Depth data measuring device and application method thereof
The invention discloses a depth data measuring device and an application method thereof. The measuring device comprises a projection assembly which is used for projecting linear light to an imaging object with relative motion; the image sensor is used for imaging based on the reflected light of the linear light and sending an effective signal with a timestamp when the change of the light passing quantity received by each pixel in unit time exceeds a threshold value; and a processor for calculating surface depth information of the imaging object based on the pixel position and the timestamp that report the valid signal, and the relative motion information. According to the invention, active light imaging is carried out on an imaging object with relative motion by using linear light, imaging is carried out only aiming at the changed effective signals by combining with an image sensor which can independently generate the effective signals when the brightness of each pixel changes, and position determination of depth data is carried out by using a timestamp and relative motion information. Therefore, high-speed depth information acquisition and processing are realized through a simple projection mechanism and extremely low computing power requirements.
公开了一种深度数据测量装置及其应用方法。测量装置包括投影组件，用于向在存在相对运动的成像对象投射线型光；图像传感器，用于基于线型光的反射光进行成像，并且每个像素在单位时间内接收到的通光量变化超过阈值时发送一个带时间戳的有效信号；以及处理器，用于基于报告有效信号的像素位置和时间戳、以及相对运动信息，计算成像对象的表面深度信息。本发明利用线型光对存在相对运动的成像对象进行主动光成像，结合各像素在亮度变化时能独立生成有效信号的图像传感器，仅针对发生变化的有效信号进行成像，并使用时间戳和相对运动信息进行深度数据的位置判定，从而以简单的投射机构和极低的算力需求实现高速深度信息获取和处理。
