Learning: In `src/device/DeviceBase.cpp`, `DeviceBase::startPipelineImpl` intentionally auto-enables the IR laser dot projector to 100% by default whenever the pipeline contains a `StereoDepth` node, with no dedicated opt-out (env var, BoardConfig, or pipeline option). This is a deliberate default-behavior change; users who want different projector intensity/behavior can override it via `DeviceBase::setIrLaserDotProjectorIntensity()` after pipeline start.

Move the SIGINT handler registration into stress_test().
signal.signal runs at import time. Any module that imports utilities/stress_test.py loses its own SIGINT handling. The handler also duplicates work: the default handler already raises KeyboardInterrupt, and the finally block at Line 394 already calls cv2.destroyAllWindows().

Guard against requestOutput returning None.
CAMERA_SIZE is fixed at 1280x800 for every sensor. Camera.requestOutput returns None when the sensor cannot satisfy the request. Line 188 then calls createOutputQueue() on None and the script crashes during pipeline construction. The code already prints feature.width/feature.height, so it can fall back.

Draw detections on a copy of the cached frame.
Line 346 stores the frame array, and add_detection_overlay mutates it in place. When a detections packet arrives without a new camera frame, the overlay is drawn again on the already annotated array. Boxes and text then stack up on the display.

DepthAI CameraControl setManualExposure valid exposure time and ISO ranges
💡 Result:
In DepthAI, the setManualExposure method within dai.CameraControl is used to manually configure exposure settings. While these values are passed as integers, there are typical operating ranges recognized by the DepthAI SDK, primarily based on the sensor capabilities and common example implementations [1][2][3]. The conventional ranges for manual exposure are: - Exposure Time: 1 to 33,000 microseconds (μs) [1][2][3] - Sensitivity (ISO): 100 to 1,600 [1][2][4][5] These ranges are consistently used in official Luxonis DepthAI examples and documentation [1][2][3]. Note that while the API accepts these types, the actual supported limits may vary slightly depending on the specific camera sensor module being used and the set frame rate (which dictates the maximum possible exposure time per frame). Always clamp your values within these ranges to ensure expected behavior [1][2][6].

🌐 Web query:
site:docs.luxonis.com setManualExposure exposureTime sensitivity valid range sensor frame rate
💡 Result:
The setManualExposure function is used to manually control camera sensor exposure settings, typically within the DepthAI/Luxonis ecosystem [1][2]. Its behavior and parameters are fundamentally constrained by the frame rate and specific sensor hardware [3][4]. Key concepts and ranges: Exposure Time (exposureTimeUs): This is measured in microseconds (μs) [1][2]. While the absolute numerical range can vary, a common practical range is 1 to 33,000 μs [5][6]. Crucially, the maximum exposure time is strictly limited by the frame duration, defined as 1 / CAM_FPS [3][4]. For example, at 30 FPS, the maximum exposure time is approximately 33 ms (33,000 μs) [3][7][4]. If you require longer exposure times, you must reduce the camera frame rate [7][8]. Sensitivity (sensitivityIso): This represents the sensor's ISO sensitivity [1][2]. The common valid range is 100 to 1600, though this may vary depending on the specific sensor model [1][5][6]. Relationship with Frame Rate: - The frame rate dictates the upper bound of the exposure time [3][4]. - Increasing the frame rate decreases the maximum available exposure time [7]. - If you attempt to set an exposure time exceeding the frame duration, the sensor will be physically unable to achieve it within the allotted time per frame [3][4]. - To achieve longer exposures (e.g., for low-light conditions), you must explicitly lower the camera frame rate (e.g., to 10 FPS or 5 FPS) [7][8]. Anti-Banding: Auto-exposure limits are also influenced by Anti-Banding (flicker reduction) modes [3][4]. When using auto-exposure, the algorithm will cap exposure times based on the mains frequency (e.g., 25 ms for 60Hz or 30 ms for 50Hz) to prevent flickering, which further restricts the available exposure range compared to manual mode [3][4].
