Here&#8217;s the core process: <\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Light Emission:<\/strong> The LiDAR sensor emits rapid pulses of infrared light. &nbsp;<\/li>\n\n\n\n<li><strong>Reflection:<\/strong> These light pulses travel outward and bounce off objects in the environment. &nbsp;<\/li>\n\n\n\n<li><strong>Time Measurement:<\/strong> The sensor measures the time it takes for the reflected light to return. &nbsp;<\/li>\n\n\n\n<li><strong>Distance Calculation:<\/strong> By knowing the speed of light, the device calculates the distance to the object with high precision. &nbsp;<\/li>\n<\/ol>\n\n\n\n<p><strong>LiDAR on Mobile Phones<\/strong><\/p>\n\n\n\n<p>Mobile phone LiDAR systems are miniaturized versions of the technology used in other applications like autonomous vehicles or surveying.<sup><\/sup> Here&#8217;s how it works on your phone: &nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Integrated Sensor:<\/strong> A small LiDAR sensor is built into the phone, typically near the camera system. &nbsp;<\/li>\n\n\n\n<li><strong>Point Cloud Creation:<\/strong> The LiDAR sensor rapidly scans the environment, capturing thousands of distance measurements. These measurements are used to create a &#8220;point cloud,&#8221; which is a 3D map of the surroundings composed of individual points in space. &nbsp;<\/li>\n\n\n\n<li><strong>Data Processing:<\/strong> The phone&#8217;s processor analyzes the point cloud data to understand the shape, size, and distance of objects in the scene. &nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>Key Differences from Traditional LiDAR<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Smaller Size and Range:<\/strong> Mobile phone LiDAR systems have a shorter range and lower power compared to larger LiDAR systems used in other applications. They are designed for indoor and close-range outdoor use. &nbsp;<\/li>\n\n\n\n<li><strong>Integration with Other Sensors:<\/strong> Mobile phone LiDAR works in conjunction with other sensors like cameras, accelerometers, and gyroscopes to provide a more complete understanding of the environment. &nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>Applications on Mobile Phones<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Augmented Reality (AR):<\/strong> LiDAR significantly enhances AR experiences by providing accurate depth sensing and object placement. This allows virtual objects to be realistically placed in the real world, interacting with the environment in a believable way. &nbsp;<\/li>\n\n\n\n<li><strong>Improved Photography:<\/strong> LiDAR assists with autofocus, especially in low-light conditions, and improves portrait mode by accurately separating the subject from the background. &nbsp;<\/li>\n\n\n\n<li><strong>3D Scanning:<\/strong> Some apps use LiDAR to create 3D models of objects or spaces. &nbsp;<\/li>\n\n\n\n<li><strong>Measurement Apps:<\/strong> LiDAR enables more accurate measurements in apps that use the camera to measure distances or dimensions. &nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>Advantages of LiDAR on Mobile Phones<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Increased Accuracy:<\/strong> LiDAR provides much more accurate depth information compared to relying solely on cameras and software-based depth estimation. &nbsp;<\/li>\n\n\n\n<li><strong>Improved Low-Light Performance:<\/strong> LiDAR works independently of ambient light, making it effective in low-light or even complete darkness. &nbsp;<\/li>\n\n\n\n<li><strong>Faster and More Reliable AR:<\/strong> LiDAR enables faster and more stable AR experiences with more realistic object placement and interactions.<\/li>\n<\/ul>\n\n\n\n<p><strong>NERF<\/strong><\/p>\n\n\n\n<p><strong>Neural Radiance Fields (NeRF)<\/strong> is a deep learning technique that uses neural networks to reconstruct a 3D scene from a set of 2D images, allowing the generation of photorealistic images from novel viewpoints, essentially creating a complete 3D representation of a scene based on multiple 2D perspectives; it&#8217;s particularly useful for applications like virtual reality, computer graphics, and 3D modeling where realistic rendering from any angle is desired.<br><br>Function: NeRF learns the geometry and appearance of a scene by analyzing multiple images taken from different angles, enabling it to predict the color and density of light at any point in 3D space.<br>How it works: A neural network is trained on the input images, where each pixel is associated with a 3D point in space and its corresponding color.<br>Applications: Novel view synthesis: Generating realistic images from viewpoints not captured in the original set of images<br>3D reconstruction: Creating a complete 3D model of a scene from 2D images<br>Augmented reality: Integrating virtual objects seamlessly into real-world scenes<br><br>NERF EXAMPLES:<br><a href=\"https:\/\/www.matthewtancik.com\/nerf\" target=\"_blank\"

