HANDHELD DEVICE, OBJECT POSITIONING METHOD AND COMPUTER-READABLE RECORDING MEDIUM
First Claim
1. A handheld device, comprising:
- a radar sensor, emitting a first detection wave, and receiving at least one reflected wave generated by at least one object by reflecting the first detection wave, wherein each of the at least one object generates one of the at least one reflected wave;
an image sensor, capturing a first image, wherein the first image comprises a subset of the at least one object; and
a control unit, coupled to the radar sensor and the image sensor, extracting a waveform signature of each of the at least one reflected wave, respectively recognizing the waveform signature in a time domain and a frequency domain to determine a first type of each of the at least one object, obtaining a first position of each of the at least one object according to the at least one reflected wave, obtaining a second type and a second position of each of the at least one object according to the first image, and performing a mapping operation based on the first type, the second type, the first position and the second position of each of the at least one object to combine or compare the first position and the second position.

Abstract
A handheld device, an object positioning method thereof and a computer-readable recording medium are provided. The handheld device includes a radar sensor, an image sensor and a control unit. The radar sensor emits a detection wave, and receives a reflected wave generated by an object by reflecting the detection wave. Each object generates one of the reflected waves. The image sensor captures an image. The image includes a subset of the objects. The control unit extracts a waveform signature of each reflected wave, recognizes the waveform signature in a time domain and a frequency domain to determine a first type of each object, obtains a first position of the object according to the reflected wave, obtains a second type and a second position of each object according to the first image, and performs object mapping to combine or compare the first position and the second position of the object.
