We are excited to share our work “Event-Aided Sharp Radiance Field Reconstruction for Fast-Flying Drones” published in IEEE Transactions on Robotics IEEE Transactions on Robotics (T-RO), which tackles sharp radiance field reconstruction under agile drone motion, where RGB frames are heavily motion-blurred and pose priors become unreliable! 4 years in the making! Code & dataset released! PDF: Code & Dataset: Full Narrated Video: High-speed flight is essential for time- and battery-constrained missions (e.g., inspection, exploration, search & rescue). However, fast motion corrupts visual data with severe motion blur and introduces drift/noise in visual-inertial odometry, making NeRF-based 3D reconstruction particularly brittle. We propose a unified framework that leverages asynchronous #EventCamera streams together with motion-blurred frames to reconstruct high-fidelity radiance fields from agile drone flights. Our key idea is to embed event-image fusion directly into radiance field optimization while jointly refining a shared, continuous-time camera trajectory initialized from event-based VIO. This enables us to recover sharp radiance fields and accurate trajectories without ground-truth supervision during training. We validate our method on synthetic data and on real sequences captured by a drone flying up to 2 m/s. Despite severe blur and noisy pose priors, our method preserves fine scene details and achieves a performance gain of over 50% on real-world data compared to state-of-the-art methods.

🎋MOCOPI vs VIVE TRACKERS🎋 I got a crazy crazy upgrade on full body tracking thanks to the support of my bambuds, so I made a silly dance comparison to compare the tracking between my old FBT and my new one!! ✨ I danced Bibbidiba by Suisei! (ft. bae as my guide lol) I had to use a different model for the Vive comparison because my Toffee model doesn't work well with the trackers! PROS AND CONS 🔽 1. Mocopi is SO MUCH EASIER to set up! It's very very beginner friendly as well and a great asset to get if you're just starting on doing 3D stuff or want to try it out! Vive trackers are lowkey a pain to set up each time! 2. Vive trackers are EXPENSIIIVEEEE!!!!! The tracking is so so so good but only invest in it if you plan to do lots of 3D content! Mocopi is a much affordable option! 3. Related to point 2, but you get what you pay for when it comes to tracking. Vive may be more expensive, but the tracking quality and accuracy makes it worth it. 4. This is only for people that don't have the Valve Headset, but I use a Quest 3 and I have to do EXTRA SETUP to calibrate the trackers with an external program to use in VRChat! (Mocopi also needs an external program (SlimeVR) but it's much easier to set up imo). 5. Since calibration is paired to your headset with the vive trackers, if your headset goes to sleep or something the calibration will be LOST and you will have to recalibrate again which may take 1 to 2 minutes. Mocopi doesn't have this issue and recalibrating is only one button. 6. Mocopi is an IMU so no base stations required but because of this the trackers need to be recalibrated A LOT of times. This may be annoying if you're streaming and you constantly have to press the button to recalibrate. Vive trackers may take longer but you VERY RARELY have to recalibrate if your headset doesn't go to sleep. 7. Vive trackers take a lot of space on your setup. Each tracker needs to be connected to the PC so if you have a lot you may need to buy an USD hub! 8. You need to have a good room space to use vive trackers properly because the base stations need to have a clear view of your trackers or else they can lose tracking! Mocopi is an IMU, so no amount of obstruction will make the trackers lose tracking. 9. The amount of poses and movement that you can do with vive trackers is NIGHT AND DAY compared to the mocopi. A lot of poses or rapid movements will make the mocopis mess up their tracking and you will have to recalibrate. Vive trackers will not need any recalibration. Basically if you're a vtuber that only wants to dabble into 3D content as a fun little thing I think mocopis are very much a good choice! But if you'd like to do 3D stuff that require more intensive tracking like dancing, vive trackers are excellent and very much worth the price!

