SpletThe format of xyz_image must be K4A_IMAGE_FORMAT_CUSTOM. The width and height of xyz_image must match the width and height of depth_image. xyz_image must have a stride in bytes of at least 6 times its width in pixels. Each pixel of the xyz_image consists of three int16_t values, totaling 6 bytes. The three int16_t values are the X, Y, and Z ... Splet20. feb. 2024 · Usually you would have to project the point cloud onto an image plane using the focal lengths and center position.

SpletmaxAngleWidth=360 and maxAngleHeight=180 mean that the range sensor we are simulating has a complete 360 degree view of the surrounding. You can always use this … SpletHow you process that is up to you, but the most simple way would be to cast image_p.x and image_p.y as integers, make sure they are withing image boundaries and set depth_image.at(image_p.y, image_p.x) = p.Z;` mercury glass waste basket
