DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT METHOD, AND DISTANCE MEASUREMENT PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18585670 titled 'DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT METHOD, AND DISTANCE MEASUREMENT PROGRAM
The patent application describes a distance measurement device that utilizes directional light to determine the distance to a subject.
- The device includes an imaging unit, emission unit, light receiving unit, derivation unit, display unit, and control unit.
- The imaging unit captures a subject image formed by an imaging optical system.
- The emission unit emits directional light along the optical axis direction of the imaging optical system.
- The light receiving unit receives reflected light of the directional light from the subject.
- The derivation unit calculates the distance to the subject based on the timing of emitting directional light and receiving reflected light.
- The display unit shows the subject image as a motion image during distance measurement.
- The control unit transitions to a state where actual exposure by the imaging unit is possible at the end of the distance measurement.
Potential Applications: - Photography and videography for accurate distance measurements. - Autonomous vehicles for obstacle detection and navigation. - Robotics for object recognition and manipulation.
Problems Solved: - Accurate distance measurement using directional light. - Real-time display of subject image during distance measurement. - Seamless transition to actual exposure after distance measurement.
Benefits: - Improved accuracy in distance measurement. - Enhanced user experience with real-time display. - Efficient workflow with automated exposure transition.
Commercial Applications: Title: "Innovative Distance Measurement Device for Enhanced Imaging" This technology can be utilized in industries such as photography, videography, autonomous vehicles, and robotics for improved performance and efficiency.
Questions about the technology: 1. How does the device ensure accurate distance measurement using directional light? 2. What are the advantages of displaying the subject image as a motion image during distance measurement?
Original Abstract Submitted
A distance measurement device includes an imaging unit which captures a subject image formed by an imaging optical system, an emission unit which emits directional light as light having directivity along an optical axis direction of the imaging optical system, a light receiving unit which receives reflected light of the directional light from the subject, a derivation unit which derives a distance to the subject based on the timing at which the directional light is emitted and the timing at which the reflected light is received, a display unit which displays the subject image, and a control unit which performs control such that, in a case of performing a distance measurement, the display unit displays the subject image as a motion image and transition is made to a state where actual exposure by the imaging unit is possible at the timing of the end of the distance measurement.
