Image Windows

When starting image acquisition using the blaze Viewer, four windows are opened in the image window area. They show 3D and 2D views of the scene that the camera is capturing.

Each point in the cloud holds three values representing the XYZ coordinates of the point from which the light has been reflected.

By default, the point cloud is displayed utilizing the information from the intensity image, a gray value image representing the brightness of the reflected light pulses (near-infrared). Using the Window menu, you can open additional point cloud windows in color where the point cloud data is used for coloring near points red and far away points blue.

The range map is calculated from the point cloud data. By default, the range map is displayed in color. Using the Windows menu, you can open additional range map windows in color or using gray values.

The intensity image shows the brightness of the reflected light pulses (near-infrared and ambient light). The closer an object is, the brighter it appears in the intensity image.

The confidence map represents a measure of how reliable the depth image data is. The higher the value, i.e., the brighter the pixel, the more reliable the measurement.

All of these image components can be saved as separate files using the Save Depth and Image Data option. For more information, click here.

 

The image windows displayed in the blaze Viewer are only visual representations of the data that the camera transmits. This means that if you close a window, this will not stop the camera transmitting the data to your computer.

Using the Pixel Information Pane

You can pick any point in any of the image windows to get more details about it in the Pixel Information pane. The following information is available:

The location of the pixel on the sensor.

The position of the pixel in a three-dimensional coordinate system.

The intensity value of the pixel.

The distance of the point in mm.

The mean distance of the point in mm. The mean distance is calculated by averaging the distance values of neighboring pixels.

 

When picking a point, be aware of the following:
