Structured Light

The Zivid camera functions on the principle of structured light. The camera contains a projector and a camera that is placed at a specific distance and angle to each other. Light patterns are projected by the projector onto the object and captured by the camera. The displacements in the light patterns are used to calculate the depth of the object at every point, giving you a 3D model of your object.

Signal level, noise and light intensity

One of Zivid’s most unique features is the HDR capability. ‘Difficult’ objects are made easy with this feature. The HDR mode works with multiple settings including (but not limited to) multiple apertures. The camera creates acquisitions with each specified f-number and then combines these acquisitions into one high quality frame. This is especially useful because different colors and different materials work better with different aperture settings. Lighter colors have better results with higher f-numbers, while darker colors need more light (low f-numbers) for a good 3D point cloud. With the HDR function you needn’t compromise on image quality when you have a combination of materials and colors and shiny metallic objects.
