Environment sensing system and mobile platform using the same

Abstract

The invention discloses an environment sensing system and a mobile platform using the same. The environment sensing system comprises a laser detection module; the laser detection module comprises a first laser module (21), a second laser module (22), a third laser module (23) and a fourth laser module (24); the field angle of each laser module is smaller than or equal to 120 degrees, the first laser module and the second laser module are both arranged on the front side of the mobile platform, and the fields of view of the first laser module and the second laser module are partially overlappedto detect areas in front of the left and the right of the mobile platform. According to the system, detection of a larger area around the mobile platform can be realized by using a small number of laser modules, so that redundancy and reliability of the system can be enhanced, real-time effective perception of the environment can be realized and the cost can be reduced.

Description

technical field [0001] The present invention generally relates to the field of automatic driving, and more specifically relates to an environment perception system and a mobile platform. Background technique [0002] Self-driving cars can realize 360-degree perception of the surrounding environment through multiple sensors, and conduct autonomous navigation to lead passengers to their destinations. Now, many companies such as Google, Tesla, etc. are designing their own automatic driving systems, in which the selection and location of different types of sensors are designed, and the calibration of multi-sensors, environmental perception, control decision-making and other modules in the automatic driving system will have an important impact. A better autonomous driving sensor system should meet the following conditions: 1) Realize 360-degree perception of the surrounding environment without dead angle; 2) Provide reliable and stable environmental perception data with less red...

Problems solved by technology

[0003] Different sensors have their own advantages and disadvantages. For example, visible light cameras can detect various vehicles and pedestrians, but there may be a greater probability of false detection when the light is too strong or too dark. Although lidar cannot provide color information, However, it can provide stable distance detection information, which is of great significance to automatic obstacle avoidance. However, most of the laser radars currently used have high prices and are difficult to be embedded in the body, which is a major obstacle to the popularization of automatic driving technology; In addition, sensors such as wheel odometer, ultrasonic wave, and millimeter-wave radar have important practical value for car navigation and positioning and environmental perception.
