Multi-Object Grasp Detection Dataset

Dataset for robotic grasping with multiple objects per scene. Contains RGB images, depth maps, and grasp annotations for various objects.

Dataset Details

• Total samples: 96 scenes
• Objects: Various household items (screwdriver, pliers, scissors, wrench, etc. - in russian)
• Grasps per scene: Multiple grasp poses per object
• Image resolution: 640x480 pixels

Grasp Annotation Format. Each grasp is represented as a quadrilateral with 4 vertices:

{
    'grasp_id': int,
    'center': [xc, yc],           # Center of grasp rectangle
    'opening_point': [xo, yo]      # Gripper opening point
}

Usage

from datasets import load_dataset

ds = load_dataset("vadim-vlm4vla/grasp_multiObject_upgrade")

example = ds['test'][0]

print(f"Image ID: {example['image_id']}")
print(f"Number of objects: {example['num_objects']}")
print(f"Total grasps: {example['num_grasps']}")

example['image'].show()

for obj in example['objects']:
    print(f"\nObject: {obj['object_name']}")
    print(f"  Grasps: {len(obj['grasps'])}")
    for grasp in obj['grasps']:
        print(f"    Grasp {grasp['grasp_id']}:")
        print(f"      Center: {grasp['center']}")
        print(f"      Opening: {grasp['opening_point']}")

Visualization Example

import matplotlib.pyplot as plt
import numpy as np

example = ds['test'][0]
image = np.array(example['image'])

fig, ax = plt.subplots(1, 1, figsize=(10, 8))
ax.imshow(image)

colors = plt.cm.rainbow(np.linspace(0, 1, example['num_objects']))

for obj_idx, obj in enumerate(example['objects']):
    color = colors[obj_idx]
    for grasp in obj['grasps']:
        center = grasp['center']
        opening = grasp['opening_point']
        
        # Draw center point
        ax.plot(center[0], center[1], 'o', color=color, markersize=8)
        
        # Draw line to opening point
        ax.plot([center[0], opening[0]], [center[1], opening[1]], 
               '-', color=color, linewidth=2)
        
        # Draw opening point
        ax.plot(opening[0], opening[1], 's', color=color, markersize=6)

plt.title(f"Image {example['image_id']} - {example['num_objects']} objects, {example['num_grasps']} grasps")
plt.axis('off')
plt.show()