videos.<sup><\/sup> It&#8217;s gaining popularity due to its ability to render complex scenes in real-time with impressive quality.<sup><\/sup> &nbsp;<\/p>\n\n\n\n<p><strong>1. Representing Scenes with 3D Gaussians:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Instead of using traditional 3D models made of polygons or meshes, Gaussian Splatting represents a scene as a collection of millions of tiny 3D Gaussians. &nbsp;<\/li>\n\n\n\n<li>A Gaussian is a type of mathematical function that creates a bell-shaped curve. In 3D, it forms an ellipsoid (a 3D ellipse). &nbsp;<\/li>\n\n\n\n<li>Each Gaussian has properties like:\n<ul class=\"wp-block-list\">\n<li><strong>3D position:<\/strong> Where it&#8217;s located in space. &nbsp;<\/li>\n\n\n\n<li><strong>Orientation:<\/strong> Its rotation in 3D space. &nbsp;<\/li>\n\n\n\n<li><strong>3D scale:<\/strong> Its size and shape (how stretched or compressed the ellipsoid is). &nbsp;<\/li>\n\n\n\n<li><strong>Opacity:<\/strong> How transparent or opaque it is.<\/li>\n\n\n\n<li><strong>View-dependent color:<\/strong> The color it appears to have from different viewing angles. &nbsp;<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p><strong>2. &#8220;Splatting&#8221; onto the 2D Image:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To render an image of the scene from a particular viewpoint, these 3D Gaussians are &#8220;splatted&#8221; onto the 2D image plane. &nbsp;<\/li>\n\n\n\n<li>This means that each Gaussian is projected onto the 2D image as a 2D ellipse, with its size, shape, and color determined by its properties and the viewing angle. &nbsp;<\/li>\n\n\n\n<li>The contribution of each Gaussian to the final pixel color is weighted based on its opacity and how much it overlaps with that pixel. &nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Efficient Rendering:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A key advantage of Gaussian Splatting is its efficient rendering process. Because the scene is represented by simple geometric shapes (ellipses), it can be rendered very quickly using standard graphics hardware. &nbsp;<\/li>\n\n\n\n<li>This allows for real-time rendering of complex scenes, which is crucial for applications like virtual reality, augmented reality, and interactive 3D environments. &nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>Key Advantages over other methods:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High Quality:<\/strong> Gaussian Splatting can produce very high-quality renderings with detailed textures and complex view-dependent effects. &nbsp;<\/li>\n\n\n\n<li><strong>Real-time Performance:<\/strong> It enables real-time rendering, which is a significant advantage over other techniques like Neural Radiance Fields (NeRFs) that can be computationally intensive. &nbsp;<\/li>\n\n\n\n<li><strong>Relatively Simple:<\/strong> Compared to some other advanced rendering techniques, Gaussian Splatting is conceptually simpler to understand and implement.<\/li>\n<\/ul>\n\n\n\n<p><strong>Applications:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Virtual and Augmented Reality:<\/strong> Creating realistic virtual environments and AR experiences. &nbsp;<\/li>\n\n\n\n<li><strong>3D Reconstruction:<\/strong> Generating 3D models from photos or videos. &nbsp;<\/li>\n\n\n\n<li><strong>Film and Visual Effects:<\/strong> Creating stunning visual effects for movies and TV shows.<\/li>\n\n\n\n<li><strong>Gaming:<\/strong> Rendering realistic game environments.<\/li>\n<\/ul>\n\n\n\n<p>This is probably one of the most beautiful examples of LIDAR scanning in super large scale with a clever usage of Gaussian Splatter<\/p>\n\n\n\n<p><strong>REAL
