Embodiment Construction

[0106] Human beings are entering the information age, and computers will be more and more widely used in almost all fields. On the one hand, more people without computer professional training also need to use computers, and on the other hand, computers are becoming more and more powerful and using methods are becoming more and more complicated. This creates a sharp contradiction between the flexibility that people have when they talk and communicate, and the rigor and rigidity that is required when using computers. People can exchange information with the outside world through vision, hearing, and language, and can express the same meaning in different ways, but computers require programs to be written in strict accordance with various programming languages, only in this way can the computer run. In order to enable more people to use complex computers, it is necessary to change the past situation in which people adapt to computers and memorize the rules of use of computers by ...

Abstract

The invention discloses a method and device for joint calibration of sensors, which are used to solve the problem of poor joint calibration accuracy of heterogeneous sensors in the prior art. In the specific implementation, after the coordinate transformation matrix between every two sensors is determined according to the pose information collected by multiple different types of sensors, the pose between the coordinate transformation matrices between the determined multiple sensors will also be Consistency is verified, and only the coordinate transformation matrix that is verified is determined as the final coordinate transformation matrix. Joint verification is carried out to improve the joint calibration accuracy of sensors.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and device for joint calibration of sensors. Background technique [0002] Computer vision is a science that studies how to make machines "see". To put it further, it refers to using cameras and computers instead of human eyes to identify, track and measure targets, and further graphics processing, so that computer processing It becomes an image that is more suitable for human eyes to observe or sent to the instrument for detection. [0003] At present, sensor calibration is a common object calibration technology applied in the field of computer vision. Usually, the sensor is used to obtain the pose information including the target object, and then the target object is calibrated according to the collected pose information. It is generally divided into two types: single-sensor self-calibration and multi-sensor joint calibration. Multi-sensor joint calibration is...
