at anyposition of the road, thereby effectively avoiding a problem of low road detection and recognition rate existing in dynamic laser radar.

Description

technical field [0001] The invention belongs to the technical field of smart cars, and more specifically relates to a reflective strip and a laser radar detection system for smart cars. Background technique [0002] Smart cars can use on-board sensors to perceive the environment around the vehicle, and control the steering and speed of the vehicle based on the information obtained from the perception of the road, vehicle position, and obstacles, so that the vehicle can run safely and reliably on the road . [0003] The current laser radar usually used in smart cars is a real-time three-dimensional rotating laser radar. This kind of laser radar uses a dynamic scanning method to sense the surroundings. Multiple laser transmitters and receivers rotate at a high speed in a horizontal dimension with a fixed height. Although The update frequency can reach 10Hz, and the number of points emitted is 2000 laser points. However, during the scanning process, there will still be situati...
