4.4 Achievable Frame Rates and Image Resolutions
The maximum frame rate that can be achieved depends on the image size and
the congured disparity range. Table 2 provides a list of recommended cong-
urations. This is only a subset of the available conguration space. Diering
image resolutions and disparity ranges can be used to meet specic application
requirements.
5 Mechanical Specications
5.1 Dimensions
Figures 1a and 1b show SceneScan as seen from the front and from the side.
The provided dimensions are measured in millimeters.
5.2 Mounting
The casing of SceneScan features two mounting brackets to the sides of the de-
vice. Each mounting bracket has two slotted holes, which allows SceneScan to
be mounted onto a at surface. The dimensions and placement of the mount-
ing brackets are depicted in Figure 2. In order to support heat dissipation, it
is recommended to mount the device onto a surface made of metal
or another material with a high heat conductivity.
