Calibration, explained in terms of a single camera since each camera is calibrated separately, determines the parameters of the camera model, which involves the four coordinate systems (CSs) depicted in Figure 1: (i) the three-dimensional (3D) world CS having arbitrary orientation and position; ...

Note that the stereo camera calibration is useful only when the images are captured by a pair of cameras rigidly fixed with respect to each other. If a single camera captures the images from two different angles, then we can find depth only to a scale. The absolute depth is unknown unless...
Integrate multi-sensor data from a single camera such as IMU and stereo images. Fuse data with external sensor sources such as GPS or LiDAR. Getting Time Synced Sensors Data # Sensors data is accessible by using the function getSensorsData(sensors_data, TIME_REFERENCE) as explained in the Usi...
The folder settings contains the camera settings files which can be used for testing the code. These are the same used in the framework ORB-SLAM2. You can easily modify one of those files for creating your own new calibration file (for your new datasets). In order to calibrate your camera...

Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The inventio...
on-board Image Signal Processor. The color images are stored in individual PNG files with no compression. Nonetheless, calibration parameters are included in the dataset to allow ad-hoc rectification and undistortion procedures. The method we used to model the distortion is thoroughly explained in20...
In parallel we plan to improve the hardware and the image capturing process. We will make a light enclosure and a more rigid frame to eliminate the need for additional field calibration, caused by minor variations (mostly thermal) of the camera sensors attitudes. We will try to use fusion of...
The main function is very standard and is explained in detail in the “Talker/Listener” ROS tutorial. The most important lesson of the above code is how the subscribers are defined: // Subscribers ros::Subscriber subRightRectified = n.subscribe("/zed/right/image_rect_color", 10, imageRight...
