In the embodiment of the present application, the single-point laser ranging module 120 may include a laser ranging sensor 121 and a printed circuit board 122, the printed circuit board 122 is fixed on the bracket 111, and the laser ranging sensor 121 is disposed on the printed circuit board 122 and the light emitting direction thereof deviates from the printed circuit board 122.
In this embodiment, the laser distance measuring sensor 121 may include a transmitting end and a receiving end, and when the laser distance measuring sensor 121 moves to a point location where a distance needs to be measured, an infrared pulse light wave is transmitted to an object by the transmitting end, then the receiving end receives the pulse light wave reflected back by the object, and finally the distance of the object is measured by comparing the received light wave with the transmitted light wave. The laser emitted by the infrared light source is near infrared light with the wavelength of 600-1550 nm.
In this application, single-point laser rangefinder module 120 sets up on support 111 in motion module 110, single-point laser rangefinder module 120 includes laser rangefinder sensor 121 and printed circuit board 122, and printed circuit board 122 is fixed on support 111, and control assembly 112 control support 111 removes, and then laser rangefinder sensor 121 can remove along with support 111 to obtain single-point laser rangefinder module 120's multiple spot range data, wherein, laser rangefinder sensor 121 can be fixed on printed circuit board 122 through modes such as welding.
In a possible implementation manner, the control assembly 112 in the embodiment of the present application may be formed by a coil and a permanent magnet, wherein the coil is disposed on an outer wall of the bracket 111, and the permanent magnet is disposed on the outer wall of the bracket 111 at an interval from the coil. In a specific implementation manner, the motion module 110 may adopt a reed structure similar to a reed Optical Image Stabilization (OIS) device, that is, a reed support bracket 111. Alternatively, a ball structure similar to a ball Optical Image Stabilization (OIS) device may be employed, i.e., the ball support bracket 111.
For example, if the moving module 110 is of a reed structure, when the Coil is not energized, the bracket 111 stays at the initial position and does not move due to the pulling force of the reed, when the Coil is energized, a magnetic field is generated, and the Coil and the magnetic field of the permanent magnet Magnets generate an interaction of force, so as to drive the bracket 111 to move in the X-axis direction and the Y-axis direction on the plane perpendicular to the light emitting direction of the laser ranging sensor 121, and the moving distance is in direct proportion to the magnitude of current, and the hall sensor (i.e., the position sensor) located below the bracket 111 is used for sensing the translation distance of the bracket 111 in the X-axis direction and the Y-axis direction and feeding back to the driving integrated circuit (Driver IC) to perform closed-loop control, and the effective strokes in the X-axis. When the Coil is de-energized, the bracket 111 is pulled by the spring and returns to the original position again.
If the motion module 110 is a ball structure, the operation principle of the motion module is similar to that of a reed structure, but the reed is replaced by a ball which slides in a slide way, so that the movement of the bracket 111 in the X-axis direction and the Y-axis direction on a plane perpendicular to the light emitting direction of the laser ranging sensor 121 is guided. After the power is off, the bracket 111 is at rest at the current position without returning to the initial position due to no external force.

In a specific implementation manner, the motion module 110 may adopt a structure similar to an Optical Image Stabilization (OIS) device made of Shape Memory Alloy (SMA), where the Shape Memory Alloy changes the temperature in the power-on state to change the Shape of the wire, so as to drive the support 111 to move.

This application embodiment combines through moving module 110 and single-point laser rangefinder module 120, and every removal of moving module 110 is once, single-point laser rangefinder module 120 can carry out laser rangefinder once and output range finding information to realize the function of multipoint laser rangefinder, and can not increase mobile terminal's consumption.
Fig. 2 is a schematic partial structure diagram of another mobile terminal disclosed in the embodiment of the present application. As shown in fig. 2, the mobile terminal disclosed in the embodiment of the present application may further include a first hall sensor 210, a second hall sensor 220, and a base 230. As shown in fig. 2, the first hall sensor 210 and the second hall sensor 220 are fixed on the base 230 below the bracket 111.

The moving position of the single-point laser ranging module 120 is detected by the hall sensor, so that the stability of the ranging information graph can be improved.
The single-point laser ranging module 120 is disposed in the accommodating cavity of the bracket 111, and if dust accumulates in the accommodating cavity of the bracket 111, the moving stroke and the ranging accuracy of the single-point laser ranging module 120 on the plane are affected, and therefore, further, the mobile terminal disclosed in this application may further include a laser sensor lens 310. As shown in fig. 3, the laser sensor lens 310 is disposed above the bracket 111, and the laser sensor lens 310 covers at least the receiving cavity of the bracket 111.

