Worse, there are times after running what appears to be a successful calibration that the tools cannot ‘find’ the configuration files. So calibrating at night was the only option. In my house, the only time it’s dark is at night. So much so that about the only time a good calibration could be made is when the room was dark. Unfortunately the calibration is effected by the lighting conditions when the test is being run. The second installation issue is the ZED Camera calibration. Unfortunately it wasn’t around when I first encountered the issue. Note: In the reorganization of the website, Stereolabs now has a page for troubleshooting this very issue. Having had to support this very issue over the last decade or so, I knew how to fix it. This is odd, as the installer made it a point to ask for confirmation when installing the related Microsoft Visual C++ Redistributable Package. The ZED was connected to the PC, and then the dreaded ‘ MSVCP120.dll is missing‘ message popped up. The Stereolabs package was downloaded from their website and installed on the PC. The PC here is an older, slower machine and doesn’t appear to care much for all that is new and shiny. Before most of the tools could work, a firmware upgrade was needed for the camera. While downloading and installing the SDK was simple, actually getting the ZED to work was quite challenging in the development environment here.įirst, we started using the ZED camera here over a year ago. The installer gives the option of also installing sample code, useful for development purposes. Download it from the website, set the permissions, and then run the installer from a terminal. Stereolabs recently updated their website to facilitate better interaction. The Jetson acts as the host computer for the ZED in this article. Stereolabs has a Github repository with a lot of code for project support, which is worth checking out. These functions include such interesting tasks as 6-axis Positional Tracking (visual odometery, no markers needed) and large-scale 3D environment mapping. There are a variety of other APIs in the ZED SDK which do further processing. The small package and relatively light weight make the ZED an interesting choice for robotics and other mobile applications. The host computer then constructs a depth image using a GPU. For each frame, a composite of the left and right images (side by side) are sent over USB 3.0 to a host computer. The ZED Camera is a stereo depth sensor which contains two 4 megapixel imagers. The Stereolabs ZED Camera is introducing SDK 2.0 which includes support for the Jetson TX1 and Jetson TX2.
