[0002] The handheld surveying device integrates technologies such as single-point positioning, RTK positioning, 3D laser, remote positioning, and image measurement. It can automatically identify target outlines, locate target coordinates at long distances, and measure target height and width at long distances. It also records field survey data in real time, significantly reducing the workload of field personnel. Using field survey data and on-site images, the handheld surveying device can perform measurements and analyses of target points, lines, surfaces, and volumes.
[0003] However, the angle of the 3D laser module in the current handheld measuring device is not adjustable. When encountering a tall obstruction, the measuring operator's arm reaches the height of the obstruction after being raised. The operator's hand is blocked by the obstruction and cannot stably align the 3D laser module of the handheld measuring device with the direction of the object to be measured, which makes the measurement inconvenient. To address this issue, we provide a handheld target recognition optical measuring device to solve the above technical problems. Utility Model Content

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0034] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a handheld target recognition optical measurement device, which includes a handheld body 100 with high-precision GPS and Beidou positioning functions. A three-dimensional laser module unit 200 is adjustablely provided at one end of the handheld body 100. The three-dimensional laser module unit 200 includes a first bracket 201 and a second bracket 202 fixedly connected to one end of the handheld body 100. A mounting frame 203 is rotatably connected between the first bracket 201 and the second bracket 202 for adjusting the angle of the three-dimensional laser module 206 and the camera 207. The three-dimensional laser module 206 and the camera 207 are provided on one side of the mounting frame 203 for measuring information of objects.
[0035] The first bracket 201 has a connecting groove 2011 at one end. The mounting bracket 203 is fixedly connected to the first bracket 201 at the rotatable connection point. An adjusting rod 204 is used to adjust the angle of the mounting bracket 203. One end of the adjusting rod 204 passes through the connecting groove 2011. The second bracket 202 has a threaded groove 2021 at one end. A locking rod 205 is threaded into the threaded groove 2021 for locking or unlocking the mounting bracket 203.
[0036] The handheld device body 100 is equipped with a display screen 105 for displaying and operating information of the measured object. A protective shell 300 is rotatably connected to the side wall of the handheld device body 100 to protect the display screen 105 from being broken when the handheld device body 100 is dropped, and to protect the display screen 105 from rain during measurement in rainy weather, preventing rainwater from affecting the operator's vision or causing accidental touches. A torsion spring is provided at the rotatable connection point between the protective shell 300 and the handheld device body 100 to keep the protective shell 300 perpendicular to the display screen 105 in rainy weather. A first buckle 104 is fixedly connected to one end of the handheld device body 100, and a second buckle 301 is fixedly connected to one end of the protective shell 300. The protective shell 300 is closed by the cooperation of the first buckle 104 and the second buckle 301. The protective shell 300 is made of plastic and has a certain degree of elastic deformation to facilitate the operation of the first buckle 104 and the second buckle 301.
[0037] The handheld device body 100 has two sets of sliding grooves 101 symmetrically arranged inside. The two sets of sliding grooves 101 are located on both sides of the display screen 105. The handheld device body 100 also has a drain hole 102 and a drainage channel 103 inside. The drain hole 102 and the drainage channel 103 are connected to each other and are used to work with the sponge 403 to drain the rainwater on the display screen 105. The sliding groove 101 is equipped with a water removal unit 400 for removing the rainwater on the display screen 105. The water removal unit 400 includes two sets of sliding rods 402 symmetrically slidably connected in the two sets of sliding grooves 101. The two sets of sliding rods 402 are fixedly connected to the inside of the mounting plate 401. The sponge 403 is fixedly connected to the bottom of the mounting plate 401 for absorbing the rainwater on the display screen 105.
[0038] When using this device, in environments where the only convenient measurement is achieved by adjusting the angle of the 3D laser module 206 in the handheld target recognition optical measurement equipment, one hand rotates the locking lever 205 to loosen the mounting bracket 203 from the first support 201 and the second support 202. Then, the other hand rotates the adjusting lever 204, which in turn rotates the mounting bracket 203, causing the 3D laser module 206 to rotate. This continues until the 3D laser module 206 is adjusted to the desired measurement angle. Finally, the locking lever 205 is rotated in the opposite direction to lock the 3D laser module 206, allowing the next measurement step to proceed.
[0039] When it rains and staff do not have an umbrella, they hold the handheld device 100 vertically, rotate the 3D laser module 206 90 degrees to align it with the object to be measured, and then rotate the protective shell 300 90 degrees so that it is perpendicular to the display screen 105 to protect the display screen 105 from the rain. At this time, some rainwater on both sides of the protective shell 300 will fall onto the display screen 105. When there is more and more rainwater on the display screen 105, the mounting plate 401 is manually pulled up and down along the slide 101 several times. The mounting plate 401 drives the sponge 403 to move up and down together and absorb the rainwater on the display screen 105. Then, by pressing the sponge 403, the absorbed water is squeezed out and flows from the drain hole 102 to the drain trough 103 and then out of the drain trough 103.
