LiDAR View vs SimpleSSTV

LiDAR View provides real-time visualization of both LiDAR depth data and camera imagery. You can choose to display the camera view, the LiDAR view, or a combined view that merges both sources for enhanced environmental awareness and depth perception. * LiDAR modes (Options 3 and 4) are especially effective in low-light or dark environments, helping reveal surrounding structures and spatial depth. The visible range can be adjusted using the slider at the bottom of the screen. * Combined modes (Options 2 and 4) blend camera and LiDAR data to enhance object contours and depth details. * In Combined modes, tap the subview to enlarge it for a more detailed inspection. Tap the enlarged view again to return to the combined layout. * The center-point depth is displayed in real time in centimeters. You can capture screenshots at any time by tapping the camera icon, and browse saved images through the photo icon. The built-in flashlight can be enabled using the torch icon. Swipe left on the number icon to access two additional viewing modes: * 3D Point Cloud View — Freely explore the surrounding environment in an interactive 3D perspective by panning the screen. * Stereo View — Experience immersive real-time stereo visualization using Google Cardboard or a compatible VR headset. If you want to view front depth image through TrueDepth camera and front camera, please check our app "FrontDepth View".

SimpleSSTV is a native iOS app for encoding, decoding, and live-transmitting slow-scan television (SSTV) signals — the method ham radio operators use to share images over audio frequencies. Slow-scan television converts images to audio tones. Each pixel's brightness becomes a specific frequency between 1500-2300 Hz. Sync pulses at 1200 Hz mark line boundaries. The result is an audio signal you can transmit over any voice-capable radio, or record for later playback. SSTV has been used by amateur radio operators since the 1950s. It's still actively used today on HF bands, VHF repeaters, and for receiving images from the International Space Station.
