## Abstract

A translator pen and a translation method using same are provided. The translator pen includes a housing and a pen head. The housing forms a first accommodation cavity adapted to accommodate an image collector. An outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core. At least a portion of the end of the housing, which does not form the pen head, forms an inclined surface. The inclined surface is inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head. The image collector is configured to face the inclined surface.

## Claims

### Claim 1

A translator pen comprising a housing and a pen head at an end of the housing, wherein,
the housing forms a first accommodation cavity adapted to accommodate an image collector;
an outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core;
the pen head is formed at a portion of the end of the housing, and at least a portion of the end of the housing, which does not form the pen head, forms an inclined surface, the inclined surface being inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head, and the image collector is disposed on the inclined surface,
wherein the housing comprises a first housing and a second housing formed by snap-fit, and the first housing and the pen head are formed into an integral structure.

### Claim 2 (depends on 1)

The translator pen of claim 1, wherein the inclined surface is formed at an entire end of the housing, and the inclined surface is of an oval shape.

### Claim 3 (depends on 1)

The translator pen of claim 1, wherein the first accommodation cavity further comprises a trigger switch and a controller, the pen core comprises a pen tip away from one end of the housing, the pen tip is configured to indicate a word to be translated and transmit a received external force to the trigger switch to trigger the image collector to collect an image to be translated comprising the pen tip and the word to be translated indicated by the pen tip, so that the controller translates the word to be translated according to the image to be translated and outputs a translation result.

### Claim 4 (depends on 3)

The translator pen of claim 3, wherein a window is disposed on the inclined surface, the window corresponds to a viewfinder of the image collector disposed in the housing, and the image collector collects, by the viewfinder, the image to be translated comprising the pen tip and the word to be translated indicated by the pen tip through the window.

### Claim 5 (depends on 3)

The translator pen of claim 3, further comprising a cylindrical linkage structure connecting the pen core and the trigger switch, and the linkage structure transmits the external force received by the pen tip indicating the word to be translated to the trigger switch.

### Claim 6 (depends on 1)

The translator pen of claim 1, wherein the image collector comprises a camera,
an optical axis of the camera is parallel to an axial direction of a long axis of the pen core; or
the optical axis of the camera and the axial direction of the long axis of the pen core form an angle smaller than a preset degree.

### Claim 7 (depends on 1)

The translator pen of claim 1, wherein an end of the first accommodation cavity far from the pen head further comprises an antenna adapted to communicate with an external device, and the antenna is at an inner side of the housing.

### Claim 8 (depends on 7)

The translator pen of claim 7, wherein the antenna is a flexible circuit board structure electrically connected to the controller through a pin.

### Claim 9 (depends on 1)

The translator pen of claim 1, wherein an end of the first accommodation cavity far from the pen head further comprises an antenna adapted to communicate with an external device, and the antenna is attached to an inner wall of the housing.

### Claim 10

A translation method using a translator pen,
wherein the translator pen comprises a housing and a pen head at an end of the housing, wherein the housing forms a first accommodation cavity adapted to accommodate an image collector; an outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core; the pen head is formed at a portion of the end of the housing, and at least a portion of the end of the housing, which does not form the pen head, forms an inclined surface, the inclined surface being inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head, the image collector is disposed on the inclined surface, the first accommodation cavity further comprises a trigger switch and a controller, and the pen core comprises a pen tip far from one end of the housing,
wherein the method comprises:
a pen tip pressing step of pressing the pen tip close to a word to be translated, and transmitting a received external force to the trigger switch, which sends a trigger signal;
a photographing step of controlling, by the controller, the image collector to collect an image to be translated comprising the pen tip and the word to be translated indicated by the pen tip in response to the trigger signal;
an image preprocessing step of preprocessing a collected image to be translated to obtain a processed image;
a text detection step of marking an image area with words on the processed image to select a target image area where the word to be translated is located;
a character recognition step of performing character recognition on the target image area to obtain the word to be translated;
a translation step of translating the word character to obtain a translation result; and
a result output step of outputting the translation result.

### Claim 11 (depends on 10)

The translation method using the translator pen of claim 10, wherein
the image preprocessing step at least comprises one or a plurality of the following steps: resolution adjustment, image cropping, image rotation, and image distortion correction.
