For depth frame rate measurement, depth matching was computed locally on the integrated Jetson Xavier NX module using HS-NX90X. Modes: Quality Near = SGM-128 / Quality Far = SGM-64 / Fast = BM-128


Precision values are result of calculation of the theoretical maximum based on the given stereo camera setup. Practical values may be affected by image noise, ambient illumination and surface texture.


The image resolution may be set to 2016x1520 pixels, which decreases the rolling shutter effect and is beneficial for the imager sensitivity (noise and brightness). This behavior is called “binning” and can be enabled via software. For information on how to use it, see application service.

HS-NX is available in two different embedded computing configurations using the following Developer Kits

  • N: NVIDIA® Jetson Nano™

  • X: NVIDIA® Jetson Xavier NX™

Physical Information


200 mm × 87 mm × 45 mm (W × L × H)

Mounting Options

1× 1/4-20 UNC standard tripod mount

2× M4×0.7-6H blind tapped holes


HS-NX is passively cooled. To ensure proper cooling an unobstructed airflow around the enclosure is necessary, especially around the cooling fins. Please use only the provided mounting options and leave at least 10 cm of clearance around the enclosure.

Power supply

HS-NX is driven by a DC power source. A suitable power supply for the respective model is part of the delivery. If a customer specific solution for the power supply unit is to be used, the specifications described in Table 6.3 must be met.


Using a power supply that does not fulfill the above specifications may result in irreversible damage of HS-NX!


Cables are not included in the scope of delivery. The responsibility for proper wiring is up to the user. The possible options for connecting the device are shown in Fig. 6.1.


Always make sure that the cables are properly strain-relieved. A load on the connections of HS-NX due to cable movement must be avoided. Also pay attention to the correct bending radii of the cables during installation.

Mounting options

HS-NX offers multiple mounting options on the back of the enclosure. Please see Fig. 6.3 for details. For setup or static applications the 1/4-20 UNC standard tripod mount can be used. For dynamic scenarios the mounting with two M4 screws (strength class 8.8) is required. The screws have to be tightened with a torque of 2.6 Nm and must be secured with medium strength threadlocker (e.g. Loctite 243) against unintentional loosening.

For a wide range of standard applications, an optional, adjustable universal mount is available. For more details please refer to Accessories.

Coordinate system

Two different coordinate systems are defined for HS-NX. A camera coordinate system and a mounting coordinate system. The origin of the camera coordinate system is positioned in the center of the left camera. The mounting coordinate system is positioned in the center of the tripod mounting hole. The approximate location and orientation of the coordinate systems for the two different optical configurations is shown in Fig. 6.4 and Fig. 6.5.