In addition to the light-blocking sheet 410, light-blocking foam may be used to reduce crosstalk between the transmitting end and the receiving end, as long as the light-blocking material is capable of reducing crosstalk between the transmitting end and the receiving end.
In another possible implementation manner, the mobile terminal disclosed in the present application may further include a laser sensor shield 510.

In addition, the current Time of Flight (TOF) is limited by resolution, power consumption and device size, and therefore the detection distance that can be achieved is less than 5m, but the mobile terminal provided by the application can increase power and size by using the laser ranging sensor 121, and can achieve a detection range of 10 m.
Based on the mobile terminal disclosed in the embodiment of the present application, an embodiment of the present application further discloses a method for acquiring ranging information, and as shown in fig. 6, the method for acquiring ranging information in the embodiment of the present application mainly includes the following steps.
S601, obtaining the scanning mode of the single-point laser ranging module 120.
The moving module 110 moves according to the obtained scanning mode of the single-point laser ranging module 120, and before determining the scanning mode of the single-point laser ranging module 120, the method further includes initializing the single-point laser ranging module 120 and the moving module 110.
And S602, respectively moving the single-point laser ranging module 120 to n target test points according to a scanning mode, wherein n is an integer larger than 1.
In this step, the single-point laser ranging module 120 is sequentially moved to n different target test points according to the scanning manner of the single-point laser ranging module 120, and the information obtained by the first hall sensor 210 and the second hall sensor 220 is read and sequentially detected. Before detection, whether the single-point laser ranging module 120 moves to the designated position or not is judged, if the single-point laser ranging module 120 moves to the designated position, detection is performed, and if the single-point laser ranging module 120 does not move to the designated position, the stroke of the motion module 110 needs to be adjusted, and the single-point laser ranging module 120 moves to the designated position and then detection is performed.
S603, obtaining ranging information of each target test point according to ranging data detected by the laser ranging sensor 121 in the single-point laser ranging module 120 at each target test point.
In this step, the ranging information of each target test point is obtained according to the ranging data detected by the laser ranging sensor 121 at each target test point, and then a ranging information map is formed. In addition, in the process, after the ranging information of one target test point is obtained, whether the current test point is the last test point needs to be judged, if the current test point is not the last test point, the ranging information is continuously detected and obtained, and if the current test point is the last test point, the test is finished.
In one possible implementation manner, the step S603 of detecting the ranging data at each target test point according to the laser ranging sensor 121 in the single-point laser ranging module 120 may include: and acquiring the ranging information of the target test point according to the time difference between the high-frequency laser pulse emitted by the laser ranging sensor 121 at the target test point and the reflected laser pulse received by the laser ranging sensor. Specifically, laser ranging generally uses two methods, namely a pulse method and a phase method, to measure the distance. The pulse method ranging generally refers to that a laser pulse emitted from an emitting end of the laser ranging sensor 121 is reflected by an object to be measured and then received by a receiving end of the laser ranging sensor 121, and the laser ranging sensor 121 simultaneously records round-trip time of the laser pulse, and half of the product of the light speed and the round-trip time is the distance between the laser ranging sensor 121 and the object to be measured. Laser ranging is one of the optical ranging methods, and if light travels in the air at a speed c and the time required for one round trip between two points A, B is t, the distance D between the two points A, B can be expressed as D ═ ct/2.
In a further technical solution, the scanning mode in S601 includes one of: progressive scanning, column-by-column scanning, and dot-by-dot scanning. For example, the stroke of the single-point laser ranging module 120 in the X-axis and Y-axis of the moving area on the plane perpendicular to the light emitting direction of the laser ranging sensor 121 is divided into N steps and M steps, the movement module 110 performs laser ranging once and outputs ranging information every time the movement module moves one Step, when the single-point laser ranging module 120 performs line-by-line scanning, the scanning result is M-line ranging information as shown in fig. 7a, when the single-point laser ranging module 120 performs line-by-line scanning, the scanning result is N-line ranging information as shown in fig. 7b, and when the single-point laser ranging module 120 performs point-by-point scanning, the scanning result is M × N discrete points as shown in fig. 7c, thereby implementing the multi-point laser function.
In this application, in S602, before the single-point laser ranging module 120 reaches n target test points in a scanning manner, the method further includes: the number n of the target test points is determined according to the application scenario and/or the power consumption of the mobile terminal, that is, the resolution of the ranging information map can be dynamically adjusted according to the requirement of the application scenario and/or the power consumption of the mobile terminal. For example, if the current application scene has a high requirement on the 3D information of the image, more target test points may be set, and for example, if the current power consumption of the mobile terminal is high, fewer target test points may be set.
In addition, the mobile terminal and the method for acquiring the ranging information provided by the application can also be combined with the current self-learning algorithm, the AI technology, the scene analysis and the semantic segmentation to realize the dynamic power adjustment of the single-point laser and reduce the power consumption.
