Embodiment Construction

[0018] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0019] Such as Figure 4 As shown, an efficient power control method of an active depth sensor in the present invention includes the following process: obtaining prior information of the environment to be tested; presetting the prior information of the environment to be measured in the corresponding active depth sensor ; The active depth sensor calculates the position information and orientation information of the active sensor according to the preset prior information of the environment to be tested and the detection information obtained by real-time detection, and searches for the corresponding depth-power curve to obtain The maximum transmit power and then adjust its transmit power.

[0020] The above active depth sensor can be applied to various smart devices.

[0021] combine figure 1 and figure 2 As sh...

Abstract

The invention discloses a depth sensor, a detection system and a method for controlling the transmission power of the sensor. The method comprises the following steps: acquiring priori information ofa working environment to be tested; presetting the prior information of the working environment to be tested; performing calculation according to the preset priori information of the working environment to be tested and detection information to obtain position information and orientation information of an active sensor; calculating maximum transmission power according to the position information and the orientation information of the active sensor, and correspondingly dynamically adjusting the transmission power of the active depth sensor according to the maximum transmission power. The depthsensor, the detection system and the method for controlling the transmission power of the sensor have the advantages that the transmission power is intelligently dynamically adjusted and controlled and the power consumption of a device provided with the active depth sensor is reduced.

Description

technical field [0001] The invention relates to the technical field of sensor detection, in particular to an active depth sensor, a detection system and a method for controlling the transmission power of the active depth sensor. Background technique [0002] The depth sensor provides the device with information about the user's position and posture, as well as information about the three-dimensional shape of the environment surrounding the depth sensor. Depth sensors fall into two categories: passive stereo cameras and active depth cameras. Passive stereo cameras observe a scene with two or more cameras and use the displacement between features in the multiple views of these cameras to estimate the depth of the scene. Active depth cameras project invisible infrared light onto the scene and, based on the reflected information, estimate the depth of the scene. [0003] For artificial intelligence fields such as robots, unmanned driving, and intelligent hardware, the use of s...
