Fig. 1 illustrates a ranging method flowchart according to an exemplary embodiment of the present disclosure.
In step S101, the distance sensors are respectively acquired at the same position and at the same distance measurement angle, wherein the distance measurement angle is an angle between the distance sensor and the measured position, and the first distance is acquired for the first measured position and the second distance is acquired for the second measured position.
Alternatively, the distance sensor is a sensor that can determine the distance between the measured position and the current terminal device by means of the reflection time of ultrasonic waves, laser light, and infrared light, and by way of example, the distance sensor may be a time-of-flight TOF sensor. The flight time sensor comprises a transmitting module, a receiving module and a timing module. And the infrared light emitted by the emitting module is reflected by an object at the measured position and then transmitted back to the receiving module, the flight time of the laser is recorded by the timing module, and the distance between the current position and the measured position is calculated according to the flight time and the infrared propagation speed.
The first measured position and the second measured position are a starting point position and an ending point position of a distance which the user wants to measure, and can be any two positions of any two objects or any two measuring points of a single object in space.
The schematic diagram of obtaining the first measured distance and the second measured distance is shown in fig. 2:
after the first distance of the first measured position is acquired, the distance sensor needs to be kept at the same spatial position to acquire the second distance of the second measured position. Optionally, the position of the distance sensor may be kept fixed, and the terminal device is rotated with the position of the center point of the distance sensor as a center of sphere until the distance sensor can acquire a second distance of the second measured position at the same ranging angle, where the ranging angle is an angle between the distance sensor and the measured position.
In step S102, a rotation angle acquired by the motion sensor is acquired, where the rotation angle characterizes a pose state of the terminal device when the distance sensor acquires the second distance, and is opposite to a rotation angle of the pose state of the terminal device when the distance sensor acquires the first distance.
Optionally, the rotation angle between the motion sensor and the acquisition terminal equipment comprises an acceleration sensor and/or a geomagnetic sensor. The rotation angle is an angle through which the terminal equipment rotates in the process of rotating the terminal equipment by taking the position of the center point of the distance sensor as the center of a sphere. For an acceleration sensor, the rotation angle may be determined according to components of the gravitational acceleration along x, y, z axes of the terminal device; for the geomagnetic sensor, the rotation angle can be determined according to components of the magnetic field intensity along x, y and z axes of the terminal equipment, wherein the acceleration sensor is high in accuracy and can obtain the rotation angle in time, the geomagnetic sensor is low in power consumption, and at least one sensor can be selected according to specific requirements of the terminal equipment to obtain the rotation angle.
In step S103, a third distance between the first measured position and the second measured position is determined based on the first distance, the second distance, and the rotation angle.
Optionally, a triangle may be constructed by using the first measured position, the second measured position, and the position where the distance sensor is located as vertices, where, when the first distance, the second distance, and the rotation angle are acquired, a third distance between the first measured position and the second measured position may be determined according to a cosine law. Illustratively, the first distance is denoted as a, the second distance is denoted as b, and the rotation angle is denoted as C, the third distance C may be determined by the cosine law:
c 2 ＝a 2 +b 2 -2ab*cos C
according to the scheme, the third distance between the detected positions is determined through the first distance and the second distance acquired by the distance sensor and the rotation angle acquired by the motion sensor, so that a user can acquire distance information of two points in space at any time.
In an alternative embodiment, the terminal device is further provided with an image acquisition element for acquiring a ranging preview screen, so that a user can quickly select the measured position according to the preview screen. The measured position is used for representing the ranging angle of the distance sensor.
Specifically, in the method described in the present disclosure, one method for acquiring the first distance and the second distance is shown in fig. 3, and specifically includes steps S1021 to S1022.
In step S1021, the first distance is acquired for the first detected position in response to the first detected position being at a preset position of the ranging preview screen, wherein the detected position at the preset position is opposite to the distance sensor.
Alternatively, the user may position the terminal device perpendicular to the ground and position the distance sensor at the first measured position, i.e. the first measured position is located at the preset position. The measured position is relative to the distance sensor, and the current connecting line of the measured position and the distance sensor passes through the center of the distance sensor and is perpendicular to the receiving module of the distance sensor. The user can determine the first detected position by clicking on a screen, so that the distance sensor collects the first distance. Optionally, after the first distance is obtained, the terminal device may further display a first prompting message, configured to prompt a user to rotate the terminal device.
In step S1022, the second distance is acquired for the second detected position in response to the second detected position being at the preset position of the preview screen.
Optionally, the user rotates the terminal device to enable the distance sensor to be positioned at the second detected position, that is, enable the second detected position to be positioned at the preset position. The user can determine the second detected position by clicking on the screen, so that the distance sensor collects the second distance.
According to the scheme, through the preview picture acquired by the image acquisition element, a user can accurately and quickly determine the measured position, and when the first distance and the second distance are acquired through the preset position, the distance measurement angle is consistent.
In the method of the present disclosure, another method for acquiring the second distance is shown in fig. 4, and specifically includes steps S1022A to S1022B.
In step S1022A, in response to the rotation of the terminal device, a displacement parameter of the terminal device acquired by the motion sensor is acquired, where the displacement parameter characterizes a degree of positional deviation of the terminal device during the rotation.
Optionally, during the process of rotating the terminal device by the user, the acceleration acquired by the acceleration sensor may be integrated to acquire the displacement parameter of the terminal device, or the degree of the position deviation of the terminal device during the rotation process may be acquired by other motion sensors. In the method disclosed by the disclosure, when the first distance and the second distance are acquired, the distance sensor needs to be ensured to be at the same position, that is, the user needs to rotate the terminal device by taking the position of the center point of the distance sensor as the center of sphere. However, since the rotation of the handheld device is prone to operational errors, it is necessary to determine whether the distance sensor is severely shifted from the initial position according to the displacement parameter.
In step S1022B, the second distance is collected according to the displacement parameter of the terminal device and the positional relationship between the first detected position and the preset position in the preview screen.
Specifically, when the displacement parameter of the terminal device is smaller than or equal to a set threshold, the position deviation degree of the characterization distance sensor does not cause the calculation error of the third distance to exceed an acceptable range, and the second distance is acquired in response to the second measured position being located at the preset position of the preview picture.
And under the condition that the displacement parameter of the terminal equipment is larger than the set threshold value, the position deviation degree of the distance sensor is represented to be beyond an acceptable range. And displaying second prompt information, wherein the second prompt information is used for prompting a user to move the terminal equipment until the displacement parameter is smaller than or equal to a set threshold, namely, until the user restores the position of the terminal equipment to an initial position when the first distance is acquired, and acquiring the second distance through the distance sensor after the position of the distance sensor is determined to be unchanged.
According to the scheme, whether the position of the distance sensor is fixed or not is determined through the displacement parameter of the terminal equipment in the rotating process, and the user is prompted to restore the terminal equipment to the initial position under the condition that the displacement parameter is larger than the set threshold value, so that the position of the distance sensor is the same when the first distance and the second distance are acquired, and the reliability of a ranging result is improved.
For the foregoing method embodiments, for simplicity of explanation, the methodologies are shown as a series of acts, but one of ordinary skill in the art will appreciate that the present disclosure is not limited by the order of acts described, as some steps may occur in other orders or concurrently in accordance with the disclosure.
Further, those skilled in the art will also appreciate that the embodiments described in the specification are all alternative embodiments, and that the acts and modules referred to are not necessarily required by the present disclosure.