Everyone is sleeping on Meta's SAM 3 release. But it's actually a big deal. Here's why: Companies spend millions paying humans to label images and videos frame by frame. A single autonomous driving dataset? Months of work, hundreds of annotators, millions in cost. Without labeled data, you can't train custom models. Without custom models, you're stuck with generic solutions. This is why most companies never move past pilots. SAM 3 breaks this cycle. First let's look at the evolution: SAM 1 segmented objects when you clicked on them. Revolutionary, but one object at a time. SAM 2 added video tracking with memory. Game-changing, but you still manually prompted every object. SAM 3 changes everything with text prompts. Type "yellow school bus" and it finds ALL of them in your image or video. Not just one. Every instance across thousands of frames. Now here's where people get confused: "Can't I just use GPT-5 or Gemini for this?" No, and here's why that's a terrible approach. Large multimodal LLMs are great for reasoning, but they're slow and expensive for production visual tasks. You're paying API costs per image, waiting seconds for responses, getting inconsistent results. SAM 3 runs in 30 milliseconds on a single GPU for 100+ objects. That's 100x faster, and you own the infrastructure. More importantly, SAM 3 gives you precise pixel-level masks, not descriptions. Try asking an LLM to segment every defective part on a manufacturing line in real-time. It won't work. SAM 3 does this effortlessly. The real breakthrough is their data engine. Meta built an AI-human hybrid system that's 5x faster for complex annotations. They trained SAM 3 on 4 million unique visual concepts - 50x more than existing benchmarks like LVIS. SAM 3 is trained on 4 million unique visual concepts, it handles everything: - Text-based concept search - Interactive refinement with clicks - Video tracking across frames - Zero-shot detection of new concepts The model is open source. Weights, code, and benchmarks are on GitHub. If you're building computer vision applications, this is the foundation model to evaluate. The annotation time savings alone will pay for integration costs within weeks. Find the relevant links in the next tweet!

Tiny drone hits invisible mode by twisting faster than eye can detect | Omar Kardoudi, New Atlas Engineers at Northwestern University have built a drone that vanishes without camouflage or transparent panels. Its trick is spinning so fast that your eyes simply give up trying to focus, a stealth edge that could turn surveillance into something almost invisible. The aircraft, nicknamed Phantom Twist, rotates up to 25 times per second, a rate that outpaces how quickly our visual system can process sharp detail. Instead of true invisibility, the drone dissolves into a faint, ghostly blur that blends into whatever is behind it. The work, led by associate professor Michael Rubenstein, was presented on July 16 at the Robotics: Science and Systems 2026 conference in Sydney, Australia, under the title Computational Design of a Low-Visibility UAV Using Human-Aligned Perceptual Metric. "Most efforts to hide drones focus on making them look like their surroundings," says Rubenstein. "Instead, we asked whether we could design the drone itself around the way humans perceive motion. This idea of low visibility through persistent motion is something few people have explored." That distinction matters because drones are increasingly used to watch wildlife, check aging infrastructure, or survey wetlands, but their mere presence changes the behavior of whatever they're observing. Birds scatter, animals flee, people act differently. A drone that's hard to spot could do the same job without that side effect. Prior attempts at motion-based concealment offer useful context here. The Northwestern paper points to an earlier project nicknamed the Boomerang Drone, covered in a 2006 New York Times Magazine piece, which tried a similar high-speed rotation trick but couldn't spin fast enough to fully exploit the blur effect, leaving it largely visible. The paper authors also trace the broader idea of active concealment back to the "Yehudi light," a counter-illumination project developed by the National Defense Research Committee in 1944 to hide Allied sea-search aircraft from enemy view. The Phantom Twist itself takes a very different shape from those earlier attempts. Rather than a typical quadcopter with four separate rotors, it runs on a single motor and a single propeller, with the propeller spinning one way while the rest of the drone's body spins the opposite way. "For a typical quadrotor drone, the propellers are spinning, but the robot is stationary," Rubenstein explains. "So, you still see its body. For our drone, the whole thing is rotating, so there are no stationary parts." To reach that layout, the team's computer model generated roughly 20,000 possible drone configurations capable of stable flight, then used artificial intelligence and optimization algorithms to repeatedly rearrange the motor, propeller, circuit board, counterweight, and batteries. Each design was simulated spinning mid-flight and overlaid on 100 real-world backgrounds, then scored by a perceptual model built to mimic human vision, where a lower score meant better camouflage. The 500 best-scoring designs were run through the optimizer again to squeeze out further gains before a final version was built. Emma Alexander, an assistant professor of computer science and one of the study's co-authors, explains the underlying physics. "The human eye takes time to accumulate signals, roughly analogous to the exposure time of a camera," she says. "When an object spins quickly, we perceive it as blurring out and losing distinct features. Because this new drone is almost entirely transparent, its few opaque components are visually averaged with the background for an overall appearance of a slight haze." According to the paper's visibility metric, the finished drone is about 10 times harder to spot than a standard quadcopter. But the spinning trick has real limits that make this drone far from being completely unnoticeable. The propeller still makes an audible whir that gives the drone away even when the eye can't, and its support wires and rods remain partly visible. The paper's authors suggest future versions could lean on more transparent materials and quieter propulsion, edging the drone ever closer to true – and somewhat scary – invisibility. After all, the same trick making a drone less impactful on wildlife could just as easily help it sneak around for reasons that aren't so friendly.
