OPT8241-CDK-EVM: Images in Voxel Viewports: how are they defined?

Part Number: OPT8241-CDK-EVM

In the Voxel Viewer, there are three images: the point cloud image in the Main Viewport, the Phase and the Amplitude in the Side Viewpoorts. The point cloud is similar to but a little different from the Amplitude image. Could you explain what exactly these two images are and their relationship please? Also, how is the Phase image generated and how the colors are defined? Thank you.

  • Hi SL,

    The three images in Voxel Viewer are:

    1) Amplitude Image: This is a grayscale image of the scene (values range between 0 and 4096 codes). We call this the "amplitude", gives the actual image of the scene. The black and white color scales when you reset the view (right-click + reset view)

    2) Phase image: This image gives the phase (angle) of every pixel in the scene. Red is for the nearest distance and blue is the farthest. All the other colors are in-between. Again, this can be scaled to see variations between the closest and the farthest points. The full scale is 4096 codes.

    3) Point Cloud image: This image is generated using the x, y, z and i values given out by the camera. The intensity is related to the amplitude, while (x, y and z) are given out by the phase and the pixel position. This image is created using OpenGL and you can see the 3-D view (you can click on the point-cloud image and press x or y to get the x and y direction views). The default is the z-direction view.
