1. Product Brief
Integrating Orbbec’s latest custom ASIC, the Gemini 330 series of Depth + RGB cameras combine active and passive stereo vision technologies for seamless operation in both indoor and outdoor conditions. The depth image computation and the depth to color spatial alignment functions are processed inside the camera providing for minimal latency and reduced dependency on expensive and power-hungry external compute. The cameras are programmable for a variety of depth operating modes to adapt to different application scenarios. A flexible and rich frame synchronization mechanism makes multi-camera operations simple and scalable. The Gemini 330 series is easy to set up and operate with the Orbbec SDK, and the camera delivers extremely accurate and reliable data in various lighting conditions, ranging from pitch black to full sunshine.
Wide field of view at 90° horizontal and 65° vertical High quality depth data output in both indoor and outdoor environments Up to 30 fps at 1280 x 800 depth resolution USB Type-C for power and data connectivity Multi-camera synchronization and IMU supported

Depth Accuracy: ±2% (1280 x 800 @ 2m & 81% ROI): In these defined areas on the depth map, the median depth value of all points (excluding zero depth points and outliers) is calculated, and the average of N median depth values is taken. Z-Accuracy, expressed as a percentage, is calculated as the average median value divided by the true value, multiplied by 100, representing the absolute accuracy of the region. Spatial Precision: 1.5% (1280 x 800 @ 2m & 81% ROI): Fit a plane to all valid points within the computed area (excluding zero, invalid, and the smallest 0.5% of depths), and calculate the root mean square of the difference between the original depth values of the valid points (measured_z, i.e., the tested depth) and the fitted depth values (fitted_z). Fill Rate: >99% (1280 x 800 @ 2m & 81% ROI). Temporal Precision: 0.9% (1280 x 800 @ 2m & 81% ROI): Per-pixel temporal noise is defined by measuring the STD of depth values for each pixel across N consecutive frames, resulting in a STD matrix. Temporal Noise is defined as the median of the STD matrix as a percentage of the target distance Z. This metric excludes NaN and zero depth data. *Theoretical maximum depth range up to 65 meters.

The actual working range and accuracy may vary with the ambient illumination and the objects being measured. The test object is a reflectivity > 80% plane, and the reference range is 81% FOV (81% FOV is the remaining center 81% of the depth map area after cropping 5% of the top and bottom of the depth map) or 64% FOV (64% = 80% x 80% and of a similar definition). The depth performance of each 3D camera is validated at the production line before shipping to customers. The metrics reflect the depth performance under typical conditions. External impact factors over 3D cameras’ whole lifespan may have significant impacts on their depth performance.

Laser Ranging Module

The Gemini 335/336 and 335L/336L 3D cameras come equipped with a LRM (Laser Ranging Module) single-point laser ranging module. Essentially, it is a single-point dToF (direct time-of-flight) sensor that calculates relative distance by measuring the time it takes for light to travel from emission to reception. It is used for close-range ranging, helping the 3D camera to fill in blind spots at short distances and enhances the overall ranging performance of the depth camera.

5.5. Multi-Camera Synchronization
For a multi-camera use case, one camera can be initialized as primary, and the rest configured as secondary. Alternatively, an external signal generator can also be used as the primary trigger with all cameras set to secondary mode. When applying an external sync pulse, the HW SYNC input requires a 100-microsecond positive pulse at the nominal camera frame rate, e.g. 33.33 ms for a 30 Hz frame rate. Inputs are high impedance, 1.8V CMOS voltage levels. However, it is important to make sure to use a high-resolution signal generator. The frequency of the signal generator needs to exactly match the sensor frame rate. For example, if the sensor is set up as 30 FPS, the real frame rate may be 30.015 FPS. You may need to use an oscilloscope to measure the real frame rate and configure the signal generator to the same frequency. For this reason, it may be better to just use one additional camera as the primary sync signal generator. Advantages of multi-camera setup
o Increase camera coverage in a given space and fill in the occlusions where a single camera may have blind spots
o Capture multiple images of the same scene and scan objects from different angles
o Increase the effective frame rate to greater than 30 FPS Using an 8-pin connector and matching cable, a multi-camera and multi-sensor network can be designed. (Please follow the instructions in the SDK). Multi-camera frame synchronization in two topologies is supported, including depth image synchronization and RGB image synchronization (time difference 3ms, when auto exposure off), using the multi-camera synchronization function.

6.3 Depth Quality Assessment
Calculation of Depth Accuracy (Z-accuracy): Depth accuracy (Z-accuracy) refers to the difference between the depth of effective pixels on a fitted plane and the true value plane, which can be either positive or negative.
Calculation method: Use a flat plate parallel to the x-axis of the module, and measure the distance with a laser rangefinder or tape measure as the Ground Truth (GT) surface. Collect the depth map at the current distance, and obtain the difference between the effective pixels in the ROI area and the true values to create an error map. Use the median of the error map as the Z-accuracy of the current depth map. To avoid errors from single measurements, take N depth maps and calculate the average or the ratio of the average to the true values as the final Zaccuracy.
Calculation of Spatial Precision: The spatial precision is calculated as the percentage of the root mean square error (RMS Error) between each valid pixel and the optimal fitting plane compared to the true value (GT).
Depth Fill Rate Calculation: The fill rate is used to calculate the proportion of valid pixels to total pixels within the target area (ROI region), primarily used to measure the completeness of depth.
